Trade policy, export expansion, human capital and growth

This paper empirically investigates the impact of trade policy on export expansion and on GDP growth in developing countries while controlling for the human capital stock and the initial level of development. By using a simultaneous system estimation we unite the approach found in the export expansion and growth literature with the approach found in papers that estimate the effect of trade policy on growth, while also making several improvements in the estimation of the underlying relationships. The results obtained from our estimation are more credible because of these improvements and therefore have stronger policy implications. We find that outward-oriented trade policies substantially and significantly impact growth in developing countries not only by directly enhancing exports but also through a feedback (or multiplier) effect.
