Lars P. Syll — What is this thing called ‘capital’?

Cambridge capital debate revisited.

Macroeconomics textbooks discuss ‘capital’ as if it were a well-defined concept — which it is not, except in a very special one-capital-good world (or under other unrealistically restrictive conditions). The problems of heterogeneous capital goods have also been ignored in the ‘rational expectations revolution’ and in virtually all econometric work.
