Bio

I am a postdoctoral fellow at the Golub Capital Social Impact Lab and the Stanford Digital Economy Lab, where I collaborate with Susan Athey, Erik Brynjolfsson, and Sandy Pentland.

I study how digital technologies enhance governance—and therefore prosperity—in developing contexts. My recent work is centered on reducing misinformation sharing and enhancing online deliberation through the use of Generative AI.

I received my Ph.D. in Political Economy and Government (PEG) from Harvard. I graduated from Instituto Tecnológico Autónomo de México (ITAM) in Mexico City with a B.A. in Economics and a B.A. in Political Science.

    Abstract

    Social distancing policies have been widely used to curb the spread of infectious diseases such as COVID-19, but assessing their effectiveness is challenging. This study shows that widely-used methods to estimate the effects of such policies, like Two-way Fixed Effects and Difference-in-Differences, are highly sensitive to accounting, or failing to account, for the simultaneous adoption of policies and the presence of spillovers across geographies stemming from human movement. By estimating a series of nonparametric models on fine-grained mobility, epidemiological, and policy data from Mexico during the COVID-19 pandemic, this research shows that failing to consider confounders, interactions, and spillovers can change the magnitude and the sign of estimated policy effects, hampering the design of optimal public policies.
