The ex ante incentive compatible core of an exchange economy with private information is the (standard) core of a … incentive compatible core can be empty, even if utility functions are quasi-linear. If, in addition to quasi-linearity, further … assumptions are made (like independent private values), the non-emptiness of the core follows nevertheless from d?Aspremont and …

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 … credible core, which incorporates incentive compatibility constraints, and is based on the idea that a coalition can coordinate …
