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,: 417f  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. Source: Wikipedia (en)
