This paper suggests a new approach for centrality measures for general (weighted) networks taking into account the importance for cohesion and relative power of connections. While existing literature either ignores the importance for cohesion or measures it by analyzing consequences arising from...

Economic agents often care about their relative well-being: they compare with their neighbors in a social network. In this case, which network structures permit stable allocations? We construct a model in which agents' payoffs depend on the ranking of their allocations among the payoffs of their...

Economic agents care about their relative well-being, and the comparisons are usually local. We capture this using a network model, in which an agent's payoff depends on the ranking of their allocation among their network neighbors’. Given a network, an allocation is called α-stable if no...

This discussion paper resulted in a publication in 'Social Choice and Welfare', 2012, 39, 721-735. <P> Many economic organizations have some relational structure, meaning that economic agents do not only differ with respect to certain individual characteristics such as wealth and preferences, but...</p>

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect...

Suppose some individuals are allowed to engage in different groups at the same time and they generate a certain welfare by cooperation. Finding appropriate ways for distributing this welfare is a non-trivial issue. The purpose of this work is to analyze two-stage allocation procedures where...

In this paper, we describe a series of laboratory experiments that implement specific examples of a more general network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or...

El presente estudio se enfoca en analizar los patrones de migración en Colombia desde la perspectiva de la teoría de redes. El análisis está dividido en dos partes: la primera es la formulación de un modelo basado en la teoría de redes que permita dar cuenta del fenómeno migratorio, de...

This study utilizes results from an agent-based simulation model to conduct public policy simulation of firms’ networking and cooperation in innovation. The simulation game investigates the differences in sector responses to internal and external changes, including cross-sector spillovers,...
