We introduce a novel approach for organizing behavior and explaining cooperation in repeated games. Our approach is based on the idea that players differ according to an inherent propensity to cooperate that systematically affects behavior and cooperation levels. We formulate the empirical...

Using abstracted grades and other data from Add Health, we investigate the effects of cumulative high school GPA on educational attainment and labor market earnings among a sample of young adults (ages 24-34). We estimate several models with an extensive list of control variables and high school...

We derive nonparametric bounds for local average treatment effects without requiring the exclusion restriction assumption to hold or an outcome with a bounded support. Instead, we employ assumptions requiring weak monotonicity of mean potential outcomes within or across subpopulations defined by...

We develop a game-theoretic model of lobbying in which contributions buy access to politicians. The analysis considers the claim that the rich are better off because they have more access to politicians, and that contribution limits reduce the rich-interest advantage, resulting in less-skewed...

An advocate for a special interest provides information to an uninformed planner for her to consider in making a sequence of important decisions. Although the advocate may have valuable information for the planner, it is is also known that the advocate is biased and will distort her advice if...

In this paper we provide some sufficient conditions for the differentiability of the value function in a class of infinite-horizon continuous-time models of convex optimization arising in economics. We dispense with an interiority condition which is quite restrictive in constrained optimization...

Data from 76 experimental welfare-to-work programs conducted in the United States between 1983 and 1998 are used to investigate whether the impacts of such programs on employment had been improving over time and whether specific program features influencing such changes can be identified. Over...

A decision maker must divide a resource between multiple agents. The decision maker prefers to award the resource to the most-qualified agents, but he is initially uncertain about agent qualifications. Although he can learn about qualifications by granting the agents “access (e.g., by taking...

We use a game theoretic model of contests to assess different explanations for the male performance advantage in competition. Comparing the testable predictions of the model with the empirical evidence, we reject explanations involving male overcon- fidence, misperceptions about relative...
