Abstract

O principal objetivo deste trabalho é o de verificar a importância da política de crédito agrícola, especialmente os créditos de investimento e de custeio, bem como da educação para o produto per capita rural. Juntamente verificamos de forma indireta duas variáveis estruturais importantes que podem afetar a produtividade rural que são as cooperativas e as ferrovias. Como inovação estimamos um modelo econométrico em painéis de dados dos municípios parananenses para o período 1999 – 2003. Nos testes econométricos verificamos que não existe diferença substancial entre os efeitos fixos e aleatórios, no entanto estes modelos assumem a priori que o crédito agrícola e o nível educacional são estritamente exógenos. Como existe a possibilidade de efeito causalidade inversa, optamos por estimar um modelo dinâmico em painel de dados, onde exige-se somente a condição de que as variáveis explicativas não estejam correlacionadas com a condição inicial. Nossas estimativas demonstraram que somente o crédito agrícola para custeio possui exogeneidade contemporânea e explica grande parte das variações no produto per capita rural. A presença de cooperativas e ferrovias também demonstrou não ser significante no modelo dinâmico. Acreditamos que a insignficância encontrada no modelo dinâmico da variável nível de escolaridade dos munícipes como um todo, deve-se a proxy utilizada. ------------------------------------------------------------ The main objective of this paper is to verify the importance of the agricultural credit in the form of investment and production financing as well as the education level on rural per capita production. Two other variables are considered in this paper as representing structural conditions which are the presence of railroad and cooperatives. As innovation of this paper is use of panel data econometrics for the Parana counties over the period of 1999-2004. Our econometrics test regarding random and fixed effects showed to be significant for all variables tested, however, they have embodied the strict exogeneity condition. Therefore, we opted for a dynamic estimation that takes into consideration only contemporaneous exogeneity. The final result found was that only the agricultural credit related the production financing is important for rural per capita production. In our tests neither railroad, cooperatives nor education level showed to be significant dynamically. The education level insignificance may be due to the proxy used in this paper, since we do not observe rural education level.
