Core-stable rings in second price auctions with common values
Forges, Françoise; Orzach, Ram - 2010
In a common value auction in which the information partitions of the bidders are connected, all rings are core-stable. More precisely, the ex ante expected utilities of rings, at the (noncooperative) sophisticated equilibrium proposed by Einy, Haimanko, Orzach and Sela (Journal of Mathematical...

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...

The paradox of new members in the EU Council of Ministers : a non-cooperative bargaining analysis
Montero, María - 2010 - This version: September 2010
Power indices suggest that adding new members to a voting body may increase the power of an existing member, even if the number of votes of all existing members and the decision rule remain constant. This phenomenon is known as the paradox of new members. This paper uses the leading model of...

Computational complexity in additive hedonic games
Dimitrov, Dinko; Sung, Shao Chin - 2008
We investigate the computational complexity of several decision problems in hedonic coalition formation games and … demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when …. -- Additive Preferences ; Coalition Formation ; Computational Complexity ; Hedonic Games ; NP-hard ; NP-complete …

Stationary consistent equilibrium coalition structures constitute the recursive core
Kóczy, László Á. - 2009
We study coalitional games where the proceeds from cooperation depend on the entire coalition structure. The coalition … structure core (Kóczy, 2007) is a generalisation of the coalition structure core for such games. We introduce a noncooperative … extend past results to games that are not totally balanced (understood in this special setting) we introduce subgame …

Finding maxmin allocations in cooperative and competitive fair division
Dall'Aglio, Marco; Di Luca, Camilla - 2011
We consider upper and lower bounds for maxmin allocations of a completely divisible good in both competitive and cooperative strategic contexts. We then derive a subgradient algorithm to compute the exact value up to any fixed degree of precision. -- Fair Division ; Maxmin Allocation ; Kalai...

Equilibrium and matching under price controls
Herings, Peter Jean-Jacques - 2015
The paper considers a one-to-one matching with contracts model in the presence of price controls. This set-up contains two important streams in the matching literature, those with and those without monetary transfers, as special cases and allows for intermediate cases with some restrictions on...

The evolution of core stability in decentralized matching markets
Nax, Heinrich H.; Pradelski, Bary S. R.; Young, H. Peyton - 2013
Decentralized matching markets on the internet allow large numbers of agents to interact anonymously at virtually no cost. Very little information is available to market participants and trade takes place at many different prices simultaneously. We propose a decentralized, completely uncoupled...
