This paper considers a communication network characterized by an endogenous architecture and an imperfect transmission … of information as in Bala and Goyal (2000). We propose a similar network's model with the difference that it is … dominant. Differently from other models, where the network represents only a channel to obtain information or to play a game …

The delay in receiving this information requires the players to be more patient to sustain the … same level of cooperation as in a complete network, although a Folk Theorem obtains when the players are patient enough …

In this paper we study the effects of institutional constraints on stability, efficiency and network formation.

Based on this two-ingredient model, network and societal cover, we examine the impact of societal …
