5. John Maynard Keynes
Capitalism Faces Its Greatest Challenge
A thousand years hence 1920–1970 will, I expect, be the time for
historians. It drives me wild to think of it. I believe it will make my
poor Principles, with a lot of poor comrades, into waste paper.1
—Alfred Marshall (1915)
Keynes was no socialist—he came to save capitalism, not to
bury it. . . . There has been nothing like Keynes’s
achievement in the annals of social sciences.
—Paul Krugman (2006)
The capitalist system of natural liberty—founded by Adam Smith,
revised by the marginalist revolution, and refined by Marshall, Fisher,
and the Austrians—was under siege. The classical virtues of thrift,
balanced budgets, low taxes, the gold standard, and Say’s law were
under attack as never before. The house that Adam Smith built was
threatening to collapse.
The Great Depression of the 1930s was the most traumatic economic
event of the twentieth century. It was especially shocking given
the great advances achieved in Western living standards during the
New Era twenties. Those living standards would be strained during
1929–33, the brunt of the depression. In the United States, industrial
output fell by over 30 percent. Over one-third of the commercial
banks failed or consolidated. The unemployment rate soared to over
25 percent. Stock prices lost 88 percent of their value. Europe and
the rest of the world faced similar turmoil.
The Austrians Mises and Hayek, along with the sound-money
economists in the United States, had anticipated trouble, but felt
helpless in the face of a slump that just wouldn’t go away. A nascent
recovery under Roosevelt’s New Deal began in the mid-1930s, but
didn’t last. U.S. unemployment remained at double-digit levels for a
full decade and did not disappear until World War II. Europe didn’t
fare much better; only Hitler’s militant Germany was fully employed
as war approached. In the free world, fear of losing one’s job, fear of
hunger, and fear of war loomed ominously.
The length and severity of the Great Depression caused most of
the Anglo-American economics profession to question classical laissez-
faire economics and the ability of a free-market capitalist system
to correct itself. The assault was on two levels—the competitive
nature of capitalism (micro) and the stability of the general economy
(macro).
Was the Classical Model of Competition Imperfect?
On the micro level, two economists simultaneously wrote books
that independently challenged the classical model of competition. In
1933, Harvard University Press released The Theory of Monopolistic
Competition by Edward H. Chamberlin (1899–1967), and Cambridge
University Press published Economics of Imperfect Competition by
KEYNES RESPONDS TO CAPITALISM’S GREATEST CHALLENGE 135
Joan Robinson (1903–83). Both economists introduced the idea that
there are various levels of competition in the marketplace, from “pure
competition” to “pure monopoly,” and that most market conditions
were “imperfect” and involved degrees of monopoly power. The
Chamberlin-Robinson theory of imperfect competition captured
the imagination of the profession and has been an integral feature
of microeconomics ever since. It has strong policy implications:
Laissez-faire is defective and cannot ensure competitive conditions
in capitalism; the government must intervene through controls and
antitrust actions to curtail the natural monopolistic tendencies of
business.
The Radical Threat to Capitalism
But this threat was minor compared to the radical noncapitalist
alternatives being proposed in macroeconomics. Marxism was all
the rage on campuses and among intellectuals during the 1930s.
Paul Sweezy, a Harvard-trained economist, had gone to the London
School of Economics (LSE) in the early 1930s, only to return
a full-fledged Marxist, ready to teach radical ideas at his alma
mater. Sidney and Beatrice Webb returned from the Soviet Union
brimming with optimism, firm in their belief that Stalin had inaugurated
a “new civilization” of full employment and economic
superiority. Was full-scale socialism the only alternative to an
unstable capitalist system?
Who Would Save Capitalism?
More sober intellectuals sought an alternative to wholesale socialism,
nationalization, and central planning. Fortunately, there was a
powerful voice urging a middle ground, a way to preserve economic
liberty without the government taking over the whole economy and
destroying the foundations of Western civilization.
It was the voice of John Maynard Keynes, leader of the new
Cambridge school. In his revolutionary 1936 book, The General
Theory of Employment, Interest and Money, Keynes preached that
capitalism is inherently unstable and has no natural tendency toward
full employment. Yet, at the same time, he rejected the need to na136
tionalize the economy, impose price-wage controls, and interfere
with the microfoundations of supply and demand. All that was
needed was for government to take control of a wayward capitalist
steering wheel and get the car back on the road to prosperity. How?
Not by slashing prices and wages—the classical approach—but
by deliberately running federal deficits and spending money on
public works that would expand “aggregate demand” and restore
confidence. Once the economy got back on track and reached full
employment, the government would no longer need to run deficits,
and the classical model would function properly. As Keynes himself
wrote, “But beyond this no obvious case is made out for a system
of State Socialism which would embrace most of the economic life
of the community” (Keynes 1973a [1936], 378). His message was
really quite simple, yet revolutionary: “Mass unemployment had a
single cause, inadequate demand, and an easy solution, expansionary
fiscal policy” (Krugman 2006).
Keynes’s model of aggregate demand management changed the
dismal science to the optimists’ club: man could be the master of
his economic destiny after all. His claim that government could expand
or contract aggregate demand as conditions required seemed
to eliminate the cycle inherent in capitalism without eliminating
capitalism itself. Meanwhile, a laissez-faire policy of economic
freedom could be pursued on a microeconomic level. In short,
Keynes’s middle-of-the-road policies were viewed not as a threat
to free enterprise, but as its savior. In fact, Keynesianism brought
its chief rival theory, Marxism, to a total halt in advanced countries
(Galbraith 1975 [1965], 132).
“Like a Flash of Light on a Dark Night”
The Keynesian revolution took place almost overnight, especially
among the youngest and the brightest, who switched allegiance from
the Austrians to Keynes. John Kenneth Galbraith wrote of the times,
“Here was a remedy for the despair. . . . It did not overthrow the
system but saved it. To the non-revolutionary, it seemed too good to
be true. To the occasional revolutionary, it was. The old economics
was still taught by day. But in the evening, and almost every evening
from 1936 on, almost everyone discussed Keynes” (Galbraith 1975
[1965], 136). Milton Friedman, who later became a vociferous opponent
of Keynesian theory, said, “By contrast with this dismal picture
[the Austrian laissez-faire prescription], the news seeping out of
Cambridge (England) about Keynes’s interpretation of the depression
and of the right policy to cure it must have come like a flash of light
on a dark night. It offered a far less hopeless diagnosis of the disease.
More importantly, it offered a more immediate, less painful, and more
effective cure in the form of budget deficits. It is easy to see how a
young, vigorous, and generous mind would have been attracted to
it” (1974, 163).
The Keynesian model of aggregate demand management swept the
profession even faster than the marginalist revolution, especially after
World War II seemed to vindicate the benefits of deficit spending and
massive government spending. It wasn’t long before college professors,
under the tutorage of Alvin Hansen, Paul Samuelson, Lawrence
Klein, and other Keynesian disciples, began teaching students about
the consumption function, the multiplier, the marginal propensity to
consume, the paradox of thrift, aggregate demand, and C + I + G. It
was a strange, new, exciting doctrine. And it was the beginning of a
whole new area of study called “macroeconomics.”2
The Dark Side of Keynes
Keynes may have offered a plausible cure for the depression, but
his theoretical heresies also created a postwar environment favorable
toward ubiquitous state interventionism, the welfare state, and
boundless faith in big government. His theories encouraged excess
consumption, debt financing, and progressive taxation over saving,
balanced budgets, and low taxes. Critics saw Keynesian economics
as a direct assault on traditional economic values and the most serious
threat to the principles of economic freedom since Marxism.
To them, Keynes’s General Theory “constitutes the most subtle and
mischievous assault on orthodox capitalism and free enterprise that
has appeared in the English language” (Hazlitt 1977 [1960], 345). As
Paul Krugman notes, “If your doctrine says that free markets, left to
their own devices, produce the best of all possible worlds, and that
government intervention in the economy always makes things worse,
Keynes is your enemy” (Krugman 2006).
Despite occasional pronouncements that Keynes is dead, Keynesian
thinking is still so pervasive in academia, the halls of parliament,
and Wall Street, that Time magazine aptly voted Keynes the most
influential economist of the twentieth century. Biographer Charles
Hession writes, “More books and articles have been written about
him than any other economist, with the possible exception of Karl
Marx” (1984, xiv). Appropriately, The New Palgrave gives Keynes its
longest biography—twenty pages, as compared to fifteen for Marx.
And Keynes’s latest biographer, Robert Skidelsky, places Keynes
on a pedestal: “Keynes was a magical figure, and it is fitting that he
should have left a magical work. There has never been an economist
like him” (1992, 537).
Keynes Born Amid Britain’s Ruling Elite
What kind of man was Keynes, who could engender such devotion
and such hostility?
John Maynard Keynes (1883–1946) was an intellectual elitist
from his earliest childhood. When asked once how to pronounce his
name, he replied, “Keynes, as in brains.” Born in 1883 (the year Marx
died) in the center of Britain’s most cerebral environment, he was the
son of John Neville Keynes, an economics professor at Cambridge
University and a friend of Alfred Marshall. Neville would actually
outlive his son, Maynard, by three years, dying in 1949 at age ninetyseven.
His mother, Florence Ada Keynes, also distinguished herself
as Cambridge’s first woman mayor. Keynes was always close to his
mother, while his father was distant. His father wrote in his diary in
1891, when Maynard was only eight years old, “The only person he
would like to be is his mother; at any rate, he would desire to resemble
her in everything” (in Hession 1984, 11).
Keynes went to Britain’s best private school, Eton, and then attended,
as expected, Cambridge University, where he obtained a
degree in mathematics in 1905. He would later write a controversial
book on probability theory.
His friends considered him precocious, clever, and sometimes
rude. His most distinguishing features were his “riotous eyes” and
“leaping mind” (Skidelsky 1992, xxxi). Keynes viewed himself
as “physically repulsive.” Nevertheless, he was selected as one of
only a dozen members of the Apostles, an exclusive secret society
at Cambridge (not unlike the Skull and Bones at Yale). Membership
is for life. Other noteworthy members have included the poet
Alfred Lord Tennyson, biographer Lytton Strachey, and philosophers
Bertrand Russell, G.E. Moore, and Alfred North Whitehead. The
Apostles were a close-knit group, meeting every Saturday night to
discuss papers.
