| Being constituted as the largest risk factor and effective degradation to the Savannah, the man’s intervention in the nature and, especially, the agricultural exploration require analysis and better monitoring. This work aims to analyze the relationship between the agricultural exploration and the environmental degradation in the area of the Savannahs, in 1995-1996. In particular, it is intended, to use multivariate statistical analysis, to verify the factors associated with the intensity of farming predominant in the determination of the degradation pattern, and to obtain indexes of exploration intensity to make possible to categorize and to group the microrregions in terms of degradation potential. The results showed that the intensity of the... |

| The objective of this work is to analyze coffee production and processing in the economic structure of Minas Gerais, to determine its importance and its linkages to the structure of the State economy, by using input-output matrix. Therefore, it is determined linkages indexes of Rasmussen-Hirschman, boarding fields, pure linkage index (GHS) and regional multipliers of product, income and employment. These applications are complementary to the identification of key sectors of the economy. The 1995 input-output matrix was used. Linkages indexes of Rasmussen-Hirschman and the analysis of the influence field pointed out that coffee production presents multiplying indicators above those of the economy, presenting higher backward and forward linkages. The coffee... |

| This article presents a financial analysis of agricultural credit cooperatives in Minas Gerais, between 1998 and 2001. The financial indicators used in this study were separated in the following groups: struture, solvency, costs, financial returns and growth, whose definitions were extracted from the Austin Asis Consulting Company manual. The t-test, with a 5% level of significance, was used as a analytical framework for the financial performance from one year to the next one. As a general result, the indicators showed that the asset and liability accounts were in equilibria, allowing to conclude that the agricultural credit cooperatives of Minas Gerais are in a stable financial situation. |

| O estudo buscou avaliar a contribuição do setor transporte para a economia brasileira. Especificamente, pretendeu-se determinar os setores capazes de propagar efeitos sistêmicos acima da média da economia como também mensurar os impactos econômicos na produção, emprego e renda, resultantes de alterações na demanda final. Para tal, utilizou-se o modelo de insumo-produto, já que este instrumental possibilita verificar as ligações entre os setores produtivos por meio dos índices de ligações de Rasmussen-Hirschman, campos de influência e índices puros de ligações, bem como determinar os efeitos de variações na demanda final sobre a produção, a renda e o emprego através das análises dos multiplicadores. Os resultados revelaram que o setor transporte não foi... |

| Analisou-se a elasticidade de transmissão de preços e a formação espacial entre as principais regiões produtoras de leite do Brasil, no período de 1997 a 2005, pela análise de co-integração, e pelo Modelo Vetorial de Correção de Erro (VEC). Os resultados evidenciaram que a variação de 1% nos preços recebidos pelos produtores de leite de Minas Gerais leva a uma variação de 0,38%, 0,72%, 0,93% e 0,26% nos preços em São Paulo, Rio Grande do Sul, Paraná e Goiás, respectivamente. Pela estimação do VEC os coeficientes do Paraná e São Paulo, em módulo, foram comparativamente maiores aos demais. São Paulo foi menos interdependente, indicando comportamento mais isolado no padrão de liderança preço. Verificou-se que, com o passar dos meses os preços de Minas... |

| Given the relevance of the credit unions at national and world level, the objective of this work was to describe the profile of the financial cooperatives from the Brazilian state of Minas Gerais. This study is based on data collected in the period of May to June of 2004, and the sample of 18.85% of the population was selected to supply data. The results indicate that the cooperatives were, on average, 16 years old; 92% of the associates that requested loans were assisted; the delinquent loans level were of 22.34%; and older cooperatives established smaller interest rates than the new ones. The managers had appropriate perception of the true meaning of a cooperative and they agreed with the cooperative principle of voluntary and open membership. In... |

| The main objective of this study was to analyze the pattern of nutrient intake in major metropolitan region of Brazil, seeking to identify the nutrient intake adequacy in the Brazilian families, and their evolution over time. The Almost Ideal System (AIDS) model was employed to estimate the demand for nutrients. The data used are from the Household Budget Survey of 1995 and 2003. The results indicated that the nutrient demand of the population has poor sensitivity to changes in prices. In addition, families tend to demand relatively more fat, cholesterol and carbohydrates than vitamins and minerals. It was found that there was worsening in the pattern of intake for most nutrients from 1995 to 2003, in relation to daily nutrient recommendations. Thus,... |

| The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports |
