We analyze coalition formation with heterogeneous agents based on an individual stability concept. Defining exchanging and refractory agents, we give existence and enlargement conditions for coalitions with heterogeneous agents. Using the concept of exchanging agents we give necessary conditions for internal stability and show that refraction is a sufficient condition for the failure of an enlargement of the coalition.
