This research is devoted to analysis of efficiency estimation in presence of spatial relationships and spatial heterogeneity in data. We presented a general specification of the spatial stochastic frontier model, which includes spatial lags, spatial autoregressive disturbances and spatial...

The welfare consequences of airline mergers have been analyzed almost exclusively in terms of ticket price. However, when flight frequency decisions are endogenized in a model,we can estimate measures of the relative importance of price and flight frequency. Hence, in a merger analysis, we can...

This paper is devoted to econometric analysis of broadband adoption efficiency in EU member states. Stochastic frontier models are widely used for efficiency estimation. We enhanced the stochastic frontier model by adding a spatial component into the model specification to reflect possible...

Aim: This paper aims to attract attention to the "green airport" term that is basically related with environmental legislations.Design / Research methods: A Data Envelopment Analysis (DEA) model is introduced to assess the efficiency of 22 airports in Turkey with the definition of undesirable...

This paper examines the total factor productivity of 28 Italian airports during 2000–2006 using non-parametric estimation methods. Moreover, non-parametric inference and hypothesis test on the Malmquist index and its two main components, efficiency and technological change, have been carried...
