Abstract

Este trabalho procura determinar os impactos de diferentes opções de política comercial, sob pressuposições alternativas de retornos à escala e natureza da competição, nos segmentos industriais, com ênfase especial nas indústrias ligadas ao agronegócio. O modelo de equilíbrio geral aplicado, GTAPinGAMS, é usado para implementar as simulações. Os resultados sugerem que os ganhos de bem-estar tenham sido superiores no modelo que considera as imperfeições de mercado. As variações setoriais na produção, importações e exportações foram levemente diferentes em magnitudes e sinais, sob pressuposições alternativas de estruturas de mercados, e dependentes da política comercial implementada. As diferentes medidas de política comercial permitem o aproveitamento de economias de escala e a redução do markup na maioria das indústrias, com evidências nos efeitos de racionalização e procompetitivos.
