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 …

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

convex-valued. I use the corresponding consistency property and its converse to axiomatize the inner core for games that are …

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 …

This paper first establishes a new core theorem using the concept of generated payoffs: the TU (transferable utility …) core is empty if and only if the maximum of generated payoffs (mgp) is greater than the grand coalition's payoff v(N), or …
