The degeneration of workers’ cooperatives under endogenous membership in mixed oligopoly
构建了一个工人合作社与利润最大化企业竞争的混合寡头模型，将合作社成员制视为内生，分析导致合作社成员数相对于总员工数减少的退化因素。
Abstract We propose a new model of mixed oligopoly where a workers’ cooperative firm competes with a number of profit-maximizing companies. Building upon a large empirical evidence, we innovate as compared to the traditional literature on the objective function of the cooperative; moreover, its membership is treated as endogenous in the Cournot–Nash equilibrium. We show which factors may be responsible for the degeneration of the workers’ cooperative firm, which occurs when the number of its members shrinks with respect to the overall employees.