The Truth About Keynes’s Homosexuality
At the turn of the twentieth century, the Apostles, under the influence
of G.E. Moore, developed a deep contempt for Victorian morality
and bourgeois values. They even propounded the subversive idea
that homosexuality was morally superior. Keynes was a practicing
homosexual during his early adult life, although he apparently
abandoned it upon marrying Lydia Lopokova in 1925. This fact was
covered up by his official biographer, Roy Harrod, for fear it would
destroy Keynes’s reputation. In his introduction, Harrod explained,
“In regard to his faults, I am not conscious of any suppression [of
facts]. Criticisms have been made by the malicious or ill-informed
which have no foundation in fact” (Harrod 1951, viii). Yet there
was suppression. More recent histories by Robert Skidelsky (2003),
D.E. Moggridge (1992), and Charles Hession (1984) spare few details
of Keynes’s sexual adventures. Moggridge even goes so far as
to print Keynes’s sexual engagement diary in an appendix (1992,
838–39).
Keynes’s sexual proclivities may have been influenced by his
family life (overprotective mother, weak father); the Eton school, an
all-male institution where Greek philosophy taught that platonic love
between men is spiritually higher than the carnal love between man
and woman; and the collegiate ideas of G.E. Moore, who preached
a disregard for morals and universal rules of conduct. Keynes firmly
believed in living the “good life,” without concern for right or wrong.
“[It] is too late to change. I remain, and will always remain, an immoralist,”
he wrote (Hession 1984, 46).
Was Keynes a misogynist? Keynes’s predilection for men may
have affected his attitudes toward women in his early years. Like
Marshall, he disliked the presence of female students in his classes.
In 1909, while teaching at Cambridge, he wrote, “I think I shall have
to give up teaching females after this year. The nervous irritation
caused by two hours’ contact with them is intense. I seem to hate
every movement of their minds. The minds of the men, even when
they are stupid and ugly, never appear to me so repellent” (Moggridge
1992, 183–34).
But Keynes shocked his homosexual friends in Bloomsbury
when he announced his engagement and subsequent marriage to
Lydia Lopokova, a Russian ballerina, in 1925. Based on private
letters between Maynard and Lydia, their marriage was far from
platonic. “Sexual relations certainly developed,” biographer Robert
Skidelsky writes (1992, 110–11; 2003, 300, 356–60). Keynes
also developed friendships with women in the 1930s, including
Joan Robinson.
But we are getting ahead of our story. After graduation, Keynes
entered the British Civil Service, spending two years in the India office
(although never visiting India). In 1909 he became a teaching fellow
at Cambridge, and from 1911 to 1944 he served as the general editor
of Cambridge’s Economic Journal. He was not trained in economics,
having taken only a single course from Alfred Marshall, but quickly
acquired the skills to teach it.
Keynes Writes a Best-Seller
In 1919, following World War I, Keynes served as a senior Treasury
official in the British delegation to the Versailles Peace Conference.
Distressed by the proceedings, he resigned and wrote The Economic
Consequences of the Peace (1920). It became a best-seller and propelled
Keynes into fame and fortune.
Many critics consider it Keynes’s best book. Writing in trenchant
prose, he revealed peculiar personal characteristics of the Allied
leaders.3 Keynes condemned the Allies for imposing impractical and
unrealistic reparations on the Germans. The defeated nations were
required to pay the complete Allied costs of the war, including pay,
pensions, and death benefits of troops—up to $5 billion “whether
in gold, commodities, ships, securities or otherwise,” before May 1,
1921. “The existence of the great war debts is a menace to financial
stability everywhere,” warned Keynes (1920, 279). A pessimistic
Keynes predicted negative consequences in Europe. He implied
that Germany would have no recourse but to inflate her way out. In
a famous passage, Keynes noted, “Lenin was certainly right. There
is no subtler, no surer means of overturning the existing basis of
society than to debauch the currency. The process engages all the
hidden forces of economic law on the side of destruction, and does
it in a manner which not one man in a million is able to diagnose”
(1920, 236).4
Keynes Makes Another Brilliant Prediction in 1925
Keynes followed this success with another insightful analysis in 1925
when Britain, under Chancellor of the Exchequer Winston Churchill,
returned to the gold standard at the overvalued prewar fixed exchange
rate of $4.86. Keynes campaigned against this deflationary measure.
In his booklet The Economic Consequences of Mr. Churchill, the Cambridge
professor warned that deflation would force Britain to reduce
real wages and retard economic growth (Keynes 1951 [1931], 244–70).
Once again, Keynes proved prescient; Britain suffered from an economic
malaise that only worsened as the Great Depression approached.
Unfortunately, Keynes’s gift of prophecy disappeared in the late
1920s. In his Tract on Monetary Reform (which Milton Friedman rates as
Keynes’s greatest work), he joined the monetarist Irving Fisher in rejecting
the gold standard, and later hailed the stabilizing influence of the U.S.
dollar between 1923 and 1928 as a “triumph” of the Federal Reserve.
“We Will Not Have Any More Crashes in Our Time”
Like Fisher, Keynes was a New Era advocate who was bullish on stocks
and commodities throughout the 1920s. In 1926, he met with Swiss
banker Felix Somary, anxious to buy stocks. When Somary expressed
pessimism about the future of the stock market, Keynes declared firmly,
“We will not have any more crashes in our time” (Somary 1986 [1960],
146–47). Somary had been trained in Austrian economics at the University
of Vienna and knew that the New Era boom was unsustainable.
But Keynes, like Irving Fisher, ignored the Austrians and pinned his
hopes on the Federal Reserve and price stabilization.
In late 1928, Keynes wrote two papers disputing that a “dangerous
inflation” was developing on Wall Street, concluding that there was
“nothing which can be called inflation yet in sight.” Referring to both real
estate and stock values in the United States, Keynes added, “I conclude
that it would be premature today to assert the existence of over-investment.
. . . I should be inclined, therefore, to predict that stocks would not slump
severely (i.e., below the recent low level) unless the market was discounting
a business depression.” Such would not be probable, he wrote, since
the Federal Reserve Board would “do all in its power to avoid a business
depression” (Keynes 1973b, 52–59; Hession 1984, 238–39).
KEYNES RESPONDS TO CAPITALISM’S GREATEST CHALLENGE 143
Making Money from His Bedroom
Keynes should not have been so confident. By the late 1920s, he
had developed a reputation for financial wizardry trading currencies,
commodities, and stocks. He was chairman of the National Mutual
Life Insurance Company and bursar of King’s College in Cambridge.
His personal account included a heavy commitment to commodities
and stocks. He held long positions in futures contracts in rubber,
corn, cotton, and tin, as well as several British automobile stocks.
Indeed, he was known for making trading decisions while still in
bed. Reports Hession, “Some of this financial decision-making was
carried out while he was still in bed in the morning; reports would
come to him by phone from his brokers, and he would read the newspapers
and make his decisions” (Hession 1984, 175).
Keynes Is Wiped Out by the Crash
Tragically, Keynes misread the times and failed to anticipate the crash.
His portfolio was almost wiped out: he lost three-quarters of his net
worth, primarily due to commodity losses (Moggridge 1983, 15–17;
Skidelsky 1992, 338–43). In his Treatise on Money, published in 1930,
he admitted that he had been misled by stable price indices in the
1920s, and that a “profit inflation” had developed (1930, 190–98).
However, Keynes, a stubborn investor, held onto his stocks and added
substantially to his portfolio starting in 1932. Although he was incapable
of getting out at the top, he had an uncanny ability to acquire stocks at
the bottom of the market (Skousen 1992, 161–69). He bought securities
that were clearly out of favor, such as utilities and gold stocks, and
was so sure of his strategy that he bought heavily on margin. In 1944,
he wrote a fellow money manager, “My central principle of investment
is to go contrary to general opinion, on the ground that, if everyone
is agreed about its merits, the investment is inevitably too dear and
therefore unattractive” (Moggridge 1983, 111).
Keynes Still Manages to Die Spectacularly Rich
Keynes was so spectacularly successful in choosing stocks that his
net worth reached £411,000 by the time he died in 1946. Given that
his portfolio was worth only £16,315 in 1920, that’s a 13 percent
compounded annual return, far superior to what most professional
money managers achieve and an amazing feat during an era when
there was little or no inflation and, in fact, much deflation. And
this extraordinary return was achieved despite fantastic setbacks in
1929–32 and 1937–38. Only David Ricardo had a superior record as
a financial economist.
A Revolutionary Book Appears
Keynes’s failure to predict the crash and the Great Depression deeply
influenced his thinking. He was bitterly resentful of the speculators
who drove prices down to ridiculously low levels and nearly put
him in the poorhouse. He had long before rejected laissez-faire as a
general organizing principle in society, but the 1929–33 crisis only
strengthened his rejection of conventional classical economics. In
BBC radio addresses, he lashed out at hoarders, speculators, and gold
bugs, while urging deficit spending, inflation, and abandonment of
the gold standard as solutions to the slump. He criticized Friedrich
Hayek and the London School of Economics for believing that the
economy was self-adjusting and for urging wage reductions and balanced
budgets as solutions to the depression.
All the while, at his home in Cambridge, Keynes was working on
a book creating a new model of economics, with the help of Richard
Kahn, Joan Robinson, and the Cambridge Circus that developed
around him. On New Year’s Day 1935, Keynes wrote playwright
George Bernard Shaw, “I believe myself to be writing a book on
economic theory, which will largely revolutionise—not, I suppose, at
once but in the course of the next ten years—the way the world thinks
about economic problems” (Skidelsky 2003, 518). It was an arrogant
prognostication, but one that proved to be right.
As already mentioned, The General Theory of Employment, Interest
and Money first appeared in 1936.5 Like other economists,
Keynes identified with the great scientists of the past. Adam Smith
and Roger Babson compared their analytical systems to those of
Sir Isaac Newton, and Keynes emulated Albert Einstein. Keynes’s
book title refers to Einstein’s general theory of relativity. His book,
he said, created a “general” theory of economic behavior while he
relegated the classical model to a “special” case and treated classical
economists as “Euclidean geometers in a non-Euclidean world”
(Skidelsky 1992, 487).
Like Marx, Keynes had high hopes that his magnum opus would be
read by students and the general public and convinced Macmillan to
price the 400-page treatise at only five shillings. But this was wishful
thinking. The General Theory turned out to be Keynes’s only unreadable
book, full of technical jargon and incomprehensible language.
Ricardo and Marx had their book of headaches and so did Keynes. The
following simple Q and A will demonstrate a few of the difficulties
found in The General Theory. (Thanks to Roger Garrison, economics
professor at Auburn University, for providing this bit of satire.)
Keynes’s Book of Headaches
Q: Please, Professor Keynes, what do you mean by “involuntary
unemployment”?
