## Abstract

A cost-reducing innovation is available to Cournot duopolists through licensing. The firms are *ex ante* heterogeneous and adoption of the innovation impacts them differently.
Is it possible for the inefficient duopolist to catch up with its efficient rival? Under certain conditions, yes. The conditions, however, are stringent: It is not sufficient, for instance, that the innovation promotes a change in the efficiency rank of the firms.
