| This study analyzes the transmission elasticity and the price causality of beef, between BM&F and important places in Brazil, seeking data referring to the intensity of price transmission and detecting the existent relations between beef price in these places and in BM&F. Studies in several regions were realized, using daily price data in a period comprehended between 2000 and 2004. The studied cities were Araçatuba (SP), Barretos (SP), Bauru (SP), Presidente Prudente (SP), Noroeste do Paraná (PR), Três Lagoas (MS), Campo Grande (MS), Triângulo Mineiro (MG), Dourados (GO), Goiânia (GO) and Cuiabá (MT). The results of the Dickey-Fuller Augmented (DFA) unit root test show that all price series are integrated of first order, I(1). The results of the... |

| Dentre os produtos agrícolas exportados pelo Brasil, o café mantém seu destaque. Esta cultura é representativa para o saldo positivo da balança comercial brasileira e também na geração de empregos, principalmente os diretos, os quais contribuem significativamente com a fixação do trabalhador no meio rural. O objetivo desse estudo foi o de estimar os custos de produção de café nos estados de Minas Gerais, Paraná, Espírito Santo e São Paulo e mensurar o impacto da produtividade no resultado financeiro de propriedades cafeeiras. O custo de produção é uma informação financeira fundamental para a avaliação do desempenho do negócio café. Os custos são medidas monetárias ligadas diretamente ao processo produtivo, ou seja, a aplicação de recursos na produção de... |

| A spreadsheet featuring production costs for coffee in different productivity ranges is presented in this study. The survey is based on the theory of costs and the study location was the southern region of the state of Minas Gerais, where data on 48 coffee production units were gathered during the 1998/99 harvest. Taking the economical indexes resulting from research into consideration, one may infer that expenses on variable resources represent the greater portion of the final cost of coffee. The items which affected production costs the most were crop formation, in the case of unvariable costs, and the expenses on labor, especially the seasonal kind. It was also concluded that coffee culture belongs to the scale-economy kind and , as a whole, the 1998/99... |

| Human forecasting capacity is still very limited. In spite of the extreme efforts of specialists in several different areas for years developing scientific knowledge, forecasting various events, such as climatic conditions at a given time, the evolution of a commodity price in the future, remain subject liable to a considerably high degree of error. Therefore, this paper aims to compare forecast price models for the Live Cattle market at Brazilian Mercantile and Future Exchange (BM&F) using models based in Neural Networks and statistical tools of heteroscedastic times series. The data used correspond to the closing of the live cattle prices, in the period ranging from August 1997 to May 2005, totalizing 1946 observations. The results show the supremacy... |
