Social Welfare in a Common Property Oligopoly
Output in a Markov Nash-Cournot equilibrium to a noncooperative differential game in which m oligopolists extract a common property nonrenewable resource is bounded by the output of m-firm and (m - 1)-firm static oligopolies. The author discusses the welfare effects of the number of firms and of the divergence between private and social discount rates. He compares extraction under the Markov and open-loop equilibria and then offers an explanation for the possibility that the resource is exhausted instantaneously in a continuous time game. This explanation does not depend on the fact that the period of commitment is infinitesimal.
