Testing of Unit Root Cycles in the Swedish Economy

  • Luis A. Gil-alana
Article

Abstract

In this article we examine the existence of unit root cycles in 11 long Swedish macroeconomic time series. We use a version of the tests of Robinson (1994) that permits us to test this type of hypothesis, which is based on the Gegenbauer processes. The results show that, for most of the series, the unit root cycles occur approximately every six periods. However, in case of the GDP deflator and wage rates, first differences may be required before proceeding to the analysis of the cyclical structure.
