Abstract
Using micro data for the urban areas of Argentina, Brazil, Chile, Colombia, and Mexico, the authors document trends in men's returns to education during the 1980s and the 1990s and estimate the role of supply and demand factors in explaining the changes in skill premia. They propose a model of demand for skills with three production inputs, corresponding to workers with primary-, secondary-, and university-level education. Further, the authors demonstrate that an unprecedented rise in the supply of workers having completed secondary-level education depressed their wages relative to workers with primary-level education throughout Latin America. This supply shift was compounded by a generalized shift in the demand for workers with tertiary education.

Publication Off and Running? Technology, Trade and the Rising Demand for Skilled Workers in Latin America(World Bank, Washington, DC, 2003-04)The authors describe the evolution of relative wages in five Latin American countries-Argentina, Brazil, Chile, Colombia, and Mexico. They use repeated cross-sections of household surveys, and decompose the evolution of relative wages into factors associated with changes in relative supply and relative demand. The authors have three main conclusions: 1) Increases in the relative wages of the most skilled (university-educated) workers took place concurrently with increases in their relative abundance in all of the countries except Brazil. This is strong evidence of increases in the demand for skilled workers. 2) Increases in the wage bill of skilled workers occurred largely within sectors, and in the same sectors in different countries, which is consistent with skill-biased technological change. 3) Trade appears to be an important transmission mechanism. Increases in the demand for the most skilled workers took place at a time when countries in Latin America considerably increased the penetration of imports, including imports of capital goods. The authors show that changes in the volume and research and development intensity of imports are significantly related to changes in the demand for more skilled workers in Latin America. Their research complements earlier work on the effects of technology transmitted through trade on productivity and on the demand for skilled labor.Publication Closing the Gap in Education and Technology(Washington, DC: World Bank, 2003)This report focuses not only on the gaps facing Latin America in both education and technology, but especially on the interactions between the two. The central premise of the report is that skills and technology interact in important ways, and this relationship is a fundamental reason for the large observed differences in productivity and incomes across countries. This report argues that skills upgrading technological change, and their interaction are major factors behind total factor productivity growth. Skill-biased technological change is indeed being transferred today at faster speeds to LAC countries, as elsewhere. Technological change has been complementary with skill levels in Latin America in the last two decades. It is further estimated that firms have substantially increased the demand for educated workers in the region, particularly workers with tertiary education. This technological transformation appears to be intimately related to patterns of integration in the world economy. Firms in sectors with higher exposure to trade are subject to more competitive pressures. Adopting and adapting more advanced technologies and hiring and training more educated workers is one way to respond to this pressure to become more productive. The increased potential demand for education offers the possibility to accelerate productivity growth in the economy by closing the educational and technological gaps that Latin American countries exhibit with respect to their peers.Publication Educational Upgrading and Returns to Skills in Latin America : Evidence from a Supply-Demand Framework, 1990–2010(2011-12-01)It has been argued that a factor behind the decline in income inequality in Latin America in the 2000s was the educational upgrading of its labor force. Between 1990 and 2010, the proportion of the labor force in the region with at least secondary education increased from 40 to 60 percent. Concurrently, returns to secondary education completion fell throughout the past two decades, while the 2000s saw a reversal in the increase in the returns to tertiary education experienced in the 1990s. This paper studies the evolution of wage differentials and the trends in the supply of workers by educational level for 16 Latin American countries between 1990 and 2000. The analysis estimates the relative contribution of supply and demand factors behind recent trends in skill premia for tertiary and secondary educated workers. Supply-side factors seem to have limited explanatory power relative to demand-side factors, and are only relevant to explain part of the fall in wage premia for high-school graduates. Although there is significant heterogeneity in individual country experiences, on average the trend reversal in labor demand in the 2000s can be partially attributed to the recent boom in commodity prices that could favor the unskilled (non-tertiary educated) workforce, although employment patterns by sector suggest that other within-sector forces are also at play, such as technological diffusion or skill mismatches that may reduce the labor productivity of highly-educated workers.Publication India's Increasing Skill Premium : Role of Demand and Supply(2010)Using micro data for India from 1983 to 2005, this paper finds that the tertiary (college)-secondary (high school) wage premium has been increasing in India over the past decade and that this increase differs across age groups. The increase in wage premiums has been driven mostly by younger age groups while older age groups have not experienced any significant increase. Using a demand and supply model with imperfect substitution across age groups (developed in Card and Lemieux, 2001), this paper demonstrates that workers are not perfect substitutes across age groups. The paper finds that the increase in the wage premium has come mostly from demand shifts in favor of workers with a tertiary education. More importantly, the growth rate of demand for tertiary educated workers relative to secondary educated workers was fairly stable in the 1980s and the 1990s. However, the relative supply played an important role not only in determining the extent of increase in wage premium, but also its timing. The increase in relative supply of tertiary workers during 1983-1993 negated the demand shift; as a result, the wage premium did not increase much. But during 1993-1999, the growth rate of the relative supply of tertiary workers decelerated, while relative supply became virtually stagnant during 1999-2004. Both these periods saw an increase in the wage premium as the countervailing supply shift was weak.Publication Trade Liberalization and Labor Reform in Latin America and the Caribbean in the 1990s(World Bank, Washington, DC, 2002-05)This note synthesizes the findings of research on trade and labor in the region, including World Bank studies on: (i) trade and job quality, (ii) informality, and (iii) labor policies in the region. First, the evidence on the relationship between trade liberalization, macro-restructuring and labor market outcomes during the 1990s is reviewed. Second, labor market rigidities will be analyzed and the extent to which reform efforts facilitated formal employment creation. Finally, based on lessons learned from the 1990s, a new agenda for labor market reform is proposed which reflects more closely the new environment in which Latin American governments now operate.
