Última ANÁLISE COMPARATIVA ENTRE ESTRATÉGIAS DE HEDGE COM BASE EM MODELOS ESTÁTICOS E DINÂMICOS PARA CONTRATOS FUTUROS DE CAFÉ ARÁBICA AgEcon Muller, Carlos Andre da Silva; Moura, Altair Dias de; Lima, Joao Eustaquio de. Dentro do agronegócio brasileiro, o café arábica está entre os produtos com o mais elevado nível de risco e, ainda assim, é um produto importante para a economia brasileira. Os mercados futuros são reconhecidos como meio de gerenciamento desses riscos, mas observou-se o baixo uso desse mecanismo no caso brasileiro. Por outro lado, a literatura tem avançado quanto aos métodos para realização de estratégias de hedge. Em vista disso, esse artigo teve a finalidade de analisar a efetividade, em redução de riscos, de diferentes estratégias de hedge para o café arábica no Brasil. Foram Testadas quatro estratégias: não atuação em mercados futuros; cobertura completa; estratégia estática que incorpora o conteúdo informacional em médias condicionais, obtida pelo...

The São José Environmental Protection Area (EPA) in the State of Minas Gerais has a rich natural and historical patrimony. However, in spite of its value and of being a protection area since 1981, it has now suffering several degradations. In that sense, the major objective of this work is to value São José EPA with the purpose of supplying subsidies for the elaboration and attainment of public and private projects of preservation or sustainable exploration of the referred asset, as well as for public policy directed to its administration. As valuation method, it was used the contingent valuation through the approach of Hanemann (1984) and the bootstrapping method to obtain a monthly willingness-to-pay (WTP) per family of the municipal districts that...

O caso do ICMS Ecológico em Minas Gerais AgEcon Fernandes, Luciany Lima; Coelho, Alexandre Braganca; Fernandes, Elaine Aparecida; Lima, Joao Eustaquio de. The ecological ICMS was first used to distribute a share of the ICMS revenue in the state of Parana in 1991. This pioneer experience originated from counties’ claims which argued that their economies were harmed by land use restrictions, mainly because they were watershed protection areas or their territory was part of a conservation unit. Responding to these claims, the state government changed the ICMS allocation criteria, favoring those counties with added funds. In the Minas Gerais State, the Ecological ICMS was implemented in 1995 with the “Robin Hood Law”. The objective of this study was to evaluate the Ecological ICMS in Minas Gerais as an instrument for compensation and incentive. Results showed the creation of a conservation unit would compensate...

The main objective of this paper was to obtain an estimate for the industrial electricity demand in Minas Gerais in the period from 1970 to 2002. After identifying that the series were nonstationary, it was used the Cointegration approach, being estimated a Vector Error Correction Model (VEC Model). The results showed that both price and income elasticities are inferiors to the unit. The projections for period 2004/2008 indicate that the consumption of electricity should present superior taxes of growth to the observed ones in the decade of 90.

Ano: 2005 URL: http://purl.umn.edu/56746 DETERMINANTES DA ERRADICAÇÃO DA FEBRE AFTOSA NO BRASIL AgEcon Muller, Carlos Andre da Silva; Mattos, Leonardo Bornacki de; Lima, Joao Eustaquio de. Foot and mouth disease (FMD) has been a problem for the Brazilian livestock since the XIX century. Once it affects the livestock productivity and has always been a problem for the country exports due to the imposition of sanitary barriers. In 1992, when no state was free from FMD, the National Program for Eradication of FMD (PNEFA) was implemented. Since then good results has been obtained with control and eradication of the disease in some states. However, in other states the problem still persists. It is important to determine why some states have faced difficulties in reaching the status of free from FMD while others not. This work aimed to identify the factors which discriminate the populations of states free from FMD from those not free. The results...

Ano: 2007 URL: http://purl.umn.edu/43799 Transmissão de preços entre mercados regionais de carne de frango no Brasil AgEcon Mattos, Leonardo Bornacki de; Lirio, Viviani Silva; Lima, Joao Eustaquio de; Campos, Antonio Carvalho. Non-negligible transaction costs restrict the transmission of price shock between markets. The aim of this work was to analyze the effects of transaction costs on the spatial integration of the internal market for chicken meat, from 1998 to 2007. The applied methodology was based on the Threshold Cointegration Analysis. The results indicate the presence of significant barriers to the price transmission between the markets, existing probably due to the transaction costs. Prices are not very sensitive to eventual deviations of the long run equilibrium. It could also be noted that a relatively long period is necessary to eliminate price shocks, and the price transmission process is asymmetric.

