We develop a partial equilibrium model of foreign direct investment (FDI) in which identical foreign firms locate themselves in a host country to compete in an oligopolistic market for a non-tradeable commodity. The host country, assumed to be small in the market for FDI, makes use of two instruments, viz., a profit tax and a local content requirement, to compete for FDI in the international market. We assume the existence of unemployment in the host country. The structure of optimal instruments and their relationship to the number, and the relative efficiency levels, of the domestic firms, are established
