In particular we show that it is an inhomogeneous … sacrifice') which is derived from the egalitarian-equivalent concept suggested by Moulin (1987). We also develop a simple core … test by which it can be checked whether a given allocation is in the core thus being a possible outcome of a cooperative …

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 reinterprets the ? -core (Chander and Tulkens (1995, 1997)) and justifies it as well as its prediction that … by a coalition, the nonmembers will have incentives to break apart into singletons, as is assumed in the definition of …

We generalise the coalition structure core to partition function games. Our definition relies only on one crucial … initial one, and –whenever this is possible– they come to a residual core outcome. Deviating players form their optimistic or … pessimistic expectations with this in mind. This leads to a recursive definition of the core. When compared to existing approaches …

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 …
