Michał Kalecki

Michał Kalecki ( Polish: [ˈmixaw kaˈlɛt͡skʲi]; 22 June 1899 – 18 April 1970) 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.

Kalecki has been called "one of the most distinguished economists of the 20th century" and "likely the most original one". It is often claimed that he developed many of the same ideas as John Maynard Keynes before Keynes but remains much less known to the English-speaking world. He offered a synthesis that integrated class analysis of Marxism and the new literature on oligopoly theory, and his work had a significant influence on both the neo-Marxian (Monopoly Capital) and post-Keynesian schools of economic thought. He was one of the first macroeconomists to apply mathematical models and statistical data to economic questions. Being also a political economist and a person of left-wing convictions, Kalecki emphasized the social aspects and consequences of economic policies.
