Retaining your corporate income tax base: Effects of a tax haven shareholdership reform in Ecuador
écrit avec with Pierre Bachas and Alex Bajaña
Can a country reduce its exposure to tax havens, and what are the consequences? We analyze the effects of the 2015 corporate tax surcharge applied by Ecuador to all domestic firms with shareholders from tax havens. This reform was made possible by the implementation of a mandatory ownership registry in 2012. We implement a difference-in-differences estimation that compares firms demonstrating pre-reform tax haven shareholdership versus other internationally owned firms (without tax haven presence). Exposed firms reduce their reported shareholder linkages to tax havens by 17pp on average, with approximately one-third of exposed firms ceasing observable ties to tax havens entirely. We document a nearly complete substitution (14pp) towards foreign non-haven ownership, hinting at a layering response. Yet, we also find a small increase in domestic shareholdership, and a modest rise in taxable profits and tax liability, which suggests that substituting to alternate avoidance strategies is not frictionless.

Bounding Treatment Effect Heterogeneity with an Application to Labor Economics
Uncovering the nature and the magnitude of the heterogeneity in the impact of a public policy is central for practitioners. Using an interactive fixed effects (IFE) model in the context of panel data to accommodate non-parallel evolutions of untreated potential outcomes across groups, I aim to provide two measures of the aforesaid heterogeneity. First and foremost, a bound of the variance of the treatment effects, and, under stronger assumptions, a characterization of the full distribution of treatment effects on the treated (QTT). I then review the available results in the literature using deconvolutions and instrumental variables in quantile regressions to estimate QTTs, and sketch some potential applications in the field of Labor Economics.

Moral Force: Leaders's actions, within-city social distancing and COVID-19
écrit avec María Montoya-Aguirre, Federico Daverio and Max Ponce de León
I exploited a natural experiment within India's public engineering institutes to study how increased exposure to students from different castes affects job market and academic outcomes, as well as support towards affirmative action (AA) policies and mental well-being. Leveraging a setting where negative stereotypes about ability are very salient due to intense competition and explicit caste-based affirmative action policies, I used roommate exposure as an opportunity to identify possible discrimination from upper-caste groups and changes in self-confidence among disadvantaged groups that are possibly relevant to broader affirmative action policies in India.
Pilot results consistently indicate negative effects on disadvantaged groups' academic skills and job market outcomes when assigned to mixed-caste rooms in their first year. Academic interactions between roommates are lower when they live in mixed-caste rooms, but no change in social interactions is observed. Finally, support for attitudes towards affirmative action policies reduces for both upper and lower caste groups when they live in mixed-caste rooms, even though lower-caste students believe AA policies benefit them. A large-scale survey will further explore these findings, investigating mechanisms like discrimination, self-confidence, networks, and information.

Moral Force: Leaders's actions, within-city social distancing and COVID-19
écrit avec María Montoya-Aguirre, Federico Daverio and Max Ponce de León
We study how a populist leader influenced social distancing behavior and affected COVID-19 outcomes among his supporters during the early stages of the pandemic in Mexico. President Andrés Manuel López Obrador (AMLO) defied government stay-at-home recommendations, prompting dismissal by the COVID-19 Czar, who described him as a moral force rather than a contagion threat. Leveraging granular mobility and political support data, we employ a difference-in-difference research design, revealing that post-Czar statement, pro-AMLO electoral precincts increased out-of-home mobility by up to 2% two weeks later. Concurrently, pro-AMLO municipalities experienced elevated COVID-19 positivity, hospitalization, and case-fatality rates. These results underscore the impact of populist leaders on public health behaviors and the risks when scientists align with populist rhetoric.

Immigration and Cultural Heterogeneity: Evidence from two Decades in Europe
écrit avec Y. Elkhateeb and J. Valette
This paper investigates the impact of immigration on cultural heterogeneity in Europe from 2004 to 2018 at the regional level. It combines European Social Survey data, to measure cultural heterogeneity across several cultural traits, with immigrant data from the European Labor Force Survey. Our findings show that overall cultural heterogeneity is negatively influenced by inflows of immigrants. The results indicate that while low-skilled and non-European immigrants increase cultural heterogeneity by introducing new values in destination countries, this effect fades rapidly with assimilation. It is also outweighed by a stronger cultural reaction of natives to the higher share of high-skilled immigrants within Europe that correlates with reduced cultural fractionalization among natives. By emphasizing birthplace as a relevant cleavage in studying cultural divisions, our study provides insights into how immigration can shape the distribution of cultural values in modern societies.
