摘要：Disentangling peer effects from other confounding effects is difficult, and separately identifying endogenous and contextual effects is impossible for the linear-in-means model. This study confronts these problems by using spatial autoregressive models with group fixed effects. The nonlinearity introduced by the variations in the peer measurements provides information to identify both endogenous and contextual effects, thus resolving the reflection problem. The group fixed effects term capture...

摘要：This article presents evidence on the child-quantity/child-quality trade-off using quasi-experimental variation due to twin births and preferences for a mixed sibling sex composition, as well as ethnic differences in the effects of these variables. Our sample includes groups with very high fertility. An innovation in our econometric approach is the juxtaposition of results from multiple instrumental variables strategies, capturing the effects of fertility over different ranges for different so...

摘要：The importance of fair and equal treatment of workers is at the heart of the debate in organizational management. In this regard, we study how reward schemes and production technologies affect effort provision in teams. Our experimental results demonstrate that unequal rewards can potentially increase productivity by facilitating coordination and that the effect strongly interacts with the exact shape of the production function. Taken together, our data highlight the relevance of the productio...

摘要：The Great Depression offers a unique laboratory to investigate the causal impact of migration on local labor markets. We use variation in the generosity of New Deal programs and extreme weather events to instrument for migrant flows to and from U. S. cities. In-migration had little effect on the hourly earnings of existing residents. Instead, in-migration prompted some residents to move away and others to lose weeks of work or access to relief jobs. For every 10 arrivals, we estimate that 1.9 ...

摘要：We use unique longitudinal data to provide direct evidence about interracial friendships at different stages of college and to provide new evidence about some of the reasons for the observed patterns of interaction. We find that, while much sorting exists at all stages of college, black and white students are, in reality, very compatible as friends; randomly assigned roommates of different races are as likely to become friends as randomly assigned roommates of the same race. Further, we find t...

摘要：We study investment tournaments, a class of decision problems involving gradual allocation of investment among several alternatives whose values are subject to shocks. The decision maker's payoff is determined by the final values of the alternatives. An important example of such tournaments is the career choice problem, since a person typically starts by investing in learning several professions. We show that in many cases it is optimal for the decision maker to allocate all resources to the m...
