O aluno de aprendizagem lenta no âmbito da marginalização cultural

O presenté trabalho estuda o aluno de aprendiza~ gem lenta no âmbito da marginalização cultural, utilizando literatura específica e amostra de educandos da rede escolar oficial do Município do Rio de Janeiro. A literatura específica procurou esclarecer pontos importantes relativos ao desenvolvimento intelectua~ i marginalização cultural, aos distúrbios de aprendizagem, i relação da criança com a família, ã relação do aluno com o professor bem como estudos relativos ao aluno de aprendiz~ gem lenta. Com base na literatura específica foram elaboradas entrevistas com as mães e os professores dos alunos, assim como escolhidos testes objetivos para aferição do ní vel mental e nível de prontidão para a aprendizagem de lei tura, escrita e números .dos alunos. Os resultados da analise confirmaram as hipóteses levantadas de que a carência de estimulação ambiental prejudica o desenvolvimento intelectual e acarreta maior difi culdade de aprendizagem, que a relação professor-aluno tan to pode reforçar como minimizar a problematica apresentada e que a criança oriunda de classe de baixa renda econ~mica tem maiores possibilidades de enquadrar-se na marginalização cultural. Ao final do trabalho, algumas sugestoes foram tra çadas quanto a procedimentos que possam ser adotados tanto com a população estudada como com populações semelhantes.

Income composition, endogenous fertility and schooling investments in children

This paper studies how the eomposition of ineome between mothers and fathers affeets fertility and sehooling investments in ehildren, using data from the 1976 and 1996 PNAD, a Brazilian household survey. Ineome composition affeets the time eost of fertility because mothers and fathers alloeate different amounts of time to child-rearing. These effects are in turn transmitted to investments in ehildren through a tradeoffbetween quantity and quality of ehildren. The main contribution of this paper is twofold. First, it derives new implications about the relationship between household ineome composition and schooling investments in ehildren. Seeond, this paper devises and implements an empirieal approaeh to assess these implieations, using two eross-seetions of fertility and schooling data from Brazil. The main empirical findings of the paper ean be summarized as follows. First, the empirical analysis shows that a larger negative effect of the mother's labor in come on fertility in 1996 is associated with a larger positive effect on the adult child's schooling, refleeting the interaction between quantity and quality of children. Second, the larger negative effect of the mother's labor income on fertility in 1996 is associated with a reduction in the effect of other determinants of number of children. This suggests that an increase in the relative importanee of time costs of fertility may be an important determinant of variations in fertility over time in Brazil and other developing countries .

Wealth composition, endogenous fertility and the dynamics of income inequality

This paper analyzes how differences in the composition of wealth between human and physical capital among families affect fertility choices. These in tum influence the dynamics of wealth and income inequality across generations through a tradeoffbetween quantity and quality of children. Wealth composition affects fertility because physical capital has only a wealth effect on number of children, whereas human capital increases the time cost of child-rearing in addition to the wealth effect. I construct a model combining endogenous fertility with borrowing constraints in human capital investments, in which weaIth composition is determined endogenously. The model is calibrated to the PNAD, a Brazilian household survey, and the main findings of the paper can be summarized as follows. First, the model implies that the crosssection relationship between fertility and wealth typically displays a U-shaped pattem, reflecting differences in wealth composition between poor and rich families. Also, the quantity-quality tradeoff implies a concave cross-section relationship between investments per child and wealth. Second, as the economy develops and families overcome their bOlTowing constraints, the negative effect of weaIth on fertility becomes smaller, and persistence of inequality declines accordingly. The empirical evidence presented in this paper is consistent with both implications .
