Tjalling Koopmans

Tjalling Koopmans foi um economista notabilizado pelas suas contribuições para a teoria da alocação ótima de recursos.

Tjalling Koopmans (1910-1986)

Tjalling Charles Koopmans nasceu em Gravelines, Holanda em 1910. No início da Segunda Guerra Mundial, ele emigrou para os Estados Unidos, onde ele foi naturalizado. Ele ganhou o Prémio Nobel de Economia em 1975, partilhado com o economista soviético Leonid Kantorovich Vitaliyevich pelas suas contribuições para a teoria da alocação ótima de recursos.

Tjalling Koopmans estudou física e matemática na Universidade de Utrecht e obteve um doutoramento em estatística e economia na Universidade de Leiden. Foi consultor financeiro para a Liga das Nações em Genebra (1938-1940). Ele ensinou nas Universidades de Chicago (1946-1955) e Yale. Diretor da Comissão de Cowles (1944-1954) e membro da Fundação Cowles em Yale (1961-1967).