A: “My definition is . . . as follows: Men are involuntarily unemployed
if, in the event of a small rise in the price of wage-goods relative
to the money-wage, both the aggregate supply of labour willing to
work for the current money-wage and the aggregate demand for it at
that wage would be greater than the existing volume of employment”
(1973a [1936], 15).
Q: Humm . . . sounds very enlightening, Professor Keynes. Now tell
us, please, what governs private investment in a market economy?
A: “Our conclusions can be stated in the most general form . . . as
follows: No further increase in the rate of investment is possible when
the greatest amongst the own-rates of own-interest of all available
assets is equal to the greatest amongst the marginal efficiencies of all
assets, measured in terms of the asset whose own-rate of own-interest
is greatest” (236).
Q: Yes, I see. . . . One last question, Professor Keynes. Doesn’t
monetary expansion trigger an artificial boom?
A: “[A]t this point we are in deep water. The wild duck has dived
down to the bottom—as deep as she can get—and bitten fast hold
of the weed and tangle and all the rubbish that is down there, and it
would need an extraordinarily clever dog to dive down and fish her
up again” (183).
Even Paul Samuelson, a devote Keynesian, declared, “It is a badly
written book, poorly organized; any layman who, beguiled by the
author’s previous reputation, bought the book was cheated of his
five shillings. It is not well suited for classroom use. It is arrogant,
bad-tempered, polemical, and not overly generous in its acknowledgements.
It abounds in mares’ nests or confusions. . . . Flashes
of insight and intuition intersperse tedious algebra. An awkward
definition suddenly gives way to an unforgettable cadenza. When
finally mastered, its analysis is found to be obvious and at the same
time new. In short, it is a work of genius” (Samuelson 1947 [1946],
148–89).6
And Paul Krugman writes that “although The General Theory
is still worth reading and rereading,” he admits that he “labored
through” parts of it, and finds it helpful to describe the book as “a
meal that begins with a delectable appetizer and ends with a delightful
dessert, but whose main course consists of rather tough meat”
(Krugman 2006).
The General Theory is still in print, but only because of the elucidating
work of Keynes’s disciples, especially Alvin Hansen and Paul
Samuelson, who deciphered Keynes’s convoluted jargon, translated
it into plain English, and transformed the profession.
Keynes at War
Keynes was fifty-two when he completed The General Theory, his
final major work. He was at the height of his powers. Keynes was
never a bookish scholar and recluse like his Cambridge colleagues
Arthur Pigou or Dennis Robertson. He was a man of worldly affairs
who loved the limelight and the social life, enjoyed the company of
writers and artists, and was a devotee of cards, roulette, and speculations
on Lombard Street and Wall Street. His magnetic personality
attracted the highest leaders of government, who sought his counsel.
He was a master of the written word and an entertaining speaker who
regularly appeared on BBC radio.
After suffering a heart attack in 1937, Keynes had to slow down.
He and his wife became active in promoting the arts and establishing
the Arts Theatre in Cambridge. In 1940, when the war with Germany
broke out, Keynes returned to the Treasury as an advisor and wrote
an influential booklet, How to Pay for the War. He recommended
restrictions on consumption and investment, and a forced savings
program as a way to reduce demand and inflation.
In May 1942, Keynes’s name was submitted to the king, nominating
him to become Baron Keynes of Tilton, and in July he took his seat in
the House of Lords. On his sixtieth birthday, Keynes was made High
Steward of Cambridge, an honorary post. He thrived on the adulation
and elitist status.
Near the end of the war, Keynes and his wife traveled to the United
States to help negotiate a new international financial agreement. Keynes
was one of the architects of the Bretton Woods agreement, which established
a fixed exchange rate system based on gold and the dollar and
created the International Monetary Fund (IMF) and the World Bank.
Two years later, he died of a heart attack at the age of sixty-two.
Keynes’s Disdain for Karl Marx and Marxism
Let us now turn to Keynes’s approach to economics. It should be
noted at the outset that Keynes had serious reservations about the
economics of both Adam Smith and Karl Marx. The most influential
economist of the twentieth century, Keynes was an interventionist
and a supporter of Britain’s Labour Party. Like Marx, he was no
friend of laissez-faire. He argued that capitalism was inherently
unstable and required government intervention. But that was as far
as it went. Keynes couldn’t stand Karl Marx or the communist experiment,
which he regarded as “an insult to our intelligence” (Mog
gridge 1992, 470; Skidelsky 1992, 519; 2003, 514–18). Following
a trip to Russia in 1925, Keynes wrote three articles for the Nation,
debunking the Soviet “religion” as “unscrupulous,” “ruthless,” and
“contrary to human nature.” There was none of that naïve “I’ve seen
the future” optimism for Keynes. Individual freedom and a liberal
open society meant too much to him. “For me, brought up in a free
air undarkened by the horrors of religion, with nothing to be afraid
of, Red Russia holds too much which is detestable.” He added, “How
can I adopt a creed which, preferring the mud to the fish, exalts the
boorish proletariat above the bourgeois and the intelligentsia who,
with whatever faults, are the quality in life and surely carry the
seeds of all human achievement? . . . We have everything to lose by
the methods of violent change. In Western industrial conditions the
tactics of Red Revolution would throw the whole population into a
pit of poverty and death” (1951 [1931], 306). He lambasted Marx’s
magnum opus, Capital, as “an obsolete economic textbook” that
was “scientifically erroneous” and “without interest or application
for the modern world” (298–300).
In the middle of the Great Depression, the best and the brightest
intellectuals embraced Marxism, but not Keynes. At a dinner among
friends in 1934, Keynes said that, of all the “isms,” Marxism was “the
worst of all & founded on a silly mistake of old Mr Ricardo’s [labor
theory of value]” (Skidelsky 2003, 515). In a letter to playwright
George Bernard Shaw, Keynes labeled Das Kapital “dreary, outof-
date, academic controversialising.” He compared it to the Koran.
“How could either of these books carry fire and sword round half the
world? It beats me.” In a second letter to Shaw dated January 1, 1935,
Keynes complained of Marx’s “vile manner of writing” (Skidelsky
1992, 520; 2003, 517).7
Keynes’s Critique of Adam Smith and His Invisible
Hand Doctrine
Keynes has been lauded as the savior of capitalism, but his model
and policy recommendations were in many ways a direct repudiation
and assault on Adam Smith’s laissez-faire system. In the New
Era twenties he wrote, “It is not true that individuals possess a
prescriptive ‘natural liberty’ in their economic activities. . . . Nor
is it true that self-interest generally is enlightened. . . . Experience
does not show that individuals, when they make up a social unit, are
always less clear-sighted than when they act separately” (Keynes
1951 [1931], 312). This speech, appropriately titled, “The End of
Laissez-Faire,” was given in 1926, a full decade before The General
Theory was written. It was a clear attack on Adam Smith’s system
of natural liberty.
In the early 1930s, Keynes became increasingly disillusioned
with capitalism, both morally and aesthetically. The ideas of Sigmund
Freud were fashionable at the time, and Keynes adopted the
Freudian thesis that moneymaking was a neurosis, “a somewhat
disgusting morbidity, one of the semi-criminal, semi-pathological
propensities which one hands over with a shudder to specialists in
mental disease” (1951 [1931], 369). Later, in 1933, he indicted the
capitalist system: “The decadent international but individualistic
capitalism, in the hands of which we found ourselves after the war,
is not a success. It is not intelligent, it is not beautiful, it is not just,
it is not virtuous—and it doesn’t deliver the goods. In short, we dislike
it and are beginning to despise it. But when we wonder what
to put in its place, we are perplexed” (Hession 1984, 258). This is
a far cry from Adam Smith!
Keynes, the Heretic, Turns Classical Economics
Upside Down
The General Theory did not aim to rebuild the classical model; it
aimed to replace it with elaborate unconventional concepts and a
new Weltanschauung. Until the 1930s, the economics profession had
largely sanctioned the basic premises of the classical model of Adam
Smith—the virtues of thrift, balanced budgets, free trade, low taxes,
the gold standard, and Say’s law. But Keynes turned the classical
model upside down.
Instead of Smith’s classical system being considered the general
or universal model, Keynes relegated it to a “special case,” applicable
only in times of full employment. His own general theory of “aggregate
effective demand” would apply during times of underemployed labor
and resources, which, under Keynesianism, could exist indefinitely.
Under such circumstances, Keynes offered the following principles:
1. An increase in savings can contract income and reduce
economic growth. Consumption is more important than
production in encouraging investment, thus reversing Say’s
law: “Demand creates its own supply” (1973a [1936],
18–21, 111).
2. The federal government’s budget should be kept deliberately
in a state of imbalance during a recession. Fiscal and monetary
policy should be highly expansionary until prosperity
is restored, and interest rates should be kept permanently low
(128–31, 322).
3. Government should abandon its laissez-faire policy and intervene
in the marketplace whenever necessary. According
to Keynes, in desperate times it may be necessary to return
to mercantilist policies, including protectionist measures
(333–71).
4. The gold standard is defective because its inelasticity renders it
incapable of responding to the expanding needs of business. A
managed fiat money is preferable (235–56; 1971, 140). Keynes
held a deep-seated disdain for the gold standard and was largely
successful in dethroning gold as a worldwide monetary numeraire.
What Did Keynes Really Mean by “In the Long Run We
Are All Dead”?
Keynes’s cavalier statement, “In the long run we are all dead,” is in
many ways a symbol of his turning his back on classical economics.
Many economists consider his remark an affront to Frédéric Bastiat’s
classical view (“What Is Seen and What Is Not Seen”) that economists
must take into account the long-run and not just the short-run effects
of government policies. For example, deficit spending may stimulate
certain sectors of the economy in the short run, but what will be the
impact in the long run? Tariffs may save some manufacturing jobs, but
what impact will this have on consumers? As Henry Hazlitt declares,
“The art of economics consists in looking not merely at the immediate
but at the longer effects of any act or policy; it consists in tracing the
consequences of that policy not merely for one group but for all groups”
(1979 [1946], 17). And Ludwig von Mises, another critic of Keynes,
concludes, “we have outlived the short-run and are suffering from the
long-run consequences of [Keynesian] policies” (1980 [1952], 7).
Keynes may have indeed used his dictum to support short-term policies
like deficit spending, but he also used it in other contexts.
