KALECKI, MICHAL (1899–1970), Polish economist. Born in Lodz and educated at Cambridge and Oxford, Kalecki worked for the United Nations Economic Department from 1947 to 1954. In 1957 he joined the Polish State Planning Commission where he was instrumental in preparing Poland's first 20-Year Plan (1959). He taught in Warsaw from 1961 to 1968 when, under pressure exerted by the Polish authorities, he resigned and ceased teaching. His studies on business cycles, inspired by Karl *Marx and Rosa *Luxemburg, anticipated much of Keynes' General Theory of Employment, Interest and Money (1936), and his work on war economics and full employment ensured him an eminent place, particularly among English-speaking economists. He was a member of the Polish Academy of Sciences. Outstanding among his more than 200 publications are Essays in the Theory of Economic Fluctuations (1939); Studies in Economic Dynamics (1943); Theory of Economic Dynamics (1954, 19652); and Zarys teorii wzrostu gospodarki socjalistycznej ("Outline of the Theory of Development in a Socialist Economy", 1963).
Problems of Economic Dynamics and Planning (1966).
