讲座摘要:In a multi-agent contracting setting, agents' performances are related due to both correlated noise and effort spillovers. We study the optimal linear contract when agents are risk averse. Imposing compensation weights on peer performance helps to filter out common noise, which relaxes the participation constraint (hedge effect). However, it may also reduce the incentive to exert effort due to effort spillovers, which therefore tightens the incentive compatibility constraint (incentive effect). We show that the optimal compensation sensitivity is determined by the dot product between the pure hedge vector and spillover vector. Furthermore, we propose an index called informativeness along the spillover direction to capture the balance between the hedge and incentive effects. As a result, both the effort and profit induced in equilibrium are positively related to this index. Finally, we demonstrate the disparity between spillover depth (measuring the strength of the spillover effect) and spillover width (summarizing the density of spillover structure).
