I am currently an Economist in the Human Development Team of the World Bank's Development Research Group. My primary research fields are development economics and economics of education, with a focus on violence and crime.
 

Combining experimental and non-experimental approaches, one strand of my research agenda studies how educational interventions and infrastructure projects implemented in developing countries can produce short- and long-term effects on their economic outcomesI also empirically analyze the interaction between crime and welfare, noting how criminal organizations usually harm countries' economic growth path. 

 

I have built original datasets from the ground up, by combining datasets from administrative and geographic records, with primary data collected by myself. have additional ongoing joint research projects in Chile, Ecuador, and Nicaragua. 

 

I obtained my Ph.D. and Master in Economics from Pontificia Universidad Católica de Chile in 2018 and 2016, respectively. I got my B.A. in Economics from ESEN in El Salvador, the country where I was born and raised.

Working Papers

 This paper provides experimental evidence of the effect of having peers with different propensities for violence in the context of an after-school program. By randomly assigning students to participate in the program with a set of similar or diverse peers in terms of violence, I measure the effects of segregation or integration on students' behavioral, neurophysiological, and academic outcomes. I also exploit a discontinuity around the median of the propensity for violence distribution to measure the impacts of segregation on marginal students. Results indicate that integrating students with different propensities for violence is better for both high and less violent children than segregating them. In particular, the intervention can have unintended effects on misbehavior and stress if highly violent students are segregated and treated separately from their less violent peers.

Unintended effects of Public Infrastructure: Labor, Education and Crime outcomes in El Salvador

Joint with Wilber Baires and Carlos Schmidt-Padilla

 

This paper exploits the construction of a highway in the north of El Salvador to measure short-term impacts of infrastructure on development outcomes, such as economic activity, labor force participation in the formal sector, school drop out, and criminal activities, using an IV approach. We find that the construction of this highway positively impacted relevant economic activities in the region. However, it reduced the labor force participation in the formal sector, for males and females between 15-19 years old, and increase dropout rates of men between 13-16 years old. To explain these results, we propose the gangs' arrival to municipalities nearby to the highway as a plausible mechanism that could be describing these results. In fact, we find that municipalities closer to the NTH faced an increase in the short-term homicides rate and extortions, without any effect in other non-gangs related crimes.

Violence and delinquency levels in Central America are among the highest in the world and constrain human capital acquisition. We conduct a randomized experiment in El Salvador designed to reduce this problem. The program works with 10-16-year-olds and combines a behavioral intervention with extra-curricular activities. We findthe program reduced bad behavior and absenteeism and improved student grades. By measuring brain activity, we show a key mechanism operates through emotional self-regulation, whereby treated adolescents become calmer when facing external stimuli. We also find positive spillovers on educational outcomes for other students in classes with treated students.
