Abstract

Neste trabalho, é medida a evolução da memória de longo prazo da taxa de câmbio diária, Real contra Dólar dos Estados Unidos, no período de 1995 a 2004. Essa medição é realizada por meio da análise R/S clássica, com janela móvel de dados. O trabalho focaliza o abandono do regime de câmbio administrado em favor do de câmbio flutuante, ocorrido em 1999, identificando antipersistência da taxa de câmbio durante a vigência do primeiro regime e memória longa a partir do início da vigência do segundo regime. Mostra também evidência de memória longa para as volatilidades dos retornos das taxas analisadas.
