The stationary properties of natural gas consumption are essential for predicting the impacts of exogenous shocks on energy demand, which can help modeling the energy-growth nexus. Then, this paper proposes to investigate the panel unit root proprieties of natural gas energy consumption of 48...

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...

In this paper we propose a new test statistic that considers multiple structural breaks to analyse the non-stationarity of a panel data set. The methodology is based on the common factor analysis in an attempt to allow for some sort of dependence across the individuals. Thus allowing for...
