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...

Autores: Rodrigues,   Cristiana Tristao; Coelho,   Alexandre Braganca; Braga,   Marcelo Jose; Gomes,   Adriano Provezano.
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,...

Fear or Greed? Duty or Solidarity? Motivations and Stages of Moral Reasoning: Experimental Evidences from Public-Goods Provision Dilemmas
Provedor de dados: 31
Autores: Meyer,   Leandro Fredrico Ferraz; Braga,   Marcelo Jose.
As economists increasingly recognize the limits of the canonical self-interest assumption, the lack of a theory of human valuation that clearly specifies what determines an individual’s utility judgments renders the prediction of behavior in social dilemmas virtually impossible.  In this study, we examined the explanatory power of a structuralist-constructivist theory of adult development and this theory’s analytical significance to the understanding of behavioral diversity in situations where individual and collective interests collide. Experimental results suggest that the theoretical constructs built into the selected theory provide a reliable basis for predicting participants’ behavior when presented with two different collective-action dilemmas under...

Autores: Bressan,   Valéria Gama Fully; Braga,   Marcelo Jose; Bressan,   Aureliano Angel.
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.

Autores: Cunha,   Denis Antonio da; Braga,   Marcelo Jose; Campos,   Antonio Carvalho; Fernandes,   Luciany Lima.
The robusta coffee market has experienced changes which are characterized by a growth in the demand and the confirmation of Vietnam as the world’s greater producer and exporter leaving behind traditional producers as Indonesia. These changes motivated the analysis of international price integration and the main markets of this commodity: Vietnam, Brazil, Indonesia and India. It was tested the hypothesis that Vietnam transmits prices shocks to the other markets. The framework used the analysis of co-integration and the Vector Error Correction (VEC) model. It was shown that, in the period from 1988 to 2005, the foreign price and the ones from Vietnam, Brazil and Indonesia were integrated and the India’s price was affected by factors that are not common to...

Autores: Coronel,   Daniel Arruda; Amorim,   Airton Lopes; Braga,   Marcelo Jose; Campos,   Antonio Carvalho.
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

Provedor de dados: 31
Autores: Pereira,   Vanessa da Fonseca; Campos,   Antonio Carvalho; Braga,   Marcelo Jose; Mendonca,   Talles Girardi de.
This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...
