Financial risk monitoring and transaction costs in coffee & soybean trading companies and processors
2003
Edson Costa Bignotto | Adriano Azevedo Filho
This study characterizes the use of risk monitoring mechanisms by coffee and soybean trading and processing companies. It also investigates the role these mechanisms play in the mitigation of certain transaction costs associated to bounded rationality, information asymmetry, and business opportunism in negotiations involving derivatives. The results presented are based on literature and original research, which consisted of interviews with 19 coffee and soybean trading and processing company agents that deal with the management and execution of derivatives trades. The interviews suggest that the interest in formal risk monitoring mechanisms depends strongly on the organizational structure of the business. In family businesses, in which the owner participates actively in negotiations, the interest is limited. In non-family businesses, where there is a clear separation between supervisory upper-management and agents involved with trading, the interest in risk monitoring systems is more evident. This result seems to indicate that the mitigation of transaction costs associated with information asymmetry and opportunism might be stronger motivations for interest in risk monitoring mechanisms than the costs resulting from bounded rationality.
اظهر المزيد [+] اقل [-]Relative intensity of bilateral trade flows, regional integration, and trade performance: the case of Brazil, 1984-1998
2003
Silva Valquiria da | Anefalos Lilian C. | R. Filho José Carlos G. dos
The objective of this research is to identify the component of trade that results specifically from bilateral relations and evaluate how the creation of trading blocs affects trade relations between countries. The trirapport coefficient of the relative intensity of bilateral agricultural sector trade flows between Brazil and other countries from 1984 and 1998 is used in the evaluation. In general, the results show that relative trade intensity between Brazil and its non-MERCOSUL trade partners fell after their entry into regional trade agreements (extra-bloc effect). The intra-bloc effect (trade expansion) is reflected by changes in trade intensity between Brazil and the other MERCOSUL members and changes in trade intensity between NAFTA members Mexico, Canada, and the United States.

2003
Mattos Fabio L. | Ferreira Filho Joaquim Bento de Souza
According to Portfolio Theory, by combining assets that show a correlation inferior to one (1) among their individual returns, it becomes possible to create portfolios that reduce risk without damaging expected return. Crop and livestock futures contracts and company stocks show such a characteristic, which signals potential benefits when forming portfolios combining these two types of assets. This investment strategy is not often utilized in Brazil. The purpose of our research was to assess whether such an asset combination is actually advantageous to those creating investment portfolios in the Brazilian market. Our evaluation used instruments of analysis developed by Markowitz in Portfolio Theory and data about the return from crop and livestock futures contracts and stocks. The data was gathered from the Brazilian Futures and Commodities Exchange (BM&F) and Brazil?s National Association of Open Market Institutions (ANDIMA) between July 1994 and December 1998. The results of this work showed that the combination of these two types of assets in investment portfolios can be an interesting portfolio management alternative.

2003
Henrique D. Neder
The growth of non-agricultural activity since the 1980s has reconfigured the economic and social dynamic in Brazil’s rural areas. Our paper intends to describe the impact of this growth on income distribution in rural Brazil. We made use of a method of decomposition of two indicators of income distribution applied to1992 and 1999 Brazilian National Household Sample Survey (PNAD) data: the variation coefficient and the Gini index. It was observed that non-agricultural activities have increased the concentration of rural income and that this phenomenon is more prominent in Region I (states of Brazil’s Northeast and the state of Tocantins) and Region IV (states of São Paulo and Mato Grosso do Sul and the Distrito Federal). It was found that the income concentrating effect of each non-agricultural activity branch (commerce, transformation industry, administration, service) differed by region. In Region I, income from the "Social/Public Administration and Other Activities branch " (a PNAD designation) presents a coefficient of relative concentration greater than a unit, which indicates that income from this activities branch acts to increase the concentration of non-agricultural income in this region. In Region IV, income from industrial activities and from Social/ Public Administration and Other Activities both present coefficients of relative concentration greater than a unit; therefore, both branches act to increase the concentration of income from non-agricultural activities in this region.

2003
Benedito Silva Neto | Telmo Rudi Frantz
O papel fundamental desempenhado pelas atividades econômicas não-agrícolas no desenvolvimento rural brasileiro tem sido evidenciado por vários estudos. O presente trabalho tem como objetivo analisar a hipótese de que uma parte importante das atividades não-agrícolas presentes no meio rural da maioria dos municípios do Rio Grande do Sul foi originada pela demanda de bens e serviços da própria população destes municípios. Uma análise da formação dos municípios ao longo da história do Rio Grande do Sul indicou que a densidade demográfica, assim como o nível e a distribuição da renda dos agricultores são variáveis importantes para explicar o seu desenvolvimento. A partir destas constatações elaborou-se um modelo matemático analítico que permitisse explicitar as relações destas variáveis (população rural, nível e distribuição da renda) com a demanda de bens e serviços locais. Os resultados obtidos no trabalho, especialmente as implicações formais dos modelos formulados, indicam que a manutenção da população no campo, a ampliação da renda dos agricultores e a promoção de uma melhor distribuição desta renda, podem ser elementos importantes de uma política de estímulo a atividades nãoagrícolas no meio rural, o que, no entanto, não exclui a necessidade de medidas específicas de apoio à criação de atividades não-agrícolas como, por exemplo, crédito, assistência técnica e capacitação de recursos humanos.
اظهر المزيد [+] اقل [-]Risk analysis of investments in-farm milk cooling tanks
2003
Danielle D. Sant´Anna | Carlos Arthur B. da Silva | Sebastião T. Gomes
A risk analysis for the installation of milk cooling tanks (250, 500 and 1,000 L) on Brazilian rural properties was conducted in this study. The results showed that all investments had a return higher than the annual 12% minimum rate of attractiveness. There was a direct relationship between tank size and investment profitability and an inverse relation between size and risk. The probability of achieving returns lower than the opportunity cost was highest for the smallest tank (42%). In order to make the investment in small cooling tanks more attractive, the dairy industry incentives offered to farmers for supplying cooled milk could be increased. However, this approach might make investments in bulk milk collection by dairy companies infeasible. Thus, a recommendable strategy for a successful modernization of the Brazilian dairy sector’s inbound logistics would be to promote an increase in the volume of the milk produced per farm.
