This study analyses cost and revenue inefficiencies for a sample of European railway companies. On the basis of a DEA model we calculate cost and revenue inefficiencies, decomposing them into inefficiencies of a technical or allocative type. It is observed that inefficiencies in revenues are...

Traditional efficiency measures neglect bank risk and, even when risk is accounted for, do not differentiate between the portion subject to managerial control (¿internal¿) versus the portion that is exogenous and is part of a changing environment (¿external¿). This paper proposes a new...

Increased competition and the attempts of European banks to increase their presence in other markets may have affected the efficiency and credit risk. The first of this aspects is based on the incentive to the banks to reduce cost in order to gain in competitiveness. The second is associated to...

The aim of this paper is to analyze the efficiency of the Spanish banking system forthe period since Spain's incorporation into the EC (1986) to the beginning of the Unit Marketin 1993. A new productivity analysis is justified by the deep changes experienced duringthese years in the banking...

The aim of this article is to analyze the financial-economic situation by sizes of Spanish firms. The results show that, not only the small size firms, but also the medium size firms, find more difficulties in their production organization than large firms. In fact, their human resources are...

The aim of this paper is to analyse the role of human capital in the productivity gains of the countries of the OECD in the period 1965-90, breaking down the productivity gains into technicalchange and gains in efficiency. For this purpose we use both a stochastic frontier production function...

The aim of this study is to analyse the efficiency in costs and in profits of the Spanish banking sector (SBS) in the period 1985-96 using a non-parametric approach. The results obtained show the existence of profit efficiency levels well below those corresponding to cost efficiency, alternative...

This paper shows the importance of the composition of production -productive specialization- and sector inefficiencies when evaluating efficiency in aggregate production. For this purpose, a new approach is proposed for obtaining efficiency scores which enables two components to be...

The aim of this study is to analyze labor productivity convergence in the countries of the OECD over the period 1965-90. A non-parametric frontier approach is used to calculate the Malmquist productivity index. By breaking it down, the contribution to the growth of labor productivity of...

The aim of this paper is to analyse the effect of automatic teller machines on the productivity, costs and profitability of the Spanish savings banks. After describing the importance of ATM in the Spanish payment system, the paper analyses the effects of ATM on the savings banks sector using...
