This compelling two-volume collection presents the major literary contributions to the economic analysis of the consequences of trade liberalization on growth, productivity, labor market outcomes and economic inequality. Examining the classical theories that stress gains from trade stemming from comparative advantage, the selection also comprises more recent theories of imperfect competition, where any potential gains from trade can stem from competitive effects or the international transmission of knowledge. Empirical contributions provide evidence regarding the explanatory power of these various theories, including work on the effects of trade openness on economic growth, wages, and income inequality, as well as evidence on the effects of trade on firm productivity, entry and exit. Prefaced by an original introduction from the editor, the collection will to be an invaluable research resource for academics, practitioners and those drawn to this fascinating topic.
This article presents evidence on the positive effect of international trade on productivity growth using industrial level data preceding and following Brazil's trade liberalization in 1988-90. Our data reveal large and widespread productivity improvement across industries after barriers to trade were drastically reduced. Econometric results confirm the association between trade liberalization and productivity growth and show that the impact was indeed substantial: The observed tariff reduction in the period brought a 6% estimated increase in total factor productivity growth rate and a similar impact on labor productivity.
This paper reassesses the impact of trade liberalization on productivity. We build a new, unique database of effective tariff rates at the country-industry level for a broad range of countries over the past two decades. We then explore both the direct effect of liberalization in the sector considered, as well as its indirect impact in downstream industries via input linkages. Our findings point to a dominant role of the indirect input market channel in fostering productivity gains. A 1 percentage point decline in input tariffs is estimated to increase total factor productivity by about 2 percent in the sector considered. For advanced economies, the implied potential productivity gains from fully eliminating remaining tariffs are estimated at around 1 percent, on average, which do not factor in the presumably larger gains from removing existing non-tariff barriers. Finally, we find strong evidence of complementarities between trade and FDI liberalization in boosting productivity. This calls for a broad liberalization agenda that cuts across different areas.
Openness to trade is a key element of economic policy; continuing extreme poverty in developing countries is a disgrace. This Handbook examines how concerns about the world's poor should affect our attitude towards trade liberalization. Part I draws on economic analysis and practical experience to construct a framework to analyse the links between trade liberalization and poverty. It shows policy-makers how to identify the critical features in their economies so they can ensure that the poor benefit from liberalization. Part II explores the reform of particular sectors -- agriculture, services, etc., and particular instruments of trade policy -- export subsidies, anti-dumping measures, etc. It presents an economic analysis of each type of reform, shows the likely outcome for the poor, and discusses the issue's status on the World Trade Organization's agenda.

Manufacturing is intensive in the use of reproducible factors and exhibits greater technological dynamism than primary production. As such, its growth is central to long-run development in low-income countries. African countries are latecomers to industrialization, and barriers to manufacturing growth, including those that limit trade, have been slow to come down. What factors contribute most to increases in output and productivity growth in African manufacturing? Recent trade–industrial organization theory suggests that trade liberalization should raise average total factor productivity (TFP) among manufacturing firms (Melitz 2003). However, these predictions are conditional on maintained assumptions about the nature of industries, factor markets, and trade patterns that may not be appropriate in a developing-country setting. Manufacturing firms are heterogeneous, so the analysis demands disaggregated data. We use firm-level data from the World Bank’s Regional Program on Enterprise Development, covering Ghana, Kenya, Nigeria, and Tanzania for 1991–2003. Among other things, the data distinguish exports by destination (Africa and the rest of the world), which is important due to the spread of intra-African regional trade agreements (RTAs). Econometric results confirm well-known relationships, such as a positive association between export intensity and TFP, which implies that more productive firms are more likely to select in to exporting. However, we also find the destination of exports to be important. Many exporters have experienced declining TFP growth rates, which have occurred at different rates depending on the country and the export destination. The evidence for “learning by exporting” is thus mixed. These results add a new dimension to controversies over the development implications of trade liberalization and the promotion of intra-African RTAs.
