Impacto de las instalaciones sobre el desempeño del sector hotelero español

El sector hotelero, productor primario del sector turístico, tiene una gran relevancia para la economía española. Sin embargo, está inmerso en un entorno global y está sujeto a fuertes cambios. Por lo tanto, ante esta situación de incertidumbre, el sector hotelero debe identificar y analizar cuáles son sus fuentes de ventaja competitiva para mejorar su competitividad futura y adaptarse correctamente a los retos de su entorno. En este estudio, realizado desde la Teoría de Recursos, se argumenta la importancia de las instalaciones hoteleras y se ofrecen múltiples razones para que sean consideradas fuente de ventaja competitiva para mejorar la capacidad de competir de los hoteles. De esta forma, en esta investigación empírica, se realiza un estudio descriptivo del nivel de desarrollo de las instalaciones hoteleras y se demuestra que tienen un impacto significativo sobre el desempeño que alcanzan los hoteles de tres a cinco estrellas de toda España.

Technical efficiency in the retail food industry: the influence of inventory investment, wage levels, and age of the firm

The objective of this paper is to estimate technical efficiency in retailing; and the influence of inventory investment, wage levels, and firm age on this efficiency. We use the output supermarket chains’ sales volume, calculated isolating the retailer price effect on its sales revenue. This output allows us to estimate a strictly technical concept of efficiency. The methodology is based on the estimation of a stochastic parametric function. The empirical analyses applied to panel data on a sample of 42 supermarket chains between 2000 and 2002 show that inventory investment and wage level have an impact on technical efficiency. In comparison, the effect of these factors on efficiency calculated through a monetary output (sales revenue) shows some differences that could be due to aspects related to product prices.

A logic-mathematical point of view of the truth: Reality, perception, and language

In this article, the authors propose a theory of the truth value of propositions from a logic-mathematical point of view. The work that the authors present is an attempt to address this question from an epistemological, linguistic, and logical-mathematical point of view. What is it to exist and how do we define existence? The main objective of this work is an approach to the first of these questions. We leave a more thorough treatment of the problem of existence for future works.
