The concept of 'the core' originates in cooperative game theory and its introduction to economics in the 1960s as a … questions in economics. Discovery of the core was met with enthusiasm among the community of economic theorists at the time …. However, use of the core eventually waned and the concept faded into the backdrop of economic theory. This paper makes use of …

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on … transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff … vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows …

definition includes as a particular case the classical definition of pure exchange economy. We adapt the core concept to a … coalitional exchange economy, and we show the non-emptiness of the core. Finally, we discuss more general setting where individual …

, we prove the non-emptiness of the fuzzy rejective core. Then, via Konovalov (1998, 2005)'s equivalence result, we solve …

strong sequential core of such an economy consists of those consumption processes where no coalition of agents wishes to … sufficient conditions for non-emptiness of the strong sequential core in stationary economies are derived, based on non …. Moreover, sufficient conditions are given under which the strong sequential core contains only time and history independent …

It is shown that core-Walras equivalence fails whenever the commodity space is a non-separable Banach space. The … interpretation is that a large number of agents guarantees core-Walras equivalence only if there is actually a large number of agents … extremely dispersed, so that the standard theory of perfect competition fails.
