This paper investigates the effects of changes in retail market concentration when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between upstream and downstream firms which allows for general forms of demand and retail competition. Whether...

This Supplemental Material includes, among other things, the analytical derivatives of the price-cost margins of manufacturers determined via the "Nash-in-Nash" bargaining solution, the computation of the out-of-equilibrium retail prices following a bargaining breakdown, the algorithm used to...

This chapter surveys a sizable and growing literature on coalition formation. We refer to theories in which one or more groups of agents (“coalitions”) deliberately get together to jointly determine within-group actions, while interacting noncooperatively across groups. The chapter describes...

This chapter surveys recent models of coalition and network formation in a unified framework. Comparisons are drawn among various procedures of network and coalition formation, involving simultaneous and sequential moves. The survey also covers models of group and network formation by farsighted...

Pairing Games or Markets studied here are the non-two-sided NTU generalization of assignment games. We show that the Equilibrium Set is nonempty, that it is the set of stable allocations or the set of semistable allocations, and that it has several notable structural properties. We also...

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....
