    Abstract

    Analisou-se a elasticidade de transmissão de preços e a formação espacial entre as principais regiões produtoras de leite do Brasil, no período de 1997 a 2005, pela análise de co-integração, e pelo Modelo Vetorial de Correção de Erro (VEC). Os resultados evidenciaram que a variação de 1% nos preços recebidos pelos produtores de leite de Minas Gerais leva a uma variação de 0,38%, 0,72%, 0,93% e 0,26% nos preços em São Paulo, Rio Grande do Sul, Paraná e Goiás, respectivamente. Pela estimação do VEC os coeficientes do Paraná e São Paulo, em módulo, foram comparativamente maiores aos demais. São Paulo foi menos interdependente, indicando comportamento mais isolado no padrão de liderança preço. Verificou-se que, com o passar dos meses os preços de Minas Gerais, explica grande proporção da variabilidade dos preços de leite ao produtor dos estados, corroborando a importância relativa do estado na formação espacial de preços deste mercado. ----------------------------------------------It was analyzed elasticity of transmission of prices and the space formation enters the main milk producing regions of Brazil, in the period of 1997 the 2005, for the analysis of co-integration, and the Vectorial Model of Correction of Error (VEC). The results had evidenced respectively that the variation of 1% in the value receiveds for the producers of milk of Minas Gerais leads to a variation of 0,38%, 0.72%, 0.93% and 0.26% in the prices in São Paulo, Rio Grande do Sul, Paraná and Goiás. For the esteem of the VEC the coefficients of the Paraná and São Paulo, in module, had been comparativily bigger to excessively. São Paulo was less interdependent, indicating more isolated behavior in the leadership standard price. The relative importance of the state in the space formation of prices of this market was verified that, with passing of the months the prices of Minas Gerais, explain great ratio of the variability of the prices of milk to the producer of the states, corroborating.