Keynes Attacks Monetarism
The first time Keynes made the famous remark quoted above, he used
it to deride Irving Fisher’s extreme monetarism, which claimed that
monetary inflation has no ill effects in the long run but only raises
prices (see chapter 4). Keynes retorted, “Now ‘in the long run’ this
is probably true . . . but this long run is a misleading guide to current
affairs. In the long run we are all dead. Economists set themselves
too easy, too useless a task if in tempestuous seasons they can only
tell us that when the storm is long past the ocean is flat again” (1971,
65). No doubt Hazlitt and Mises would find much to agree with in
this statement.
Britain First!
Keynes also used his famous phrase in the context of British foreign
policy in wartime. In 1937, when Churchill advocated rearmament
and warned against appeasing Hitler, Keynes seemed to support
short-term peace initiatives: “It is our duty to prolong peace, hour
by hour, day by day, for as long as we can. . . . I have said in another
context that it is a disadvantage of ‘the long run’ that in the long
run we are all dead. But I could have said equally well that it is a
great advantage of ‘the short run’ that in the short run we are still
alive. Life and history are made up of short runs. If we are at peace
in the short run, that is something. The best we can do is put off
disaster” (Moggridge 1992, 611). Was Keynes advocating peace at
any price?
After Pearl Harbor was attacked in December 1941, Keynes reacted
with dismay to the British Foreign Office argument that free
trade with America would be beneficial to Britain “in the long run.”
Keynes blustered, “The theory that ‘to get our way in the long run’ we
must always yield in the short reminds me of the bombshell I threw
into economic theory by the reminder that ‘in the long run we are all
dead.’ If there was no one left to appease, the F.O. [Foreign Office]
would feel out of a job altogether” (Moggridge 1992, 666). This was
Keynes the mercantilist.
Keynes’s Long Term
Keynes was truly a social millennialist who ultimately envisioned
a world evolving to the point of infinite accumulation of capital.
His utopian vision is best expressed in his essay, “Economic Possibilities
for Our Grandchildren” (1951 [1931], 358–73). Keynes
believed that by progressively expanding credit to promote full employment,
the universal economic problem of scarcity would finally
be overcome. Interest rates would fall to zero and mankind would
reenter the Garden of Eden. In Keynes’s mind, the gold standard
severely limited credit expansion and preserved the status quo of
scarcity. Thus, gold’s inelasticity—which the classical economists
considered its primary virtue—stood in the way of Keynes’s paradise
and needed to be abandoned in favor of fiat-money inflation (1951
[1931], 360–73). The Bretton Woods agreement was the first step
toward removing gold from the world’s monetary system. Keynes
would undoubtedly be pleased to see gold playing such a moribund
role in international monetary affairs in the twenty-first century.
In short, Keynes’s goal was not to save Adam Smith’s house, as his
adherents contended, but to build another house entirely—the house
that Keynes built. It was his belief that economists would live and
work most of the time in Keynes’s house, while using Smith’s house
occasionally, perhaps as a vacation home.
Is Capitalism Inherently Unstable?
Keynes rejected the classical notion that the capitalist system is
self-adjusting over the long run. The General Theory was written
specifically to create a model based on the view that the market
system is inherently and inescapably flawed. According to Keynes,
capitalism was unstable and therefore could become stuck indefinitely
at varying degrees of “unemployed equilibrium,” depending on
the level of uncertainty in a fragile financial system. Keynes wanted
to show that the economy could remain “in a chronic condition of
sub-normal activity for a considerable period without any marked
tendency either toward recovery or toward complete collapse” (1973a
[1936], 249, 30). Paul Samuelson correctly understood the meaning
of Keynes: “With respect to the level of total purchasing power and
employment, Keynes denies that there is an invisible hand channeling
the self-centered action of each individual to the social optimum”
(Samuelson 1947, 151).
Keynes explained what he meant by “unemployment equilibrium,”
but used no diagram to illustrate it. In a masterful article, “Mr. Keynes
and the Classics,” British economist John Hicks developed a graphic
framework (known as the IS-LM diagram) to demonstrate Keynes’s
version of full-employment equilibrium (the special classical theory)
versus unemployment equilibrium (the general theory) (Hicks 1937).
Today’s textbooks use a similar diagram to demonstrate aggregate supply
(AS) and aggregate demand (AD).
In Figure 5.1 we see how the economy is depressed at less than
full employment. According to Keynes’s model, the classical model
only applies when the economy reaches full employment (Qf), while
the Keynesian general theory applies at any point along the AS curve
where it intersects with the AD curve.
Who’s to Blame? Irrational Investors!
Keynes blamed the instability of capitalism on the bad behavior
of investors. The General Theory creates a macroeconomic model
based essentially on a financial instability hypothesis. As Keynesian
economist Hyman P. Minsky declares, “The essential aspect
of Keynes’s General Theory is a deep analysis of how financial
forces—which we can characterize as Wall Street—interact with
production and consumption to determine output, employment, and
prices” (1986, 100). Allan H. Meltzer at Carnegie Mellon University
offers a similar interpretation, that Keynes’s theory of employment
and output was not so much related to rigid wages and prices as to
expectations and uncertainty in the investment and capital markets
(Meltzer 1988 [1968]).8
Numerous passages in The General Theory support this view.
Keynes complained of the irrational short-term “animal spirits” of
speculators who dump stocks in favor of liquidity during such crises.
Such “waves of irrational psychology” could do much damage to
long-term expectations, he said. “Of the maxims of orthodox finance
none, surely, is more anti-social than the fetish of liquidity, the doctrine
that it is a positive virtue on the part of investment institutions to
concentrate resources upon the holding of ‘liquid’ securities” (1973a
[1936], 155). According to Keynes, the stock market is not simply
an efficient way to raise capital and advance living standards, but can
be likened to a casino or a game of chance. “For it is, so to speak, a
game of Snap, of Old Maid, of Musical Chairs—a pastime in which
he is victor who says Snap neither too soon nor too late, who passes
the Old Maid to his neighbor before the game is over, who secures a
chair for himself when the music stops” (1973a [1936], 155–56).
Keynes was speaking from experience. He reasoned that the
1929–33 crisis destroyed his portfolio without any rational economic
cause—the panic was due to Wall Street’s irrational demand for cash,
what he termed “liquidity preference” and a “fetish of liquidity”
(1973a [1936], 155).
The Culprit: Uninvested Savings
If Keynes were Sherlock Homes, the economist-investigator would
point an accusing finger at Miss Thrifty in his murder mystery,
“The Case of the Missing Savings.” In Keynes’s model, the key
factor causing an indefinite slump is the de-linking of savings and
investment. If savings failed to be invested, total spending in the
economy would fall to a point below full employment. If savings
were hoarded or left in excessive reserves in the banks, as was the
case in the 1930s, the fetish for liquidity would make national investment
and output fall. Thus, thrift no longer served as a dependable
social function.
In The General Theory, Keynes argued that as income and wealth
accumulate under capitalism, the threat grows that savings will not
be invested. He introduced a “psychological law” that the “marginal
propensity to save” increases with income (1973a [1936], 31, 97).
That is, as individuals earn more income and become wealthier, they
tend to save a greater percentage of their income. Thus, there is a
strong tendency for savings to rise disproportionately as national
income increases. But wouldn’t a growing capitalist economy always
be under pressure to invest those increased savings? Keynes
responded, “Maybe, maybe not.” If savings are not invested, the
boom will turn into a bust.
Actually, this criticism of uninvested saving is an old saw with
Keynes. He acknowledged the necessity of thrift and self-denial during
the nineteenth century in a delightful passage of The Economic
Consequences of the Peace (1920, 18–22), stating that thrift “made
possible those vast accumulations of fixed wealth and of capital improvement
which distinguished that age from all others” (19). But
in A Treatise on Money (1930), the Cambridge economist raised the
likely possibility that saving and investment could grow apart, creating
a business cycle. In a modern society, saving and investing are done
by two separate groups. Saving is a “negative act of refraining from
spending,” while investment is a “positive act of starting or maintaining
some process of production” (1930, 155). The interest rate is not
an “automatic mechanism” that brings the two together—they can
“get out of gear” (1951 [1931], 393) and savings can be “abortive.”
If investment exceeds savings, a boom occurs; if savings exceeds
investment, a slump happens.9
During the depression of the 1930s, Keynes lashed out at frugal
savers and hoarders who kept down “effective demand.” The conventional
wisdom in bad times has always been to cut costs, get out
of debt, build a strong cash position, and wait for a recovery. Keynes
was opposed to this “old-fashioned” approach, and he was joined by
other economists, including British Treasury official Ralph Hawtrey
and Harvard’s Frank Taussig, in encouraging consumers to spend. In a
radio broadcast in January 1931, Keynes asserted that thriftiness could
cause a “vicious circle” of poverty, that if “you save five shillings, you
put a man out of work for a day.” He encouraged British housewives
to go on a buying spree and government to go on a building binge.
He urged, “Why not pull down the whole of South London from
Westminster to Greenwich, and make a good job of it. . . . Would that
employ men? Why, of course it would!” (1951 [1931], 151–54).
Keynes’s bias against thrift reached its zenith in The General Theory,
where he referred to traditional views on savings as “absurd.” He boldly
wrote, “The more virtuous we are, the more determined by thrift, the
more obstinately orthodox in our national and personal finance, the
more our incomes will fall” (1973a [1936], 111, 211). Keynes praised
the heterodox notions of underworld figures and monetary cranks, such
as Bernard de Mandeville, J.A. Hobson, and Silvio Gessell, who held
underconsumptionist views (333–71). He was undoubtedly influenced
by the popularity of Major Douglas of the social credit movement and
underconsumptionists Foster and Catchings during the 1920s.
An Antisaving Tradition
Keynes was not the first to question the virtue of thrift. Over the years,
a small group of radical thinkers, known generally as underconsumptionists,
have dissented from the traditional endorsement of thrift.
They include Simonde de Sismondi, Karl Rodbertus, J.A. Hobson,
and Karl Marx. Keynes expressed sympathy toward the “heretical”
views of Major C.H. Douglas, an engineer who began the social credit
movement in Canada in the 1920s and wrote several books championing
“economic democracy” (1973a [1936], 370–71). Believing that
saving created a permanent deficiency in a nation’s purchasing power,
Major Douglas advocated strict below-market price controls so that
consumers could afford to buy the products they produced.
William T. Foster, past president of Reed College, and Waddill
Catchings, an iron manufacturer and partner in the investment firm of
Goldman Sachs, proposed a different scheme. Foster and Catchings
wrote a series of books on a similar antisaving theme. “[E]very dollar
which is saved and invested, instead of spent, causes one dollar of
deficiency in consumer buying unless that deficiency is made up in
some way” (Foster and Catchings 1927, 48). What way? Foster and
Catchings advocated that the government issue new money credits to
consumers to make up for consumer buying deficiency.
