This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken...

This paper analyses airline accidents data from 1927-2006. The fractional integration methodology is adopted. It is shown that airline accidents are persistent and (fractionally) cointegrated with airline traffic. Thus, there exists an equilibrium relation between air accidents and airline...

This study analyses the persistence in the international monthly arrivals to the Azores Islands using a model based on fractional integration and seasonal autoregressions. The estimated fractional differencing parameter gives an indication of the long run evolution of the series. We use both...

This article analyses the efficiency of French nuclear energy plants belonging to EDF-electricity of France from 2004 to 2008 with a DEA-Data Envelopment Analysis model. The <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" id="ILG0001" xlink:href="raec_a_892199_ilg0001.gif"/>-convexity model is used to investigate the technical efficiency of a representative sample of nuclear plants. The results...

This paper presents an efficiency assessment of selected OECD countries using a Slacks Based Model with undesirable or bad outputs (SBM-Undesirable). In this research, SBM-Undesirable is used first in a two-stage approach to assess the relative efficiency of OECD countries using the most...
