This paper investigates the empirical significance of the unemployment problem whether it is structural or temporary on the basis of region-based, income-based and aggregate classifications of different countries for the yearly data from 1991 to 2018. In the first part of the paper, we examine the stationary position of unemployment series by way of using individual unit-root tests. Since the series are possibly subjected to the structural breaks, we also use additional approaches in which the effects of the break dates are checked in the analysis. Furthermore, we compare the initial findings of univariate unit-root tests along with panel unit-root testing procedures to critically assess the statistical validity of the hysteresis hypothesis in unemployment for given samples. The empirical findings imply that we cannot reject the hysteresis hypothesis for different classifications of the countries against the alternative of a natural rate even in the presence of structural breaks.

失业滞后：依附还是错配？

本文根据 1991 年至 2018 年的年度数据，根据不同国家的地区分类、收入分类和总量分类，研究失业问题的实证意义，无论是结构性的还是暂时性的。在论文的第一部分，我们通过使用单个单位根检验来检查失业序列的固定位置。由于该系列可能受到结构性中断的影响，我们还使用其他方法在分析中检查中断日期的影响。此外，我们将单变量单位根检验的初步结果与面板单位根检验程序进行比较，以批判性地评估给定样本失业中滞后假设的统计有效性。
