This paper develops an index for comparing the productivity of groups of operating units in cost terms when input prices are available. In that sense it represents an extension of a similar index available in the literature for comparing groups of units in terms of technical productivity in the...

Using the stochastic frontier analysis model, we estimate TFEE (total-factor energy efficiency) scores for 47 regions across Japan during the years 1996–2008. We extend the cross-sectional stochastic frontier model proposed by Zhou et al. (2012) to panel data models and add environmental...

During the last years, we have observed a conceptual change in the management and structure of Italian airport sector because of the privatization process. In many cases, it has been accompanied by a process of partial or total privatization of services and infrastructures. The main purpose of...

This paper investigates the performance of information technology (IT) investments in a sample of 15 Tunisian banks over the period 1998–2009. We employ the standard Stochastic Frontier Approach on panel data to generate estimates of cost efficiencies. The study is enhanced by a comparison...

We measure eco-efficiency of an economy by means of an augmented Leontief input-output model extended by constraints for primary inputs. Using a multi-objective optimization model the eco-efficiency frontier of the economy is generated. The results of these multi-objective optimization problems...

Recent discussions on the definition of growth in terms of welfare beyond GDP suggest that it is of urgent need to develop new approaches for measuring the economic performance of the firms and national economies. The new concepts should take into account simultaneously economic as well as...

Data envelopment analysis is used to examine inter-temporal and peer group airline efficiency. Results for the US for 1985–2006 indicate that airline performance is converging over time. In particular, airlines inter-temporal inefficiency peaked earlier and then converged. Furthermore,...

The paper explores links between the operating performance of 30 airlines in the US and corporate governance. Initially data envelopment analysis is used to assess the relative efficiency of airlines and to investigate the contribution of inputs and outputs that affect technical efficiency....

In the last decade, the use of public service obligations (PSO; regulation and/or subsidies) in air transport to European remoter regions has substantially increased. However, there is significant heterogeneity between different regions in Europe with respect to the provision of PSO operations...

Previous studies of the role of regional airports in the Spanish economy have focused on calculating efficiency using air traffic as the output and airport infrastructure data as the input. We present an alternative quantitative analysis based upon the geographical structure within the airport's...
