STOCHASTIC COST‐VOLUME‐PROFIT ANALYSIS IN A COMPETITIVE OLIGOPOLY
将随机成本-数量-利润模型扩展到寡头竞争环境，通过博弈论和纳什均衡求解，帮助企业评估竞争实力，并支持基于资本资产定价理论的风险度量调整。
ABSTRACT Previous stochastic cost‐volume‐profit (CVP) models have assumed that the firm was operating under either perfect competition or monopolistic conditions. This paper presents a stochastic CVP model applicable to oligopolistic competition. Each firm is assumed to maximize a linear function of the expected value and the standard deviation of its random profits. The result is a game‐theoretic model that is solved using the concept of a Nash equilibrium. The results of the model are used to examine a firm's competitive strength. The model can be easily modified to accommodate a measure of risk based on the capital asset pricing theory.
