 Furthermore, many of the same methodologists and historians have argued that economics is not only an object of social inquiry, but that it can be a tool of social inquiry into science. By studying the incentive structure of scientific disciplines and the implicit or explicit market forces impinging on research (including of course research in economics), it should be possible to write the economics of science and the economics of economics itself (Hands 1995, Hull 1988, Leonard 2002, Mirowski and Sent 2002).
