product differentiation and link costs: (i) the non-exclusive distribution and non-exclusive dealing network in which both … exclusive distribution and exclusive dealing network in which each retailer distributes a different product is stable for low … degrees of product differentiation; (iii) the mixed distribution network in which one retailer distributes both products while …

network is always pairwise stable and the partially connected network is stable if and only if spillovers are large enough. If … spillovers are small, the complete network is the efficient network; otherwise, the efficient network is the partially connected … network. Thus, a conflict between stability and efficiency may occur: efficient networks are pairwise stable, but the reverse …

We study a model in which heterogeneous agents first form a trading network where link formation is costless. Then, a … a trading network is pairwise stable if and only if it is a core periphery network where the core consists of all weak …

We define the notion of coalitional network to represent a network and a coalition structure, where … the network specifies the nature of the relationship each individual has with his coalition members and with individuals … contractual stability which requires that any change made to the coalitional network needs the consent of both the deviating …

Thus, any network outside the 1/2 -pairwise stable set must be considered as a non-robust network. We also … show that the 1/2 -pairwise stable set can contain no pairwise stable network and we provide examples where a set of …
