Obviously, the critical share depends on the shape of the demand function and that of each ﬁrm’s cost function. In order to get some numerical values for the critical share, we assume a linear demand curve and constant marginal costs which may differ among ﬁrms. As we shall ﬁnd out in the following analysis, the critical share is surprisingly high. 12) and that the total cost for ﬁrm i is given by c i = γi xi . 4), and rearranging the terms, we get xi = 6 α − γi − β D . 14) It is well known that promoting output by a monopoly ﬁrm by using subsidies increases total surplus.
The ﬁrms are assumed to play Cournot-Nash games in both stages, and we consider the subgame perfect equilibrium of the two-stage game. 1) where ki represents ﬁrm i ’s primary marginal cost which does not depend on R&D investment, and hi represents ﬁrm i ’s R&D investment. Primary-cost differentials may be due to some ﬁrm-speciﬁc knowledge or access to special resources, such as locations, raw materials and imported technologies, which may be caused by discriminatory regulations. It is to be noted that we consider only a special case of a more general speciﬁcation of the costs given by c i = Hi (ki , hi ).
4 are still valid even in the case of foreign penetration through both trade and direct investment. The domestic government is assumed to restrict the capacity of supply by the foreign subsidiary ﬁrm in order to protect domestic ﬁrms from the foreign penetration. Under perfect competition in the domestic market, such a quantitative restriction decreases domestic total surplus. The loss in domestic surplus is simply considered to be the costs for protecting domestic ﬁrms. However, in this chapter we ﬁnd that the restriction against foreign penetration may increase domestic total surplus if the domestic market is oligopolistic.
