Abstract

A estimação da relação entre os custos unitários de trabalho e a taxa de desemprego no período 1954-1995 com base em dados anuais, através da abordagem de Johansen, permite-nos concluir que a variação dos custos unitários de trabalho é função decrescente da variação da taxa de desemprego e do erro de equilíbrio (entre a taxa de variação dos custos unitários de trabalho e a taxa de inflação) e função crescente da inflação externa, controlando para a instabilidade da Revolução de Abril de 1974. A taxa de desemprego não é significativa na relação de longo prazo, mas a sua variação é significativa na relação de curto prazo, o que está de acordo com a curva de Phillips modificada, no caso de existência de histerese da taxa de desemprego.
