Biography

Wassily Leontief's name has been associated with a particular type of quantitative economics: input-output analysis. Input-output was partly inspired by the Marxian and Walrasian analysis of general equilibrium via interindustry flows - which in turn were inspired by Francois Quesnay's Tableau Economique, and was the outgrowth of the 'multi-sectoral' approach followed by the Kiel School. Although of fluctuating popularity, input-output analysis has been a mainstay of economics and economic policy and planning throughout the world for the past half-century.

Raised in Russia, Leontief obtained his Ph.D. in Berlin. Although the seeds of input-output analysis were already in his work at the Kiel Institute, he would have to wait until he reached Harvard in 1932 to begin constructing an empirical example of his input-output system - an effort which gave rise to his 1941 classic, Structure of American Industry. Leontief followed up this work with a series of classical papers on input-output economics (collected in 1966). Input-output was novel and inspired large-scale empirical work. It has been used for economic planning throughout the world, whether in Western, Socialist or Third World countries.

It was also of crucial theoretical importance. Input-output inspired the analysis of linear production systems, which were instrumental in the development of modern Neo-Walrasian theory. Unusual for most economic contributions, Leontief's system was also crucial for the revival of Classical Ricardian theory. The structure of input-output (albeit with some critical differences) was employed by Piero Sraffa and the Neo-Ricardians in the 1960s to resurrect the theories of David Ricardo and Karl Marx.

Leontief's contributions to economics were not limited to input-output. His 1936 article on composite commodities made him, together with John Hicks, the father of that famous microeconomic theorem. His early reviews of Keynes's General Theory (1936, 1937, 1947, 1948) were important stepping stones to the Neo-Keynesian synthesis's stress on fixed nominal wages in interpreting Keynes's theory. His 1933 article on the analysis of international trade is still learnt today and his 1946 contribution on the wage contract outlined what is now a classical application of the principal-agent model before that term was invented. One of his more stirring contributions has been his 1953 finding that Americans were exporting labor-intensive rather than capital- intensive goods - the Leontief Paradox - which brought into question the validity of the conventional factor-proportions theory of international trade.

After having presided, together with Joseph Schumpeter, as a teacher over the Harvard generation of the 1930s which was to develop much of post-war economics, Leontief moved to the C.V. Starr Center at New York University. As a critic, Leontief's repeated admonishment of economics for its misuse of mathematics and quantitative methods and the lack of relevance and realism in its theorizing (e.g. 1938, 1954, 1959, 1971) are both lucid, sharp and still pertinent.

It was for his development of input-output that Wassily Leontief won the Nobel memorial prize in 1973.
