We employ a linear unit root test as well as a nonlinear two-regime Threshold Autoregressive (TAR) unit root test to determine whether inflation differentials in the Eurozone during the period 1970-2009 were persistent or transitory. The results imply that inflation rate differentials in the...

This paper tests the existence of persistent inflation rate differentials in the euro area by employing linear as well nonlinear unit root tests. Besides linear unit root tests, a two-regime threshold unit root test examines the conjecture that inflation rate differentials follow a nonlinear...
