We study experimentally how to prevent bank runs using a mechanism inspired in Andolfatto et al. (2017). They propose a mechanism that eliminates bank runs as an equilibrium situation of the deposit contract and implements uniquely the efficient outcome. In our experimental enviroment bank runs may emerge both as a coordination failure in equilibrium and…
Based on predictions from a theoretical model in which voters’ tax compliance behavior is driven by fairness concerns we empirically analyze the channels through which ideological stances influence citizens’ willingness to pay taxes. By using heteroskedasticity-based instrumental variables we find that ideological differences between citizens and their governments cause a decrease in tax morale. An…
Cuando nos encontramos en las noticias cada día desastres naturales como incendios, inundaciones y epidemias, nos podemos plantear si es posible hacer algo para prevenir o saber más sobre dichos desastres. En esta charla veremos como es posible ayudar a mejorar nuestro conocimiento de los problemas relacionados con las ciencias de la vida y la…
Oligarchic majority rules bring the voice but no vote principle into effect. We prove characterizations of the oligarchic majority rules for both fixed and unrestricted societies and a binary agenda. This is a general class of rules that includes the simple majority rule as well as dictatorships. Suitable sets of axioms identify a subsociety whose members have…
In this talk we revisit common problems of Data Science [1, 2]. Specifically, we focus on the problem of locating a given number of hyperplanes minimizing a globalizing function of the closest distances from a set of points. Following an initial attempt in [3], we propose a general framework for the problem in which general…
Resumen Las alusiones al patrimonio y los negocios generados por la viuda de Fernando VII y reina regente, María Cristina de Borbón, y su segundo esposo, Agustín Fernando Muñoz, son una constante en la historiografía política española y en su día se consideró uno de los mayores escándalos de corrupción de la historia de España….
Abstract: I estimate the effect of being the best in the class} in the early years of schooling on future academic performance. I implement a novel methodology that does not require experimental data. My methodology exploits that some students are the best in the class because better students in the same school are assigned to…
Under spatial product differentiation and product design, we identify conditions for either excessive or insufficient firm entry. We extend previous settings, based on the Salop circular model, to analyze the combined role of positive demand elasticity and endogenous targeted product design. First, we show that, given the number of firms, the equilibrium level of targeted…
Abstract: Las disparidades regionales en los niveles de riesgo social amenazan la cohesión social en España, sin que puedan ser explicadas por las diferencias territoriales en el gasto social per cápita. Se estiman cuatro modelos DEA, uno por cada gran área de la política de gasto social (salud, educación y protección social) y para el…
A bilevel optimization problem consists in an optimization problem in which some of the constraints specify that a subset of variables must be an optimal solution to another optimization problem. This paradigm is particularly appropriate to model competition between agents, a leader and a follower, acting sequentially. In this talk I will first focus the…
