This study uses stochastic frontier analysis for estimating efficiencies of railways systems in European countries. We consider railways as a system which uses its infrastructure (length of lines worked, numbers of cars and wagons, staff strength) and a scale of market (number of habitants and...

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...

This paper aimed at a statistical analysis of competition for tourists between regions within Baltic states (Estonia, Latvia, Lithuania) and estimation relative efficiency levels of regions. We apply a modern approach called Spatial Stochastic Frontier and corresponded to spatial modification of...

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 Romanian financial market has passed in the last years through a large “maturating” and consolidation process which has created an unfinished architecture, harmonising step by step with the capital markets from European Union. One possible way to analyse the empirical characteristics of...

Many financial studies are based on the efficient capital markets hypothesis. In this context, testing the existence of this concept becomes an interesting field of study for the emerging capital market. The aim of this paper is to enlighten the difficulties of portfolio construction in a...

This study deals with estimation of European airports' efficiency values and their interrelation with a level of competition pressure for passengers among airports. In this paper we present a new adaptive definition of airport's catchment area. Using this definition we develop an indicator of a...
