The objective of the paper is to answer an often-asked question : if tariff rates are reduced, what will happen to wage inequality ? We consider two types of wage inequality : between occupations (skills premium), and between industries. We use two large data bases of wage inequality that have become recently available and a large dataset of average tariff rates all covering the period between 1980 and 2000. We find that tariff reduction is associated with higher inter-occupational and inter-industry inequality in poorer countries (those below the world median income) and the reverse in richer countries. The results for inter-occupational inequality though must be treated with caution.

"The authors provide new evidence on the impacts of trade reforms on wages and wage inequality in developing countries. While most of the current literature on the topic achieves identification by comparing outcomes before and after one episode of trade liberalization across industries, they propose a stronger identifying strategy. The authors explore the recent historical record of policy changes adopted by Argentina: from significant protection in the early 1970s, to the first episode of liberalization during the late 1970s, back to a slowdown of reforms during the 1980s, to the second episode of liberalization in the 1990s. These swings in trade policy comprise broken trends in trade reforms that they can compare with observed trends in wages and wage inequality. After setting up unusual historical data sets of trends in tariffs, trends in wages, and trends in wage inequality, the evidence supports two well-known hypotheses: trade liberalization, other things being equal, (1) has reduced wages, and (2) has increased wage inequality.

We evaluate empirically the impact of the dramatic 1991 trade liberalization in India on the industry wage structure. The empirical strategy uses variation in industry wage premiums and trade policy across industries and over time. In contrast to earlier studies on developing countries, we find a strong, negative, and robust relationship between changes in trade policy and changes in industry wage premiums over time. The results are consistent with liberalization-induced productivity increases at the firm level, which get passed on to industry wages. Since tariff reductions were proportionately larger in sectors that employ a larger share of unskilled workers, the increase in wage premiums in these sectors implies that unskilled workers experienced an increase in their relative incomes. Thus, our findings suggest that trade liberalization has led to decreased wage inequality in India.

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.
