Karl William Kapp

Karl William Kapp (October 27, 1910 – April 4, 1976) was a German-American economist and professor of economics at the City University of New York and later the University of Basel.

Kapp's main contribution was the development of a theory of social costs that captures urgent socio-ecological problems and proposes preventative policies based on the precautionary principle.

His theory is in the tradition of various heterodox economic paradigms, such as ecological economics, Marxian economics, social economics, and institutional economics.

As such, Kapp's theory of social costs was an ongoing debate with neoclassical economics and the rise of neoliberalism.

He was an opponent of the compartmentalization of knowledge and championed, instead, the integration and humanization of the social sciences.

Kapp was born in Königsberg in 1910 as son of August Wilhelm Kapp, who was a teacher of physics.

In secondary school at the Hufengymnasium one of his teachers was the poet Ernst Wiechert End 1920s he started studying law and economics at the universities in Berlin and Königsberg.

This problem was first proposed by Ludwig von Mises in 1920, expounded by Friedrich Hayek and further debated in the 1920s and 1930s.

Kapp argued that a planned economy is "not doomed to autarky because there are ways to deal with the valuation problem so that trade and exchange with market economies can be organized".

He continued his studies in London and at the Graduate Institute of International Studies in Geneva, where in 1936 he received a Ph.D. in economics with his dissertation "Planwirtschaft und Aussenhandel".

In Geneva Kapp had met the people of the Frankfurt School, who emigrated to the US and settled as Institute for Social Research at the Columbia University, New York City.

In his 1936 dissertation Planwirtschaft und Aussenhandel contributed to the debate around the economic calculation problem, a criticism of central economic planning.

In 1937 they granted Kapp a scholarship.

From 1938 to 1945 he was an instructor in economics at the New York University and Columbia University in New York.

From 1945 to 1950 he was assistant professor of economics at the Wesleyan University in Middleton, Connecticut.

From 1950 to 1965 he was a professor of economics at the University of the City of New York.

He was among the first members of the Association for Evolutionary Economics (AFEE).

In 1965 he returned to Switzerland and was professor of economics at the University of Basel until 1976.

In that time he was also a visiting professor at the Ecole Pratique des Hautes Etudes, Sorbonne, Paris.

In 1976, Kapp had a fatal heart attack during a conference in Dubrovnik, Croatia.

Kapp's research interests ranged from economics, sociology, policy making and environmental science to the theory of knowledge, the history of economic thought, and many related topics.
