The co-author model is introduced by Jackson and Wolinsky (1996, Journal of Economic Theory) as a typical example of the models of network formation. In this note, we study which network is pairwise stable and/or stochastically stable when the number of players is four.

Goyal and Joshi (2006, Int Econ Review) apply the notion of ``pairwise stable networks" introduced by Jackson and Wolinsky (1996, J Econ Theory) to a model of free trade network formation, and show that (i) every pairwise stable network is either complete or almost complete (with all countries...

Jackson and Watts (2002, J Econ Theory) study a dynamic process of network formation assuming that each player is myopic. In this note, we study the same dynamic process but assume that each player is farsighted. In particular, we consider a finite-horizon version of such a dynamic process in a...

So-called “search equilibrium models” typically have multiple equilibria. In almost all studies on these models, only steady states are considered mainly because it is difficult to find non-stationary equilibria. This difficulty does not disappear even if we consider finite-horizon...
