Reference work entry


The core of an economy consists of those states of the economy which no group of agents can ‘improve upon’. The core is a rather theoretical fundamental equilibrium concept. Indeed, the core provides a theoretical foundation of a more operational equilibrium concept, namely, the competitive equilibrium, which is a very different notion of equilibrium.
