This paper proposes a new testing approach for panel unit roots that is, unlike previously suggested tests, robust to nonstationarity in the volatility process of the innovations of the time series in the panel. Nonstationarity volatility arises for instance when there are structural breaks in...

This paper discusses two longstanding questions in growth econometrics which involve multiple hypothesis testing. In cross sectional GDP growth regressions many variables are simultaneously tested for significance. Similarly, when investigating pairwise convergence of output for $n$ countries,...

This paper used Monte Carlo simulations to analyze the small sample properties of cross-sectionally augmented panel unit root test (CIPS test). We considered situations involving two types of time-series heteroskedasticity (unconditional and ARCH) in the unobserved common factor and...

This study investigates the existence of regional convergence of per capita outputs in China from 1952–2004, particularly focusing on considering the presence of multiple structural breaks in the provincial-level panel data. First, the panel-based unit root test that allows for occurrence of...

Using PIRLS (Progress in International Reading Literacy Study) data, we investigate which countries' schools can be be classified as significantly better or weaker than Germany's as regards the reading literacy of primary school children. The `standard' approach is to conduct separate tests for...

This study tests the hysteresis hypothesis of unemployment in fourteen OECD countries by examining the stationarity of unemployment rates using several panel unit root tests. Empirical results show that the hysteresis hypothesis cannot be rejected for majority of the OECD when the tests are...

This study examines the real interest rate parity (RIP) hypothesis in the case of East Asian economies by taking China as foreign counterpart. Results obtained from panel unit root tests are in line with previous findings that are supportive of the hypothesis. The estimated half-life of the RIP...

Most studies that use classical unit-root tests in OECD countries support the unemployment hysteresis hypothesis. However, similar classical tests performed on US data yield mixed results, uncovering specification issues. This study uses a number of panel unit root tests, which are known to...

An alternative to using normally distributed random effects in modeling clustered binary and ordered responses is based on using a finite-mixture. This approach gives rise to a flexible class of generalized linear mixed models for item responses, multilevel data, and longitudinal data. A test of...

Aim of this study is to analyze the non-stationarity of real GDP levels using recently developed Carrion-i Silvestre et al. (2005) panel unit root test allowing different number of structural breaks in panel. For this purpose, this test is applied to panel data of per capita GDP of 20 high...
