Cowles Commission

The Cowles Commission was an economics research institution that advanced mathematical economics and econometric methods, especially through its work at the University of Chicago from 1939 to 1955.

Alfred Cowles: An American economist and investor who founded the Cowles Commission for Research in Economics. His funding and founding vision established the institution in 1932.
Econometrics: The application of statistical methods to economic data and theories. The Commission’s institutional mission centered on making economic claims empirically testable.
Econometric Society: An international scholarly society founded in 1930 to advance economic theory and quantitative methods. The Commission grew from the quantitative economics community organized around this society.
Paul Samuelson: An American economist who formalized major areas of economic theory and won the 1970 Nobel Prize. His work helped establish mathematical economics alongside the Commission’s econometric program.
Jacob Marschak: A Ukrainian-American economist who directed the Cowles Commission and advanced decision theory and econometrics. As director from 1943, he guided the Commission’s research program.
Simultaneous equations model: A system of equations in which multiple variables are jointly determined. Commission researchers modeled markets as interdependent systems rather than isolated equations.
University of Chicago: A private research university in Chicago, Illinois, founded in 1890. The Commission was based there from 1939 until its move to Yale.
Mathematical economics: The use of mathematical language and methods to formulate and analyze economic theories. The Commission helped make rigorous mathematical modeling central to economics.
Tjalling Koopmans: A Dutch-American economist whose work on activity analysis and econometrics earned him the 1975 Nobel Prize. His leadership helped define the Commission’s postwar mathematical economics.
Identification problem: The problem of determining whether model parameters can be uniquely inferred from observed data. The Commission clarified when structural economic relationships could be recovered from data.
