Did independence push Latin America down a growth-inequality trade-off? During the late colonial decades, the region completed two centuries of growth unmatched anywhere and inequality reached spectacular heights. During the half century after insurgency and independence, inequality fell steeply...

With the signing of the North American Free Trade Agreement (NAFTA) in 1994, Mexico entered a bilateral free trade agreement which not only lowered its own tariffs on imports but also lowered tariffs on its exports to the U.S. We find that women's relative wage increased, particularly during the...

Tenancy has been a means for labor to advance their socio-economic condition in agriculture yet in Brazil and Latin America, tenancy rates are low compared to the U.S. and the OECD countries. We test for the importance of insecure property rights in Brazil on the reluctance of landowners to rent...

This paper considers the observational implications of social influences on adoption decisions for an environment of perfect foresight adopters. We argue that social influences can produce two observable effects: 1) discontinuities in unconditional adoption curves and 2) pattern reversals in...

There is a large theoretical literature on methods for estimating causal effects under unconfoundedness, exogeneity, or selection--on--observables type assumptions using matching or propensity score methods. Much of this literature is highly technical and has not made inroads into empirical...

The purpose of this paper is to help empirical economists think through when and how to weight the data used in estimation. We start by distinguishing two purposes of estimation: to estimate population descriptive statistics and to estimate causal effects. In the former type of research,...

We characterize and demonstrate a solution method for an optimal commodity (sales) tax problem consisting of multiple goods, heterogeneous agents, and a nonconvex policy maker optimization problem. Our approach allows for more dimensions of heterogeneity than has been previously possible,...

It is common in regression discontinuity analysis to control for high order (third, fourth, or higher) polynomials of the forcing variable. We argue that estimators for causal effects based on such methods can be misleading, and we recommend researchers do not use them, and instead use...

We test for sorting of workers between and within industrial sectors in a directed search model with coordination frictions. We fit the model to sector-specific vacancy and output data along with publicly-available statistics that characterize the distribution of worker and employer wage...

Empirical papers in economics often describe heuristically how their estimates depend on intuitive features of the data. We propose two quantitative measures of this relationship that can be computed at negligible cost even for complex models. We show that our measures can be informative about...
