The future of economic convergence

TLDR: The question addressed in this article is whether the gap in performance between the developed and developing worlds can continue, and in particular, whether developing nations can sustain the rapid growth they have experienced of late.

Abstract: The question addressed in this paper is whether the gap in performance between the developed and developing worlds can continue, and in particular, whether developing nations can sustain the rapid growth they have experienced of late. The good news is that growth in the developing world should depend not on growth in the advanced economies themselves, but on the difference in the productivity levels of the two groups of countries - on the "convergence gap" - which remains quite large. Yet much of this convergence potential is likely to go to waste. Convergence is anything but automatic, and depends on sustaining rapid structural change in the direction of tradables such as manufacturing and modern services. The policies that successful countries have used to achieve this are hard to emulate. Moreover, these policies - such as currency undervaluation and industrial policies - will meet greater resistance on the part of industrial countries struggling with stagnant economies and high unemployment.
