Asymmetric Behaviour of Spanish Regional House Prices: A Multivariate Approach
(Springer, 2008) Rodríguez Aragón, Francisco; Larraz Iribas, Beatriz; Alfaro Navarro, José Luis
In connection with the housing market, which is presently raising a great deal of concern among the general public, this paper investigates regional housing prices in Spain using variable co-integration techniques. It analyzes the asymmetric behavior in real house prices among the Spanish regions focusing on the study of the long-term relationships over time. This paper raises an important question of the national averages masking important regional asymmetries. Results indicate evidence of cointegration, which suggests a broad grouping of regions based on physical proximity or similar economic characteristics.

Building an Environmental Quality Index for a big city: a spatial interpolation approach with DP2
(MPRA, 2008) Chasco Yrigoyen, Coro; Montero Lorenzo, José María; Larraz Iribas, Beatriz
The elaboration of Environmental Quality Indexes (EQI) for big cities is one of the main topics in regional and environmental economics. One of the usual methodological paths consists of generating a single measure as a linear combination of several air contaminants applying Principal Component Analysis (PCA). Then, as a final step, a spatial interpolation is carried out to determine the level of contamination across the city in order to point out the so-called ‘hot points’. In this article, we propose an alternative approach to build an EQI introducing some methodological and practical novelties. From the point of view of the selection of the variables, first we will consider noise -joint to air pollution- as a relevant environmental variable. We also propose to add ‘subjective’ data -available at the census tracts level- to the group of ‘objective’ environmental variables, which are only available at a number of environmental monitoring stations. This combination leads to a mixed environmental index (MEQI), which is more complete and adequate in a socioeconomic context. From the point of view of the computation process, we use kriging to match the monitoring stations registers to the Census data. We follow an inverse process as usual, since it leads to better estimates. In a first step, we krige the environmental variables to the complete surface and finally, we elaborate the environmental index. At last, in order to build the final synthetic index, we do not use Principal Components Analysis -as it is usual in this kind of exercises- but a better one, the Pena Distance method (DP2).

Aportaciones de los métodos Geo-cuantitativos a la estimación de precios de vivienda
(2008) Fernández-Avilés Calderón, Gema; Larraz Iribas, Beatriz
Housing Prices Statistic in Spain is quarterly published with several consequences for the economic agents involved in the sector, including particular citizens. Housing mean prices officially elaborated are of dubious usefulness for those interested in the sell and purchase of a particular house. They also suffer from other drawbacks: they do not take into account the geographical location of each of the houses they deal with. As a consequence, this paper suggests some techniques coming from geostatistics and geoeconometrics as an alternative to the official statistics. These methods, which have the space as their main element, can be used for estimating the mean housing price of Spain as well as for estimating the price of a particular house.

Building a spatio-temporal Environmental Quality Index: the case of Madrid
(Elsevier, 2010) Chasco Yrigoyen, Coro; Larraz Iribas, Beatriz; Montero Lorenzo, José María
The elaboration of Environmental Quality Indexes (EQI) for metropolitan areas isone of the main topics in environmental economics. This article introduces somemethodological and practical novelties building an EQI in Madrid (Spain). Managing with general air quality information, from the point of view of the selection of the variables, we consider noise ? joint to air pollution ? as a relevant environmental variable. Because the group of environmental variables is only available at a number of environmental monitoring stations, from the point of view of the computation process, we use kriging to match themonitoring stations registers to the Census data in order to map the EQI. In a first step, we krige the environmental variables to the complete surface and finally, we elaborate the environmental index. We follow an inverse process as usual in the literature, since it leads to better estimates. At last, in order to build the final synthetic index, we use the Pena Distance method. We compare EQI results computed in 2001 and 2008 considering the evolution in terms of air pollution and noise individually and as a whole.
