John Maynard Keynes

1883–1946

Keynes, who saw capital

But those who own capital receive interest simply because capital is scarce.

Overview

John Maynard Keynes was an economist born in Cambridge, England, in 1883. Record

In 1919 he went to the Paris Peace Conference as the British Treasury's representative, resigned in opposition to the terms of German reparations, and wrote The Economic Consequences of the Peace. Record

In 1936 he published The General Theory of Employment, Interest and Money. The Concise Encyclopedia of Economics (Econlib) judges that the book popularized the idea of demand for the economy as a whole (aggregate demand) and showed (or claimed to show) that government spending is needed to maintain full employment. Interpretation · Econlib, The Concise Encyclopedia of Economics

From 1924 until his death he was First Bursar of King's College and managed the college's investments. In his personal investing he suffered heavy losses around 1920 and 1929 and then built up his wealth again. Record

At the Bretton Woods conference in 1944 he was one of the leading figures in creating the post-war international monetary system, including the International Monetary Fund (IMF). Record

  3. 1902–1905

    As a student he mixed with the philosopher G. E. Moore in the Cambridge discussion society, the 'Apostles', and was deeply drawn to Moore's Principia Ethica (1903). Later (in a 1938 memoir) he recalled that the book's ideas about the good were for a time their 'religion', adding that they set aside Moore's rules of conduct (morals). Record

    During the First World War he worked at the Treasury, and he went to the Paris Peace Conference as the Treasury's representative. Judging the terms of German reparations unjust and unworkable, he resigned in June. In December he published The Economic Consequences of the Peace. The book became a bestseller, selling more than 100,000 copies worldwide by August 1920. Its judgments have since met counter-arguments as well. Record

Key ideas

In the long run we are all dead

While granting that the quantity theory of money might be true 'in the long run', he said that the long run is a misleading guide to current affairs. He wrote that economists who in a storm can only say that 'when the storm is long past the ocean is flat again' set themselves too easy and too useless a task. Record · Paraphrase

In a hundred years the economic problem may be solved

He wrote that, barring great wars and large increases in population, the economic problem might be solved, or at least within sight of solution, within a hundred years. Then the remaining work might be shared out so that people work about three hours a day, around fifteen hours a week, and the real problem would become how to use the spare time to live wisely, agreeably and well.

Interest is paid because capital is scarce

He wrote that just as a landowner receives rent because land is scarce, the owner of capital receives interest because capital is scarce. Interest today, he said, rewards no genuine sacrifice, and he foresaw that once capital became plentiful, the share of those who live on interest without working (the rentier) would disappear.

Full employment does not come by itself

He named as the outstanding faults of the economic society he lived in its failure to provide full employment and its arbitrary and inequitable distribution of wealth and incomes. The Concise Encyclopedia of Economics (Econlib) judges that the General Theory introduced the idea of aggregate demand — consumption, investment and government spending added together — and showed (or claimed to show) that government spending is needed to maintain full employment. Interpretation · Econlib, The Concise Encyclopedia of Economics

Probability as a logical relation between evidence and conclusion

In A Treatise on Probability (1921) he treated probability as a logical relation expressing how far some evidence supports a hypothesis. Scholars count him as a leading defender of the 'logical' interpretation of probability. Interpretation · SEP (Alan Hájek)

In their words

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.

Times and influence

Europe in the first half of the twentieth century, when Keynes was active, went through two world wars. After the First World War the Treaty of Versailles imposed heavy reparations on Germany, and in 1929 came the Wall Street Crash.

At the 1944 Bretton Woods conference, in which he took a leading part, the agreement founding the International Monetary Fund (IMF) was concluded, and the IMF formally came into being in December 1945. Scholars regard the General Theory as the book that popularized the idea of aggregate demand. The investment record of the King's College funds he managed is still used as material in research on institutional investing.
