Unemployment Hysteresis: Attached or Mismatched?

open access: yesScientific 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

Analyzing the Efficient Market Hypothesis with the Structural Break and Nonlinear Unit Root Tests: An Application on Borsa Istanbul

open access: yesEkoist Journal of Econometrics and Statistics, 2022
The literature on finance defines the concept of an efficient market as a market where information about securities is instantly reflected in prices. Investors who trade on efficient markets cannot obtain abnormal returns.

UNIT ROOT TESTS WITH WAVELETS [PDF]

open access: yesEconometric Theory, 2010
This paper develops a wavelet (spectral) approach to testing the presence of a unit root in a stochastic process. The wavelet approach is appealing, since it is based directly on the different behavior of the spectra of a unit root process and that of a short memory stationary process. By decomposing the variance (energy) of the underlying process into

High Persistence and Nonlinear Behavior in Financial Variables: A More Powerful Unit Root Testing in the ESTAR Framework

open access: yesMathematics, 2021
In this study, we consider the hybrid nonlinear features of the Exponential Smooth Transition Autoregressive-Fractional Fourier Function (ESTAR-FFF) form unit root test.

On the Robustness of Unit Root Tests in the Presence of Double Unit Roots [PDF]

open access: yesJournal of Time Series Analysis, 2000
We examine some of the consequences on commonly used unit root tests when the underlying series is integrated of order two rather than of order one. It turns out that standard augmented Dickey-Fuller type of tests for a single unit root have excessive density in the explosive region of the distribution.

Examination of Unemployment in the Framework of Hysteresis and Natural Rate in OECD Countries: Evidence from Alternative Panel Unit Root Tests

open access: yesEkoist 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 unit roots with stationary covariates [PDF]

open access: yesJournal of Econometrics, 2000
We derive the family of tests for a unit root with maximal power against a point alternative when an arbitrary number of stationary covariates are modeled with the potentially integrated series. We show that very large power gains are available when such covariates are available.
