Coalitional Approaches to Collusive Agreements in Oligopoly Games.
Currarini, Sergio; Marini, Marco - Facoltà di Economia, Università degli Studi di Urbino - 2011
In this paper we review a number of coalitional solution concepts for the analysis of the stability of cartels and … the basic problem of the stability of the whole industry association of firms under oligopoly and, for this purpose, we … consider the stability of associations of firms organized in coalition structures different from the grand coalition. To this …

Coalitional Approaches to Collusive Agreements in Oligopoly Games
Currarini, Sergio; Marini, Marco A. - Dipartimento di Ingegneria Informatica, Automatica e … - 2013
In this paper we review a number of coalitional solution concepts for the analysis of cartel and merger stability in … problem of the stability of the whole industry association of firms under oligopoly and, for this purpose, we introduce the … coalitions of firms yield very different results on the set of allocations which are core-stable. We then consider the stability …

Coalitional matchings
Dimitrov, Dinko; Lazarova, Emiliya - 2008
A coalitional matching is a two-sided matching problem in which agents on each side of the market may form coalitions such as student groups and research teams who - when matched - form universities. We assume that each researcher has preferences over the research teams he would like to work in...

Status-seeking in hedonic games with heterogeneous players
Lazarova, Emiliya; Dimitrov, Dinko - 2010
We study hedonic games with heterogeneous player types that reflect her nationality, ethnic background, or skill type. Agents' preferences are dictated by status-seeking where status can be either local or global. The two dimensions of status define the two components of a generalized constant...

Many-to-one matching: Externalities and stability
Salgado, Alfredo - 2020
In this paper, we establish sufficient conditions on the domain of preferences and agents' behavior in order to characterize the existence of stable assignments in many-to-one matching problems with externalities. The set of stable matchings depends on what agents believe other agents will do if...

Coalitional Matchings
Dimitrov, Dinko; Lazarova, Emiliya - Fondazione ENI Enrico Mattei (FEEM) - 2008
A coalitional matching is a two-sided matching problem in which agents on each side of the market may form coalitions such as student groups and research teams who - when matched - form universities. We assume that each researcher has preferences over the research teams he would like to work in...

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 first and second welfare theorems and, when agents'...

Some properties of the core on convex geometries
Okamoto, Yoshio - In: Computational Statistics 56 (2003) 3, pp. 377-386
A game on a convex geometry was introduced by Bilbao as a model of partial cooperation. We investigate some properties of the core of a game on a convex geometry. First, we show that if a game is quasi-convex, then the core is stable. This result can be seen as an extension of a result by...

New characterizations for largeness of the core
Estévez-Fernández, Arantza - In: Games and Economic Behavior 76 (2012) 1, pp. 160-180
characterizations, we show the equivalence between largeness of the core and stability of the core for games with at most 5 players. …
