Why do certain ideas gain currency in economics while others fall by the wayside? Paul Krugman argues that the unwillingness of mainstream economists to think about what they could not formalize led them to ignore ideas that turn out, in retrospect, to have been very good ones. Krugman examines the course of economic geograph and development theory to shed light on the nature of economic inquiry. He traces how development theory lost its huge initial influence and virtually disappeared from economic discourse after it became clear that many of the theory's main insights could not be clearly modeled. Economic geography seems to have fared even worse, as economists shied away from grappling with questions about space—such as the size, location, or even existence of cities—because the "terrain was seen as unsuitable for the tools at hand." Krugman's book, however, is not a call to abandon economic modeling. He concludes with a reminder of why insisting on the use of models may be right, even when these sometimes lead economists to overlook good ideas. He also recaps the discussion of development and economic geography with a commentary on recent developments in those fields and areas where further inquiry looks most promising.
A stimulating essay by one of the world's most thoughtful and innovative economists.
