John Maynard Keynes

Historical

Jun 5, 1883

Apr 21, 1946

John Maynard Keynes, who was born in Cambridge, England, was one of the leading economists of the twentieth century. His lasting ideas influenced macroeconomics and governmental economic policies across the globe. Keynes was a professional mathematician, and having borrowed from earlier theories, he contributed to developing a much more defined theory regarding business cycles. His early work or the works that have set the tone for his ideas include The General Theory of Employment, Interest, and Money (1936). Keynes's early academic life featured education at King's College, Cambridge, where he was exposed to economics by Alfred Marshall and Arthur Pigou. His ability in mathematics and passion for philosophy provided a good background for his future contributions to economics. After graduating in 1905, Keynes jumped from university to government jobs to get a practical feel for economic policymaking. One of the significant milestones in Keynes's career was after the First World War when he played an essential role as an economic adviser to the British delegation during the negotiation of the Treaty of Versailles. He also grew disappointed with the actions taken against Germany, and in his book The Economic Consequences of the Peace (1919), he foresaw long-term political and economic unrest. Many people consider this treaty to have been unbalanced, and his scathing critique helped him become widely known and a prominent economist. During the Great Depression of the 1930s, Keynes introduced new approaches to dealing with worldwide economic emergencies. New classical economics, which mainly preached non-interventionist policies, could not account for the stagnation. Keynes, however, maintained that the total demand by consumers, businesses, and the government was essential to economic activity. He supported higher government spending to stimulate demand and lower the unemployment rate during recessions. Keynesianism was adopted as the economic policies of fiscal and monetary interventions were widely used during and after the Second World War. His ideas contributed to the formation of the International Monetary Fund (IMF) and World Bank, which were pivotal in controlling post-war trade and economic policies. Though Keynes attracted criticism, especially from monetarists such as Milton Friedman, in the 1970s, his influence rose again after the financial crisis of 2007-2008. His theories on government intervention were brought back to the limelight as governments sought ways to avoid an economic disaster. In this way, Keynes's influence is not only in the details of macroeconomic theory but also in the creation of contemporary economics and the formation of policymaking practices.

Life and achievements

Early life

John Maynard Keynes was born in 1883 in Cambridge, England, to a very affluent family. His father, John Neville Keynes, was an economist and a lecturer at the University of Cambridge, while his mother, Florence Ada Keynes, was a social reformer. He was raised intellectually, and his parents influenced his education. John Maynard Keynes, an influential economist of the 20th century, was educated at Eton College and King's College, Cambridge, where he majored in mathematics. When Keynes was at Cambridge, he was under the tutelage of Alfred Marshall, an essential economist of that age, and Arthur Pigou. However, he also became quite interested in philosophy, especially the philosophical works of G. E. Moore. Education and intellectual surroundings contributed to the development of his analytical mind and provided the basis for his future work in economics. Keynes began his career in the civil service after he got his degree in 1905. He worked at the India Office in London but got bored with bureaucratic work and returned to Cambridge to lecture and indulge in his academic aspirations. His first economics article was about Indian currency and was published in finance in 1913.

Legacy

There is no doubt that Keynes left a great impact on economic theory and policymaking worldwide. His theory of economic intervention revolutionized economic policies globally, especially after the Great Depression and World War II. His theories led to the formation of Keynesian economics, which is still the central economic theory in practice, although it faced competition from monetarist and neoclassical theories. It is necessary to note that Keynes's impact was not limited to academia. He played a significant role during the Bretton Woods Conference, which resulted in the creation of the IMF and World Bank in the post-war world. They are still important players in the governance of the world economy. The Keynesian policies were most popular after World War II and played a significant role in economic growth and low unemployment in Europe and America. However, his impact was less felt in the 1970s due to the emergence of neoliberalism, but his theories were relevant during the 2008 financial crisis. The Keynesian approaches were revived in global policy circles, particularly the idea of government expenditure to pull struggling economies out of the cycle, thus immortalizing Keynes's contribution.
