Abstract

A adoção de novas técnicas de produção de ovos no Estado de São Paulo, na década de 60, desenvolveu facilidades que permitiram uma rápida expansão do tamanho do plantei avícola e da produtividade por ave. Em consequência, o consumidor passou a adquirir mais ovos a um preço real mais baixo por dúzia, enquanto que, por sua vez, os produtores de ovos sentiram um declínio nas margens de lucro. Além disso, houve períodos de instabilidade nos preços de ovos. Este estudo, que analisa o mercado de ovos para São Paulo, encontrou coeficientes de preços inelásticos, tanto para a função de oferta (0,15) como para a função de procura (-0,19). Estes resultados empíricos estão sugerindo o motivo por que distúrbios no mercado de ovos, no curto prazo, levam a preços inestáveis. Também ajudam a explicar a razão pela qual mudanças tecnológicas conduzem a um declínio secular no preço real de ovos.
