Production Externalities, Congruity of Aggregate Signals, and Optimal Task Assignments*
研究生产外部性如何影响任务分配问题，分析在基于不完美总体信号的激励下，多样任务分配能否克服努力分配扭曲，并形式化了相关直觉。
Abstract In this paper, we consider the role of production externalities in the task assignment problem. Milgrom and Roberts (1992) suggest that complementarities available when agents are assigned to diverse tasks are necessary to overcome distortions in effort allocations caused by an inability to fine‐tune incentives when agents' compensation is based on aggregate imperfect signals. Our analysis formalizes this intuition in a setting that encompasses externalities under both diverse and similar task assignments.
