This paper studies a new refinement for Perfect Bayesian equilibrium, Bayesian equilibrium by iterative conjectures (BEIC). BEIC requires players to make predictions, starting from first order uninformative predictive distribution functions (or conjectures) and keep updating with statistical...

I present a behavioural model of network formation with positive network externalities in which individuals have preferences for being part of a clique. The behavioural model leads to an associated supermodular (Topkis, 1979) normal form game. I show that the behavioural model converges to the...

I look at the equilibrium effects of homophily in network formation games having positive externalities. I show that very weak preferences for network effects (such as preference for being part of a clique) may result in very high levels of homophily at equilibrium. I present an empirical...

In this paper the extended model of Minority game (MG), incorporating variable number of agents and therefore called Grand Canonical, is used for prediction. We proved that the best MG-based predictor is constituted by a tremendously degenerated system, when only one agent is involved. The...
