Growing through trade in intermediate goods: the role of foreign growth and domestic tariffs

We show that pure Ricardian trade can account for the empirical evidence that domestic growth is more affected by foreign growth than by trade openness. To do this, we develop a two-country model involving a backward economy that exchanges intermediate goods with a faster growing country. We obtain three main results regarding growth and welfare of the backward economy: (i) the growth-enhancing comparative advantage is facilitated by faster foreign growth; (ii) the growth rate may be negatively affected or unaffected by a domestic tariff, while it is always positively impacted by foreign growth; and (iii) a domestic tariff could be welfare-improving.
