The distribution of male wages in Brazil

This paper examines the evolution of wage inequality in Brazil in the 1980s and 1990s . It tries to investigate the role played by changing economic returns to education and to experience over this period together with the evolution of within-group inequality. It applies a quantile regression approach on grouped data to the Brazilian case. Results using repeated cross-sections of a Brazilian annual household survey indicate that : i) Male wage dispersion remained basically constant overall in the 1980's and 1990' s but has increased substantially within education and age groups. ii) Returns to experience increased significantly over this period, with the rise concentrated on the iliterate/primary school group iii) Returns to college education have risen over time, whereas return to intermediate and high-school education have fallen iv) The apparent rise in within-group inequality seems to be the result of a fall in real wages, since the difference in wage leveIs has dec1ined substantially over the period, especially within the high-educated sample. v) Returns to experience rise with education. vi) Returns to education rise over the life-cycle. vii) Wage inequality increases over the life-cycle. The next step i~ this research will try to conciliate all these stylised facts.

Entrepreneurial risk and labour's share in output

This paper presents a theoretical model which discusses the role played by the entrepreneurial risk on the distribution of the national income. In a two-period general equilibrium framework with competitive risk-averse entrepreneurs it is shown that the highest the risk borne by firms, the lower will be real wages, employment and the labour's share in output. The model helps explain the fall of the labour's share in the Brazilian output during the 1980s.

Why foreign savings fail to cause growth

Este artigo é uma formalização da crítica à estratégia do crescimento com poupança externa que um de seus autores vem sendo fazendo nos últimos anos. Apesar dos países de renda média serem pobres de capital, os déficits em conta corrente (poupança externa), financiado seja por empréstimos ou por investimentos externos diretos, não irá aumentar a taxa de acumulação de capital ou terá pouco impacto sobre ela, uma vez que os déficits de conta corrente estarão associados taxas de câmbio apreciadas, ordenados e salários aumentados artificialmente e altos níveis de consumo. Consequentemente, a taxa de substituição da poupança externa pela interna será relativamente alta, e o país será obrigado não a investir e crescer, mas a consumir. Apenas quando há grandes oportunidades de investimento, estimuladas por uma ampla diferença entre a taxa de lucro esperada e a taxa de juros de longo prazo, a propensão marginal ao consumo diminuirá suficientemente, a ponto de o lucro adicional originário do fluxo de capital estrangeiro ser usado para investimento, ao invés de para consumo. Neste caso especial, a taxa de substituição de poupança externa pela interna tenderá a ser menor e a poupança interna contribuirá positivamente para o crescimento

Exchange rate: fix, float, or manage it?

The Exchange Rate is the Most Strategic of the Four Macroeconomic Prices. it Determines not Only Exports and Imports, But Also Real Wages, Consumption and the Savings Rate. Conventional Theory Holds That it is Impossible to Manage It, and That the Only Alternatives are to Fix or to Float It. the Experience of the East Asian Countries, That Use it Strategically, Demonstrates That This Claim is False.

Crítica do crescimento com poupança externa

O presente artigo é uma formalização da crítica à estratégia do crescimento com poupança externa. Apesar dos países de renda média serem pobres em capital, os déficits em conta corrente (poupança externa), financiados por empréstimos ou investimentos diretos externos, não necessariamente farão aumentar a taxa de acumulação de capital ou, mesmo, terão pouco impacto sobre ela, de forma que os déficits em conta serão associados a taxas de câmbio apreciadas, altos salários e ordenados reais e altos níveis de consumo. Conseqüentemente, o país se endividará para consumir, e não para investir e crescer. Apenas quando há grandes oportunidades de investimento, estimulados por uma diferença considerável entre a taxa de lucro esperada e a taxa de juros a longo prazo, o lucro adicional produzido pelo fluxo de capital estrangeiro será usado para investimento, e este trade-off entre a redução da poupança externa e interna não ocorrerá

A substituição de trabalhadores como instrumento para redução de gastos com salários: evidências para a indústria paulista

Labor churning is an important component of labor turnover in Brazil, which includes job reallocation between firms. The labor churning evolution in the nineties, at least for the industry sector in Sao Paulo, folows a very similar path for di erent groups of firms (divided by size or by subsectors), suggesting that changes in the macroeconomic environment a ect labor churning in a very similar way for different firms. This paper proposes a model to explain the path of formal labor churning in Brazil. The model admits that employers, when facing exogenous shocks that rise real wage, may substitute employees to reduce wage costs, particularly in low inflation periods, when real wages are more rigid. An econometric analysis is conducted using disaggregated data by firms for the industry sector in the Metropolitan Region of Sao Paulo. The results confirm the models main hipotesis. The results also suggest that, after the monetary estabilization, controlling for inflation and with valid instruments, labor churning is relatively higher

Os efeitos da redução da jornada de trabalho de 48 para 44 horas semanais sobre o mercado de trabalho no Brasil

The reduction of standard weekly working hours from the curreilt leveI of 44 hours to 40 hours has recently been proposed by the main central unions as a way to create jobs and reduce unemployment in Brazil. The idea, known as work-sharing, is that the reduction in average hours per worker allows the same tasks to be performed bymore employees. However, the notion ofwork-sharing has been challenged by the theoretical and the empirical literature. Theory says that, in general, a reduction in the duration ofthe workweek tends to decrease employment. Work-sharing is even less likely in the case of no wage restraint, when monthly wages are not proportionally reduced. Recent cautious econometric evidence also conflict with the notion of work -sharing (Hunt, 1999, and Crépon and Kramarz, 2000). The objective ofthis paper is to study the effects ofthe workweek length reduction from 48 to 44 hours, prescribed by the 1988 Constitutional change, on the Brazilian labor market. We find that: i) the reduction of standard working hours was followed by a significant decrease in actual working hours: 60,7% ofthe employees that worked between 45 and 48 weekly hours in 1988 (the affected group) and that remained employed in 1989 switched to a 40-44 hours workweek; ii) belonging to the affected group in 1988 had no statistical effect on the probability ofbecoming unemployed, exiting the labor market, or switching to an informal job in 1989; iii) the reduction in working hours implied a 8,8% increase in hourly real wages with respect to those that remained employed at 40-44 hours a week. In sum, the reduction of standard working hours in 1988 reduced actual working hours, did not affect the probability ofa typical worker to lose hisjob in 1989, and implied a relative increase in hourly real wages.
