Title: «The effects of obesity on human capital accumulation: Evidence from Spain» with Raquel Carrasco Perea.



Abstract: Childhood obesity is a pressing health issue in developed countries, including Spain, where high rates persist. This study investigates the impact of childhood obesity on academic performance and human capital accumulation among Andalusian high school students. Taking advantage of exogenous obesity peer effects, gender-specific class obesity prevalence is used as an instrumental variable for individual obesity. The findings reveal that obesity negatively impacts academic achievement, particularly in cognitive abilities, financial abilities and English grades for boys and girls, and mathematics and overall grades for girls, with the latter experiencing higher effects. Teacher discrimination, psychological well-being, time preferences, and expectations about labor market discrimination are identified as important factors driving these effects, while the role of bullying remains inconclusive. These results highlight the significance of addressing childhood obesity and its implications for educational outcomes.

Title: «The development of rationality in games with hidden information», with A. Alfonso, P. Brañas-Garza, I. Brocas, J. D. Carrillo, and M. J. Vázquez.


Abstract: We present the first lab-in-the-field experiment that studies the strategic behavior of privately informed children and adolescents. We recruited 1662 participants from 8 to 18 years old to play a game of two-sided asymmetric information. We show that participants of all ages understand the fundamental relationship between action and private information (first level of rationality or ‘choice monotonicity’). Older participants are more likely to select strategies that match basic features of the optimal strategy compared to their younger peers (second level of rationality or ‘strategic consistency’). However, in none of our grades the individuals react to variations in incentives triggered by changes in game structure (third level of rationality or ‘environmental variability’). Remarkably, participants with heightened emotional intelligence exhibit a greater tendency to play strategically, best respond to others and, consequently, achieve higher payoffs. It reveals a strong, robust connection between affective theory-of-mind and cognitive theory-of-mind.
