Seminario 20/09: Alfonso Rosa (UM): Preventing (panic) bank runs.

bank run

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…

Seminario 20/08: David Rodríguez-Justicia (URV): Voting with tax compliance: Ideological stances and tax morale

Votación_del_Congreso_Nacional_de_Chile_(1826)

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…

Seminario 20/07: David Conesa (Universidad de Valencia). ¿Puede la Bioestadística arreglar el mundo?

network

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…

Seminario 20/06: Jose Carlos Rodríguez Alcantud (Universidad de Salamanca): Simple majorities with voice but no vote

Votación_del_Congreso_Nacional_de_Chile_(1826)

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…

Specialization, generic firms and market competition (2019): Carlo Reggiani (University of Manchester)

The choice of specialization affects firms’ brand perception by consumers and it is of crucial importance for their profitability in competitive markets. We model how firms choose specialization through a spatial non-localized competition framework that naturally allows for markets where not all brands are available. The model predicts the co-existence of generic and specialized firms,…

Seminario 20/05: Justo Puerto, IMUS, Universidad de Sevilla. Generalized Multisource Regression: A framework for locating hyperplanes to fitting sets of points

fig_tesis_laura

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…

Seminario 20/04: Miguel A. López Morell (Universidad de Murcia) – El patrimonio y los negocios de la reina María Cristina y Fernando Muñoz. Los frutos de una regencia interesada.

Spanish_State_opening_of_Parliament_1834

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….
