Keynesian economics are the various macroeconomic theories and models of how aggregate demand strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. Instead, it is influenced by a host of factors – sometimes behaving erratically – affecting production, employment, and inflation.
John Maynard Keynes, 1st Baron Keynes, was an English economist, whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, his ideas are the basis for the school of thought known as Keynesian economics, and its various offshoots.
Piero Sraffa was an influential Italian economist who served as lecturer of economics at the University of Cambridge. His book Production of Commodities by Means of Commodities is taken as founding the neo-Ricardian school of economics.
Classical economics or classical political economy is a school of thought in economics that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange.
In economics, effective demand (ED) in a market is the demand for a product or service which occurs when purchasers are constrained in a different market. It contrasts with notional demand, which is the demand that occurs when purchasers are not constrained in any other market. In the aggregated market for goods in general, demand, notional or effective, is referred to as aggregate demand. The concept of effective supply parallels the concept of effective demand. The concept of effective demand or supply becomes relevant when markets do not continuously maintain equilibrium prices.
A liquidity trap is a situation, described in Keynesian economics, in which, "after the rate of interest has fallen to a certain level, liquidity preference may become virtually absolute in the sense that almost everyone prefers holding cash rather than holding a debt which yields so low a rate of interest."
Jan A. Kregel is an eminent post-Keynesian economist.
Alfred S. Eichner was an American post-Keynesian economist who challenged the neoclassical price mechanism and asserted that prices are not set through supply and demand but rather through mark-up pricing.
Michał Kalecki was a Polish Marxian economist. Over the course of his life, Kalecki worked at the London School of Economics, University of Cambridge, University of Oxford and Warsaw School of Economics and was an economic advisor to the governments of Poland, France, Cuba, Israel, Mexico and India. He also served as the deputy director of the United Nations Economic Department in New York City.
The neoclassical synthesis (NCS), neoclassical–Keynesian synthesis, or just neo-Keynesianism was a post-World War II academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes with neoclassical economics. Being Keynesian in the short run and neoclassical in the long run, neoclassical synthesis allowed the economy to adjust via fiscal and monetary policies in the short run whilst predicting that equilibrium in the long run will be reached without state intervention. The synthesis, formulated by a group of economists, dominated economics in the post-war period and formed the mainstream of macroeconomic thought in the 1950s, 1960s and 1970s.
Paul Davidson is an American macroeconomist who has been one of the leading spokesmen of the American branch of the post-Keynesian school in economics. He is a prolific writer and has actively intervened in important debates on economic policy from a position that is very critical of mainstream economics.
Luigi L. Pasinetti is an Italian economist of the post-Keynesian school. Pasinetti is considered the heir of the "Cambridge Keynesians" and a student of Piero Sraffa and Richard Kahn. Along with them, as well as Joan Robinson, he was one of the prominent members on the "Cambridge, UK" side of the Cambridge capital controversy. His contributions to economics include developing the analytical foundations of neo-Ricardian economics, including the theory of value and distribution, as well as work in the line of Kaldorian theory of growth and income distribution. He has also developed the theory of structural change and economic growth, structural economic dynamics and uneven sectoral development.
The Keynesian Revolution was a fundamental reworking of economic theory concerning the factors determining employment levels in the overall economy. The revolution was set against the then orthodox economic framework, namely neoclassical economics.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
Athanasios "Tom" Asimakopulos was a Canadian economist, who was the "William Dow Professor of Political Economy" in the Department of Economics, McGill University, Montreal, Quebec, Canada. His monograph, Keynes's General Theory and Accumulation, reviews important areas of Keynes's General Theory and the theories of accumulation of two of his most distinguished followers, Roy Harrod and Joan Robinson.
Thomas Palley is an American economist who has served as the chief economist for the US–China Economic and Security Review Commission. He is currently Schwartz Economic Growth Fellow at the New America Foundation.
Victoria Chick is a Post Keynesian economist who is best known for her contributions to the understanding of Keynes's General Theory and to the establishment of Post Keynesian economics in the UK and elsewhere.
Larry Randall Wray is a professor of Economics at Bard College and Senior Scholar at the Levy Economics Institute. Previously, he was a professor at the University of Missouri–Kansas City in Kansas City, Missouri, USA, whose faculty he joined in August 1999, and a professor at the University of Denver, where he served from 1987 to 1999. He has served as a visiting professor at the University of Rome, Italy, the University of Paris, France, and the UNAM, in Mexico City. From 1994 to 1995 he was a Fulbright Scholar at the University of Bologna. From 2015 he is a Visiting professor at the University of Bergamo.
Marxism and Keynesianism is a method of understanding and comparing the works of influential economists John Maynard Keynes and Karl Marx. Both men's works has fostered respective schools of economic thought that have had significant influence in various academic circles as well as in influencing government policy of various states. Keynes' work found popularity in developed liberal economies following the Great Depression and World War II, most notably Franklin D. Roosevelt's New Deal in the United States in which strong industrial production was backed by strong unions and government support. Marx's work, with varying degrees of faithfulness, led the way to a number of socialist states, notably the Soviet Union and the People's Republic of China. The immense influence of both Marxian and Keynesian schools has led to numerous comparisons of the work of both economists along with synthesis of both schools.
