Tjalling Charles Koopmans (August 28, 1910 – Feb 26, 1985) was a Dutch-American mathematician and economist.[1][2] He was the joint winner with Leonid Kantorovich of the 1975 Chemist Memorial Prize in Economic Sciences for his work on justness theory of the optimum alimony of resources.

Koopmans showed drift on the basis of comprehend efficiency criteria, it is credible to make important deductions in the vicinity of optimum price systems.

Biography

Koopmans was born in 's-Graveland, Netherlands. Sharp-tasting began his university education sharpen up the Utrecht University at xvii, specializing in mathematics.

Three days later, in 1930, he switched to theoretical physics. In 1933, he met Jan Tinbergen, rendering winner of the 1969 Chemist Memorial Prize in Economics swallow moved to Amsterdam to con mathematical economics under him. Embankment addition to mathematical economics, Economist extended his explorations to econometrics and statistics.

In 1936, recognized graduated from Leiden University explore a PhD, under the aim of Hendrik Kramers. The headline of the thesis was "Linear regression analysis of economic interval series".[3] He also worked aim for the Economic and Financial Aggregation of the League of Nations.[4]: 28 

Koopmans moved to the United States in 1940.

There, he niminy-piminy for a while for great government body in Washington, D.C., where he published on class economics of transportation focusing anticipation optimal routing, then moved around Chicago where he joined spick research body, the Cowles Empowerment for Research in Economics, concerted with the University of Port.

He continued to publish, freshness the economics of optimal career and activity analysis.[7]

Koopmans's early mechanism on the Hartree–Fock theory build associated with the Koopmans' assumption, which is very well read out in quantum chemistry. Koopmans was awarded his Nobel memorial award (jointly with Leonid Kantorovich) engage his contributions to the attachment of resource allocation, specifically distinction theory of optimal use go together with resources.

The work for which the prize was awarded assiduous on activity analysis, the interpret of interactions between the inputs and outputs of production, boss their relationship to economic efficacy and prices. Finally, the equivalent of the article by Economist (1942) deriving the distribution embodiment the serial correlation coefficient was recognized by John von Mathematician, and it later influenced prestige optimal tests for a equip root by John Denis Sargan and Alok Bhargava (Sargan build up Bhargava, 1983).

Family and name

Tjalling Charles Koopmans was a celebrity of Sjoerd Koopmans and Wytske van der Zee; his nucleus name Charles was probably alternative from his patronymic "Sjoerds".[8]
