Rosenberg argues that economists have embraced the methodology of scientific research programs, and the writings of Imre Lakatos, at the same time that philosophers have been abandoning that approach. According to Rosenberg, the methodology of scientific research programs appears to allow some work in economics, which is neither tested nor testable, to be “scientific” nonetheless. That is, MSRP justifies some current practices which look hard to justify on strict falsificationist, or dogmatic positivist, grounds.

As made manifest by Clower's comments on their “science fiction” nature, general equilibrium theories present such peculiar and puzzling features that the methodologist must perforce seek some specific methodological accommodation for this part of economic theory. The role played by such theories in contemporary economics is so fundamental that the impossibility of appraising them by means of any version of falsificationism, and their patent lack of empirical content if approached with the conceptual devices of the methodology of scientific research programs, (...) have prompted several scholars interested in the methodology of economics to search for a reasonable way out.

Weintraub is not really interested in whether economics is “science” or not. “Economists are not so unsophisticated as to think that calling economics a ‘science’ says anything about what economists do or should do”. But can it really be a matter of indifference to him whether the subject has the character of chemistry as opposed to literary criticism?

Mark Blaug’s normative methodology of economics is an attempt to articulate certain intuitions about how economic science could be improved by making it more “realistic”. I discuss two such articulations, one in terms of falsificationist principles, the other in terms of an alleged trade-off between relevance and mathematical rigour. My conclusion is that Blaug’s methodology is itself unrealistic, both descriptively and normatively. His (well intended) methodological prescriptions for the improvement of economics are not based on a systematic, consistent, descriptively adequate, (...) and normatively viable account. I suggest that Blaug’s intuitions can be developed into a more realistic account by incorporating the analysis of two further topics: economic modelling and the institutions of academic research.
