Is International Trade More Beneficial to Lower Income Economies? An Empirical Inquiry

Does the effect of international trade on income growth depend on the economy’s level of development? More specifically, is trade more beneficial to lower income economies? Does trade contribute to a smaller international income inequality? The present paper seeks to answer these questions by employing the empirical model of Frankel and Romer (1999 ), which shows trade increases income growth in a cross section of 150 countries. We find evidence in support of the hypothesis that international trade benefits the lower income economies more than it benefits the higher income economies. This finding is robust in the presence of control variables including distance from the equator and institutional quality.
