Our paper aims at examining whether the market dominance occurs endogenously and whether multimarket contact increases sustainability of collusion in the case of market dominance by introducing R & D activity into the familiar quantity-setting duopolistic repeated game. We establish the following results: (1) both firms always pay R & D expenditures when the level of R & D cost is low. (2) The reciprocal market dominance as well as the nonreciprocal one occur when the level of R & D cost is moderate. (3) Multimarket contact does not reduce the sustainability of collusion.
