The core and competitive equilibria of a large exchange economy on the commodity space ℓ∞ will be discussed. We define the economy as a measure on the space of consumers’ characteristics following Hart and Kohlberg (1974), and prove the existence of competitive equilibria and their...

Mostly infinite dimensional economies can be considered limits of finite dimensional economies, in particular when we think of time or product differentiation. We investigate conditions under which sequences of quasi-equilibria in finite dimensional economies converge to a quasi-equilibrium in...

Mostly infinite dimensional economies can be considered limits offinite dimensional economies, in particular when we think of time orproduct differentiation. We investigate conditions under which sequences of quasi-equilibria in finite dimensional economies converge to a quasi-equilibrium in the...
