Export-led Growth

Overview

Should exports be an important focus of economic growth strategies? The Washington Consensus, summarised by John Williamson some 35 years ago, would have answered in the negative. In the 1980s, when the consensus was forged, many countries had highly protective trade regimes, multiple exchange rates with large black-market premia, interest rate controls, and high inflation. The consensus was that if countries unified exchange rates, reduced barriers to trade, and brought inflation under control, exports would follow naturally. According to the Lerner symmetry theorem, import tariffs are equivalent to a tax on exports. Exchange controls act as an additional tax by forcing exporters to sell their earnings at an artificially appreciated exchange rate. If such policy-induced distortions were eliminated, the Washington Consensus suggested, exports would naturally reach their efficient level.

Today, many countries have unified their exchange rates, eliminated exchange controls, brought inflation to single digits, reduced trade barriers, and signed free trade agreements with many of their main trade partners, and yet, the median country has not narrowed its income gap with the United States. Export performance matters for growth, with countries that grow exhibiting more than proportional export growth. In many developing and emerging economies, growth is highly correlated with exogenous movements in their export prices and on fluctuations in international capital flows. Moreover, sustained fast-growing economies change the composition of their export basket substantially towards new, more complex products. 

Regional differences in growth and export trajectories confirm these observations. Countries in East Asia – including China — have managed rapid changes to their export baskets, increased their global export shares in new industries, and achieved fast growth. In Latin America, by contrast, even good performers like Chile, Colombia and Peru stabilised inflation, opened their economies to international trade (tariffs are negligible and they have signed numerous free trade agreements) and capital flows. Yet, they have been unable to diversify their export baskets and achieve sustained growth. The experiences of many nations in Africa and the Middle East resemble those of Latin America.

In this paper, I argue that a focus on exports, both at the intensive margin (where existing products increase their volume), but especially at the extensive margin (where new products start being exported), can help countries figure out what policies to adopt in order to achieve sustained growth. I present five stylised facts about growth and its trends in the decades that followed the Washington Consensus.
