Missing Values in Panel Data Unit Root Tests
Econometrics, 2022 Missing data or missing values are a common phenomenon in applied panel data research and of great interest for panel data unit root testing. The standard approach in the literature is to balance the panel by removing units and/or trimming a common time ...

Panel Unit-root Tests for Heteroskedastic Panels
The Stata Journal, 2018 In this article, we describe the command xtpurt, which implements the heteroskedasticity-robust panel unit-root tests suggested in Herwartz and Siedenburg (2008, Computational Statistics and Data Analysis 53: 137–150), Demetrescu and Hanck (2012a, Economics Letters 117: 10–13), and, recently, Herwartz, Maxand, and Walle (2017, Center for European ...

Panel unit-root tests with structural breaks
The Stata Journal, 2022 In this article, we introduce a new community-contributed command called xtbunitroot, which implements the panel-data unit-root tests developed by Karavias and Tzavalis (2014, Computational Statistics and Data Analysis 76: 391–407). These tests allow for one or two structural breaks in deterministic components of the series and can be seen as panel ...

A Monte Carlo study on the size and power of panel unit root tests: Limitations in small data sets
Croatian Operational Research Review, 2023 The aim of this paper is to explore the properties of various panel unit root tests in terms of their power and size regarding different panel data structures, with a special focus on small data samples.

Unemployment Hysteresis: Attached or Mismatched?
Scientific Annals of Economics and Business, 2021 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

Reflections on “Testing for Unit Roots in Heterogeneous Panels”
SSRN Electronic Journal, 2023 This article is our personal perspective on the IPS test and the subsequent developments of unit root and cointegration tests in dynamic panels with and without cross-section dependence. In this note, we discuss the main idea behind the test and the publication process that led to Im, Pesaran and Shin (2003).

Ekoist Journal of Econometrics and Statistics, 2021 Unemployment continues to be one of the important macroeconomic problems, its negative effects are not only seen at the economic level, but also in all societies at the social level. According to December 2020 data, the unemployment rate among the member

Testing for a unit root in panels with dynamic factors [PDF]
Journal of Econometrics, 2003 This paper studies testing for a unit root for large n and T panels in which the cross-sectional units are correlated. To model this cross-sectional correlation, we assume that the data is generated by an unknown number of unobservable common factors.

Unit roots: identification and testing in micro panels [PDF]
Working Paper Series, 2005 We consider a number of unit root tests for micro panels where the number of individuals is typically large, but the number of time periods is often very small. As we discuss, the presence of a unit root is closely related to the identification of parameters of interest in this context.
