Affirmative action in college admission and the proficiency of high school students

Economic theory suggests that a¢ rmative action can either reduce or enhance incentives to invest in human capital. Empirical evidence on this matter, however, is still lacking. Using di¤erence in di¤er- ence estimates, this paper evaluates the e¤ects of the quota system in the admission to Brazilian public universities on the pro ciency of high school students. Our ndings show that favored groups attained lower scores, suggesting a negative link between a¢ rmative action and incentives for e¤ort and skill acquisition.

Optimal performance fee and flow of funds in asset management contracts

This paper investigates the importance of ow of funds as an implicit incentive in the asset management industry. We build a two-period bi- nomial moral hazard model to explain the trade-o¤s between ow, per- formance and fees where e¤ort depends on the combination of implicit ( ow of funds) and explicit (performance fee) incentives. Two cases are considered. With full commitment, the investor s relevant trade-o¤ is to give up expected return in the second period vis-à-vis to induce e¤ort in the rst period. The more concerned the investor is with today s pay- o¤, the more willing he will be to give up expected return in the second period by penalizing negative excess return in the rst period. Without full commitment, the investor learns some symmetric and imperfect infor- mation about the ability of the manager to obtain positive excess return. In this case, observed returns reveal ability as well as e¤ort choices. We show that powerful implicit incentives may explain the ow-performance relationship with a numerical solution. Besides, risk aversion explains the complementarity between performance fee and ow of funds.
