We analyze the factors that determine the number of clicks in the Like button in online teaching videos. We perform a study in a sample of Spanish-language teaching videos in the area of Microeconomics. The results show that users prefer short online teaching videos. Moreover, some other...

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 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 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 run an experiment with users of Internet forums. In a dictator game, we find that the level of altruism is positively related to the activity in the forum. In a public good game, there is no relation between cooperation in the game and contribution to the content of the forum. Subjects are...

We report experimental evidence on the effect of observability of actions on bank runs. We model depositors’ decision-making in a sequential framework, with three depositors located at the nodes of a network. Depositors observe the other depositors’ actions only if connected by the network....

We assess the impact of cognitive abilities on withdrawal decisions in a bank-run game. In our setup, depositors choose sequentially between withdrawing or keeping their funds deposited in a common bank. They may observe previous decisions depending on the information structure. Theoretically,...
