Limit properties of Bertrand equilibria with exogenous entry
AbstractFor a large class of demand and cost functions, we characterize the limit equilibrium set under Bertrand oligopoly when entry is exogenous. Unless average cost is constant, we find that the folk theorem of perfect competition necessarily fails. We also relate our results to those in Novshek and Roy Chowdhury (2003).
