Funções de exportação e de importação para o Brasil

Abstract

This study attempts to give consistent estimates for export and import elasticities for Brazil, by groups of goods. A number of model specification are estimated and an econometric procedure for diagnostic testing and model selection is employed. The study detects that exports supply is price elastic and increases as installed capacity grows. Export demand aid import demand functions show lour price-elasticity' curd high income elasticity. Although elasticity pessimism can be discarded, unrestricted elasticity optimism is not supported by these findings.
