In this paper it is shown that the core and the bargaining sets of Davis-Maschler and Zhou coincide in a class of …

This paper deals with a core-equilibrium equivalence in an economy with public goods where preferences of consumers …

. The core predicts a unique and extreme outcome: the entire surplus is split evenly among the buyers when m > n and among … the sellers when m < n; the long side gets nothing. We test this core conjecture in the lab with n + m = 3 or 5 randomly … agreements while trading. Despite frequent attempts to collude and occasional large deviations from the core prediction, we find …

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 …
