Seminario 19/36: Martine Labbé (Computer Science Department, Université Libre de Bruxelles INRIA, Lille) Bilevel optimisation and pricing problems


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…

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


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 19/28: Jose Luis García Lapresta (UVLL) – Escalas cualitativas no uniformes: un enfoque ordinal


Algunas de las escalas cualitativas utilizadas por diferentes instituciones y organismos no son uniformes: los agentes pueden percibir que la proximidad psicológica entre cada par de términos consecutivos de la escala no sea idéntica. En esta charla se abordan las escalas cualitativas no uniformes a través de la noción de medida de proximidad ordinal y…

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


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


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….

Seminario 19/19: Carmen Herrero (Universidad de Alicante) The balanced worth: a procedure to evaluate performance in terms of ordered attributes


There are many problems in the social sciences that refer to the evaluation of the relative performance of some populations when their members’ achievements are described by a distribution of outcomes over a set of ordered categories. A new method for the evaluation of this type of problems is presented here. That method, called balanced…

Seminario 19/13: Francisco Cabo (U. Valladolid) – Interaction and imitation between Sanchos and Quixotes: A misleading evolutionary equilibrium


The paper analyzes the interaction between individuals belonging to two distinct populations, who share the same strategy set but differ in their payoff matrices. A two-population evolutionary game describes this interaction, that presents a double dimension. On the one hand, agents in one population play a game against individuals within their own and also the…

Seminario19/14: José Carlos González Pimienta (UC3M) – Costly voting: a large-scale real effort experiment.


We test the turnout predictions of the canonical costly voting model through a large-scale, real effort experiment. We recruit 1,200  participants through Amazon’s Mechanical Turk and employ a 2 x 2 between subjects design encompassing small ( N = 30) and large ( N = 300) elections, as well as close and lopsided. As predicted,…

Seminario 18/24: Vita Zhukova (UCAM) – The Role of Firms’ Trustworthiness in Business Angels’ Investment. Experimental Evidence from 3-player Trust Game


Business Angels are private individuals who invest their personal financial resources in new and growing small firms. To study Business Angels’decisions we design an experiment based on the Trust Game (Berg et al., 1995) and add a third party, the Business Angel, who decides whether and how much to invest in a firm that is…

Seminario 18/20: Ana B. Ania-Martínez (U. of Vienna) – Laboratory federalism with public funds sharing


Abstract: We explore the role of public funds sharing in the  framework of laboratory federalism, viewed as a learning process of policy innovation and imitation. In a model of decentralized, rich-to-poor redistribution with labor mobility, such a learning dynamics leads to the complete erosion of the welfare state. We show that suitably designed funds sharing schemes can correct this…
