Wake up and smell the ginseng: International trade and the rise of incremental innovation in low-wage countries

Increasingly, a small number of low-wage countries such as China and India are involved in incremental innovation. That is, they are responsible for resolving production line bugs and suggesting product improvements. We provide evidence of this new phenomenon and develop a model in which there is a transition from old style product cycle trade to trade involving incremental innovation in low-wage countries. The model explains why levels of involvement in incremental innovation vary across low-wage countries and across firms within each low-wage country. We draw out implications for sectoral earnings, living standards, the capital account and, foremost, international trade in goods.
