Delegated Portfolio Management, No Churning, and Relative Performance-Based Incentive/Sorting Schemes.
We show that optimal delegated portfolio management contracts-which serve to screen out uninformed agents and reward potentially informed agents sufficiently to compensate their opportunity and/or effort costs-need not imply churning, or randomised trading if uninformed, by the able screened agents, despite limited liability for them which limits the amount of screenable heterogeneity among agents.
