About

I'm an Assistant Professor of Economics in the Department of International Affairs at Texas A&M University. My research interests span the fields of environmental and development economics.

I completed my Ph.D. at the University of British Columbia in November 2023 with a disciplinary focus on Environmental and Development Economics. I hold MA, BA, and B.Sc degrees in economics and industrial engineering from Universidad de los Andes.

Outside of academia, I have worked for the Development Impact Evaluation unit (DIME) at the World Bank, the Education Division and the Caribbean Country Department at the Inter-American Development Bank (IADB), the Center for Studies on Economic Development (CEDE) at Universidad de los Andes and at Fedesarrollo.

Working Papers

• "Too Polluted to Sin? Dirty Skies, Crime, and Adaptation Responses in Mexico City"
Abstract | Paper

Awards: Lasserre-Renzetti Prize for best student paper at the Canadian Resource and Environmental Economics Association (CREEA) conference October 2021

This paper estimates the non-monotonic effects of air pollution on criminal activity in a highly polluted mega-city. The identification strategy relies on highly dimensional fixed-effect models, non-parametric estimations of dose-response functions, and an instrumental variable approach that employs wind speed and wind direction as instruments for air pollution. My results uncover a causal, inverted U-shaped relationship between air pollution and crime. Specifically, there is an inflection point after which marginal increases in air pollution negatively affect criminal activity. By examining the emotional tone of social media posts, I further explore how air pollution may influence individuals' emotional states and mobility decisions, ultimately contributing to the observed inverted U-shape. Overall, my findings shed light on how environmental regulation tailored to reduce air pollution must consider the presence of behavioral responses in their design.

• "Yes They Can: Empowering Women"
with Thorsten Rogall, August, 2022
      Abstract | Paper

We study how giving women political and domestic independence can lead to persistent female empowerment and overall welfare improvements. Using Rwandan post-genocide data, we exploit local variation in gender imbalances that caused a power vacuum which women filled as household heads and local politicians. In office, they provide more public goods. Overall, in female-led villages, women are healthier, better educated, wealthier, less likely to accept and experience domestic violence, and enjoy more sexual and financial autonomy. Importantly, younger women are carrying these changes and gender norms changed. In villages were men stayed in power, we find negative or no effects.

• "Toxic Recycling: The Cost of Used Lead-Acid Battery Processing in Mexico"
with Erin Litzow, Bianca Cecato and Mauricio Romero
      Abstract | Paper

There is no known safe level of lead pollution exposure. Many countries have taken steps in the last half century to remove lead from their environments, but, at times, these policies can cause pollution sources to shift to countries with weaker regulatory environments. Previous studies have theorized about and empirically documented this ‘pollution haven’ phenomenon, but few have examined the costs borne by recipient communities. In the setting we study, a 2009 tightening of environmental standards in the United States caused used lead-acid battery recycling, an industry that emits large amounts of lead pollution, to shift to Mexico. We estimate the effects of this increased industrial activity and associated pollution on student learning in recipient communities in Mexico. We use data from a nationwide test in Spanish and math, conducted from 2006 to 2013. We compare test scores before and after the 2009 U.S. policy change among students attending schools near and downwind of Mexican recycling facilities and those studying farther away. We estimate effects on test scores of negative 0.05-0.09 standard deviations, with effects being slightly stronger for math than Spanish. Comparing dynamic effects across grades, we find suggestive evidence that effects are stronger for students who were younger in 2009. We also compare effects across communities, showing that the costs to education are heavily concentrated in communities that were already worse off before the 2009 change in lead-acid battery recycling activity. The results of our study underline the importance of considering unintended consequences and cross-border spillovers when regulating toxic pollutants. The heterogeneity of effects across communities highlights the need for more research on the costs of lead pollution exposure in low- and middle-income countries, where the vast majority of exposure occurs today.

• "Valuing Blue Carbon: Carbon Sequestration Benefits Provided by the Marine Protected Areas in Colombia"
with Jorge H Maldonado
Plos One, May 2015, 10(5)
      Abstract | Paper | Journal

Marine protected areas are aimed to protect and conserve key ecosystems for the provision of a number of ecosystem services that are the basis for numerous economic activities. Among the several services that these areas provide, the capacity of sequestering (capturing and storing) organic carbon is a regulating service, provided mainly by mangroves and seagrasses, that gains importance as alternatives for mitigating global warming become a priority in the international agenda. The objective of this study is to value the services associated with the capture and storage of oceanic carbon, known as Blue Carbon, provided by a new network of marine protected areas in Colombia. We approach the monetary value associated to these services through the simulation of a hypothetical market for oceanic carbon. To do that, we construct a benefit function that considers the capacity of mangroves and seagrasses for capturing and storing blue carbon, and simulate scenarios for the variation of key variables such as the market carbon price, the discount rate, the natural rate of loss of the ecosystems, and the expectations about the post-Kyoto negotiations. The results indicate that the expected benefits associated to carbon capture and storage provided by these ecosystems are substantial but highly dependent on the expectations in terms of the negotiations surrounding the extension of the Kyoto Protocol and the dynamics of the carbon credit's demand and supply. We also find that the natural loss rate of these ecosystems does not seem to have a significant effect on the annual value of the benefits. This approach constitutes one of the first attempts to value blue carbon as one of the services provided by conservation.
