Validade da curva J para a economia brasileira em um contexto linear e não linear da taxa de câmbio

Abstract

This work aims to empirical analysis of short and long-term impact on the trade balance of Brazil in response to exchange rate depreciation in the period between January 1990 and October 2015. This influence was analyzed for the main sectors of the flow trade between Brazil and the main economic partners, which are European Union, United States and Mercosul. The hypothesis of the J curve states that there is a negative relationship in the short term and positive in the long run between these variables. Empirical work on the validation of the J curve have reached divergent results. This study advances in relation to the existing literature in two ways: the methodology used and the breakdown of products present in the export/import of Brazil. We use the approach of cointegration via ARDL model and NARDL and border test Pesaran et al. (2001) and Shin (2014). The results do not demonstrate that the use of non-linear methodology entails in evidence for the validation of the curve J. The J curve was valid for some sectors of Brazil bilateral relationship with the United States and the Mercosul, the European Union was no sector found.
