Abstract

Conventional linear benchmarked contracts tend to cause excessive pegging to the benchmark and thus price distortion of stocks in the benchmark. This paper studies the optimal delegation contract when there is principal-agent friction. Specifically, it explores the impacts of incorporating the risk of invested portfolio in the contract on optimal strategies of the principal and the agent as well as on equilibrium asset prices. When agency friction is severe, the optimal contract provides rewards for portfolio risk to improve risk sharing and grants compensation for index return to propel the agent to deviate from pegging to index. In equilibrium, the principal conducts index investment while the agent invests only in individual risky assets, and price distortion caused by agency friction is mitigated.

考虑投资组合风险的最优委托契约

传统的线性基准合约往往会导致与基准的过度挂钩，从而导致基准股票的价格扭曲。本文研究了存在委托代理摩擦时的最优委托契约。具体而言，本文探讨了将投资组合风险纳入契约对委托人和代理人的最优策略以及均衡资产价格的影响。当代理摩擦严重时，最优契约为投资组合风险提供奖励以提高风险分担，为指数回报提供补偿以推动代理偏离钉住指数。在均衡状态下，委托人进行指数投资，代理人只投资单项风险资产，减轻了代理摩擦引起的价格扭曲。
