Krugman and Stiglitz — nothing but neoliberal alibis31 January, 2017 at 20:40 | Posted in Economics | Leave a comment
Mirowski’s concern to disabuse his readers of the notion that the wing of neoliberal doctrine disseminated by neoclassical economists could ever be reformed produces some of the best sections of the book. His portrait of an economics profession in haggard disarray in the aftermath of the crisis is both comic and tragic …
Little in the discipline has changed in the wake of the crisis. Mirowski thinks that this is at least in part a result of the impotence of the loyal opposition — those economists such as Joseph Stiglitz or Paul Krugman who attempt to oppose the more viciously neoliberal articulations of economic theory from within the camp of neoclassical economics. Though Krugman and Stiglitz have attacked concepts like the efficient markets hypothesis … Mirowski argues that their attempt to do so while retaining the basic theoretical architecture of neoclassicism has rendered them doubly ineffective.
First, their adoption of the battery of assumptions that accompany most neoclassical theorizing — about representative agents, treating information like any other commodity, and so on — make it nearly impossible to conclusively rebut arguments like the efficient markets hypothesis. Instead, they end up tinkering with it, introducing a nuance here or a qualification there. This tinkering causes their arguments to be more or less ignored in neoclassical pedagogy, as economists more favorably inclined toward hard neoliberal arguments can easily ignore such revisions and hold that the basic thrust of the theory is still correct. Stiglitz’s and Krugman’s arguments, while receiving circulation through the popular press, utterly fail to transform the discipline.
