incentive compatibility constraints: the associated ex ante core is generically non-empty. However, we exhibit a wellbehaved … exchange economy in which this core is empty, even if goods are allocated through random mechanisms. …

This paper provides a general overview of the literature on the core of an exchange economy with asymetric information …. Incentive compatibility is emphasized in studying core concepts at the ex ante and the interim stage.The analysis includes … issues of non emptiness of the core as wellas core convergence to price equilibrium allocations. …

We show that in large finite economies, core allocations can be approximately decentralized as Nash (rather than Walras …) equilibrium. We argue that this excrcise is an essential complement to asymptotic core equivalence results, because it implies … precisely the interpretation of asymptotic core convergence, namely the emergence of price taking. …
