Portfolio Delegation Under Short-Selling Constraints
We study delegated portfolio management when the managerÂ´s ability to short-sell is restricted.Contrary to previous results, we show that under moral hazard, linear performance-adjusted contracts do provide portfolio managers with incentives to gather information.We find that the risk-averse managerÂ´s effort is an increasing function of her share in the portfolioÂ´s return.This result affects the risk-averse investorÂ´s choice of contracts.Unlike previous results, the purely risk-sharing contract is now shown to be suboptimal.Using numerical methods we show that under optimal linear contract, managerÂ´s share in the portfolio return is higher than what it is under a purely risk sharing contract
