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. …

The … core is nonempty when coalition feasible sets are monotonic and players' preferences over public goods satisfy a condition … called cardinal connectedness. Moreover, a core allocation consists of connected coalitions …

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 …

We then … demonstrate that the equal treatment core coincides with the set of price-taking equilibrium outcomes with anonymous prices - that … nonemptiness of the core and equivalence of the core to the set of equilibrium outcomes. Our approach provides a new technique for …

in the coalition. Unlike in the MCST model we show that the core of the induced cost game in the MCCN model can be empty … (without introducing Steiner nodes). We therefore consider sufficient conditions for non-empty core. Theorem 1 shows that when … the efficient network and the demand graph consist of the same components, the induced cost game has non-empty core …

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 approximated by equal-treatment e-cores of the games themselves. Our proof …

This paper develops a model of an economy with clubs where individuals may belong to multiple clubs and where there may … be ever increasing returns to club size. Clubs may be large, as large as the total agent set. The main condition required … is that sufficient wealth can compensate for memberships in larger and larger clubs. Notions of price taking equilibrium …
