Abstract

The paper illustrates a new methodology for deriving the feasibility constraints of the core and the aspiration core, a non-empty core-extension, from other axioms. The two solution concepts differ only in the implicit rules that govern coalition formation. Our characterizations derive those different rules from familiar axioms.
