O emprego na teoria econômica

O objetivo principal desta pesquisa é a teoria do emprego segundo os modelos macroeconômicos mais conhecidos. No início, abordamos a controvérsia sobre o conceito de desemprego no contexto dos mercados em equilíbrio, enfoque que consideramos inadequado para explicar as atuais taxas de desemprego, inclusive nos países desenvolvidos. De nossa parte, consideremos o desemprego, mais um problema social, cujas raízes se encontram no conflito de classes e no tipo de organização da sociedade, do que uma simples disfunção do sistema econômico. A teoria econômica sempre teve grande dificuldade em lidar com a variável trabalho e a economia do trabalho não possui uma estrutura básica. Este ensaio explora a vertente da economia do trabalho contida nos modelos macroeconômicos sem a preocupação de obter conclusões definitivas.

Labor supply, risk aversion and economic refrom in China

Economic reform in China has created a small, but fast-growing private sector that has spurred rapid productivity growth. Growth of the private sector is predicated upon continued labor movements away from state-run industries and into private firms. This paper presents a theory of labor market sectoral choice demonstrating that three factors determine private sector labor supply-the difference in wages between the state and private sectors, private sector wage risk and risk aversion. Estimation of the model using survey data provides strong support for the theory. We find that the riskiness of private sector earnings has a greater effect in discouraging workers from taking jobs in private firms than the wage premi um has in attracting workers.

Brazil’s 35 years-old quasi-stagnation: facts and theory

Brazil is growing around 1% per capita a year from 1981; this means for a country that is supposed to catch up, quasi-stagnation. Four historical new facts explain why growth was so low after the Real Plan: the reduction of public savings, and three facts that reduce private investments: the end of the unlimited supply of labor, a very high interest rate, and the 1990 dismantling of the mechanism that neutralized the Dutch disease, which represented a major competitive disadvantage for the manufacturing industry. New-developmental theory offers an explanation and two solutions for the problem, but does not underestimate the political economy problems involved
