In this paper we analyze the effects of mergers on welfare of a host foreign direct investment country. Using a partial equilibrium model with imperfect competition, domestic and foreign firms compete among them producing differentiated goods. The domestic government sets discriminatory subsidies between domestic and foreign firms. As a first result, the optimal subsidy applied to foreign firms is negative affecting the consumer and producer surplus, as well as the revenue/expense policy.

When domestic firms merge as a response to foreign competition, in order to obtain competitive advantage, the effect on welfare is ambiguous. In the case of a negative impact of merger, the government subsidizes foreign firms. Finally, with a higher level of differentiation the domestic welfare increases, in his sense the consumers preferences are relevant.
