Teachers are the most fundamental input of students' learning. For this reason, developing teaching skills is a policy priority for most governments around the world. We experimentally evaluate the effectiveness of "Let's All Learn to Read," a one-year professional development program that...

This paper explores the effects of weather-induced rural-urban migration on urban labor and housing markets in Brazil. In order to identify causal effects, it uses weather shocks to the rural municipalities of origin of migrants. We show that larger migration shocks led to an increase in...

This article relies on a large-scale field experiment in Mexico to measure the effects of two ability-grouping models (tracking and heterogeneous/bimodal groups) on student learning outcomes during middle school. Both strategies yielded an average learning gain of 0.08 of a standard deviation....

We conduct a meta-analysis of 44 studies and 68 different managerial skills training programs, with the aim of identifying program characteristics that can lead to more effective public policies promoting firm growth and entrepreneurship. We synthesize 431 estimates to assess the effects of...

We exploit the randomized evaluation of a remedying education intervention that improved the reading skills of low-performing third grade students in Colombia, to study whether providing educational support to low-achieving students affects the academic performance of their higher-achieving...

By exploiting spatial variation in import exposure arising from initial differences in industry specialization, we analyze how local labor markets in Mexico adjusted to increased Chinese-import competition over different time horizons. The initial adjustment to the shock took various forms: a...

This chapter examines the redistributive preferences of Latin Americans and investigates the factors that shape them. Using a detailed survey in eight Latin American countries, the study sheds new light on redistributive preferences and explores which aspects of redistribution are more popular...

Currently available asymptotic results in the literature suggest that matching estimators have higher variance than reweighting estimators. The extant literature comparing the finite sample properties of matching to specific reweighting estimators, however, has concluded that reweighting...

This dissertation consists of three essays whose unifying topical theme is the study and application of semiparametric methods for the evaluation of social programs. The first essay evaluates the federal urban Empowerment Zone (EZ) program using an inverse probability weighting (IPW)...

The laws that regulate relations between firms and workers in Mexico distinguish sharply between salaried and non-salaried workers, and they are at the root of the existence of informality. This paper provides a clear definition of informality, distinguishing it from illegality. Using Mexico's...
