Trade and direct investment in producer services and the domestic market for expertise

Foreign producer services can provide substantial benefits for domestic firms. We build on earlier monopolistic-competition models of intermediate producer services in this paper. Results show that: (1) while foreign services are partial-equilibrium substitutes for domestic skilled labour, they may be general-equilibrium complements, (2) service trade can provide crucial missing inputs that reverse comparative advantage in final goods, (3) the 'optimal' tax on imported services may be a subsidy, and (4) in our dynamic formulation, there may be earnings losses for immobile workers along a transition path that suggest potentially important equity consequences of reform.
