28, 1910 – February 26, 1985) was a Dutch

American mathematician and economist. He was the joint winner

with Leonid Kantorovich of the 1975 Nobel Memorial Prize in Economic Sciences for his work on

the theory of the optimum allocation of resources. Koopmans showed that on the

basis of certain efficiency criteria, it is possible to make important

deductions concerning optimum price systems. Koopmans was born began his university education at the Utrecht

University at seventeen, specializing in mathematics. Three

years later, in 1930, he switched to theoretical physics. In 1933, he met Jan

Tinbergen, the winner of the 1969 Nobel Memorial Prize in Economics,

and moved to Amsterdam to study mathematical economics under him. In addition to

mathematical economics, Koopmans extended his explorations 1936 he graduated from Leiden

University with a PhD, under the direction of Hendrik

Kramers. The title of the thesis was "Linear regression

analysis of economic time series". Koopmans

moved to the United States in 1940. There he worked for a while for a

government body in Washington D.C., where he published on the economics of transportation focusing on optimal routing,

then moved to Chicago where he joined a research body, the Cowles

Commission for Research in Economics, affiliated with the University of Chicago. In 1946, he became a naturalized citizen of the United

States and in 1948 director of the Cowles Commission. Also in

1948, he was elected as a Fellow of the American Statistical Association.[2] In 1950 he became a corresponding member of

the Royal Netherlands Academy of Arts and Sciences.[3] Rising hostile opposition to the Cowles

Commission by the department of economics at University of Chicago during the

1950s led Koopmans to convince the Cowles family to move it to Yale

University in 1955 (where it was renamed the Cowles

Foundation). He continued to publish, on the economics of

optimal growth and activity analysis. Koopmans' early works on the Hartree–Fock theory are associated with the Koopmans' theorem, which is very well known in quantum

chemistry. Koopmans was awarded his Nobel memorial prize (jointly

with Leonid Kantorovich) for his contributions to the field of resource

allocation, specifically the theory of optimal use of resources. The work for

which the prize was awarded focused on activity analysis, the study of

interactions between the inputs and outputs of production, and their relationship to economic efficiency and prices.

Finally, the importance of the article by Koopmans (1942) deriving the

distribution of the serial correlation coefficient was recognized by John von

Neumann, and it later influenced the optimal tests for a unit root by John and Bhargava, 1983).
