We provide evidence on a gender bias in risk aversion among students of economics in Spain. In a sample of 1947 multiple choice exams with penalization for errors, we find that women consistently answer less questions, while differences in marks are not significant. These empirical results are...

We study a coordination problem where agents act sequentially. Agents are embedded in an observation network that allows them to observe the actions of their neighbors. We find that coordination failures do not occur if there exists a sufficiently large clique. Its existence is necessary and...

A distinctive feature of recent revolutions was the key role of social media (e.g. Facebook, Twitter and YouTube). In a simple model we assume that while social media allow to observe all previous decisions, mass media only give aggregate information about the state of a revolt. We show, first,...

We report experimental evidence on gender differences in financial decision that involves three depositors choosing between waiting or withdrawing their money from a common bank. We find that the position in the line, the fact of being observed and the observed decisions are key determinants to...

We run an experiment with users of internet message boards. We find that forum users cooperate more with partners of their own forum than with partners from a different forum but they are equally altruistic when they made a gift to a partner of their forum or from another one. We also find that...

We model unemployment and credit cycle dynamics as a Markov-switching process with two states to identify labor market slacks i.e., periods of unemployment above its natural rate. Our results for the US economy between 1955 and 2015 show that credit contractions improve the identification of...

This study explores student responses to AI-generated educational content, specifically a teaching video delivered by an AI-replicant of their professor. Utilizing ChatGPT-4 for scripting and Heygen technology for avatar creation, the research investigates whether students' awareness of the AI's...
