David M. Kreps argues that the discipline must account for dynamic personal tastes when it comes to understanding social exchange, emphasizing human resource management and on-the-job behavior. He develops formal models that illustrate the power of intrinsic motivation and show why applying extrinsic incentives can be counterproductive. Kreps weighs the advantages and disadvantages of the principle de gustibus non est disputandum: there is no arguing about tastes. He calls for a new era of economics in which preferences are taken into account―and not for granted.
Arguing About Tastes concludes with responses by the distinguished economists Alessandra Casella and Joseph E. Stiglitz and a final reply by Kreps.
