Mathematical Modelling and Ideology in the Economics Academy: competing explanations of the failings of the modern discipline?
This paper is closed for comments.
The widespread and long-lived failings of academic economics are due to an overreliance on largely inappropriate formalistic methods of analysis. This is an assessment I have long maintained. Many heterodox economists, however, appear to hold instead that the central problem is a form of political-economic ideology. Specifically, it is widely contended in heterodox circles that the discipline goes astray just because many economists are committed to a portrayal of the market economy as a (overly) smoothly or efficiently functioning system or some such, a portrayal that, whether sincerely held or otherwise, is inconsistent with the workings of social reality. Here I critically examine the contention that a form of political-economic ideology of this sort is the primary problem and assess its explanatory power. I conclude that the contention does not fare very well. I do not, though, deny that ideology of some sort has a major impact on the output of the modern economics academy. However it is of a different nature to any form typically attributed to the mainstream, and works in somewhat indirect and complex ways. Having raised the question of the impact of ideology I take the opportunity to explore its play in the economics academy more generally.
