Seminario 21/16: Ricardo Martínez (Universidad de Granada): Compensation and sacrifice in the probabilistic rationing of indivisible units

20110423_Easter_eggs_(2)

We consider the problem of randomly allocating indivisible units of a resource among agents with conflicting claims on the resource. In the two-agent case, we characterize three focal rules combining axioms reflecting principles of compensation and sacrifice: probabilistic uniform awards, probabilistic uniform losses and probabilistic concede-and-divide. In the general case of n agents, the two…

Seminario 21/11: Juan D. Ternero (Universidad Pablo de Olavide): On the axiomatic approach to sharing the revenues from broadcasting sports leagues

deporte

We take the axiomatic approach to uncover the structure of the revenue-sharing problem from broadcasting sports leagues. Our starting point is to explore the implications of three basic axioms: additivity, order preservation and weak upper bound. We show that the combination of these axioms characterizes a large family of rules, which is made of compromises…

Seminario 21/9: Joaquin Sanchez Soriano (Universidad Miguel Hernández) Los problemas de atribución y sus aplicaciones desde la perspectiva de la teoría de juegos

estetoscopio

Un problema de atribución consiste simplemente en determinar cuál es la relevancia de una serie de factores para la consecución de un objetivo particular. Aunque la formulación del problema parece sencilla, no lo es tanto, y por ello existe toda una literatura sobre este problema en muy diversos campos. Por ejemplo, este tipo de problemas…

Seminario 20/24: Francesco Ciardiello (Sheffield University: On Pure-Strategy Nash Equilibria in a Duopolistic Market Share Model

negotiation

This paper develops a duopolistic discounted marketing model with linear advertising costs and advertised prices for mature markets still in expansion. Generic and predatory advertising effects are combined together in the model. We characterize a class of advertising models with some lowered production costs. For such a class of models, advertising investments have a no-free-riding…

Seminario 20/22: David Ríos (Real Academia de Ciencias), Adversarial Machine Learning: Perspectives from Adversarial Risk Analysis

Machine_learning

Adversarial Machine Learning (AML) is emerging as a major field aimed at the protection of automated ML systems against security threats. The majority of work in this area has built upon a game-theoretic framework by modelling a conflict between an attacker and a defender. After reviewing game-theoretic approaches to AML, we discuss the benefits that…

Seminario 20/18: Marina Segura (Universidad Complutense de Madrid) : Sustainable Management of the Supply Chain: Multiple Criteria Models

supply chain

La gestión de proveedores es un área estratégica de la cadena de suministro, que debe integrar tanto la homologación y selección como el seguimiento y segmentación de proveedores. El objetivo es identificar las relaciones más adecuadas entre la empresa y sus proveedores. La naturaleza multicriterio de la evaluación de proveedores, que debe tener en cuenta…

Seminario 20/17: Behzad Hezarkhani (Brunel University London). Gain-sharing in urban consolidation centers

Madrid_Cityscape

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 20/15: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…

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…
