Abstract

Este estudo tem por objetivo analisar a cadeia de carne bovina de corte no Brasil e determinar, empiricamente, se há poder de mercado na relação comercial entre produtores rurais e frigoríficos. Com este fim, procedemos em duas etapas. Primeiro, fazemos uma caracterização da estrutura da indústria, para concluirmos que, de fato, a estrutura se aproxima de um oligopsônio. Usando informação a priori sobre a produtividade marginal do boi gordo, e dados mensais por um período de 14 anos para o estado de São Paulo, encontramos evidência de poder de mercado moderado no setor. Além disso, o poder de mercado não aumentou em anos recentes, quando a concentração no setor aumentou substancialmente.
