More powerful panel data unit root tests with an application to mean reversion in real exchange rates
TLDR
In this paper, the authors show that more powerful variants of commonly applied unit root tests are readily available and that power gains persist when the modifications are applied to bootstrap procedures that may be employed when cross-correlation of a rather general sort among individual panel members is suspected.Abstract:
Unit root tests, seeking mean or trend reversion, are frequently applied to panel data. We show that more powerful variants of commonly applied tests are readily available. Moreover, power gains persist when the modifications are applied to bootstrap procedures that may be employed when cross-correlation of a rather general sort among individual panel members is suspected.

Econometric Analysis of Panel Data
TL;DR: In this article, the authors proposed a two-way error component regression model for estimating the likelihood of a particular item in a set of data points in a single-dimensional graph.

A Simple Panel Unit Root Test in the Presence of Cross Section Dependence
TL;DR: In this paper, a simple alternative test where the standard unit root regressions are augmented with the cross section averages of lagged levels and first-differences of the individual series is also considered.

A simple panel unit root test in the presence of cross-section dependence
TL;DR: In this paper, a simple alternative where the standard ADF regressions are augmented with the cross section averages of lagged levels and first-differences of the individual series is proposed, and it is shown that the individual CADF statistics are asymptotically similar and do not depend on the factor loadings.

Estimation and Inference in Large Heterogeneous Panels with a Multifactor Error Structure
TL;DR: In this article, the authors proposed a new approach to estimation and inference in panel data models with a multifactor error structure where the unobserved common factors are correlated with exogenously given individual-specific regressors, and the factor loadings differ over the cross-section units.

TL;DR: In this article, the causal relationship between energy consumption, carbon dioxide emissions, economic growth, trade openness and urbanization for a panel of new EU member and candidate countries over the period 1992-2010 was investigated.

Testing for unit roots in heterogeneous panels
TL;DR: In this article, a unit root test for dynamic heterogeneous panels based on the mean of individual unit root statistics is proposed, which converges in probability to a standard normal variate sequentially with T (the time series dimension) →∞, followed by N (the cross sectional dimension)→∞.

Unit root tests in panel data: asymptotic and finite-sample properties
TL;DR: In this article, the authors consider pooling cross-section time series data for testing the unit root hypothesis, and they show that the power of the panel-based unit root test is dramatically higher, compared to performing a separate unit-root test for each individual time series.

A Comparative Study of Unit Root Tests with Panel Data and a New Simple Test
G. S. Maddala,Shaowen Wu +1 more
TL;DR: The Im-Pesaran-Shin (IPS) test as discussed by the authors relaxes the restrictive assumption of the LL test and is best viewed as a test for summarizing the evidence from independent tests of the sample hypothesis.

Efficient Tests for an Autoregressive Unit Root
TL;DR: In this paper, a modified version of the Dickey-Fuller t test is proposed to improve the power when an unknown mean or trend is present, and a Monte Carlo experiment indicates that the modified test works well in small samples.

The overvaluation of purchasing power parity
TL;DR: This article showed that no evidence against the random walk null can be found in panels of up to 64 real exchange rates, which cannot be attributed to low power, as there is ample power in panels with this size to reject the unit-root null.
