This paper performs comparative analysis of the non-radial Russell output technical efficiency measures of 13 Eastern European banking systems assuming a banking production with risk as an undesirable output and where output components can be negative. This is analysed utilizing three modelling...

In this paper we introduce a scale elasticity measure based on directional distance function for multi-output-multi-input technologies and explore its fundamental properties. Specifically, we derive necessary and sufficient condition for equivalence of the scale elasticity measure based on the...

The challenge of the econometric problem in production efficiency analysis is that the efficiency scores to be analyzed are unobserved. Statistical properties have recently been discovered for a type of estimator popular in the literature, known as data envelopment analysis (DEA). This opens up...

This paper investigates the effects of home country banking regulations on the performance of foreign banks in Luxembourg?s financial center. We control for the main regulatory indicators, such as capital requirements, private monitoring, official disciplinary power and restrictions on bank...

Presumably, foreign banks open subsidiaries and branches in Luxembourg to perform different tasks. This paper studies the balance sheet structure of banks in Luxembourg, testing for differences across groups and across periods. Non-parametric methods yield several findings. First, specialisation...
