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

compability 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. …

An appropriate (interim) notion of the core for an economy with incomplete information depends on the amount of … information that coalitions can share. The coarse and fine core, as originally defined by Wilson (1978), correspond to two polar … cases, involving no information sharing and arbitrary information sharing, respectively. We propose a new core notion, the …

An appropriate (interim) notion of the core for an economy with incomplete information depends on the amount of … information that coalitions can share. The coarse and fine core, as originally defined by Wilson (1978), correspond to two polar … credible core, which incorporates incentive compatibility constraints, and is based on the idea that a coalition can coordinate …

A core allocation of a complete information economy can be characterized as one that would not be unanimously rejected … of such voting games, this approach makes it possible to derive core concepts in which the transmission of information … among members of a coalition is endogenous. Our results lend support to the credible core of Dutta and Vohra (2003) and the …
