Why Exports Matter

Does what economies export matter for development? If so, can industrial policies improve on the export basket generated by the market? This book approaches these questions from a variety of conceptual and policy viewpoints. Reviewing the theoretical arguments in favor of industrial policies, the authors first ask whether existing indicators allow policy makers to identify growth-promoting sectors with confidence. To this end, they assess, and ultimately cast doubt upon, the reliability of many popular indicators advocated by proponents of industrial policy. Second, and central to their critique, the authors document extraordinary differences in the performance of countries exporting seemingly identical products, be they natural resources or 'high-tech' goods. Further, they argue that globalization has so fragmented the production process that even talking about exported goods as opposed to tasks may be misleading. Reviewing evidence from history and from around the world, the authors conclude that policy makers should focus less on what is produced, and more on how it is produced. They analyze alternative approaches to picking winners but conclude by favoring 'horizontal-ish' policies--for instance, those that build human capital or foment innovation in existing and future products that only incidentally favor some sectors over others.

The second part of this two-part study documents the superior performance of export plants and firms, as well as their workers in all skill categories, relying on data from 1992 through 1995. Among new findings are stronger and more stable employment growth for exporters.

This study appears in two parts, both of which are featured in this set. The authors assess questions such as whether export commitments cause superior performance or whetehr the two factors are merely correlated, and whether imports and outsourcing are offset to the findings about exports.

How do countries enhance their exports of goods in a largely tariff-free environment? Our investigation of export performance of new member states in the European Union single market, which provides a natural control for barrier-free environment, points to the importance of structural reforms, particularly in the areas of higher education, skills upgrade, wage structure’s ability to provide incentives to work and foreign investment environment. In addition, establishing links with supply chains, which in addition to the above-mentioned reforms also depend on better institutions and infrastructure, are important. The analysis in the paper shows that new member states are at varying levels of quality and integration, which highlights the need for country-specific policy priorities. Services trade, which is subject to significant non-tariff barriers in the EU market even after the implementation of the Services Directive, shows considerable room for growth given the comparative advantage of some of the new member states.

This paper examines whether the type of commodity dominating a country’s exports matters for export concentration. Using a dataset covering 173 countries, including 87 commodity-dependent developing countries, we estimate dynamic panel data models that control for a large set of determinants of export concentration. We find that GDP shares of energy exports and, to a lesser extent, GDP shares of minerals, are important determinants of export concentration. Our results imply that developing countries that are dependent on energy or minerals sectors face challenges that are different from those faced by countries dependent on the export of agriculture and manufacturing products. Economic and export diversification policies need to take these differences into account.

This paper focuses on the sluggish growth of world trade relative to income growth in recent years. The analysis uses an empirical strategy based on an error correction model to assess whether the global trade slowdown is structural or cyclical. An estimate of the relationship between trade and income in the past four decades reveals that the long-term trade elasticity rose sharply in the 1990s, but declined significantly in the 2000s even before the global financial crisis. These results suggest that trade is growing slowly not only because of slow growth of Gross Domestic Product (GDP), but also because of a structural change in the trade-GDP relationship in recent years. The available evidence suggests that the explanation may lie in the slowing pace of international vertical specialization rather than increasing protection or the changing composition of trade and GDP.

When local cost discovery generates knowledge spillovers, specialization patterns become partly indeterminate and the mix of goods that a country produces may have important implications for economic growth. We demonstrate this proposition formally and adduce some empirical support for it. We construct an index of the "income level of a country's exports," document its properties, and show that it predicts subsequent economic growth.
