LGBT+ Persons and Homophobia Prevalence Across Job Sectors: Survey Evidence from Mexico 

(joint with Emilio Gutierrez) - R&R, Labour Economics

Abstract: LGBTQ+ individuals may face particular labor market challenges concerning disclosure of their identity and the prevalence of homophobia. Employing an online survey in Mexico with two elicitation methods, we investigate the size of the LGBTQ+ population and homophobic sentiment across various subgroups. We find that around 5-13% of respondents self-identify as LGBTQ+, with some variation by age and job sectors. Homophobic sentiment is more prevalent when measured indirectly and is higher among males, older and less educated workers, and in less traditional sectors. Lastly, we uncover a negative correlation between homophobia and LGBTQ+ presence in labor markets, suggesting a need for policies to address these disparities.

Eye-opening Products: Uncertainty and Surprise in Cataract Surgery Outcomes 

(joint with Emilio Gutierrez and José Tudón) - under review

Abstract: For experience goods, benefits from consumption are ex-ante unknown, but revealed after repeated interactions. This uncertainty might lead to under-consumption. We develop a demand model with uncertainty in outcomes, for forward-looking consumers, and information revealed after the first interaction. We use data from a large cataract surgery provider in Mexico to estimate demand, and we exploit data from sales agents to identify structural demand parameters; namely, price elasticities and the value of the uncertain shock. We simulate counterfactual policies, showing that budget-neutral price changes are more efficient at increasing welfare and surgeries than persuasive advertising.

State Recreational Cannabis Laws and Racial Disparities in the Criminal Legal System 

(joint with Angélica Meinhofer and Jamein P. Cunningham)

Abstract: Racial disparities in enforcement of drug prohibition are longstanding, with Black communities disproportionately affected. We study the effect of cannabis legalization on racial disparities in criminal justice outcomes using a difference-in-differences framework. Legalization led to significant declines in cannabis arrests for White and Black populations, but did not eliminate racial disparities. Total arrests were unchanged due to offsetting increases in arrests for less serious quality-of-life offenses, particularly among Black populations. Incarceration rates for drug offenses only declined for White populations. Lastly, we do not find evidence of increased criminal activity among Black populations, suggesting this mechanism cannot explain arrest increases.

Promotions Measured with Error: Implications for Health Policy and Firm Behavior 

(joint with Emilio Gutierrez and José Tudón)

Abstract: We estimate price elasticities and promotion effects across many consumer goods, leveraging nationwide retail data with observable promotional discounts from purchase receipts. We contrast price elasticities with and without promotions, and document demand shifts due to promotions' non-price attributes. We repeat this exercise using a traditional, algorithm-driven approach that imputes promotions whenever prices decrease, leading to underestimated promotion effects and overestimated price effects. We emphasize the importance of these distinctions through several policy-relevant findings: reduced frequency of promotions following "sin food"  taxes, similar promotion elasticities for healthy and unhealthy products, and higher sensitivity to promotions among high-BMI consumers.

Going Big in Health: Effect of a Large-Scale Preventive Health Policy 

(joint with Arturo Aguilar and Ricardo Gómez-Carrera)

Abstract: Despite the benefits of preventive healthcare, uptake is typically low. This paper studies how embedding healthcare in a conditional cash transfer program affects utilization by exploiting the roll-out of Progresa in Mexico. We estimate a sizable 12% increase in outpatient visits at public clinics, driven by children and women aged 20-49. This translates into improvements in reproductive healthcare and screenings for chronic diseases. However, these effects are also accompanied by increased congestion, measured with waiting times, and reductions in quality of care. Overall, this suggests that the benefits of this policy lever may carry unintended displacement effects.

Delays in Death Reports and their Implications for Tracking the Evolution of COVID-19 

(joint with Emilio Gutierrez and Tiago Tavares; Covid Economics Working Paper)  

Abstract: Understanding the determinants and implications of delays in reporting COVID-19 deaths is important for managing the epidemic. Contrasting England and Mexico, we document that reporting delays in Mexico are larger on average, exhibit higher geographic heterogeneity, and are more responsive to the total number of occurred deaths in a given location-date. We then estimate simple SIR models for each country to illustrate the implications of not accounting for reporting delays. Our results highlight the fact that low and middle-income countries are likely to face additional challenges during the pandemic due to lower quality of real-time information.  

Over-the-Counter Access Regulations: Evidence from an Antibiotics Law in Mexico

Abstract: Regulations restricting over-the-counter (OTC) access to drugs are important policy tools for mitigating self-medication and encouraging doctor visits. However, they may have unintended consequences when access to affordable healthcare is lacking. This paper estimates the effect of a law restricting OTC sales of antibiotics in Mexico on public hospital admission rates. I find a temporary but significant decline of around 40% in admission rates due to infections. This effect is driven by viral infections, adult patients, and patients from higher education municipalities. OTC regulations may inadvertently increase the socioeconomic health gradient unless accompanied by policies that expand affordable healthcare.