158 THE BIG THREE IN ECONOMICS
To generate interest in their theory and proposal, in 1927 they offered
a prize of $5,000 to anyone who could refute them. They published the
best essays a few months later, but the best critique was written by the
Austrian economist Friedrich A. Hayek in 1929. His essay, “The ‘Paradox’
of Saving,” was translated and published in Economica in May 1931.
According to Hayek, the Foster-and-Catchings dilemma depended on
a single erroneous assumption. They assumed a “single-stage” model,
so that investment depends entirely and immediately on consumer
demand. Under such a restrictive assumption, “there would be no inducement
[for consumers] . . . to save money . . . [or] . . . to invest their
savings,” noted Hayek (1939 [1929], 224, 247). With a capital-using,
time-oriented period of production, Hayek demonstrated that increased
savings lengthens the capitalistic process, increases productivity, and
thereby enlarges profits, wages, and income sufficiently for consumers
to buy the final product.10
Keynes Focuses on Spending as the Key Ingredient
In Keynes’s mind, saving is an unreliable form of spending. It is only
“effective” if savings are invested by business. Thus, savings that are
hoarded under a mattress or piled up in a bank vault are a drain on
the economy and aggregate demand.
Only “effective demand”—a powerful new term introduced in
chapter 3 of The General Theory—counts. What consumers and businesses
spend determines national output. Keynes defined effective
demand as aggregate output (Y), which is the sum of consumption
(C) and investment (I). Hence,
Y = C + I
Today we refer to Y, or “aggregate effective demand,” as gross domestic
product (GDP). GDP is defined as the value of final output of goods and
services during the year. Simon Kuznets, a Keynesian statistician, developed
national income accounting in the early 1940s as a way to measure
Keynes’s aggregate effective demand. Keynes effectively demonstrated
that if savings are not invested by business, GDP does not reach its potential;
recession or depression indicates a lack of effective demand.
Demand Creates Its Own Supply
What was Keynes’s solution to recession? Increase effective demand!
If demand is stimulated through additional spending, more goods have
to be produced and the economy should recover. In this sense, Keynes
turned Say’s law upside down. Demand creates supply, not the other
way around.
To increase Y (national output), the choices are limited in a recession.
During a downturn, the business community might be afraid
to risk its capital on I (investment). Equally, consumers might be
unwilling to increase consumption (C) due to the uncertainty of their
incomes. Both investors and consumers are more likely to pull in their
horns when left to their own devices.
Adding G to the Equation
There is only one way out, wrote Keynes. Get government to start
spending. Keynes added G (government) to the national income
equation, so that
Y = C + I + G
Keynes saw government (G) as an independent agent capable of
stimulating the economy through the printing presses and public
works. An expansionary government policy could raise “effective
demand” if resources were underutilized, and it could do so without
hurting consumption or investment. In fact, during a recession, a rise
in G would encourage both C and I and thereby boost Y.
Digging Holes in the Ground: Keynes Endorses an
Activist Fiscal Policy
Keynes overturned the classical solution to a slump, which had
been to “tighten one’s belt” by cutting prices, wages, and wasteful
spending while waiting out the slump. Instead, during a recession,
he recommended deliberate deficit spending by the federal government
to jump-start the economy. He endorsed an even more radical
approach during a deep depression like that of the 1930s: government
spending could be totally wasteful and it would still help.
“Pyramid-building, earthquakes, even wars may serve to increase
wealth,” he proclaimed (1973a [1936], 129). Of course, “It would,
indeed, be more sensible to build houses and the like,” but productive
building was not essential. According to Keynes, spending is
spending, no matter what the objective, and it has the same beneficial
effect—increasing aggregate demand.
Keynes Favors Public Works over Monetary Inflation
Keynes felt that tinkering with fiscal policy (changes in spending and
taxes) was more effective than monetary policy (changes in the money
supply and interest rates). He had lost faith in monetary policy and
the Federal Reserve in the 1930s, when interest rates were so low that
reducing them wouldn’t have made much difference (see Figure 5.2).
Inducing the Federal Reserve to expand the money supply would not
be very effective either, because banks refused to lend excess reserves
anyway. Keynes called this a “liquidity trap.” The new money would just
pile up unspent and uninvested because of “liquidity preference,” the
desire to hold cash during a severe depression (1973a [1936], 207).
How the Multiplier Generates Full Employment
Public works would serve several benefits. First, public works are
positive spending, putting people to work and money into business’s
pockets. Moreover, they have a multiplier effect, based on the nation’s
marginal propensity to consume.
The multiplier, a concept introduced by Richard Kahn, was a powerful
new tool in the Keynesian tool box, demonstrating that a “small increment
of investment will lead to full employment” (Keynes 1973a [1936], 118).
Suppose in a recession that the government hires construction workers
and suppliers to construct a new federal building costing $100 million.
These previously unemployed workers are now getting paid. In the first
round of spending, $100 million is added to the economy.
Now suppose that the public’s marginal propensity to consume is 90
percent, that is, these workers spend 90 cents of every new dollar earned.
(Another way of saying it: their marginal propensity to save is 10 percent.)
In the second round of spending, $90 million is added to the economy.
Then there is a third round. After the workers spend their new
money, that $90 million becomes the revenues of other businesses—
shopping malls, gas stations, supermarkets, car dealerships, and movie
theaters. These business may in turn hire new workers to handle the
new demand, paying them more wages, too, and these workers also
spend 90 percent of that income. They receive an additional $81 million
(90 percent of $90 million) of spending power. Ultimately, the
public investment has a multiplier effect that generates round after
round of gradually declining spending. By the time the new spending
has run its course, the aggregate spending has increased tenfold.
Keynes’s formula for the multiplier (k) is,
1
k = __________
1 – MPC
where MPC = marginal propensity to consume.
Figure 5.2 The General Theory Was Written When Interest Rates Were at
Their All-Time Lows
Since MPC = .90 in the example above, k = 10. As Keynes stated,
“the multiplier k is 10; and the total employment caused by . . .
increased public works will be ten times the primary employment
provided by the public works themselves, assuming no reduction of
investment in other directions” (1973a [1936], 116–17).
Keynes Makes a Mischievous Assumption
Note that in the Keynesian model, only consumption spending generates
additional income and employment in the economy. Keynes assumes
that saving is sterile, that it aborts into cash hoarding or excess
bank reserves. Thus, the Keynesian model as originally proposed is
considered a “depression” model. As we shall see in the next chapter,
this was a crucial mistake that led to much mischief and misunderstanding
in economics in the postwar era.
Keynes Offers a Drastic Measure to Stabilize Capitalism
The Cambridge leader was not satisfied with temporary measures such
as public works and deficit spending to reestablish full employment.
Once maximum output was reached, he reasoned, there is no reason to
believe it will stay there. Investment is unpredictable and ephemeral,
Keynes said. Long-term expectations, a stable business climate, and
savings equal to investment could never be guaranteed as long as irrational
“animal spirits” operated in a laissez-faire financial marketplace.
What was Keynes’s solution? He favored a gradual but comprehensive
“socialisation of investment” as the “only means of securing an approximation
to full employment” (1973a, 378). This was by no means
“state socialism,” but it could mean government ownership of the entire
capital market. Keynes also sanctioned a small “transfer tax” on all
securities sales as a way to dampen speculative fever.11
6
A Turning Point in
Twentieth-Century Economics
Keynsesian economics is . . . the most serious blow that the
authority of orthodox economics has yet suffered.
—W.H. Hutt (1979, 12)
Two factors created the right atmosphere for the Keynesian revolution
to sweep the economics profession after World War II. First, the depth
and length of the Great Depression seemed to justify the Keynesian-
Marxian view that market capitalism was inherently unstable and that
the market could be stuck at unemployed equilibrium indefinitely.
Economic historians noted that the only governments that appeared to
make headway in eliminating unemployment in the 1930s were totalitarian
regimes in Germany, Italy, and the Soviet Union. Curiously, Keynes
himself acknowledged in the introduction to the German edition of The
General Theory, that his theory “is much more easily adapted to the
conditions of a totalitarian state, than is the theory of the production and
distribution of a given output produced under conditions of free competition
and a large measure of laissez-faire” (1973a [1936], xxvi).
Second, World War II came along right after the publication of The
General Theory, giving strong empirical evidence of Keynes’s policy
prescription. Government spending and deficit financing increased
dramatically during World War II, unemployment disappeared, and
economic output soared. War was “good” for the economy, just as
Keynes suggested (1973a [1936], 129). As historian Robert M. Collins
wrote, “World War II set the stage for the triumph of Keynesianism
by providing striking evidence of the effectiveness of government
expenditures on a huge scale” (1981, 12). The following quote from
a popular textbook repeated what other textbooks were saying in the
postwar period: “Once the massive, war-geared expenditure of the
1940s began, income responded sharply and unemployment evapo164
rated. Government expenditures on goods and services, which had
been running at under 15 percent of GNP during the 1930s, jumped
to 46 percent by 1944, while unemployment reached the incredible
low of 1.2 percent of the civilian labor force” (Lipsey, Steiner, and
Purvis 1987, 573).
Paul Samuelson Raises the Keynesian Cross
As noted earlier, Keynes died in 1946, right after the war. It would
be left to his disciples to lead the charge and create a “new economics.”
Fortunately for Keynes, a young wunderkind was ready to fill
his shoes. His name was Paul Samuelson, and he would write a
textbook that would dominate the profession for more than an entire
generation.
The year was 1948, one of those watershed years that occasionally
crops up in economics. Remember 1776, 1848, and 1871? In early
1948, the Austrian émigré Ludwig von Mises, secluded in his New
York apartment, was typing a short article, “Stones into Bread, the
Keynesian Miracle,” for a conservative publication, Plain Talk. “What
is going on today in the United States,” he declared solemnly, “is the
final failure of Keynesianism. There is no doubt that the American
public is moving away from the Keynesian notions and slogans. Their
prestige is dwindling” (Mises 1980 [1952], 62).
Perhaps it was wishful thinking, but Mises could not have misread
the times more egregiously in 1948. It was in that very year that the
new economics of John Maynard Keynes was being hailed by Keynes’s
rapidly growing number of disciples as the wave of the future and
the savior of capitalism. Literally hundreds of articles and dozens
of books had been published about Keynes and the new Keynesian
model since Keynes wrote The General Theory of Employment, Interest
and Money.
