Tjalling Koopmans

Tjalling Charles Koopmans (August 28, 1910–February 26, 1985) was the joint winner, with Leonid Kantorovich, of the 1975 Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel.

His contributions

• Koopmans was awarded his 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.
• His early works on the Hartree-Fock theory are associated to the Koopmans' theorem which is very well known in quantum chemistry.
