O efeito fronteira das regiões brasileiras: uma aplicação do modelo gravitacional

Abstract

This paper analyzes the border effect for Brazilian goods market and its regions in 1999. The border effect indicates the bias for domestic trade compared with international trade. This effect was quantified empirically by using cross-sectional data in a gravitational model for

twenty-six Brazilian states plus the Federal District and forty other countries. Despite Brazil's involvement in commercial opening in the 90's, as well as important regional trade agreements such as Mercosul, we noticed that Brazil and some of its regions have high crossborder

costs. The finding results of this equation suggest a trade 33 times higher between Brazilian states than the international trade of these states. Regarding each Brazilian region, the border effect found for intra-national trade among Northeast and North regions is

significantly higher than the border effect for Southeast and Southern regions.
