Dynamic Comparative Advantage and the Welfare Effects of Trade
Preprint
- preprint Published in RePEc
Abstract
This paper argues that developing economies may face a trade-off between specializaing according to existing comparative advantage (in low-technology goods), and entering sectors in which they currently lack a comparative advantage, but may acquire such an advantage in the future as a result of the potential for productivity growth (in high-technology goods). Comparative advantage is endogenously determined by past technological change, while simultaneously shaping current rates of innovation.Keywords
