In this paper, we test for the stationarity and sustainability of European Union budget deficits over the period 1971 to 2006, using a panel of thirteen member countries. Our testing strategy addresses two key concerns with regard to unit root panel data testing, namely (i) the identication of...

This paper investigates the extent of per-capita income convergence in regional integration initiatives. Panel unit root testing is performed on 28 regional groupings. There is evidence of convergence in South- South integration, but this might be taking place to the bottom.

Since both health expenditure and GDP are trending, this omission raise serious doubts on...

In this paper we test for existence of cointegration between health expenditure and GDP using data from 19 OECD countries for the period 1960-1995. Country-by-country and panel results based on the Johansen multivariate likelihood-based inference and a new panel test for cointegration rank are...
