英文摘要:
We develop a continuous-time dynamic multi-agent contracting model in which the principal is unsure about the distributions of the project's terminal payoffs and worries about model misspecification. With model uncertainty, workers' wages depend on the outputs of other unrelated projects and the optimal contracts exhibit overdetermination. We demonstrate an inverse U-shaped relationship between the extent of overdetermination and group size. Moreover, model uncertainty induces wage compression, especially in small firms as the empirical evidence demonstrates. Finally, expanding the group size increases the average project value by mitigating the negative impacts of ambiguity.
中文摘要:
文章提出了一个连续时间动态多代理契约模型。在这个模型中,委托人对项目终端收益的分布不确定,并且担心模型误设。研究发现,在存在模型不确定性的情况下,工人的工资取决于其他不相关项目的产出。最优合同呈现出超定(overdetermination)特征,这种超定特征与群体规模存在倒U型关系。同时,模型不确定性会导致工资压缩。从实证证据来看,这种工资压缩现象在小公司中尤为明显。进一步研究表明,扩大群体规模能够减轻模糊性的负面影响,从而增加平均项目价值。
