Última A importância da energia para o setor agropecuário: uma abordagem do modelo VECM AgEcon Alves, Yony Brugnolo; Costa, Gilberto Fernandes Da; Ribeiro, Joao Gabriel; Parre, Jose Luiz; Alves, Alexandre Florindo. O presente trabalho investigou, com as metodologias de causalidade segundo Granger e VECM, a relação entre o PIB Agropecuário brasileiro e as variáveis consumo de energia do setor, maquinário agrícola, rebanho bovino e produção de grãos no período de 1970 a 2005. O consumo de energia foi enfatizando devido à agropecuária ser produtora e consumidora desta. Os resultados apontam uma grande relação, no curto prazo, entre o PIB e o consumo de energia. Quando se considera o conjunto das variáveis encontrou-se evidência de causalidade segundo Granger, evidenciando a importância das variáveis selecionadas como variáveis explicativas do PIB agropecuário. --------------This study used Granger causality and VECM methodologies, to investigate the relationship between...

Ano: 2008 URL: http://purl.umn.edu/108096 First filter test of market power in Finnish food retailing sector AgEcon Niemi, Jyrki S.; Xing, Liu. Buyer power and competition policy in food supply chains has emerged as an important economic issue and a highly sensitive item on the policy agenda all around the world. Claims that large retailers and food companies are depressing farm prices because of their market power have been made in many countries around the world (Swinnen and Vandeplas, 2009). Arising concentration of retailer sector increases the concern of existence and gradual growth of buyer power in this sector. The key reason is that the growing buyer power may have the effect of considerably distorting both retail and producer competition, and eventually it may damage economic welfare. In Finland, the increased concentration of the retail sector, with fewer outlets and the growth of the...

The goal of this study is to investigate the price relationship of EU biofuel market with other main markets in both horizontal level and vertical level. We first carry out Granger causality between ethanol price of EU, USA and Brazil. Secondly, we use vecto error cointegration Mechnism (VECM) to test the relationship between three selected vegetable oil prices in EU to see the competive potential of EU rapeseed oil compared with imported crude palm oil and soybean oil as the feedstock of biodiesel. Evidence shows that there is a unidirectional Granger causation from both USA and Brazil to EU market. USA price of ethanol is the most influential among the three price series, and EU has the least influence on the contrary. It indicates that it is very...

Ano: 2008 URL: http://purl.umn.edu/6501 DOES EXCHANGE RATE MATTER TO AGRICULTURAL BILATERAL TRADE BETWEEN THE UNITED STATES AND CANAD? AgEcon Cho, Guedae; Kim, Mina; Koo, Won W.. This study examines the effects of the U.S.-Canada exchange rate on bilateral trade of agricultural goods between the two countries and on U.S. farm income. Special attention is given to agricultural trade between the two countries under the Canada - United States Free Trade Agreement (CUSTA). This study utilizes two time series models: the vector error correction model (VECM) and the vector moving average model (VMA) with quarterly time series data from 1983 to 2000. This study found that exchange rates have a significant impact on U.S. agricultural trade with Canada and that the exchange rate between the two currencies is weakly exogenous in the U.S. agricultural sector, indicating that it is not influenced by U.S. agricultural trade with Canada and...

Ano: 2002 URL: http://purl.umn.edu/23485 Making the world market price endogenous within the AGMEMOD modelling framework: an econometric solution AgEcon Listorti, Giulia; Esposti, Roberto. This paper aims at making the world price endogenous within the AGMEMOD modelling approach. This approach constructs country-level commodity market models where supply and demand sides are equalized on the basis of the observed domestic prices. These prices are endogenous as they depend (price transmission equation) on a EU key-price, which is, in turn, endogenously determined by the world price (price formation equation). The world prices, however, are assumed to be exogenous. To make the world price endogenous, we propose a system of equations where the EU key-price and the world price are simultaneously determined. This system of equations, written in a dynamic and error-correction form (VECM), substitutes the usual price-formation equation, while price...

Ano: 2008 URL: http://purl.umn.edu/6659 Cooperative vs. Non-Cooperative Spatial Competition for Milk in the Presence of Farm Marketing Cooperatives AgEcon Graubner, Marten; Koller, Ines; Salhofer, Klaus; Balmann, Alfons. Although important, the spatial dimension is often neglected in studies of market power and competition in agricultural markets. This paper investigates spatial competition for raw milk between dairies under the presence of marketing cooperatives. Since observed in reality, our model is based on uniform delivered pricing and overlapping market areas. We compare spatial cooperative price matching with non-cooperative Hotelling-Smithies conduct. Utilizing a vector error correction model we show that the observed low price transmission in Germany is in line with cooperative behaviour. This seems rational since it increases processors profits. The abolition of the quota system may increase price transmission.
