A disparate literature hypothesizes what can broadly be described as the common‐enemy
effect: the fact that the interaction with a common enemy (formed by Nature, an individual, or …

The organization of agents into networks plays an important role in the determination of the
outcome of many social and economic interactions. Networks of relationships help …

We study the formation of R&D networks when firms can be either myopic or farsighted.
Stability leads to R&D networks consisting of either asymmetric components or nearly …

We introduce the concept of a horizon-K farsighted set to study the influence of the degree of
farsightedness on network stability. The concept generalizes existing concepts where all …

I develop two related solution concepts—equilibrium coalitional behavior and credible
equilibrium coalitional behavior—that capture foresight and impose the requirement that …

Social psychology studies the “common enemy effect”, the phenomenon that members of a
group work together when they face an opponent, although they otherwise have little in …

We adopt the notion of myopic-farsighted stable set to study the stability of networks when
myopic and farsighted individuals decide with whom they want to form a link, according to …

In this paper we study a model of weighted network formation. The bilateral interaction is
modeled as a Tullock contest game with the possibility of a draw. We describe stable …

We test the performance of myopic and farsighted stability concepts in a network formation
experiment with a stream of payoffs and relatively unstructured link formation process. A …

We consider a model of friendship network formation based on de Marti and Zenou (2017)
where individuals belong to two different communities and costs of forming links depend on …
