In a commonvalueauction in which the information partitions of the bidders are connected, all rings are core … form, in spite of the underlying strategic externalities. A ring is core-stable if the core of this characteristic function … core-stable. …

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 …

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. …

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 …
