Cost and revenue inefficiencies in the european railways

REA Auditado

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 greater than those in costs, indicating that the study of inefficiencies in costs is only a partial analysis of the problem. Also, technical inefficiencies are greater than the allocative type.

Exploring the Spanish interbank yield curve

REA Auditado

The yield curve (a plot of interest rates as a function of maturity) plays an important role in the informative framework of the monetary policy, because it ties the short-end of the asset markets (where monetary policy is set through open market operations and lending facilities) to the long-end (where is generated most of the information relevant to economic decisions linked to investment and borrowing).

Using rough sets to predict insolvency of Spanish non-life insurance companies

REA Auditado

Insolvency of insurance companies has been a concern of several parties stemmed from the
perceived need to protect the general public and to try to minimize the costs associated to this problem
such as the effects on state insurance guaranty funds or the responsibilities for management and auditors.
Most methods applied in the past to predict business failure in insurance companies are techniques of
statistical nature and use financial ratios as explicative variables.

Comparing neural networks and efficiency techniques in non-linear production functions

REA Auditado

Non-linear production functions are common in economic theory and in real life, especially in cases with increasing and diminishing returns to scale but there are also contexts where an increase in one input implies a decrease in one output. The aim of this paper is to test how non-linearity affect estimations of technical efficiency obtained by ordinary and corrected least squares (OLS, COLS), data envelopment analysis with constant and variables returns to scale (DEAcrs, DEAvrs), stochastic frontier analysis (SFA) and by multilayer perceptron neural networks with backpropagation (MLP).

Factores determinantes del proceso de internacionalización: el caso de Castilla y León comparado con la evidencia española

REA Auditado

In this paper, a framework based on the eclectic paradigm of Dunning is used to provide some empirical evidence about the internationalisation process of firms in Castilla y León. Through the applicatioin of hierarchical analysis and other descriptive methodologies, it has been possible to reach some conclusions about which are the factors determing the major internationalisation decisions.

Institutos tecnológicos y política sectorial en distritos industriales: el caso del calzado

REA Auditado

The aim of this paper is to asses the impact of the Valencian Regional Govern industrial and technological policy. We focus our analysis in the shoe industry and pay special attention to the role played by the «Instituto Tecnológico del Calzado» (Shoe Technological Institute) as the main responsible of the implementation of the policy decisions for the shoe sector. In order to perform our study, we use data from a survey carried out among the manager of the main compnies, workers' representatives and industry experts.
