This paper proposes a new mechanism linking trade and wage inequality in developing countries—the quality-upgrading mechanism—and investigates its empirical implications in panel data on Mexican manufacturing plants. In a model with heterogeneous plants and quality differentiatiation, more productive plants produce higher-quality goods than less productive(More)

We construct a new index of media slant that measures whether a news outlet's language is more similar to a congressional Republican or Democrat. We apply the measure to study the market forces that determine political content in the news. We estimate a model of newspaper demand that incorporates slant explicitly, estimate the slant that would be chosen if(More)
This paper establishes the relatively weak conditions under which causal inferences from a regression-discontinuity (RD) analysis can be as credible as those from a randomized experiment, and hence under which the validity of the RD design can be tested by examining whether or not there is a discontinuity in any predetermined (or " baseline ") variables at(More)
We demonstrate the existence of multiple dimensions of private information in the long-term care insurance market. Two types of people purchase insurance: individuals with private information that they are high risk and individuals with private information that they have strong taste for insurance. Ex post, the former are higher risk than insurance(More)
Most Difference-inDifference (DD) papers rely on many years of data and focus on serially correlated outcomes. Yet almost all these papers ignore the bias in the estimated standard errors that serial correlation introduces. This is especially troubling because the independent variable of interest in DD estimation (e.g. the passage of law) is itself very(More)

This paper develops a new framework for examining the distributional consequences of international trade that incorporates firm and worker heterogeneity, search and matching frictions in the labor market, and screening of workers by firms. Larger firms pay higher wages and exporters pay higher wages than non-exporters. The opening of trade enhances wage(More)
We examine how the speed of learning and best-response processes depends on homophily: the tendency of agents to associate disproportionately with those having similar traits. When agents' beliefs or behaviors are developed by averaging what they see among their neighbors, then convergence to a consensus is slowed by the presence of homophily, but is not(More)

We study the long run effects of one of the most ambitious place based economic development policies in U.S. history: the Tennessee Valley Authority (TVA). Using a rich panel dataset of counties, we conduct an evaluation of the dynamic effects of the TVA on local economies in the seventy years following the program's inception. We find that the TVA led to(More)

Advances in communication and transportation technologies have the potential to bring people closer together and create a 'global village'. However , they also allow heterogenous agents to segregate along special interests which gives rise to communities fragmented by type rather than geography. We show that lower communication costs should always decrease(More)
In many field settings, participants sort among environments based on their preferences , beliefs, and skills. Experiments, however, often ignore the potential impact of such sorting. We demonstrate the importance of sorting for experiments, in the domain of social preferences. When individuals are constrained to play a dictator game, 61% of the subjects(More)
