In many of his writings, lectures and talks Pedro Gil emphasized the wide variety of economic applications of Information Theory. In this paper, as a tribute to him, we aim to provide some insight into this topic, mainly referred to income inequality, industrial concentration and economic forecasting.

La adaptación de las titulaciones al EEES requiere cambios significativos en el diseño de los contenidos formativos y en la metodología docente, por lo que resulta especialmente interesante contar para esta tarea con la opinión de todos los colectivos afectados: empleadores, egresados y, en particular, de los estudiantes actuales. En este contexto,...

Empirical studies employ very different methods to identify the moments at which currency crises occur. In previous works we have shown that considerable variations exist between the crises indicated by each of them. In this work, we use a broad sample of these indicators as a dependent variable in one of the most frequently cited Early Warning Sys...

Las crisis cambiarias de las últimas décadas han originado dos corrientes en Economía Internacional, una orientada hacia la elaboración de modelos teóricos de crisis cambiarias y su contrastación empírica y otra centrada en las reformas de la Arquitectura Financiera Internacional. Ambas confluyen en un grupo de trabajos empíricos que tratan de expl...

The aim of this article is describing the main features of the degrees on Economics and Business in Spain prior to the European Higher Education Area (EHEA).

Given the relevance of the statutory audit, this paper examines the auditor's report of a sample of companies during several periods. The objective is to confirm the influence of certain factors on the auditor's opinion, and analyze the relation between those factors and the audit firm type. In order lo achieve this, several univariate tests are ca...

Dada la trascendencia de la auditoría de cuentas, el presente trabajo tiene por finalidad estudiar los informes de auditoría recibidos por un conjunto de empresas a lo largo de varios ejercicios, con el ánimo de comprobar si existen variables que hagan que una entidad sea más o menos propensa a obtener una determinada opinión, y si las mismas tiene...

Los estudios de modelizacion regional han adquirido una importancia creciente como consecuencia del aumento de las disponibilidades de informacion y la mayor sensibilidad hacia las politicas territoriales. En el caso de la realidad asturiana, nos enfrentamos a un entorno economico fuertemente afectado por la marcha de la economia nacional y en el q...

In the literature concerning the measurement of the Inequality with respect to a certain economical attribute (income, wealth, etc.), several measures have been established. Among them, the so-called «additively decomposable inequality indices» (containing the well-known Theil and normalized variance indices) are generally accepted because of their...

In order to answer the problem of quantifying the degree of unequalness among the individual shares in the distribution of income, several authors proposed and characterized the well-known additively decomposable measures of relative income inequality. In a previous paper, R. Pérez, C. Caso and M. A. Gil [Stat. Hefte 27, 227-237 (1986; Zbl 0651.621...

Havrda and Charvát (1967) and Daróczy (1970) introduced the nonadditive entropies of order α, each one of them can be regarded as a function defined on the class of distributions associated with a given population and quantifying, in a certain sense, the similarity between the uniform distribution and the considered one. When the population is fin...

In previous papers the problem of estimating the Gini-Simpson index of diversity for large populations has been considered by using random samplings with and without replacement, Nevertheless, the populations to which this estimation is usually applied (e.g., anthropoiogicai, ecological, linguistic and sociological populations) often arise naturall...

We introduce unbiased estimators of the mutual information between two random variables in stratified sampling with and without replacement from a finite population, when the mutual information is quantified in terms of the quadratic entropy. We then suggest posterior complementary studies in order to estimate such a characteristic in a suitable wa...

In a previous paper Gastwirth shows that a broad family of measures of inequality can be accurately estimated when the tax data are known in groups (more precisely, when we know the number of returns in each of several class intervals and their corresponding average income). In the present paper we show that some measures of the preceding family ca...

Durante los últimos quince años, la economía mundial ha experimentado un elevado número de crisis cambiarias. Este hecho ha impulsado una numerosa y creciente literatura empírica que ha tratado de explicar los principales determinantes e incluso buscar métodos que permitieran anticiparlas. Todos estos trabajos parten de un procedimiento para determ...
