Women often find themselves in teams that hinder their productivity and earnings. We analyze the role of homophily and gender stereotypes in preferences for team formation and examine the effect of information on changing these preferences. We find that women are expected to perform better in...

We show that professional soccer players exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that a player breaches the rules of the game, measured by the referee's assignment of cards,...

A body of literature suggests that ethnic heterogeneity limits economic growth. This paper provides microeconometric evidence on the direct effect of ethnic divisions on productivity. In team production at a plant in Kenya, an upstream worker supplies and distributes flowers to two downstream...

A longstanding distinction in psychology is between implicit and explicit preferences. Implicit preferences are ordinarily measured by observing non-choice data, such as response time. In this paper we introduce a method for inferring implicit preferences directly from choices. The necessary...

We conducted a lab experiment to examine (1) whether luck-based income influences honesty in a subsequent, unrelated decision, (2) whether the perceived agency over an uncertain event affects the interplay between luck and honesty, and (3) whether accumulated previous luck-based incomes...

Does being lucky (or unlucky) affect honest decision-making? We examine (1) whether luck-based income strengthens or erodes the moral value of honesty; (2) whether the perceived level of agency over an uncertain event affects the relationship between luck and honesty; and (3) whether accumulated...

We consider infinite-horizon bargaining in which an uninformed seller sequentially makes a price offer to a privately informed buyer who decides whether to accept or reject it in every bargaining round. Existing theories suggest that the presence (absence) of an arbitrarily small outside option...

In an experiment that elicits subjects' willingness to pay (WTP) for the outcome of a lottery, we confirm the fourfold pattern of risk attitudes described by Kahneman and Tversky. In addition, we document a systematic effect of stake sizes on the magnitude and sign of the relative risk premium,...
