"John Maynard Keynes | Biography, Theory, Economics, Books, & Facts

John Maynard Keynes, (born June 5, 1883, Cambridge, Cambridgeshire, England—died April 21, 1946, Firle, Sussex), English economist, journalist, and financier, best known for his economic theories (Keynesian economics) on the causes of prolonged unemployment. His most important work, The General Theory of Employment, Interest and Money (1935–36), advocated a remedy for economic recession based on a government-sponsored policy of full employment.

Background and early career
Keynes was born into a moderately prosperous family. His father, John Neville Keynes, was an economist and later an academic administrator at the King’s College, Cambridge. His mother was one of the first female graduates of the same university, which Keynes entered in 1902.

At Cambridge he was influenced by economist Alfred Marshall, who prompted Keynes to shift his academic interests from mathematics and the classics to politics and economics. Cambridge also introduced Keynes to an important group of writers and artists. The early history of the Bloomsbury group—an exclusive circle of the cultural elect, which counted among its members Leonard and Virginia Woolf, the painter Duncan Grant, and the art critic Clive Bell—centred upon Cambridge and the remarkable figure of Lytton Strachey. Strachey, who had entered Cambridge two years before Keynes, inducted the younger man into the exclusive private club known simply as “the Society.” Its members and associates (some of them homosexual, like Keynes himself) were the leading spirits of Bloomsbury. Throughout his life Keynes was to cherish the affection and respond to the influence of this group.

After earning a B.A. in 1905 and an M.A. in 1909, Keynes became a civil servant, taking a job with the India Office in Whitehall. His experience there formed the basis of his first major work, Indian Currency and Finance (1913), a definitive examination of pre-World War I Indian finance and currency. He then returned to Cambridge, where he taught economics until 1915. With the onset of World War I, Keynes returned to government employment, this time in the Treasury (an agency even more powerful than its American counterpart), where he studied relations with allies and recommended means of conserving Britain’s scant supply of foreign currencies.

His performance may have marked Keynes for a public career, but the Versailles Peace Conference changed his aspirations. Accompanying Prime Minister David Lloyd George to France as an economic adviser, Keynes was troubled by the political chicanery and burdensome policies that were to be imposed upon the defeated Germany. He resigned his post, depressed, to quote from a letter to his father, by the impending “devastation of Europe.”

He took an activist’s stance, however, by transforming personal distress into public protest. In two summer months he composed the indictment of the Versailles settlement that reached the bookstores by Christmas 1919 as The Economic Consequences of the Peace. The permanent importance of this polemical essay lies in its economic analysis of the stringent reparations placed upon Germany and the corresponding lack of probability that the debts would ever be paid. The popular success of the book, however, came from the blistering sketches of Woodrow Wilson, Georges Clemenceau, and Keynes’s old chief, Lloyd George. As a consequence, in some Whitehall circles Keynes was considered a man not quite to be trusted, an iconoclast willing to rock any boat into which he had imprudently been invited.

Key contributions
Keynes’s reputation at Cambridge was quite different. He was esteemed as the most brilliant student of Marshall and fellow economist A.C. Pigou, authors of large, definitive works explaining how competitive markets functioned, how businesses operated, and how individuals spent their incomes. After publication of The Economic Consequences of the Peace, Keynes resigned his lecture post but stayed on as a fellow of King’s College, dividing his time between Cambridge and London.

Although the tone of Keynes’s major writings in the 1920s was occasionally skeptical, he did not directly challenge the conventional wisdom of the period that favoured laissez-faire—only slightly tempered by public policy—as the best of all possible social arrangements. Two of Keynes’s opinions did foreshadow the theoretical revolution he triggered in the 1930s. In 1925 he opposed Britain’s return to the gold standard at the prewar dollar–pound ratio of $4.86; and, long before the Great Depression, Keynes expressed concern over the persistent unemployment of British coal miners, shipyard workers, and textile labourers. Reconciled by this time with Lloyd George (who was never to return to office), he supported the Liberal Party’s program of public works to take the unemployed off welfare by placing them in useful jobs. But “respectable” economists still expected the automatic adjustments of the free market to solve these problems, and the Treasury was convinced that public works were useless because any increase in the government deficit would likely cause an equal decline in private investment. Although Keynes could not offer a theoretical refutation of his colleagues’ opinions, he agitated for public works nevertheless.

It was only later, in The General Theory of Employment, Interest and Money, that Keynes provided an economic basis for government jobs programs as a solution to high unemployment. The General Theory, as it has come to be called, is one of the most influential economics books in history, yet its lack of clarity still causes economists to debate “what Keynes was really saying.” He appeared to suggest that a reduction in wage rates would not reduce unemployment; instead, the key to reducing unemployment was to increase government spending and to run a budget deficit. Governments, many of them looking for excuses to increase spending, wholeheartedly accepted Keynes’s views. Most of his professional colleagues also accepted his views.

Interestingly, Keynes believed that the kinds of policies he advocated would work best in a totalitarian society. In his preface to the German edition of General Theory, Keynes wrote:

Nevertheless the theory of output as a whole, which is what the following book purports to provide, is much more easily adapted to the conditions of a totalitarian state, than is the theory of production and distribution of a given output produced under conditions of free competition and a large measure of laissez-faire.

Later works and assessment
Keynes’s long-run influence has not been as significant as his short-run impact. The Keynesian model was a core part of economics textbooks from the late 1940s until the late 1980s. But as economists have become more concerned about economic growth, and more informed about inflation and unemployment, the Keynesian model has lost prominence.

The General Theory was Keynes’s last major written work. In 1937 he suffered a severe heart attack. Two years later, though not completely recovered, he returned to teaching at Cambridge, wrote three influential articles on war finance entitled How to Pay for the War (1940; later reprinted as Collected Writings, vol. 9, 1972), and served once more in the Treasury as an all-purpose adviser. He also played a prominent role at the Bretton Woods Conference in 1944. But the institutions that resulted from that conference, the International Monetary Fund and the World Bank, were more representative of the theories of the United States Treasury than of Keynes’s thinking.

His last major public service was his negotiation in the autumn and early winter of 1945 of a multibillion-dollar loan granted by the United States to Britain. Keynes died the following year."