The Other Cambridge
The year 1948 was also when Seymour E. Harris, chairman of the
economics department at Harvard, produced an edited volume entitled
Saving American Capitalism. This was a sequel to his 1947 edited
work, The New Economics. Both best-sellers were filled with laudaA
tory articles by prominent economists preaching the new economics
of Keynes.
Darwin had one bulldog to propagate his revolutionary theory,
but Keynes had three in the United States—Seymour Harris, Alvin
Hansen, and Paul A. Samuelson. They all came from the “other Cambridge”—
Cambridge, Massachusetts. Both Harris and Hansen were
conservative Harvard teachers who had converted to Keynesianism
and devoted their energies to convincing students and colleagues of
the efficacy of this strange new doctrine.
The American advancement of Keynesian economics represented a
subtle but clear shift from Europe to the New World. Before the war,
London and Cambridge in the United Kingdom shaped the economic
world. After the war, the magnets for the best and the brightest graduate
students were Boston, Chicago, and Berkeley. Students came from
all over the world to do their work in the United States, and not just
in economics.
The Year of the Textbook
Finally, 1948 was the year in which an exciting new breakthrough
textbook came forth from Harvard’s neighboring university, the Massachusetts
Institute of Technology (MIT). Written by the “brash whippersnapper
go-getter” Paul Samuelson (his own words!), Economics
was destined to become the most successful textbook ever published
in any field. Sixteen editions have sold more than 4 million copies
and have been translated into over forty languages. No other textbook,
including those of Jean-Baptiste Say, John Stuart Mill, and Alfred Marshall,
can compare. Samuelson’s Economics survived a half-century of
dramatic changes in the world economy and the economics profession:
peace and war, boom and bust, inflation and deflation, Republicans
and Democrats, and an array of new economic theories.
Samuelson’s textbook was popular not so much because it was
well written, but because it elucidated and simplified the basics of
Keynesian macroeconomics through the deft use of simple algebra
and clear graphs. It took the profession by storm, selling hundreds
of thousands of copies every year. Samuelson updated the textbook
every three years or so, a practice that every textbook publisher now
imitates. Economics sold over 440,000 copies at the height of its
popularity in 1964. Even a conservative institution such as Brigham
Young University, my alma mater, used the Samuelson textbook.
The Acme of Professional Success
Samuelson is known for more than just popularizing Keynesian economics.
He is considered the father of modern macroeconomic theorizing.
He has made innumerable contributions to pure mathematical
economics, for which he has been both honored and blamed—honored
for making economics a pure logical science, and blamed for carrying
the Ricardian vice and Walrasian equilibrium analysis to an extreme,
devoid of any empirical work. (See chapters 2 and 4.)
For his popular and scientific works, the academic community
has awarded Samuelson virtually every honor it confers. He was the
first American to win the Nobel Prize in economics, in 1970. He was
awarded the first John Bates Clark Medal for the brightest economist
under forty, and beyond economics, he received the Albert Einstein
Medal in 1971. There’s even an annual award named after him, the
Paul A. Samuelson Award, given for published works in finance. His
articles have appeared in all the major (and many minor) journals. He
was elected president of the American Economic Association (AEA),
has received innumerable honorary degrees from various universities,
and has been the subject of many Festschrifts, gatherings at which
scholars honor a fellow colleague with essays about his work.
“The Young, Brash Wunderkind”
Paul A. Samuelson was born in Gary, Indiana, in 1915 to Jewish parents,
and moved to Chicago, where he received his B.A. in 1935—at
the tender age of twenty—from the University of Chicago. Chicago
in the 1930s, as it is today, was the citadel of laissez-faire economic
thought. In those days, it was run by Frank Knight, Jacob Viner, and
Henry Simons, among others. Paul’s first class in economics was
taught by Aaron Director, who was perhaps the most libertarian among
the faculty and who later became Milton Friedman’s brother-in-law.
Both Friedman and George Stigler were graduate students at the
time. Director’s laissez-faire philosophy failed to take in the youthful
reformist Samuelson, who enjoyed being an intellectual heretic in a
conservative institution and who was influenced by a father known as
a “moderate socialist.” Moreover, during the depression, most of the
leaders of the Chicago school advocated deficit spending and other
government activist policies as temporary measures. Samuelson did
inherit one concept from Chicago that he carried with him until he
encountered Keynes—monetarism. He called himself a “jackass” for
having been taken in (Samuelson 1968, 1).
Alvin Hansen Switches Sides to Become the
“American Keynes”
After Chicago, Samuelson immediately went to Harvard, where he
witnessed an amazing transition. His teacher, Alvin Hansen (1887–
1975), a long-standing classical economist, converted to Keynesianism.
Most older economists at first rejected Keynes’s heretical ideas,
including Hansen, who was at the University of Minnesota. Only
Marriner Eccles, the exceptional Utah banker who became head of the
Federal Reserve, and Lauchlin Currie, an economic aide to Roosevelt,
were prominent Keynesian advocates.
Then, in the fall of 1937, Hansen transferred to Harvard and suddenly—
at the age of fifty—recognized the revolutionary nature of
Keynes. He would become an outspoken exponent—the “American
Keynes.” His fiscal policy seminar attracted many enthusiastic students,
including Samuelson, and convinced many colleagues, including
Seymour Harris. Keynes had to be translated into plain English and
easy-to-understand graphs and math, and Hansen was the principal
interpreter, from Fiscal Policy and Business Cycles (1941) to A Guide
to Keynes (1953). Hansen also campaigned for the Employment Act
of 1946. According to Mark Blaug, “Alvin Hansen did more than
any other economist to bring the Keynesian Revolution to America”
(Blaug 1985, 79).
“Stagnation Thesis” Discredits Hansen and Almost
Destroys Samuelson’s Reputation
However, Hansen fell into a trap. He logically extended Keynes’s
unemployment equilibrium theory into a “secular stagnation thesis.”
(Keynes himself believed that conditions of the 1930s could persist
indefinitely.) In his presidential address before the AEA in 1937,
Hansen boldly announced that the United States was stuck in a “mature
economy” rut from which it could not escape, due to its lack of
technological innovations, the American frontier, and the population
growth rate. His stagnation thesis was vigorously attacked by George
Terborgh in his book The Bogey of Economic Maturity (1945) and then
soundly disproved by a vibrant recovery after World War II. The stigma
of this unfulfilled prediction haunted Hansen throughout his life.
Paul Samuelson, under the Hansen stagnation spell, almost suffered
the same fate. In 1943, he wrote an article warning that unless the
government acted vigorously after the end of the war, “there would
be ushered in the greatest period of unemployment and industrial
dislocation which any economy has ever faced.” In a two-part article
in published in The New Republic in the autumn of 1944, Samuelson
predicted a replay of the 1930s depression (Sobel 1980, 101–02).
Although he, along with most Keynesians, was proved inaccurate
about the postwar period, Samuelson gradually began expressing
strong optimism about the U.S. economy in successive editions of
his textbook. “Our mixed economy—wars aside—has a great future
before it” (1964, 809).
Samuelson found it an exciting time to be an economist: “To have
been born as an economist before 1936 was a boon—yes. But not to
have been born too long before!” (in Harris 1947, 145). He applied
the following familiar lines from William Wordsworth’s The Prelude
(Book 11, lines 108-9, previously quoted in chapter 2):
Bliss was it in that dawn to be alive,
But to be young was very Heaven!
Samuelson completed his dissertation in 1941, and it won the David
A. Wells Award that year. (It was published in 1947 as Foundations
of Economic Analysis.) In this work, Samuelson broke with Alfred
Marshall by contending that mathematics, not literary expression,
should be the primary exposition of economics.
But after graduation Samuelson discovered that heaven was not so
sweet. He declared his preference to teach at Harvard, but his youthful
exuberance, arrogant personality, and Jewish background all worked
against him. His cocky attitude had long irritated his chairman, Harold
Hitchings Burbank, and the department offered him only an instructorship.
Determined to stay in Cambridge, he accepted a position at the
relatively unheralded department of economics at the Massachusetts
Institute of Technology.
Harvard soon came to regret its mistake. By 1947, Samuelson had
been awarded the first John Bates Clark Medal for being the brightest
young economist, his school had granted him a full professorship,
and MIT had been ranked as one of the best economics departments
in the country. And Samuelson was only thirty-two! A year later he
would drop the bomb that would be the envy of every economics
department: the first edition of Economics, Samuelson’s new testament
of macroeconomics. Harvard professor Otto Eckstein remarked,
“Harvard lost the most outstanding economist of the generation”
(Sobel 1980, 101).
How Samuelson Came to Write His Famous Textbook:
“A Singular Opportunity”
In the early postwar period, Harvard students studied economics
from outdated textbooks that said nothing about the war and little
about the new economics of Keynes. “Students at Harvard and
MIT often had that glassy-eyed look,” commented Samuelson. His
department head asked him to write a new text. Three years later,
after toiling through nights and summers (“my tennis suffered”),
Economics was born.
Attacked from Both Sides
The first edition, published by McGraw-Hill, sold over 120,000 copies
through 1950 and just kept selling. But it soon came under attack
from the business community, on the one hand, which complained
of its socialistic tendencies, and the Marxists, on the other hand,
who complained of its capitalistic tendencies. William F. Buckley,
Jr., protested in God and Man at Yale (1951) that Samuelson’s textbook
was antibusiness and progovernment. An organization called
the Veritas Foundation published Keynes at Harvard and identified
Keynesianism with Fabian socialism, Marxism, and fascism. On
the other side, Marxists took umbrage at Samuelson’s assertion that
Marx’s predictions about the capitalist system were “dead wrong.”
A massive two-volume critique, Anti-Samuelson (1977), was published
to counter Samuelson and introduce Marxism to students.
Samuelson was pleased to hear that in Stalin’s day, Economics was
kept on a special reserve shelf in the library, along with books on
sex, forbidden to all but specially licensed readers. “Actually,” responded
Samuelson, “when your cheek is smacked from the Right,
the pain may be assuaged in part by a slap from the Left” (1998,
xxvi). Meanwhile, Samuelson offered a seemingly balanced brand of
economics that found mainstream support. While he favored heavy
involvement in “stabilizing” the economy as a whole, he appeared
relatively laissez-faire in the micro sphere, supporting free trade,
competition, and free markets in agriculture.
