Computational Complexity in Additive Hedonic Games
Sung, Shao-Chin; Dimitrov, Dinko - 2009
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...

Multiple Membership and Federal Sructures
Savvateev, Alexei V. - 2008
We consider a model of the world with several regions that may create a unified entity or be partitioned into several unions (countries). The regions have distinct preferences over policies chosen in the country to which they belong and equally share the cost of public policies. It is known that...

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...

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...

Equilibrium and Matching Under Price Controls
Herings, P. Jean-Jacques - 2015
(1986) as special cases. The paper presents a notion of competitive equilibrium, called Drèze equilibrium, for this class of … controls. It is shown that Drèze equilibrium allocations are equivalent to allocations induced by stable outcomes. One … implication is the existence of Drèze equilibria. Another implication is the equivalence of a competitive equilibrium concept and …

Von Neumann-Morgenstern Farsightedly Stable Sets in Two-Sided Matching
Vannetelbosch, Vincent J.; Mauleon, Ana; Vergote, Wouter - 2008
We adopt the notion of von Neumann-Morgenstern farsightedly stable sets to predict which matchings are possibly stable when agents are farsighted in one-to-one matching problems. We provide the characterization of von Neumann-Morgenstern farsightedly stable sets: a set of matchings is a von...

Networks with Group Counterproposals
Nieva, Ricardo - 2008
We study two n-player sequential network formation games with externalities. Link formation is tied to simultaneous transfer selection in a Nash demand like game in each period. Players in groups can counterpropose. We give necessary and sufficient conditions for efficiency in terms of cyclical...
