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 either core stability or strict core stability is under...

On the nonemptiness of approximate cores of large games
Allouch, Nizar; Wooders, Myrna Holtz - 2014
We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...

An implementation approach to rotation programs
Korpela, Ville; Lombardi, Michele; Saulle, Riccardo D. - 2021
Rotation programs are widely used in societies. Some examples are job rotations, rotation schemes in the management of common-pool resources, and rotation procedures in fair division problems. We study rotation programs via the implementation of Pareto efficient social choice rules under...

An adaptation-mitigation game: does adaptation promote participation in international environmental agreements?
Borrero, Miguel; Rubio, Santiago J. - 2021
This paper studies how the investment in adaptation can influence the participation in an international environmental agreement (IEA) when countries decide in adaptation before they choose their levels of emissions. Two types of agreements are studied, a complete agreement for which countries...

Bargaining and power
Karos, Dominik - 2013
Given a simple game, a power configuration specifies the power of each player in each winning coalition. We introduce a new power configuration which takes into account bargaining among players in coalitions. We show that under very weak conditions on a bargaining solution there is a power...

Consider a voting procedure where countries, states, or districts comprising a union each elect representatives who … characterization of the efficient voting rule in terms of the weights assigned to different districts and the voting threshold (how … correlation structure of agents preferences, we analyze how voting weights relate to the population size of a country.

Mergers and Asset Prices in a Firm Network Economy
Brumen, Gorazd - Institut für Schweizerisches Bankwesen <Zürich> - 2007
We examine merger activity and its effect on asset pricing in a firm network economy. Mergers create internal capital markets which change the cash flow risk structure of the merging firms. We propose a solution concept for coalitional games without the superadditivity axiom, which extends...

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...
