Abstract
This paper examines the empirical relevance of the capital controversy. The price model of Sraffa and the dual models of the price and quantity systems of von Neumann become the basis of the investigation. In the course of the controversy, it proved easy to construct theoretical examples which contradicted the fundamental neoclassical hypothesis of an inverse capital demand function. This paper presents empirical examples for the first time. Thiry-two input-output tables from the OECD database serve as data. As a result, one envelope is found which involves reswitching. Reverse substitution of labour or reverse capital deepening are observed in about 3.65% of tested cases: they involve at least two switchpoints.
Key Words: Cambridge controversy Reswitching Reverse capital deepening Sraffavon Neumann Linear programming
