The equivalence of markets and games concerns the relationship between two sorts of structures that appear … fundamentally different -- markets and games. Shapley and Shubik (1969) demonstrates that: (1) games derived from markets with … concave utility functions generate totally balanced games where the players in the game are the participants in the economy …

This paper provides sufficient conditions to ensure nonemptiness of approximate cores of many-player games and symmetry … of approximate core payoffs (the equal treatment property). The conditions are: (a) essential superadditivity -- an ….e., per capita) payoffs of large populations; thus, SGN is a analogue, for games with a finite player set, of the condition …

effect, the core is nonempty when coalition feasible sets are monotonic and players' preferences over public goods have … connected support. All core allocations consist of connected coalitions and they are Tiebout equilibria as well. We also examine … the no-exodus equilibrium for games whose feasible sets are not monotonic. …

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 consideration, the existence problem of a stable coalition structure …

The conflict between pro-self and pro-social behaviour is at the core of many key problems of our time, as, for example … impact on pro-sociality. In Studies 1-4 (total N = 1,400), we use economic games to demonstrate that asking subjects to self …
