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 …

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. …

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 …

This is important for applications … since it reduces the amount of information that agents have to reveal about their preference relations to centralized Core …

We extend Jackson and Watts's (2002) result on the coincidence of S-stochastically stable and core stable networks from … marriage problems to roommate problems. In particular, we show that the existence of a side-optimal core stable network, on …