In the Brazilian agriculture, there is a great diversity and heterogeneity of production systems that are subject to wide number of factors of risks. Although these risks cannot be completely eliminated, they can be minimized by adopting some strategies, as the diversification with agricultural and cattle activities. Based on the research historical results of the Paraná’s agriculture e with the measurement of the value-at-risk, this work aimed to analyze the volatility of the economic returns of integrated crop-beef cattle systems compared to systems characterized by grain cultivation or beef cattle specialization. As results, we observed that, in the short-term, the integrated crop-livestock system is the alternative that trends to generate better...

The Brazilian agricultural sector is characterized by a great diversity of production systems subject to a wide number of risk factors. These risks cannot be completely eliminated, but they can be minimized by the adoption of some strategies, such as diversification of agricultural and livestock activities. In this light, a comparative analysis, under operational and market risk conditions, of the financial viability of integrated crop-livestock systems, in relation to systems characterized by grain exploitation or specialized in livestock (beef cattle), was done. The methodology included data on farming in Paraná state, especially the in area of Guarapuava. Long term financial indicators were generated: net present value, internal return rate and...

The objective of this study was to analyze the average production functions and the frontiers production function to characterize the structure of the agricultural production technology. Using data of the agricultural census of 1995/96 regarding the mesorregião of the Triangulo Mineiro and Alto Paranaíba of the State of Minas Gerais the goal programming was used to calculate the parameters of the Cobb Douglas production functions. One of the main conclusions is the existence of significant differences in the level of productive efficiency and in the structure of the production technologies in this Mesorrregião, indicating the bias that is incurred when making decisions only based on the parameters of the average production function.

The aim of this paper is to check if there is a relation between the wheat prices of the Argentinian and the International market, if these markets are integrated in space. For that, it was used as time reference the period from January, 1994 to April, 2009. Unit root tests, Granger causality, Johansen cointegration, estimation of the impulse response function, decomposition of error variation and estimation and analysis of the error correction model were used. The results indicated that variations in the international prices of wheat were almost completely transmitted for the run long. However, it is not possible to affirm that the Argentinian and the International markets are perfectly integrated even if they have a higher transmission of prices This is...

The analysis of market integration of agricultural commodities based on price information are limited because the effects of transaction costs are not considered in the adjustment process. The main objective of this paper was to estimate the possible transaction costs impacts on market integration of beef cattle between the states of Minas Gerais and São Paulo. It was estimated a Threshold Vector Error Correction Model (TVEC model) using monthly price data for the period from January 1972 to August 2005. The results indicated the presence of threshold cointegration implying that transaction costs have important effect on the price adjustment process.

Ano: 2009 URL: http://purl.umn.edu/60821 EFICIÊNCIA TÉCNICA E DE ESCALA DAS COOPERATIVAS NO SETOR LÁCTEO AgEcon Ferreira, Marco Aurelio Marques; Jose Braga, Marcelo; Lima, Joao Eustaquio de. The advancement of investor-owned firms (IOF), mainly multinational ones, and the reduced participation of cooperatives in dairy production and processing in Brazil along the past few decades has been calling the attention of researchers. With the participation of 59 productive units, distributed over 9 states of the Brazilian territory, the objective of this work was to analyze the efficiency of the cooperatives in the dairy industry using the Data Envelopment Analysis (DEA). The results show that, in general, the cooperatives presented better performance in terms of scale rather than in terms of productive efficiency. This stimulates sectorial politicies that promote improvements in the use of the resources to obtain greater efficiency in milk processing.

The recent transformation in milk production was characterized by the reduction of the prices received by the producer and by the increase of the production and productivity. Facing this reality, this work has the objective to identify whether the option for informal commercialization of the milk was one of the alternatives for the small producers receiving better prices. It was used a logit model to measure the impact of production volume and price received over the probability of producers to opt to sell in informal markets. The results were compatible to what was expected, once the price received per milk litre affects positivelly and the volume production has a negative effect the probability of producers to sell his production at informal markets....

The main objective of this paper was to analyse the factors that influence deforestation in small rural farms of a colonization area in Brazil’s Amazon Region. It was used data from 138 small farms distribuited over the transamazonic road in the municipality of Uruará, PA. The data was collected during july and august of 2002. A Tobit model with sample selectivity with etimation in two stages (Heckman) was used. In the first stage, the probability of deforestation was explained mainly by the presence of cattle in the farm. In the second stage, the deforestation area was modeled as a function of various factors. The results showed that the main determinants of deforestation are the amount paid for lired labor, the distance from the main road, the number of...
