Abstract Los juegos TU como funciones de particiones son estructuras apropiadas para modelizar las ganancias/costes de una coalición teniendo en cuenta como se organizan el resto de los jugadores. En esta charla revisaremos algunos valores propuestos en la literatura, centrándonos en sus propiedades. En particular, revisaremos el valor de Myerson (Myerson 1977), el valor de…
Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…
Abstract An effective climate agreement is urgently required, yet conflict between parties prevails over cooperation. Thanks to advances in science it is now possible to quantify the global carbon budget, the amount of available cumulative CO2 emissions before crossing the 2oC threshold (Meinshausen et al., 2009). Countries carbon claims, however, exceed this. Historically such situations have been tackled…
Abstract: Despite the fact that the use of sporadic advertising schedules is well established in both the advertising literature and market place, the marketing channel literature that focuses on vertical interactions has consistently prescribed continuous advertising strategies over time. This paper investigates, in a bilateral monopoly context a situation in which a manufacturer and a…
Abstract: En este trabajo analizamos un conjunto de “concursos de belleza” (“Beauty Contests”- Nagel, AER 1995) jugados en el contexto de redes económicas/sociales. Los Beauty Contests han sido utilizados en campos como las finanzas y en el estudio de la racionalidad limitada de los agentes económicos. En concreto, fue uno de los primeros juegos en…
Abstract: The paper focus on the dynamics of organizations and how they design its future according to the interest of their members. Agents are grouped into three classes, high, medium and low productivity. We analyze the evolution of organizations which take decisions by majority voting. We focus on the evolution of the political power and…
Abstract Several power indices were introduced in order to account for different aspects of decisional situations. The talk presents how to deal with those situations, commonly arising in politics, in which the agents have some incompatibilities. Some comments on existing power indices and how communication structures and restricted games may allow a better evaluation of…
Abstract This paper studies the interbank liquidity game where banks are located on a network and may access their direct neighbors’ liquidity holdings. We investigate patterns and directions of welfare-improving transfers in arbitrary networks. More specifically, we use a geometric approach to characterise two general cases – where the welfare improvement is accompanied by a…
Abstract In this paper we analyze a two period contest in which agents may become bankrupt at the end of the first period. A bankrupt agent is excluded from the contest in the second period of the game. We investigate the existence of a subgame perfect equilibrium in pure strategies. We distinguish between a borrowing…
