According to the test results, 37 developed and developing countries are in a stationary process. The Panel KSS unit root tests with a Fourier function have shown long-term evidence in favour of 37 countries. According to the results of the analysis, it is concluded that the unemployment series are stable in all countries. This result is important in terms of the determination of long-term analysis in developed and developing countries.eninfo:eu-repo/semantics/closedAccessUnemployment HysteresisNatural Rate HypothesisSequential Panel Selection MethodPanel KSS Unit Root TestArticle176-201224N/A
