"Reverse Revolving Doors: The Influence of Interest Groups on Legislative Voting" with Miguel Alquézar-Yus

[Draft] [Coverage: ProMarket]

Using the alphabetic allocation of seats in the European Parliament, we show that former employees of interest groups influence the voting behavior of their colleagues when sitting together. When the subject of the vote is relevant to the interest group, the probability that nearby colleagues cast the same ballot increases by 2.4 percent and that of abstention decreases by 9 percent, while no effect is detected for other vote subjects. These probabilities increase for votes about budgetary allocations and they are comparable to those of sitting beside party motion leaders. Revolving doors are problematic for the political process also when working in reverse.


"Gender Differences in Early Occupational Choices: Evidence from Medical Specialty Selection" with Agnès Charpin

[Draft][SSRN][EUI WP]

Empirical evidence shows that men and women hold different types of occupations. It is however difficult to disentangle the channels via which these differences come about because observed equilibrium outcomes arise from preferences of agents on both sides of the market, and search and matching frictions. This paper relies on a unique labour market setting allowing to isolate the supply side factors driving gender-based occupational segregation. We find that supply-side factors are important. Female and male medical students facing the same pool of available positions make drastically different occupational decisions, even at the top of the performance distribution. Women prefer occupations characterised by lower expected earnings and time requirements, less competition, and a higher social contribution. We also find evidence suggesting that when constrained in their choices, women have a stronger preference for the location in which they are going to live compared to their male counterparts.


"E-learning Engagement Gap During School Closures: Differences by Academic Performance" with Alaitz Ayarza-Astigarraga and Marta C. Lopes

[Draft]

We study the impact of COVID-19 school closures on differences in online learning usage by regional academic performance. Using data from Google Trends in Italy, we find that during the first lockdown, regions with a previously lower academic performance increased their searches for e-learning tools more than higher-performing regions. Analysing school administrative and survey data before the pandemic, we find that both teachers and students in lower performing regions were using no less e-learning tools than higher performing ones. These two findings suggest that the COVID-19 shock widened the e-learning usage gap between academically lower and higher-performing regions. Exploiting the regional variation in school closure mandates during the 2020/2021 academic year, we report that the patterns detected after the first lockdown were no longer present. Regions with different previous academic performance had the same response in terms of online learning usage when faced with stricter school closures.

"Effects of Early Infancy Care on Subsequent Infant Health"

[Draft available upon request]

This paper studies the causal effects of additional early infancy care on several subsequent fertility outcomes. I exploit the eligibility discontinuities of a welfare policy in Spain that entitles parents of newborns with birth weights below certain thresholds to receive monetary payments to devote themselves to the care of their child as well as to fully funded social security contributions. Using birth register data, I measure the effect of the reception of such social benefits on health outcomes of subsequent newborns and subsequent pregnancy conditions.
