Duopoly can be more anti-competitive than monopoly

  • Fujiwara, Kenji

Abstract

We prove two results on feedback equilibria under dynamic renewable resource duopoly. The linear feedback output is smallest, which sharply contrasts to the existing literature where it is largest. Moreover, prices in two feedback equilibria are higher than under monopoly.
