Seminario 20/15:Marco A. López (Universidad de Alicante): El impacto social de la Matemáticas

Matemáticas_primaria

En esta presentación se analizan las diferentes razones que contribuyen a que las Matemáticas se encuentren, hoy en día, en un primer plano de actualidad. Destacaríamos, en primer lugar, su presencia, como lenguaje y herramienta fundamental, en todas las ciencias (incluidas las sociales) y ramas de la tecnología. Nos detendremos en temas específicos en los…

Jan-J. Rückmann (University of Bergen): Stability of C-stationary Points for Mathematical Programs with Complementarity Constraints

We consider the class of mathematical programs with complementarity constraints (MPCC). Under an appropriate constraint qualification of Mangasarian-Fromovitz type we present a topological and an equivalent algebraic characterization of a stronglystable C-stationary point of MPCC. Strong stability refers to the local uniqueness, existence and continuous dependence of a solution for each sufficiently small perturbed problem…

Behzad Hezarkhani (Brunel University London). Gain-sharing in urban consolidation centers

Urbanconsolidation centers provide the logistical infrastructure for cooperationamong less-than-truckload carriers with contiguous destinations. The risingnumber of initiatives to establish and operate urban consolidation centers andtheir low success rates signal the need for better mechanisms to managecooperation in this context. We introduce and study cooperative situationscomprising a set of carriers with time sensitive deliveries who can…

Seminario 20/12: Sergio Hernández (Fragile Technologies, S.L.,Murcia) El comportamiento inteligente como un problema de optimización resoluble

Inteligencia

“Se dice que todo problema es un problema de optimización, pero no sabemos cómo convertir todos los problemas en simples funciones a optimizar y, aunque lo supiésemos, no sabemos resolver el problema de la optimización de forma general; sólo sabemos hacerlo con cierta eficiencia si el dominio es convexo y la función es convexa, continua…

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 20/06: 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…
