Theory and evidence in psychology and economics about motivation crowding out: A possible convergence?
Résumé
The empirical relevance of motivation crowding out is a controversial issue in economics and psychology. As pointed out already by Frey and Jegen (2001), this is partly due to the historical development of two distinct and parallel strands of literature that stem from different theoretical traditions, have radically different tenets and therefore, are difficult to reconcile. In this survey, we go back to the details of the debates that took place independently among psychologists and economists, and sketch an integrative interdisciplinary approach likely to favor a more fruitful collaboration between economics and psychology. From this perspective, experimental economics (both field and laboratory) is viewed as a major research field shedding new light on the conditions of relevance of motivation crowding out.
