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 aim of this work is to characterize milk producers in Southwestern Paraná. It has been considered technical, technological, managerial, economic and social aspects. 202 producers have been interviewed, grouped into three distinct clusters, according to productivity levels. As results, milk producers in the region presented, on average, superior indicators when compared to data in Paraná, ratifying better organization and productive system in the region. Relevant differences among producers with different productivity levels could be pointed out. Low-productivity producers, in general, are more engaged in rural work, produce low volume of milk and work in milk activity for longer time, which can indicate path dependency. Besides that, higher percentage... |
