Introduction to measures of inequality and concentration in tourism

There are many statistical measures available in the literature for the analysis of inequality and concentration. The most common measure in this field is the Gini index (Roselló Nadal et al.,2004), which is associated to the Lorenz curve. Both were developed at the beginning of the 20th century: the Lorenz curve in 1905 and the Gini index in 1914 (Giorgi,!1993). A revision of recent applications of these measures in the field of tourism can be found in Cisneros Martín and Fernández Morales (2015)and Duro (2016)

Higher Order Supersymmetric Truncated Oscillators

We study the supersymmetric partners of the harmonic oscillator with an infinite potential barrier at the origin and obtain the conditions under which it is possible to add levels to the energy spectrum of these systems. It is found that instead of the usual rule for non-singular potentials, where the order of the transformation corresponds to the maximum number of levels which can be added, now it is the integer part of half the order of the transformation which gives the maximum number of levels to be created.Comment: This article is a natural continuation of arXiv:1603.05173 and arXiv:1310.562

New accommodation models in city tourism: The case of Airbnb in Málaga

Tourism is one of the fields where collaborative consumption has arrived with more intensity. Although the emergence of Airbnb in the city tourism market has helped increase the number of tourists in most of the cases, it also poses some problems, like the gentrification in central and historic areas, the rising of tourist pressure, or some regulation and legal issues. The main findings of this research reveal that Airbnb supply in the city of Málaga shows a very high rate of growth. The spatial pattern of the Airbnb supply is highly concentrated in the city centre. A similar pattern is exhibited by the hotel supply, with only slight differences. Measures of tourist pressure like the number of Airbnbn accommodations per inhabitant or the density of accommodations by ha are found to be similar to that in Barcelona.Universidad de Málaga.

Seasonal concentration of cruise tourism in the Mediterranean

This research delves into analyzing the seasonality of cruise tourism in the Mediterranean by using the decomposition of the Gini index, used in the field of cruise tourism for the first time in literature. This study specifically used the decomposition to evaluate the contribution degree of each port to the global seasonal concentration of each Mediterranean region. Moreover, a cluster analysis technique (bootstrapped bagged clustering) was applied to classify the ports into homogeneous groups according to their seasonal patterns given the significant heterogeneity revealed in the major regions of the Mediterranean. The methodology applied can serve as a control and monitoring tool for measuring seasonal concentration levels in cruise tourism, allowing for policies against seasonality to be tailored in the cruise tourism segment.Universidad de Málaga.