The High Tide of Keynesian Economics
The success of Keynesian economics and Samuelson’s textbook
reached its zenith in the early 1960s. The MIT professor became
president of the AEA in 1961, the year John F. Kennedy was inaugurated
president. Samuelson, along with Walter Heller and other top
Keynesians, was a close advisor to Kennedy and helped steer through
Congress the Kennedy tax cut of 1964, a Keynesian program designed
to stimulate economic growth through deliberate deficit financing. It
appeared to work, as the economy flourished through the mid-1960s.
By that time, Samuelson’s textbook reigned atop the profession, selling
more than a quarter of a million copies a year. And a year after
the Nobel Prize in economics was established in 1969 by the Bank
of Sweden, the prize went to Paul A. Samuelson.
Samuelson’s textbook has been on the decline since the turbulent
and inflationary 1970s, and today—a half-century after the first
edition—it no longer tops the list in popularity. However, the new
front-runners (especially Campbell McConnell’s textbook, which has
been among the top sellers for years) are mostly considered clones
of Samuelson. Since 1985, new editions of Economics have been
coauthored by Yale professor William D. Nordhaus, and Samuelson’s
hair has turned from blond to brown to gray in his sunset years. Yet
“his memory dazzles even when it fails,” writes an admirer (Elzinga
1992, 878).
Samuelson’s Goal: To Raise the Keynesian Cross Atop a
New House of Economics
What was Paul Samuelson trying to achieve? There is no real
Samuelson school of economics; he considers himself “the last
generalist in economics.” (But what about Kenneth Boulding?)
The MIT professor’s intention was, first and foremost, to introduce
Keynesianism to the classroom: the multiplier, the propensity to
consume, the paradox of thrift, countercyclical fiscal policy, national
income accounting, and C + I + G were all new topics introduced in
the first edition of Economics in 1948. Only John Maynard Keynes
was honored with a biographical sketch in early editions, and only
Keynes, not Adam Smith or Karl Marx, was labeled “a many-sided
genius” (Samuelson 1948, 253).
The “Keynesian cross” income-expenditure diagram, invented by
Samuelson and reproduced in Figure 6.1, was printed on the cover of
the first three editions. The Keynesian cross incorporates all the elements
of the new “general” theory. In the diagram in Figure 6.1, note
that saving (S) increases with national income (NI). As people earn
more, they save more. However, investment (I) is autonomous and
independent of saving. It is set at a fixed amount because, according
to Keynes’s theory, investment is fickle and varies with the “animal
spirits” and expectations of investors and businessmen. So the investment
schedule is set at any level, unrelated to income. Equilibrium
(M) is set at the point where S = I, which you will note falls short
of full-employment income (F). Thus, the Keynesian cross reflects
underemployment equilibrium.
This static equilibrium model represents Samuelson’s (and
Keynes’s) view that capitalism is inherently unstable and can be
stuck indefinitely at less than full employment (M). No “automatic
mechanism” guarantees full employment in the capitalist economy
(Samuelson and Nordhaus 1985, 139). Samuelson compared capitalism
to a car without a steering wheel; it frequently runs off the road
and crashes: “The private economy is not unlike a machine without
an effective steering wheel or governor,” he wrote. “Compensatory
fiscal policy tries to introduce such a governor or thermostatic
control device” (Samuelson 1948, 412). Krugman compares the
market economy to a system that needs a “new alternator” (Krugman
2006).
How the Multiplier Works Magic
How does compensatory fiscal policy work? There are two ways for
the economy to grow and reach full employment under Keynesian
theory: Shift investment schedule I upward, or shift saving schedule
S to the right.
First, let’s look at investment. Schedule I can be shifted upward by
restoring business confidence, primarily through increased government
spending or tax cuts. Both techniques have a multiplier effect—either
a $100 billion spending program or a tax cut can create $400 billion
in new income.
But Samuelson noted that under the Keynesian system, government
spending has a higher multiplier than a tax cut. Why? Because
100 percent of a federal program is spent, while only a portion of a
tax cut is spent—some of it is saved. Samuelson called his discovery
the “balanced budget multiplier.” Thus, a new federal spending
program is preferred over a tax cut by Keynesians because the expenditure
side is considered a more potent weapon against recession
than a tax cut.
The Paradox of Thrift Denies Adam Smith
The second way out of a recession is to increase the public’s propensity
to consume, which would shift saving schedule S to the right.
Note that in the Keynesian model, if the public decides to save
more during an economic downturn, it only makes matters worse.
Consumers buy less, producers lay off workers, and households end up
saving less. An increased supply of savings cannot lower interest rates
and encourage investment under the crude Keynesian model because
interest rates are assumed to be constant. In the Figure 6.1 diagram,
more savings means that the saving schedule S shifts backward to the
left, and has no effect on raising the I schedule.
Samuelson called this phenomenon the “paradox of thrift” (see
Figure 6.2)—an increase in desired thrift results in less total savings!
“Under conditions of unemployment, the attempt to save may result
in less, not more, saving,” he declared (1948, 271). Keynes, of course,
said practically the same thing, only more eloquently: “The more
virtuous we are, the more determinedly thrifty, the more obstinately
orthodox in our national and personal finance, the more our incomes
will have to fall” (Keynes 1973a [1936], 111).

Figure 6.2 Samuelson’s “Paradox of Thrift”

McGraw-Hill.
Samuelson delighted in this attack on the orthodoxy of Adam
Smith and Benjamin Franklin. Smith found thrift a universal virtue,
writing that “What is prudence in the conduct of every private
family, can scarce be folly in that of a great kingdom” (1965
[1776], 424). Franklin counseled every child, “A penny saved is a
penny earned.” But Samuelson labeled this thinking a “fallacy of
composition.” “What is good for each person separately need not
be good for all,” he countered. Moreover, Franklin’s “old virtues
[of thrift] may be modern sins” (1948, 270). As one modern-day
textbook put it, “While savings may pave the road to riches for an
individual, if the nation as a whole decides to save more, the result
could be a recession and poverty for all” (Baumol and Blinder
1988, 192).
The Keynesians readily endorsed savings as a virtue during periods
of full employment, but Samuelson was convinced it seldom
happened. “[F]ull employment and inflationary conditions have occurred
only occasionally in our recent history,” he wrote. “Much of
the time there is some wastage of resources, some unemployment,
some insufficiency of demand, investment, and purchasing power”
(1948, 271). This paragraph remained virtually the same throughout
the first eleven editions of his textbook.1
Savings as Leakage
Echoing Keynes, Samuelson declared war on uninvested savings,
which could “leak” out of the system and “become a social vice”
(1948, 253). He produced a diagram (see Figure 6.3) separating
savings from investment. The diagram shows savings leaking out of
the system, unconnected to the investment hydraulic handle above.
(This diagram led observers to call the model “hydraulic Keynesianism,”
with the emphasis on priming the pump through government
spending.)
Is Consumption More Important Than Saving?
The Keynesian model leads to the odd conclusion that consumption is
more productive than saving. As noted above in the Keynesian cross
model, an increase in the “propensity to consume” (a lower saving rate)
leads to full employment. Keynes applauded “all sorts of policies for
increasing the propensity to consume,” including confiscatory inheritance
taxes and the redistribution of wealth in favor of lower-income
groups, who consume a higher percentage of their income than the
wealthy (1973a [1936], 325). Canadian economist Lorie Tarshis, the
first to write a Keynesian textbook, warned that a high rate of saving
is “one of the main sources of our difficulty,” and one of the goals
of the federal government should be “reducing incentives to thrift”
(Tarshis 1947, 521–12).
Keynesian economist Hyman Minsky confirmed this unorthodox
approach when he said, “The policy emphasis should shift from the
encouragement of growth through investment to the achievement of full
employment through consumption production” (Minsky 1982, 113). Of
course, all of this Keynesian theory goes counter to traditional classical
growth theory that a high level of saving is a key ingredient to economic
growth.

Is Keynesianism Politically Neutral?
Samuelson contended that the Keynesian “theory of income determination”
is politically “neutral.” For example, “it can be used as
well to defend private enterprise as to limit it, as well to attack as to
defend government fiscal interventions” (1948, 253). But the evidence
disputes this claim.
For instance, the balanced-budget multiplier (which Samuelson
considers one of his proudest “scientific discoveries”) favors government
spending programs over tax cuts as a countercyclical policy.
According to Samuelson, progressive taxation (imposing higher tax
rates on the wealthy) has a “favorable” redistributionist effect on the
economy: “To the extent that dollars are taken from frugal wealthy
people rather than from poor ready spenders, progressive taxes tend
to keep purchasing power and jobs at a high level” (1948, 174).
Samuelson also endorsed Social Security taxes, farm aid, unemployment
compensation, and the rest of the welfare state as “built-in
stabilizers” in the economy. The index of Samuelson’s textbook
consistently lists “market failures” (including imperfect competition,
externalities, inequalities of wealth, monopoly power, and public
goods) but not “government failures.” His bias is overwhelmingly
evident.
Apologist for the National Debt
In early editions, Samuelson denied that the national debt was a burden.
The first edition favors the “we owe it to ourselves” argument:
“The interest on an internal debt is paid by Americans to Americans;
there is no direct loss of goods and services” (1948, 427). In the seventh
edition (1967a), after raising the specter of “crowding out” of
private investment, Samuelson went on to say: “On the other hand,
incurring debt when there is no other feasible way to move the C +
I + G equilibrium intersection up toward full employment actually
represents a negative burden on the intermediate future to the degree
that it induces more current capital formation than would otherwise
take place!” (1967a, 346). At the end of an appendix on the national
debt, Samuelson compared federal debt financing to private debt
financing, such as AT&T’s “never-ending” growth in debt (1967a,
358). By implication, he suggested that government debt could also
grow continually, rather than necessarily being balanced over the
business cycle.2
In sum, Keynesian economics as presented by Samuelson became
an apology for big-government capitalism in the postwar period. “A
laissez-faire economy cannot guarantee that there will be exactly the
required amount of investment to insure full employment” (1967a,
197–78). Only a powerful state can.
Critics Begin a Long Battle Against Keynesian Economics
Samuelson claimed in his first edition that the Keynesian system
was “increasingly accepted by economists of all schools of thought”
(1948, 253). Judging from the popularity of Samuelson’s textbook, he
was right. In the 1950s and 1960s, scholars in the major economics
departments spent their entire careers doing empirical studies on the
consumption function, the multiplier, national income statistics, and
other Keynesian aggregates. Keynesian macroeconomics also became
popular among journalists, because it was easy to understand (increasing
consumer spending is “good for the economy”), and among
politicians, because deficit spending bought votes. Robert Solow,
Samuelson’s colleague at MIT and a Nobel laureate, summarized
the new orthodoxy when he proclaimed with considerable pride that
“short-term macroeconomic theory is pretty well in hand. . . . All that
is left is the trivial job of filling in the empty boxes” (1965, 146).
