Horas de trabalho: efeitos idade, período e coorte [Working hours: the effects of age, period and cohort].

Abstract

This article analyzes the evolution of working hours in Brazil from 1981 to 1999. The data are based on the PNAD (Household National Survey). The econometric model used has its grounds on the methodology age-period-cohort, which allows us not only to analyze the effects related to individual and job position aspects, but also to identify standards of working hours evolution through generations and life cycles. These effects - age, period and cohort - are relevant to the better understanding of recent working hours in Brazil. In general, the evolution of these effects is related to aspects of labor supply and demand and to institutional factors.working hours; Brazil
