Oferta de Força de Trabalho Familiar e Crise Econômica: Brasil me Tropolitano, 1983

This article develops a labor force participation model taking the family as unity of analysis. The model is applied to the metropolitan areas of the Northeast and Southeast for the year of 1983. The source of data is the National Household Survey (PNAD). It is assumed that all heads of family are in the labor force. They are classified by income and sex. It is tested whether increases in the labor force participation rate of secondary family members is associated with declines in the income of the head and the growth of family unemployment. Both hypothesis are verified. In the case of the income-effect it was found that declines in the head"s income leads to an increase in the labor force participation of secondary family members (wives or husbands, children and others). However this effect is strong only for those families whose head earns up to one minimum wage. For higher incomes the incomeeffect weakens and even, in a few cases, it is non-significant for some groups. For the unemployment-effect, group, increases in family unemployment leads to a growth in family labor force participation rates.
