This paper examines the stationarity of carbon dioxide (CO2) emissions per capita for a set of 36 countries covering the period 1870-2006. We employ recently developed unit root and stationarity tests that allow for the mean reverting process to be nonlinear and take into account cross sectional...

Large regional unemployment disparities are a common feature of the labor market in many countries. This study deals with the question whether regional unemployment disparities in western Germany widen, become narrower or remain constant over time. It examines the hypothesis of convergence for...

This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence...

The goal of this paper is to investigate the validity of PPP for a heterogeneous group of 12 transition countries with respect to dollar and euro. The analysis relies on monthly data frequency covering the period of 1994-2008. The first generation of panel unit root tests is based on the...

This paper develops a simple panel unit-root test that accommodates cross-sectional dependence among variables and smooth structural changes in deterministic components. The proposed test is the simple average of the individual statistics constructed from the breaks and cross-sectional...

This paper proposes a new simple panel unit-root test by extending the cross-sectionally augmented panel unit-root test (CIPS) developed by Pesaran et al. (2013) to allow for smoothing structural changes in deterministic terms, approximated by a Fourier series. The proposed statistic is the...

We investigate whether recently high U.S. house prices are justified by fundamental factors. The standard unit root and cointegration tests with aggregate data indicate that house rent is the only fundamental which has the same order of integration as the price, but these two variables are not...

This paper proposes a panel unit root test for micropanels with short time dimension (T) and large cross section (N). There are several distinctive features of this test. First, the test is based on a panel AR(1) model, which allows for cross-sectional dependency, which is introduced by the...

The African Union advocates the creation of a monetary union in stages for the entire continent starting with each of the different sub-regions. Building from that, the Southern African Development Community has, among its goals, the creation of a monetary union for its member states. However,...
