over consumption goods, competitive equilibrium allocations exist and belong to the (ex ante incentive) core. Furthermore …, any competitive equilibrium allocation can be viewed as an element of the core of the n-fold replicated economy, for every …

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

This paper characterizes the core of a differentiable convex distortion of a probability measure on a nonatomic space … dominance. The densities that have the same distribution as the derivative of the distortion are the extreme points of the core …

We identify particular exchange economies with asymmetric information in which the ex ante incentive compatible core is … restriction to a specific class of economies are crucial for the result. Indeed, the ex ante incentive compatible core can be …
