The Cambridge capital controversy – sometimes called "the capital controversy" or "the two Cambridges debate" – refers to a theoretical and mathematical debate during the 1960s among economists concerning the nature and role of capital goods and the critique of the dominant  neoclassical vision of aggregate production and distribution. The name arises because of the location of the principals involved in the controversy: the debate was largely between economists such as Joan Robinson and Piero Sraffa at the University of Cambridge in England and economists such as Paul Samuelson and Robert Solow at the Massachusetts Institute of Technology, in Cambridge, Massachusetts. The two schools are often labeled "Sraffian" or "neo-Ricardian" and "neoclassical", respectively.
