Welfare consequence of an asymmetric regulation in a mixed Bertrand duopoly

Contents:

Author Info

  • Matsumura, Toshihiro

Abstract

I investigate an asymmetric duopoly where a public enterprise must supply the demand it faces, while a private enterprise has no such obligation. I show that such an asymmetric regulation yields the first-best outcome (Walrasian equilibrium).
