Estabilidade política, poupança privada e crescimento: teoria e evidência

O objetivo desta pesquisa é mostrar empiricamente que há uma relação positiva entre a estabilidade política-institucional e a poupança. Em primeiro lugar, a pesquisa procura aprofundar, vis-à-vis a literatura contemporânea sobre o tema, a análise teórica microeconômica da determinação da poupança privada, levando em consideração argumentos derivados da Nova Economia Institucional. Em segundo lugar, a pesquisa envolve seis testes em cross-section, considerando economias em desenvolvimento e desenvolvidas, dentro de um modelo de determinação de poupança que incorpora um índice de satisfação do direito de propriedade (PROP) como uma das variáveis explicativas. A principal conclusão, empírica, reforça a recomendação normativa segundo a qual direitos de propriedade bem definidos e garantidos pelo Estado são fundamentais para assegurar a estabilidade institucional necessária para fomentar a formação de poupança na economia.

Determinantes de rentabilidade de empresas apoiadas pelo Programa BNDES de Desenvolvimento da Indústria de Software - BNDES PROSOFT Empresa

Este estudo objetiva analisar fatores que impactam a lucratividade de companhias beneficiadas com o Programa para Desenvolvimento da Indústria Nacional de Software e Serviços de TI – BNDES PROSOFT. A análise da lucratividade permeia diversos estudos no país e no exterior e é de suma importância para a realização de políticas públicas de qualidade. Para a avaliação, foram elencados diferentes aspectos microeconômicos, incluindo informações contábeis, de emprego, localização da empresa, segmento de atuação, entre outros, utilizando a metodologia de dados em painel. Dentre os resultados obtidos, pode-se destacar o impacto positivo do nível da escolaridade da equipe, lucratividade observada no exercício anterior, maior retorno das empresas menores frente às de maior porte. Houve penalidade no lucro daquelas companhias voltadas para fabricação de hardware, com equipes maiores. Constatou-se, também, um decréscimo no lucro de empresas no ano em que contrataram financiamentos com o BNDES, estas que foram posteriormente beneficiadas, no momento da implantação do projeto.

Brazilian international and inter-state trade flows: an exploratory analysis using the gravity model

Recent efforts toward a world with freer trade, like WTO/GATT or regional Preferential Trade Agreements(PTAs), were put in doubt after McCallum's(1995) finding of a large border effect between US and Canadian provinces. Since then, there has been a great amount of research on this topic employing the gravity equation. This dissertation has two goals. The first goal is to review comprehensively the recent literature about the gravity equation, including its usages, econometric specifications, and the efforts to provide it with microeconomic foundations. The second goal is the estimation of the Brazilian border effect (or 'home-bias trade puzzle') using inter-state and international trade flow data. It is used a pooled cross-section Tobit model. The lowest border effect estimated was 15, which implies that Brazilian states trade among themselves 15 times more than they trade with foreign countries. Further research using industry disaggregated data is needed to qualify the estimated border effect with respect to which part of that effect can be attributed to actual trade costs and which part is the outcome of the endogenous location problem of the firm.

Microeconomic instability and children's human capital accumulation: the effects of idiosyncratic shocks to father's income on child labor, school drop-outs and repetition rates in Brazil

This paper evaluates the long-run effects of economic instability. In particular, we study the impact of idiosyncratic shocks to father’s income on children’s human capital accumulation variables such as school drop-outs, repetition rates and domestic and non-domestic labor. Although, the problem of child labor in Brazil has declined greatly during the last decade, the number of children working is still substantial. The low levels of educational attainment in Brazil are also a main cause for concern. The large rotating panel data set used allows for the estimation of the impacts of changes in occupational and income status of fathers on changes in his child’s time allocation circumstances. The empirical analysis is restricted to families with fathers, mothers and at least one child between 10 and 15 years of age in the main Brazilian metropolitan areas during the 1982-1999 period. We perform logistic regressions controlling for child characteristics (gender, age, if he/she is behind in school for age), parents characteristics (grade attainment and income) and time and location variables. The main variables analyzed are dynamic proxies of impulses and responses, namely: shocks to household head’s income and unemployment status, on the one hand and child’s probability of dropping out of school, of repeating a grade and of start working, on the other. The findings suggest that father’s income has a significant positive correlation with child’s dropping out of school and of repeating a grade. The findings do not suggest a significant relationship between a father’s becoming unemployed and a child entering the non-domestic labor market. However, the results demonstrate a significant positive relationship between a father becoming unemployed and a child beginning to work in domestic labor. There was also a positive correlation between father becoming unemployed and a child dropping out and repeating a grade. Both gender and age were highly significant with boys and older children being more likely to work, drop-out and repeat grades.
