Surplus sharing in Cournot oligopoly
研究了在古诺竞争下，相同企业如何通过不同需求函数影响消费者剩余、行业利润和无谓损失的分配，为理解市场均衡的福利结果提供框架。
We characterize equilibria of oligopolistic markets where identical firms with constant marginal cost compete à la Cournot. For given maximal willingness to pay and maximal total demand, we first identify all combinations of equilibrium consumer surplus and industry profit that can arise from arbitrary demand functions. Then, as a further restriction, we fix the average willingness to pay above marginal cost (i.e., first‐best surplus) and identify all possible triples of consumer surplus, industry profit, and deadweight loss.
