Does Tariff Liberalization Increase Wage Inequality? Some Empirical Evidence

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 databases of wage inequality that have become recently available and a large data set 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. However, the results for inter-occupational inequality though must be treated with caution
