We study the impact of contractual incentives on the risk-taking behavior and the performance of US mutual funds. We measure incentives using the shape, i.e. concavity, of the fee structure in the advisory contract. Compared to the standard linear fee structure, a concave structure should create a disincentive to take more risk. Our results show that a high incentive contract induces managers to take more risk and reduces the funds’ probability of survival. On the other hand, high-incentive funds deliver higher return. The net of these two effects is that incentives increase the risk-adjusted performance of the fund. In particular, the top incentive quintile of funds outperforms the bottom incentive quintile by about 2.7 percent per year. Moreover, the performance of the high-incentive funds is highly persistent. High-incentive winner funds from one year have a positive alpha of 41 basis points per month in the following year. By focusing on the funds' holdings, we show that active portfolio rebalancing is the main channel through which incentives increase performance.
Agency theory claims that investors can alleviate some agency problems through high-incentive contracts for managers. Such contracts would mean that managers’ pay-offs were more closely related to their performance, which could increase managers’ efforts and thus lead to better performance. At the same time, high-incentive contracts would also induce managers to take more risks. The net effect is less clear. Indeed, if extra performance compensates only for the additional risk taken, high incentives are not beneficial for the principal. In fact, it has been argued that higher incentives lead managers to take excessive risks per unit of performance delivered.
