We devise an analytical framework where the distribution of factor income across agents and the distribution of labor earnings across workers is influenced by the possibility of profit sharing with workers. Firms choose periodically to compensate workers with only a real base wage or a share of profits in addition to this real base wage as alternative productivity-enhancing strategies. As supported by robust empirical evidence, labor productivity is higher in profit-sharing firms than in non-sharing firms. The frequency distribution of productivity-enhancing strategies and labor productivity across firms are co-evolutionarily time-varying, which impacts on the distribution of factor income between profits and wages and thereby on the rates of employment and output growth, as well as on the distribution of labor earnings across workers. Heterogeneity in productivity-enhancing strategies across firms (and hence labor earnings inequality across workers) may be a stable long-run equilibrium outcome. This polymorphic equilibrium features the frequency of profit-sharing firms and the employment rate varying positively (negatively) with the real base wage (profit-sharing coefficient). Yet the employment rate is path dependent in the polymorphic equilibrium. As shown analytically and with numerical simulations, the microdynamics landscape is shaped by the real base wage and the profit-sharing coefficient as bifurcation parameters.

我们设计了一个分析框架，其中，与代理人分享利润的可能性会影响代理人之间要素收入的分配以及工人间劳动收入的分配。企业会定期选择仅以实际基本工资或利润的一部分来补偿工人，以此作为提高生产率的替代策略。在有力的经验证据的支持下，分享利润的公司的劳动生产率要高于不分享公司的劳动生产率。企业间提高生产率的战略和劳动生产率的频率分布是时变的，这会影响利润和工资之间的要素收入分配，从而影响就业率和产出增长率以及分配工人的劳动收入。公司间提高生产率的策略的异质性（以及工人间劳动收入的不平等）可能是稳定的长期均衡结果。这种多态均衡的特征是利润分享公司的频率和就业率随实际基本工资（利润分享系数）正（负）变化。然而，就业率在多态均衡中与路径有关。如分析和数值模拟所示，微观动力学格局是由实际基本工资和利润分配系数作为分叉参数而形成的。这种多态均衡的特征是利润分享公司的频率和就业率随实际基本工资（利润分享系数）正（负）变化。然而，就业率在多态均衡中与路径有关。如分析和数值模拟所示，微观动力学格局是由实际基本工资和利润分配系数作为分叉参数而形成的。这种多态均衡的特征是利润分享公司的频率和就业率随实际基本工资（利润分享系数）正（负）变化。然而，就业率在多态均衡中与路径有关。如分析和数值模拟所示，微观动力学格局是由实际基本工资和利润分配系数作为分叉参数而形成的。
