The second edition of this anthology contains twenty-two classic and more recent pivotal investigations in the philosophy of economics. Recommended readings now follow the selections. Daniel M. Hausman has expanded and updated coverage of such key areas as positivism and economic methodology, and special methodological problems and perspectives. His revised introduction and section introductions not only situate each contribution in its historical and analytical context but also explore current directions in the definition and refinement of economic methodology. The collection will demonstrate to students and professionals in the discipline and other social sciences and the humanities, as well as to a more general audience, what kind of science economics is.
