Chain stability in trading networks
Hatfield, John William; Kominers, Scott Duke; Nichifor, … - In: Theoretical economics : TE ; an open access journal in … 16 (2021) 1, pp. 197-234
In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to stability if all agents' preferences are jointly fully...

Multilateral matching
Hatfield, John William; Kominers, Scott Duke - In: Journal of Economic Theory 156 (2015) C, pp. 175-206
We introduce a matching model in which agents engage in joint ventures via multilateral contracts. This approach allows … us to consider production complementarities previously outside the scope of matching theory. We show analogues of the … equilibria exist, correspond to stable outcomes, and yield core outcomes. Competitive equilibria exist in our setting even when …

Chapter 16. Formation of Networks and Coalitions
Bloch, Francis; Dutta, Bhaskar - In: Handbook of social economics : volume 1, (pp. 729-779). 2011
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...

Overlapping coalitions, bargaining and networks
Agbaglah, Messan; Ehlers, Lars H. - 2010
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...

Information sharing and bargaining in buyer-seller networks
Priazhkina, Sofia; Page, Frank H. - 2016
This paper presents a model of strategic buyer-seller networks with information exchange between sellers. Prior to engaging in bargaining with buyers, sellers can share access to buyers for a negotiated transfer. We study how this information exchange affects overall market prices, volumes and...

Robust stability in matching markets
Kojima, Fuhito - In: Theoretical economics : TE ; an open access journal in … 6 (2011) 2, pp. 257-267
In a matching problem between students and schools, a mechanism is said to be robustly stable if it is stable, strategy …-proof, and immune to a combined manipulation, where a student first misreports her preferences and then blocks the matching that …
