This report quantifies labor mobility costs in developing countries and simulates the implied adjustment paths of employment and wages following a change in trade policy. High mobility costs are shown to reduce the potential gains to trade reform.

Over the past two decades, the percentage of the world’s population living on less than a dollar a day has been cut in half. How much of that improvement is because of—or in spite of—globalization? While anti-globalization activists mount loud critiques and the media report breathlessly on globalization’s perils and promises, economists have largely remained silent, in part because of an entrenched institutional divide between those who study poverty and those who study trade and finance. Globalization and Poverty bridges that gap, bringing together experts on both international trade and poverty to provide a detailed view of the effects of globalization on the poor in developing nations, answering such questions as: Do lower import tariffs improve the lives of the poor? Has increased financial integration led to more or less poverty? How have the poor fared during various currency crises? Does food aid hurt or help the poor? Poverty, the contributors show here, has been used as a popular and convenient catchphrase by parties on both sides of the globalization debate to further their respective arguments. Globalization and Poverty provides the more nuanced understanding necessary to move that debate beyond the slogans.

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.

October 1995 Cuts in Mexico's tariff levels were associated with a slight decline in employment in Mexico and with increases in average wages (perhaps reflecting improved productivity in the reformed industries and a shift toward the use of more skilled workers). The wages and employment of skilled production workers were significantly more responsive to changes in protection levels than those of nonproduction workers. In 1985, after decades of an import-substitution industrial strategy, Mexico initiated a radical liberalization of its external sector. Between 1985 and 1988, import licensing requirements were scaled back to a quarter of earlier levels, reference prices were removed, and tariff rates on most products were substantially reduced. By 1989, Mexico was one of the most open economies in the developing world. Adjusting to trade liberalization required the reallocation of resources between sectors and entailed substantial dislocation of workers. Revenga analyzes how Mexico's trade liberalization (1985 - 87) affected employment and wages in industry, focusing on how it affected average employment and earnings rather than on the link between trade and relative wages. She examines the tradeoff between wage and employment adjustment, identifies which labor groups benefited more from liberalization, and tries to associate changes in employment and wages directly with measures of change in trade protection, rather than link them to changes in imports and exports (which is more common). She finds that reductions in quota coverage and tariff levels are associated with moderate reductions in firm-level employment. A 10-point reduction in tariff levels (between 1985 and 1990) is associated with a 2- to 3-percent decline in employment in Mexico. Changes in quota coverage appear to have no discernible effect on wages, but reductions in tariff levels are associated with increases in average wages. This seems to reflect improved productivity in the reformed industries, which may be related to a shift toward the use of more skilled workers. There seems to have been a slight shift in the skill mix in favor of nonproduction workers. This was paralleled by a sharper increase in the wage differential between skilled and unskilled workers. The wages and employment of skilled production workers were significantly more responsive to changes in protection levels than those of nonproduction workers -- perhaps partly because production workers were more heavily concentrated in the industries in which protection levels were greatly reduced. This paper -- a product of the Country Operations Division 1, Latin America and the Caribbean, Country Department II -- was prepared for the World Bank labor markets workshop held in July 1994.
