RT Journal Article T1 Unemployment persistence in Europe: evidence from the 27 EU countries A1 Caporale, Guglielmo Maria A1 Gil Alana, Luis A. A1 Trejo, Pablo Vicente AB This paper investigates unemployment persistence in the 27 EU member states by applying fractional integrationmethods to quarterly data (both seasonally adjusted and unadjusted) from 2000q1 to 2020q4. The obtainedevidence points to high levels of persistence in all cases. With seasonally adjusted data, a small degree of meanreversion is found in the case of Belgium, Luxembourg and Malta, but this evidence disappears under theassumption of weakly correlated disturbances. More cases of mean reversion are found instead when analysingthe unadjusted series. In particular, countries such as Belgium, France, Croatia, Italy, Luxembourg and Maltadisplay orders of integration significantly lower than 1. In addition, significant negative time trends are found inthe case of Bulgaria, Croatia, Malta and Romania, and a positive one for Luxembourg. Finally, the Covid-19pandemic had mixed effects, with (seasonal) persistence increasing in some countries whilst decreasing inothers and not changing in a minority of cases. On the whole, our results support the hysteresis hypothesis for theEuropean economies.
