This paper examines the stationarity of real GDP per capita for 27 OECD countries during the period 1950 to 2004. Using ADF unit root test on single time series, it is found that real GDP per capita series of most OECD countries have unit root. This outcome, however, might be due to the...

We propose a nonlinear heterogeneous unit root test for testing the null hypothesis of unitroots processes against the alternative that allows a proportion of units to be generated by globally stationary ESTAR processes and a remaining non-zero proportion to be generated by unit root processes....

Inflation differentials in the Euro area are mainly due to a sustained divergence of wage developments across the Euro area, and narrower differences in labour productivity growth (Alvarez et al., 2006). We investigate convergence of inflation using unit labour cost (ULC) growth and applying...

A panel data set for six countries (Czech Republic, Hungary, Poland, Romania, Slovakia, and Slovenia) is used to estimate money demand with panel cointegration methods over the recent disinflation period. The basic money demand model is able to convincingly explain the long-run dynamics of M2 in...
