Abstract

Após a abertura comercial em 1998, grandes mudanças ocorreram no comércio exterior nacional devido sucessivos choques cambiais aos quais a economia foi exposta. A literatura de referência sugere que grandes choques na taxa de câmbio induzem mudanças persistentes na relação entre a taxa de câmbio e o comércio. Este fenômeno é conhecido por histerese. Desta forma, o objetivo deste trabalho é evidenciar a existência de histerese no comércio internacional brasileiro, com interesse particular no setor agrícola. Os resultados indicaram evidências de histerese simples na taxa de câmbio e nas importações brasileiras, e de histerese fraca no setor agrícola e nas exportações. Conclui-se que a mudança de regime cambial em 1999 e a unificação cambial em 2005 promoveram efeitos de histerese, sobretudo nas importações brasileiras e no setor agrícola. After the commercial opening in 1998, significant changes in the external trade occurred due to the exchange shocks for which the economy was exposed. The reference literature suggests that significant shocks in the exchange rate induce persistent changes in the relationship between the exchange rate and the international trade. Such phenomenon is called hysteresis. In this sense, the objective of this work is to verify the existence of hysteresis in the Brazilian international trade with special interest in the agricultural sector. The results indicate existence of simple hysteresis in the exchange rate and in the Brazilian imports as well weak hysteresis in the agricultural sector and in the Brazilian exports. It is possible to conclude that the change of exchange regime in 1999 and the exchange unification in 2005 leaded effects of hysteresis specially in the Brazilian imports and in the agricultural sector.
