An empirical investigation of the welfare effects of banning wholesale price discrimination

Contents:

Author Info

  • Sofia Berto Villas-Boas

Abstract

Economic theory does not provide sharp predictions on the welfare effects of banning wholesale price discrimination: if downstream cost differences exist, then discrimination shifts production inefficiently, toward high-cost retailers, so a ban increases welfare; if differences in price elasticity of demand across retailers exist, discrimination may increase welfare if quantity sold increases, so a ban reduces welfare. Using retail prices and quantities of coffee brands sold by German retailers, I estimate a model of demand and supply and separate cost and demand differences. Simulating a ban on wholesale price discrimination has positive welfare effects in this market, and less if downstream cost differences shrink, or with less competition. Copyright (c) 2009, RAND.
