Este trabalho objetivou analisar as mudanças ocorridas na despesa com água e esgoto, em resposta à alteração na renda das famílias nas regiões Norte, Nordeste, Centro-Oeste, Sudeste e Sul. Para isso, estimou-se a elasticidade-renda da despesa por meio de um modelo econométrico que consiste em ajustar uma poligonal com três segmentos, com vistas em mostrar como a despesa com água e esgoto varia em decorrência de uma alteração no recebimento familiar. Os dados foram extraídos da Pesquisa de Orçamento Familiar de 2002/2003, realizada pelo IBGE. Os valores encontrados para elasticidade-renda situaram-se entre 0 e 1, o que indica que a água pode ser considerada um bem normal nas regiões analisadas e no Brasil, onde o valor encontrado foi de 0,4263.

Autores: Figueiredo,   Adelson Martins; Oliveira,   Maria Aparecida Silva; Santos,   Maurinho Luiz dos.
No Acordo Agrícola da Rodada Uruguai e posteriores rodadas de negociações multilaterais foram propostas metas de redução de subsídios à agricultura. Mesmo assim, o que tem ocorrido é uma elevação dos volumes de recursos concedidos aos produtores agrícolas dos EUA. Salienta-se que os subsídios à produção agrícola nos EUA geram distorções no comércio mundial desses produtos, na medida em que reduzem suas importações e aumentam os excedentes exportáveis. Assim, o objetivo da presente pesquisa é avaliar os impactos dos subsídios à produção agrícola dos EUA – concedidos através dos Loan Deficiency Payments (LDP) – sobre o crescimento do agronegócio brasileiro. Para isso foi utilizado um Modelo Aplicado de Equilíbrio Geral (MAEG) para a economia dos EUA e do...

Autores: Cassuce,   Francisco Carlos da Cunha; Santos,   Maurinho Luiz dos.
This paper, supported on the theory of the Boarding of the Elasticities, had as objective to show the influence of the exchange rate depreciation in the value of the Brazilian exportations. For this purpose, Structural Vector Autoregressive Models (SVAR Models) where used to calculate the offer of foreign currency elasticities, determining if depreciations in the currency would increase or reduce the exported value of soybean. The results showed that cambial depreciations really raise the value of the Brazilian exportations. The impulse response functions show that the exportation price is the variable that exerted greater influence in the exported value, indicating, perhaps, that politics that degenerate the Brazilian soybean exportations can contribute...

Autores: Farias,   Christiano Alves; Vieira,   Wilson da Cruz; Santos,   Maurinho Luiz dos.
The objective of this paper was to compare and to analyze three portfolio selection models: Mean-Variance, Minimax and Minimax Weighted. These models were evaluated using historical data (September 1999 to August 2000, January 2001 to December 2001 and February 2002 to January 2003) obtained from the Brazilian Stock Market (Bovespa). They were selected optimal portfolios to each month based on the returns of the last twelve months. The results show that the returns obtained through the Mean-Variance model were superiors in certain circumstances and inferiors in others when compared to the Ibovespa index. The Minimax model obtained the best accumulated returns when compared with the others models and the Ibovespa index.

Provedor de dados: 31
Autores: Farias,   Christiano Alves; Vieira,   Wilson da Cruz; Santos,   Maurinho Luiz dos.
This paper presents a comparison of three portfolio selection models, Mean-Variance (MV), Mean Absolute Deviation (MAD), and Minimax, as applied to the Brazilian Stock Market (BOVESPA). For this comparison, we used BOVESPA data from three different 12 month time periods: 1999 to 2000, 2001, and 2002 to 2003. Each model generated three optimal portfolios for each period, with performance determined by monthly returns over the period. In general, the accumulated returns from the Minimax modeled portfolios were superior to the BOVESPA’s principal index, the IBOVESPA. The MV model was the least efficient for portfolio selection.
