We assess the extent to which a country's external capital structure can aid in mitigating the macroeconomic impact of oil price shocks. We study two Caribbean economies highly vulnerable to oil price shocks, an oil-importer (Jamaica) and an oil-exporter (Trinidad and Tobago). From a...

This paper uses data from 10 at-scale field experiments in four countries to estimate the effect of inquiry- and problem-based pedagogy (IPP) on students' mathematics and science test scores. IPP creates active problem-solving opportunities in settings that provide meaning to the child. Students...

Is a school's impact on high-stakes test scores a good measure of its overall impact on students? Do parents value school impacts on tests, longer-run outcomes, or both? To answer the first question, we exploit quasi-random school assignments and data from Trinidad and Tobago. We construct...

Using exogenous secondary school assignments to remove self-selection bias to schools and peers within schools, I credibly estimate both (1) the effect of attending schools with higher-achieving peers, and (2) the direct effect of short-run peer quality improvements within schools, on the same...

In Trinidad and Tobago students are assigned to secondary schools after fifth grade based on achievement tests, leading to large differences in the school environments to which students of differing initial levels of achievement are exposed. Using both a regression discontinuity design and...

Existing studies on single-sex schooling suffer from biases because students who attend single-sex schools differ in unmeasured ways from those who do not. In Trinidad and Tobago students are assigned to secondary schools based on an algorithm allowing one to address self-selection bias and...

This paper uses a natural field experiment to examine the effectiveness of specific nudges on tax compliance amongst firms and the self-employed in the Dominican Republic. In collaboration with the Dominican Republic's tax authority, we designed messages for more than 28,000 self-employed...

This paper summarizes the findings from the first randomized evaluation of a job training program in Latin America. Between 2001 and 2005 the government of the Dominican Republic operated a subsidized training program for low-income youth in urban areas. The program featured several weeks of...

We study the interaction between job and soft skills training on expectations and labor market outcomes in the context of a youth training program in the Dominican Republic. Program applicants were randomly assigned to one of 3 modalities: a full treatment consisting of hard and soft skills...

The potential benefits of demand side interventions may leak into the profits of suppliers whenever there is market power. In those situations, governments could attempt to regulate the market or to increase competition. We provide the first experimental evidence on the effect of increased...
