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...

The relationship between publically reported weekly grid premiums and discounts for specific carcass characteristics and the percentage of those characteristics reflected in total weekly slaughter volume (i.e., proportional slaughter volume) is investigated. Granger Causality and multi-lag VAR models were used to investigate if grid premiums and discounts were efficiently transmitting market signals to producers with respect to carcass quality attributes. The empirical evidence indicates that there is little evidence to suggest that grid prices are providing efficient price signals to buyers and sellers with respect to market valuation of desirable and undesirable beef carcass characteristics.

Modern agricultural commodity markets are simultaneously governed by a physical and a financial market element. Whether financial “index trading” activity influences price levels on the futures markets has been investigated by empirical studies using Granger Causality Analysis. A critical review of these studies reveals inconclusive results. Based on sensitivities of the method, reasons for limited interpretability of results may be omitted determinants of financial trading activity, failure to consider the informational efficiency of markets, time-varying and feedback effects of boundedly rational heterogeneous trading strategies and limitations in specifying adequate theoretical variables from existing data.
