We analyse a two period model of the interbank market, i.e. the market at which banks trade liquidity. We assume that banks do not take the interbank interest rate as given, but multilaterally negotiate on interest rates and transaction volumes. The solution concept applied is the Shapley value....

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect...

This paper investigates stable and efficient networks in the context of risk sharing, when it is costly to establish and maintain relationships that facilitate risk sharing. We find a novel trade-off between efficiency and equality: The most stable efficient networks also generate the most...

We introduce a noncooperative multilateral bargaining model for a network-restricted environment, in which players can communicate only with their neighbors. Each player strategically chooses the bargaining partners among the neighbors to buy out their communication links with upfront transfers....
