The paper studies, in a repeated interaction setting, how the presence of cooperative agents in a heterogeneous community organized in groups, affects group efficiency and stability. The paper extends the literature by assuming that each type can profitably mimic other types. It is shown that such enlargement of profitable options prevents group stabilization in the single group case. Stabilization can be obtained with many groups, but its driver is not the efficiency gain due to the presence of cooperative individuals. Instead stabilization is the result of free riding opportunities.
