Abstract

Tendo como escopo central demonstrar uma estimação da função lucro trans-logarítmica, o presente artigo, a partir de uma amostra de propriedades de dedicadas à avicultura de postura também calcula elasticidades de substituição entre os fatores produtivos. A amostra utilizada, coletada numa pesquisa de campo, em 2002, envolve propriedades dos estados de São Paulo, Minas Gerais e Paraná. Recorrendo à dualidade entre a função lucro e a função custo foi possível calcular as elasticidades em diferentes critérios, como o de Allen, o de Morishima e pela medida de Elasticidade Sombra. Constatou-se, em correspondência, uma oferta sensível à variações no preço do produto (ovos) e à oscilações nos preços dos insumos. --------------------------------------------------This paper presents an estimation of translog profit function for eggs farmer’s sample in Brazil. In the same time, from the information of the translog estimation had been calculated coefficients of substitution elasticity between production factors in this activity. The sample was collected in 2002 in the three major Brazilian states in eggs production: Sao Paulo, Minas Gerais and Parana. Utilizing the duality theory, between profit function and cost function, was possible calculate substitution elasticity over different measures, like Allen, Morishima and Shadow elasticity. Results corroborate, in consistency, the supply responding to changes in market price as well as input prices.
