Given a standard myopic process in a coalition formation game, an absorbing set is a minimal collection of coalition structures that is never left once entered through this process. Absorbing sets are an important solution concept in coalition formation games, but they have drawbacks: they can be large and hard to obtain. In this paper, we characterize an absorbing set in terms of a collection consisting of a small number of sets of coalitions that we refer to as a “reduced form” of a game. We apply our characterization to study convergence to stability in several economic environments.
