In this paper we test the stationarity properties of the consumption-income ratio for a sample of 14 European Union countries over the period 1960-1999 utilizing recent advances in panel unit root and asymmetric unit root tests. We find that a failure to take account of asymmetries, would imply...

In this paper, we apply panel cointegration tests and estimation techniques to obtain efficiency measures when it is uncertain whether the underlying technological relationship is structural or spurious due to possible non-stationarity of the data. We illustrate the dangers of efficiency...
