We consider a simple multi‐period model where the entry cost varies with respect to the number of firms that have entered previously. In the non‐cooperative outcome, there is clustered entry among the firms in the last period; hence, the full potential of learning is not expropriated. When firms are allowed to form coalitions, the non‐cooperative outcome is dominated; thus, there is a gain in efficiency. We also find that full efficiency is obtained when a grand coalition is formed. The implications of policies on coalitions as well as on individual firms are also discussed.
