En este estudio se aborda la importancia de realizar un buen diagnóstico de la situación de un río con carácter previo a cualquier acción de restauración, ya que, si no, las soluciones serían parciales y no podrían aportar una solución a su globalidad. El río Guadarrama, afluente del río Tajo entre Toledo y Talavera de la Reina, se encuentra muy al...

Full-text available
In rural areas, depopulation is mainly due to a lack of economic and employment opportunities. In this context, the reservoirs already built can be a source of socioeconomic development based on tourism and outdoor leisure activities. The condition for this development to materialize is that reservoir management considers these activities. In Centr...
Article
Income inequality is becoming a growing concern, worldwide, with wage inequality being the root cause of its recent escalation. With the aim of adding to the knowledge on this subject, this paper focuses on the spatial dimension of the problem, an aspect which has received less attention in the literature. We identify the determinants of inequality...

The historical centre of the city of Toledo (Spain) was declared a World Heritage City by UNESCO in 1986. Since then, it has lost almost a quarter of its population in favour of the city outskirts, outside the city walls. There are a number of reasons for this population abandonment. Like many cities around the world which share the similar charact...
Article
Some of the most overlooked valuation systems in current literature are those based on expert algorithms. Yet these algorithms can form the basis of a good estimation of the value of real estate since they allow simple computational methods that use big data to be integrated with the appraiser’ own knowledge of the situation. The main usefulness of...

In the literature on modeling commodity futures prices, we find that the stochastic behavior of the spot price is a response to between one and four factors, including both short- and long-term components. The more factors considered in modeling a spot price process, the better the fit to observed futures prices—but the more complex the procedure c...

The close relationship between collateral value and bank stability has led to a considerable need to a rapid and economical appraisal of real estate. The greater availability of information related to housing stock has prompted to the use of so-called big data and machine learning in the estimation of property prices. Although this methodology has...

The aim of this article is to propose a new breakdown of the Gini inequality ratio into three components (within-group inequality, between-group inequality, and intensity of transvariation between groups to the total inequality index). The between-group inequality concept computes all the differences in salaries between men and women. The main cont...

The Consumer Price Indexes (CPI) are used in current economic systems to measure inflation. When constructing CPIs, however, official institutions have systematically overlooked the spatial dimension of elementary prices. Ignoring the fact that prices are collected at geographical locations implicitly implies considering prices as spatially indepen...

The private sector and financial regulators have improved their ability to monitor and control risk taking. The Basel II Accord binds credit institutions to revise the collateral values of their credit loans frequently and states that statistical methods may be used. Although valuation of residential properties has traditionally been based solely o...

There exists three ways of approaching real estate prices: the cost approach, the market data approach and the income capitalization approach. In this article, we propose an improvement of the market data approach that takes into account the spatial component. In particular, we propose a modified market data approach based on interpolation, being t...

The estimation of commercial property prices in a touristic city can be explored through spatial interpolation methods, but in the presence of small sample sizes, auxiliary stochastic processes that are correlated with the prices of commercial establishments are needed. The aim of this paper is to compare the various estimates of commercial establi...

Recent legislation in Spain states the revision of the mortgaged residential property value. This fact has become important since 2008 due to the fall in the average housing prices in Spain. Traditionally, residential properties valuation procedure is based on the comparison to the nearest property prices being necessary to consult human experts. T...

National and international investors have observed the real estate market in Spain closely over the last decade.

One of the main tasks of regional and environmental economics is to construct Environmental Quality Indexes for big cities. A standard method is to generate a single measure as a linear combination of several contaminants by applying Principal Component Analysis. Spatial interpolation is then carried out to determine pollution levels across the cit...

Article
A vast majority of the recent literature on spatial hedonic analysis has been concerned with residential property values, with only very few examples of studies focused on commercial property prices. The dearth of studies can be attributed to some of the challenges faced in the analysis of commercial properties, in particular the scarcity of inform...

Aware of the fact that the environment affects housing prices considerably, this paper proposes a Mixed Environmental Quality Index (MEQI) to be used in a hedonic framework. It has two main novelties. The first is the inclusion of objective (including noise) and subjective variables. The second refers to methodology and proposes the DP2 Pena Distan...

There exists a large literature on the problem of forecasting election results. But none of the published methods take spatial information into account, although there is clear evidence of geographic trends. To fill this gap, we use geostatistical procedures to build a spatial model of voting patterns. We test the model in three close elections and...

Countless examples of misleading forecasts on behalf of both campaign and exit polls affecting, among others, British, French, and Spanish elections could be found. This has seriously damaged their image. Therefore, procedures should be used that minimize errors, especially on election night when errors are more noticeable, in order to maintain peo...

The price of houses and its evolution in recent years is one of the issues that citizens and, of course, political and economic authorities are worried about. In most of the developed countries the mean price (per square meter) of houses in an area is estimated by a simple average of single prices from a sample of houses that does not take into acc...