The Pigou Effect: The First Assault
But over time critics have chipped away at the Keynesian structure.
The first objection was the “liquidity trap” doctrine, Keynes’s fear
that the economy could be trapped indefinitely in a deep depression
where interest rates are so low and “liquidity preference” so high that
reducing interest rates further would have no effect (Keynes 1973a
[1936], 207). The man who first countered the liquidity-trap doctrine
was Arthur C. Pigou, ironically the straw man Keynes vilified in The
General Theory. In a series of articles in the 1940s, Pigou said that
Keynes overlooked a beneficial side effect of a deflation in prices and
wages: deflation increases the real value of cash, Treasury securities,
cash-value insurance policies, and other liquid assets of individuals
and business firms. The increased value of these liquid assets raises
aggregate demand and provides the funds to generate new buying
power and hire new workers when the economy bottoms out (Pigou
1943, 1947). This positive real wealth effect, or what Israeli economist
Don Patinkin later named the “real balance effect” in his influential
Money, Interest and Prices (1956), did much to undermine the Keynesian
doctrine of a liquidity trap and unemployed equilibrium.
The Pigou “wealth” or “real balance” effect can also be extended
to the issue of wage cuts during a downturn. Keynes rejected the classical
argument that wage cuts are necessary to adjust the economy to
new equilibrium conditions, from which a solid recovery could occur.
Arguing against the conventional view that persistent unemployment
is caused by excessive wage rates, Keynes claimed that wage
cuts would simply depress demand further and do nothing to reduce
unemployment. But Keynes and his followers confused wage rates
with total payroll. Facing a recession and widespread unemployment,
business leaders recognize that a reduction in wage rates can actually
boost net employment and total payroll. Cutting wages allows firms
to hire more workers at the bottom of a slump. When the economy
bottoms out, well-managed companies begin hiring more workers at
low wages, so that even though the wage rate remains low, the total
payroll increases, and thus puts the economy back on the road to
recovery (Hazlitt 1959, 267–69; Rothbard 1983 [1963], 46–48).
Growth Data Contradict Antithrift Doctrine
Economic historians had serious doubts almost immediately about the
Keynesian antipathy toward saving, which has always been considered
a key ingredient to long-term economic growth. They point especially
to European and Asian countries, such as Germany, Switzerland, Japan,
and Southeast Asia, whose growth rates have benefited tremendously
from high rates of saving during the postwar period. Nobel laureate
Franco Modigliani, as well as top textbook writer Campbell McConnell,
both Keynesians, have recognized the direct relationship between saving
rates and economic growth. For example, the graph in Figure 6.4 was
included in Franco Modigliani’s Nobel Prize paper in 1986.
Historically, the evidence is overwhelming: higher saving rates lead
to higher growth rates–just the opposite of the standard Keynesian
prediction. As one recent Keynesian textbook declared after teaching
students about the paradox of thrift: “The fact that governments do
not discourage saving suggests that the paradox of thrift generally is
not a real-world problem” (Boyes and Melvin 1999, 265).
But then why teach the paradox of thrift at all? Not only is it historically
unproved, but it is fundamentally flawed. The problem is that
Keynesians treat savings as if it disappears from the economy, that
it is simply hoarded or left languishing in bank vaults, uninvested.
In reality, saving is simply another form of spending, not on current
consumption, but on future consumption. The Keynesians stress only
the negative side of saving, the sacrifice of current consumption, while
ignoring the positive side, the investment in productive enterprise.
As noted in chapter 4, the Austrian economist Eugen Böhm-Bawerk
stressed the positive side of saving: “For an economically advanced
nation does not engage in hoarding, but invests its savings. It buys
securities, it deposits its money at interest in savings banks or commercial
banks, puts it out on loan, etc.” (1959 [1884], 113).
Saving Has a Multiplier, Too!
Saving is in fact a better form of spending because it offers a potentially
infinite payoff in future productivity (thus Franklin’s refrain, “A
penny saved is a penny earned”). If the public saves more generally,
the pool of savings enlarges, interest rates decline, old equipment is
replaced, and more research and development, new technology, and
new production processes evolve. The future benefits are incalculable.
Meanwhile, funds spent on pure consumer goods are used up within
a certain period, or depreciated over time.
The Keynesian multiplier (k) is higher as the public consumes more.
But proponents assume that the savings remain uninvested—a false
assumption under normal conditions. In truth, both components of
income—consumption and savings—are spent. Thus, the multiplier
(k) is infinite! The saving component also has a multiplier effect in
the economy as it is invested in the intermediate production stages.
Moreover, the savings k is theoretically more productive than the
consumption k because it is not used up as fast.
Going back to Samuelson’s hydraulic model (Figure 6.2), saving
does not leak out of the system, but goes back into the system to
improve the factors of production (land, labor, and capital) through
new technology, education, and training. Figure 6.5 demonstrates how
saving, consumption, and the economy really operate.
The Ekins diagram in Figure 6.5 is what Samuelson should have
published over the years in his textbook instead of the hydraulic model.
In this chart, the ultimate purpose of economic activity is to provide
increasing utility. Note how in the diagram, consumption is used up.
It is consumption—not saving—that “leaks” out and is consumed as
utility. Saving, on the other hand, is invested back into the economic
process over and over again, facilitating new investment and improving
our standard of living (utility/welfare). An amazing contrast.
A Critical Flaw in the Keynesian Model
The central problem with the Keynesian model is that it fails to
comprehend the true nature of the production-consumption process.
The Keynesian system assumes that the only thing that matters is
current demand for final consumer goods—the higher the consumer
demand, the better. Despite talk that Keynes is dead, this Keynesian
preoccupation with consumer demand is almost universally accepted
in the establishment media today. For example, Wall Street monitors
retail sales figures to determine the direction of the economy and
the markets. They seem to be disappointed if consumers don’t spend
enough—as if they want the Christmas season to last all year!
Yet is consumer spending the cause or the effect of prosperity? If
everyone went on a buying spree at the local department store or grocery
store, would investment in new products and technology expand?
Certainly investment in consumer goods would expand, but increased
expenditures for consumer goods would do little or nothing to construct
a bridge, build a hospital, pay for a research program to cure cancer, or
provide funds for a new invention or a new production process.
According to business-cycle analysts, retail sales and other measures
of current consumer spending are lagging indicators of economic activity.
Almost all of the components of the U.S. Commerce Department’s
Index of Leading Economic Indicators are production and investment
oriented, for example, contracts and orders for plant equipment, changes
in manufacturing and trade inventories, changes in raw material prices,
and the stock market, which represents long-term capital investment
(Skousen 1990, 307–12). Typically in a business cycle, consumption
starts declining after the recession has already started; similarly, consumer
spending picks up after the economy begins its recovery stage.
This myth of a consumer-driven economy persists in part because
of a misunderstanding of national income accounting. The media frequently
report that consumer spending accounts for two-thirds of GDP.
Recall that GDP = C + I + G, and typically in the United States:
C = 70 percent
I = 12 percent
G = 18 percent
Therefore, the media conclude that, since consumption accounts for approximately
two-thirds of GDP, the economy must be consumer-driven.
Not so. GDP is defined as the value of all final goods and services
produced in a year. It ignores all intermediate production in the
economy at the wholesale, manufacturing, and natural-resource stages.
If one measures spending at all levels of production, the results are
surprisingly different.
I have created a national income statistic called gross domestic
expenditures (GDE), which measures gross sales at all stages of production.
3 Using this new, broader definition of total spending in the
economy, it becomes apparent that consumption represents only about
one-third of economic activity, and that business spending (investment
plus goods-in-process spending) accounts for more than half of
the economy. Thus, business investment is far more important than
consumer spending in the United States (and in most other nations).
The Keynesian macroeconomic model suffers from the defect of
oversimplification—it assumes only two stages, consumption and investment,
and it assumes that investment is a direct function of current
consumption only. If current consumption increases, so will investment,
and vice versa.
How the Economy Really Works
William Foster and Waddill Catchings committed this same error.
As Hayek pointed out in his critique of the Foster-Catchings debate,
investment is actually multistaged and changes form and structure
when interest rates rise or fall. Investment is not simply a function of
current demand, but of future demand; both long-term and short-term
interest rates influence investment and capital formation (Hayek 1939
[1929]). For example, suppose the public decides to save more of their
income for a better future. Spending for cars, clothing, entertainment,
and other forms of current consumption might level off or even fall. But
this temporary slowdown in consumption does not cause a broad-based
recession. Instead, the increased savings leads to lower interest rates,
which encourage businesses, especially in capital-goods industries and
research and development, to expand operations. Lower interest rates
mean lower costs. Businesses can now afford to upgrade computers
and office equipment, construct new plants and buildings, and expand
inventories. Lower interest rates can even reverse the slowdown in car
sales by offering cheaper financing to prospective car buyers. Contrary
to the dire predictions of the Keynesians, an increase in the propensity
to save pays for itself. It does not lead to a “recession and poverty for
all” (Baumol and Blinder 1988, 192). Only the structure of production
and consumption changes, not the total amount of economic activity.
An Example: Building a Bridge
A hypothetical example could be useful in reinforcing the benefits of
increased savings. Suppose St. Paul and Minneapolis are separated
by a river and that the only transportation between the two cities is
by barge. Travel between the twin cities is expensive and time-consuming.
Finally, the city fathers call a meeting and decide to build
a bridge. Everyone agrees to cut back on current spending and put
their savings to work to build the bridge. In the short run, retail sales,
employment, and profits in local department stores decline. Yet new
workers and new investment funds are assigned to the building of the
bridge. In the aggregate, there is no reduction in output and employment.
Moreover, once the bridge is completed, the twin cities benefit
immensely from lower travel costs and increased competition between
St. Paul and Minneapolis. In the end, the twin cities’ sacrifice has been
transformed into a higher standard of living.
Say’s Law Redux: Production Is More Important
Than Consumption
In essence, the Keynesian demand-driven view of the economy
fails to recognize another force that is even stronger than current
demand—the demand for future consumption. Spending money on
current consumer goods and services will do nothing to change the
quality and variety of goods and services of the future. Such change
requires new savings and investment.
Thus, we return to the truism of Say’s law: Supply (production)
is more important than demand (consumption). Consumption is the
effect, not the cause, of prosperity. Production, saving, and capital
formation are the true cause.
