Human capital and earnings inequality in Brazil, 1988-98 : quantile regression evidence

The authors undertake an empirical examination of rates of return to human capital for men in Brazil, through the period of macroeconomic stabilization and trade liberalization, using data from the 1988, 1992, and 1998 Brazilian household surveys (Pesquisa Nacional por Amostra de Domic?os, PNAD). The authors estimate simultaneous quantile equations to gain an insight on the impact of human capital on wages across the hourly earnings distribution. They conclude that there is evidence of growing inequality in rates of return to education in Brazil. But the authors find evidence that education is no longer used as a screening device in the labor market, but rather rewarded for its innate association with higher productivity. Although increases in rates of return to education have been more pronounced at the top of the earnings distribution, this has not led to increased inequality. This is because the levels of education and other labor market-rewarded endowments have increased and offset the rate of return effect.Public Health Promotion,Decentralization,Health Monitoring&Evaluation,Curriculum&Instruction,Teaching and Learning,Economic Theory&Research,Fiscal&Monetary Policy,Curriculum&Instruction,Teaching and Learning,Health Monitoring&Evaluation

Gender wage differentials in Brazil : trends over a turbulent era

Since the late 1980s, macroeconomic and trade reform in Brazil appears to have been accompanied by a substantial improvement in the position of women compared with men in the labor market, despite only modest changes to labor market institutions. The authors examine movements in the gender wage gap from 1988 to 1998. Their findings indicate that, over this period, the gender wage gap fell mainly because of reduced discrimination against women. But the authors find evidence to suggest that, more recently, since the elimination of high inflation, human capital investments and other earnings-related enhancements have begun to improve women's condition.Public Health Promotion,Anthropology,Health Monitoring&Evaluation,Gender and Development,Population&Development,Anthropology,Agricultural Knowledge&Information Systems,Environmental Economics&Policies,Health Monitoring&Evaluation,Population&Development
