Contests (or tournaments) are pervasive in organizations. They help performance evaluation by eliminating common shocks affecting agents' performance. However, tournaments are less effective when participants have heterogeneous ability because participants may conclude that the ability gap is too large to be overcome by their effort. Our theoretical analysis shows that a similar loss of motivation arises when tournaments take place over multiple periods because interim performance acts in a way that is similar to heterogeneous ability. Analyzing the sales contests organized by a commodities company, we document that winning participants decrease their effort as their lead extends, whereas the effort of trailing participants fades only when the gap to a winning position is very large. We also show that, on average, when contests are introduced they induce a higher level of effort among participants, although the incentives weaken as the number of participants increases. Finally, we demonstrate that although retailers respond to the multiple performance dimensions of the incentive program in part by shifting effort toward sales of more expensive products, they channel most of the increased effort toward reaching more customers.tournaments, relative performance compensation, dynamic incentives, multitasking

We use Spain's Equality Law to test for the existence of agency problems between party leaders and their constituents. The law mandates a 40 percent female quota on electoral lists in towns with populations above 5,000. Using pre-and postquota data by party and municipality, we implement a triple-difference design. We find that female quotas resulted in slightly better electoral results for the parties that were most affected by the quota. Our evidence shows that party leaders were not maximizing electoral results prior to the quota, suggesting the existence of agency problems that hinder female representation in political institutions.

This paper presents the results from a field experiment that examines the effects of nonfinancial performance feedback on the behavior of professionals working for an insurance repair company. We vary the frequency (weekly and monthly) and the level of detail of the feedback that the 800 professionals receive. Contrary to what we would expect if these professionals conformed to the model of the Bayesian decision maker, more (and more frequent) information does not always help improve performance. In fact, we find that professionals achieve the best outcomes when they receive detailed but infrequent (monthly) feedback. The treatment groups with frequent feedback, regardless of how detailed it is, perform no better than the control group (with monthly and aggregate information). The results are consistent with the information in the latest feedback report being most salient and professionals in the weekly treatments overweighting their most recent performance, hampering their ability to learn.
