Long-Run Competition in Capacity, Short-Run Competition in Price, and the Cournot Model
研究企业先选择产能再进行价格竞争的均衡性质,发现古诺结果不太可能出现,均衡比古诺模型更具竞争性,且企业规模不对称和价格分散是混合策略的结果。
In this article we investigate the nature of equilibrium in markets in which firms choose the scale of operation before they make pricing decisions. We analyze a duopoly model in which firms choose their capacities before engaging in Bertrand-like price competition. We demonstrate that the Cournot outcome is unlikely to emerge in such markets and that the equilibrium tends to be more competitive than the Cournot model would predict. In addition, our results indicate a tendency toward asymmetric firm sizes and price dispersion that results from the mixed strategies firms use in equilibrium.
