A Suggestion for Clarifying the Study of Dissent in Economics

Abstract

The answer to this question might seem obvious: like Everest, dissent and controversy are there. However, for most academic economists, dissent is negligible and controversy is far less important than it is commonly made out to be. To draw attention to disagreements between economists is to offer a distorted picture of what economics is about. Instead, they argue, the focus of attention should be on the enormous extent to which economists agree. From this perspective, dissent and controversy are not worth much attention. Another justification for studying controversy is that it is exciting. James Tobin once argued (explaining the appeal of Keynesian economics) that when you are young you like theoretical controversy: you like hearing about the good guys and the bad guys, and the idea of being on the side of progressive thought and against an encrusted orthodoxy. Similarly, historians are interested in dissent and controversy in much the same way that writers of thrillers are more interested in neighborhoods where murders happen than in ones where everyone just watches TV all day! What these answers have in common is that they associate controversy and dissent with the pathology of the subject. Disagreement is something to be avoided and which reflects badly on the profession. The most famous representative of this view was probably Alfred Marshall. In his attempt to establish economics as a science that carried authority with the public, he studiously refrained (most of the time) from entering into controversy, and he sought to reconcile within his own work divergent trends that were tearing apart the subject in other countries.
