Novshek on the existence of cournot equilibrium

This paper examines the existence of n-firm Cournot equilibrium in a market for a single homogeneous commodity. It proves that if each firm's marginal revenue declines as the aggregate output of other firms increases (which is implied by concave inverse demand) then a Cournot equilibrium exists, without assuming that firms have nondecreasing marginal cost or identical forosaludlatam.com by: Remark 5 (Cournot Equilibrium Existence in Mixed Strategies). If we were to allow mixed strategies of rms, existence of Cournot equilibrium would follow from the Nash existence theorem under conditions (i)-(iii), at least when the number of states of nature is nite. The simplicity and robustness of Examples 1 and 2 indicate that Bayesian Cournot equilibrium existence with always non-negative prices is a much scarcer phenomenon than existence when negative prices are allowed to arise (and thus also scarcer than the existence in the complete information case). 5 When negative prices are possible (which is Cited by:
