We study two n-player sequential network formation games with externalities. Link formation is tied to simultaneous transfer selection in a Nash demand like game in each period. Players in groups can counterpropose. We give necessary and sufficient conditions for efficiency in terms of cyclical...

The present study focusses on analyzing the migration patterns in Colombia from a network theory perspective. The analysis is divided in two parts. First a model based on Network Theory that takes into account the migration process, has its most prevalent features, and gives a framework for the...

In many contexts an individual's beliefs and behavior are affected by the choices of his or her social or geographic neighbors. This influence results in local correlation in people's actions, which in turn affects how information and behaviors spread. Previously developed frameworks capture...

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...

Situations that require individuals to mutually cooperate are often analysed as coordination games. This paper proposes a model of cooperative network formation where the network is formed through the process of the coordination game being played between multiple agents. Additionally, network...

We introduce a new network centrality measure founded on the Gately value for cooperative games with transferable utilities. A directed network is interpreted as representing control or authority relations between players-constituting a hierarchical network. The power distribution embedded...

In all social and economic interactions, individuals or coalitions choose not only with whom to interact but how to interact, and over time both the structure (the “with whom”) and the strategy (“the how”) of interactions change. Our objectives here are to model the structure and...
