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…

Seminario 19/29: Annick Laruelle (UPV/EHU). Cost-Benefit analysis in participatory budgeting

Presupuestos

Abstract: In participatory budgeting, citizens are invited to vote on different projects. Those with the most votes are chosen and implemented. The voting rules used in practice are usually based on single winner elections. A shortcoming of using these rules is that they do not take into account the costs of the projects, although those…

Seminario 19/26: Javier Rubio-Herrero, St. Mary’s University,Texas (USA) Estimación de flujos desagregados de mercancías por medio de un algoritmo genético

genes

Presentamos un método para estimar de manera indirecta las cantidades transportadas de ciertos productos entre dos regiones en aquellos casos en los que solamente están disponibles los datos de la suma de sus flujos. Este método se basa en la aplicación de un modelo gravitacional clásico introducido en un problema de optimización. El objetivo de…

Seminario 19/23: Overqualification and skills mismatches among immigrants: the impact of host language proficiency

inmigracion

Abstract: Examining the determinants of qualification and skills mismatches has become a recurrent theme in the literature. Educational mismatches have serious consequences for individuals and can seriously hamper wages, job satisfaction and labour market prospects. These effects can be drammatical among immigrants, since they add up to an already disadvantaged position in the labour market….
