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. …

This paper provides a noncooperative approach to core stability in an economy with incomplete information. The analysis … covers general exchange economies, although our tightest results hold when effective coalitions consist of at most two … Serrano and Vohra (1997) to implement the core of a complete information economy. This leads to a version of the core that we …

We analyze the ex ante incentive compatible core for replicated private information economies. We show that any … allocation in the core when the economy is replicated sufficiently often is approximately Walrasian for the associated Arrow …

, including theorems guaranteeing that the core is nonempty. Then the basic pure exchange economy is extended to include … asymmetric information. The possibilities for such models to generate cooperative games are examined. Here the core is emphasized …
