"Using data from multiple-period math competitions, we show that males outperform females of similar ability during the first period. However, the male advantage is not found in any subsequent period of competition, or even after a two-week break from competition. Some evidence suggests that...

Pre-College human capital investment occurs within a competitive environment and depends on market incentives created by Affirmative Action (AA) in college admissions. These policies affect mechanisms for rank-order allocation of college seats, and alter the relative competition between blacks...

A number of recent studies show that males may increase their performance by more than females in response to competitive incentives. The literature suggests that such a male competitive advantage may contribute to observed gender gaps in labor force pay and achievement. Understanding which...

We present results from a multiple public goods experiment, where each public good produces benefits only if total contributions to it reach a minimum threshold. The experiment allows us to compare a subject's behavior in a benchmark treatment with a single public good and in treatments with...

When multiple charities, social programs and community projects simultaneously vie for funding, donors risk miscoordinating their contributions leading to an inefficient distribution of funding across projects. Community chests and other intermediary organizations facilitate coordination among...

Experiments involving multiple public goods with contribution thresholds capture many features of charitable giving environments in which donors try to coordinate their contributions across various potential recipients. We present results from a laboratory experiment that introduces endowment...
