It is generally believed that trade liberalization can impede technology transfers from abroad. By considering R&D behavior of the foreign firm, this paper shows contrarily that trade liberalization has a positive effect on the foreign firm's R&D, resulting in a better technology to be transferred to the domestic firm and enhancing both the domestic and the world welfare. This result holds for trade liberalization in terms of not only tariff barriers but also non-tariff barriers such as quotas. By comparing the technology transfers between the tariff and the quota regimes, we also find that when the trade barrier is small (large), a tariff policy is superior (inferior) to the equivalent quota policy in acquiring superior technologies. Finally, a ban on technology export by the foreign country may surprisingly induce the foreign firm to invest more on its R&D. |
