This study analyzes the impacts of further tariff reductions resulting from the proliferation of regional trade agreements on wage inequality between skilled and unskilled workers in Chile in the 2000s. Thus, we use data on effective tariff rates instead of uniform most-favored-nation rates to measure trade liberalization. We match panel data on industry characteristics, including effective tariff rates, to pooled individual cross-section data from national household surveys at the industry level. We find that the reductions in effective tariffs on final goods increase industry wage premiums, thus suggesting that liberalization-induced productivity improvements lead to higher wages. However, considering the differential impacts on different skill groups, we find that the reductions significantly increase industry wage premiums only for skilled workers, thereby increasing wage inequality. Moreover, the impact is larger in skilled workers employed in large-sized firms. The results are robust to the inclusion of other industry characteristics, including input tariffs, the share of foreign-owned capital, and payments to foreign technology. The results are also robust to the inclusion of industry productivity, which is likely to affect the effective tariffs and industry wage premiums simultaneously, as well as control for the potential endogeneity of trade policy.

PurposeThis study aims to analyse the contribution of the expansion and diversification of higher education to Chile's increase in wage inequality from 1992 to 2000 and its subsequent decrease from 2000 to 2013.Design/methodology/approachThe wage equation for each year is estimated using data from the national household survey, Encuesta de Caracterización Socioeconómica Nacional (CASEN). Using the method proposed by Firpo et al. (2009), the evolution of wage changes is decomposed into composition and wage structure effects of each explanatory variable at different points of the wage distribution.FindingsThe results show that the positive composition effect of higher education, derived from the increasing share of both workers with university degrees and those with vocational degrees, is substantially larger at the upper quantiles and exceeds the negative wage structure effect, thereby contributing to increasing wage inequality from 1992 to 2000. By contrast, the negative wage structure effect of higher education, primarily derived from the decreasing return to university degrees, is substantially larger at the upper quantiles and exceeds the positive composition effect, thereby contributing to decreasing wage inequality from 2000 to 2013.Originality/valueThis study contributes to the literature by showing that the expansion of higher education increased inequality in the 1990s and decreased it in the 2000s while the increasing supply of workers with vocational degrees decreased wage premiums for university degrees in the latter period.

Information spillovers from multinational enterprises to local firms in developing countries are examined in the literature on global value chains and foreign direct investment. However, global value chain studies and foreign direct investment studies are carried out independently and separately. While global value chain studies describe an important mechanism that underlies the productivity improvements of local firms in developing countries, most foreign direct investment studies attempt to assess econometrically the impacts on the productivity of local firms. This survey article concludes that an integrated approach incorporating the insightful perspective of global value chain studies into the empirical approach of foreign direct investment studies will likely reveal the channel through which information spillovers lead to the productivity improvements of local firms in developing countries.

This study empirically analyzes whether trade liberalization increases wage inequality between skilled and unskilled workers in Chile during 1974-2007. The findings show that tariff reductions contributed to increases in wage inequality by causing price reductions of unskilled labor-intensive goods protected with the highest tariffs prior to trade liberalization. In contrast, we found no evidence that new technologies embodied in capital and intermediate goods caused skill-biased technological change. In addition, this study shows that an increase in the relative supply of college equivalents did not contribute to wage equalization, while an increase in the minimum wages contributed to wage equalization during the period of the democratic governments.
