In undertaking an analysis of neighbouring effects on European regional patterns of specialization, this paper makes two main contributions to the literature. First, we use a spatial weight matrix that takes into consideration membership of an EU cross-border regional association. We then compare our results with those obtained using a contiguity matrix and constitute an upper bound for our parameter of interest. In a further stage, we divide the CBR associations on the basis of their longstanding and the intensity of their cooperation to determine whether the association type has a significant impact. Second, we examine the sensitivity of our results to the use of alternative relative specialization indices.

The purpose of this article is to offer a practical approach to the new European dimension for regional parliaments signified by the entry into force of the Treaty of Lisbon. The parliamentary scrutiny of subsidiarity by way of the early warning system has assigned a new mission to legislative assemblies with the aim of reinforcing the intervention of regions in the drafting of policies by Union institutions. In the Spanish case, the institutionalisation of this mechanism came about with Act nº 24/2009, which attributes to the Joint Committee for the European Union, in the name of the Cortes Generales [the Spanish Parliament], the function of receiving the proposals for legislative acts by the EU and transferring them to the regional parliaments in order for the latter to issue, in a brief period of four weeks, a report on compliance with the principle of subsidiarity. The majority of regional parliaments have also carried out normative reforms to regulate the procedure of participation in the early warning system.

In this paper we seek to verify the hypothesis that trust and cooperation between individuals, and between them and public institutions, can encourage technological innovation and the adoption of knowledge. Additionally, we test the extent to which the interaction of social capital with human capital and R&D expenditures improve their effect on a region’s ability to innovate. Our empirical evidence is taken from the Spanish regions and employs a knowledge production function and longitudinal count data models. Our results suggest that social capital correlates positively with innovation. Further, our analysis reveals a powerful interaction between human and social capital in the production of knowledge, whilst the complementarity with R&D efforts would seem less clear.

The first objective of this study is to furnish new evidence concerning the aggregate profitability of the accumulation of human capital. In addition to the traditional measure of the return to human capital, combining the information on its shadow price with the social cost of providing education allows us to confirm the profitability of human capital investments as a tool for promoting economic growth. The possibility of obtaining estimations of these effects for each Spanish region enables us to empirically evaluate the amount of heterogeneity across economies in the effects of human capital. As a second objective, we provide evidence on the indirect effect of human capital in making private capital investment more attractive. Among the main explanations for this process, we observe that higher worker skill levels enable higher returns to be extracted from investment in physical capital.

Recent theoretical developments on concession contracts for long term infrastructure projects under uncertain demand show the benefits of allowing for flexible term contracts rather than fixing a rigid term. This study presents a simulation to compare both alternatives by using real data from the oldest Spanish toll motorway. For this purpose, we analyze how well the flexible term would have performed instead of the fixed length actually established. Our results show a huge reduction of the term of concession that would have dramatically decreased the firm’s benefits and the user’s overpayment due to the internalization of an unexpected traffic increase.

The use of tolls is being widespread around the world. Its ability to fund infrastructure projects and to solve budget constraints have been the main rationale behind its renewed interest. However, less attention has been payed to the safety effects derived from this policy in a moment of increasing concern on road fatalities. Pricing best infrastructures shifts some drivers onto worse alternative roads usually not prepared to receive high traffic in comparable safety standards. In this paper we provide evidence of the existence of this perverse consequence by using an international European panel in a two way fixed effects estimation.

This paper provides novel empirical evidence of the indirect effect of educational attainment on regional economic growth, through its influence on the profitability of investment in physical capital. We test the hypothesis that the regional heterogeneity of the return to physical capital can be directly related to the existing heterogeneity in the educational attainment of workers. The results for the Spanish case support our hypothesis that the higher the educational attainment of workers the greater the returns on investment in physical capital. In fact, this effect seems to be sufficiently strong to have counterbalanced the traditional mechanism of decreasing returns to capital accumulation.

Este trabajo aporta evidencia empírica acerca de los factores determinantes de las diferencias en la probabilidad de acceder a un contrato indefinido entre las distintas regiones españolas. Para ello, y de forma novedosa en este contexto, se aplica una extensión de la metodología tradicional de Oaxaca-Blinder al caso de modelos no lineales. Los resultados apuntan a la coexistencia de distintas “culturas de la temporalidad” en España, al existir discrepancias regionales significativas en el empleo del trabajo temporal como medida de flexibilización laboral. Estas diferencias tienen incluso más capacidad explicativa que las discrepancias en las características de la mano de obra y de las empresas instaladas en cada región. Estos resultados cuestionan las medidas adoptadas para combatir el problema de la precariedad laboral en España, al no haber considerado las especificidades regionales.

The present study aimed at determining a regional geochemical reference for sediment samples from Lago Paranoá watershed through the formulation of geoaccumulation indexes. The need for obtaining information from areas representing low human impact was the basis of this work. Systematic evaluations of sediment from Lago Paranoá will bring valuable information regarding the potential risk that this layer represents for aquatic organisms. Thus, despite the recent water quality improvements achieved in this ecosystem, contaminants incorporated in the sediments may be remobilized for alterations in the adjacent environment. The adsorption capacity of chemical elements in sediment samples was controlled through the variation in the amounts of organic matter, the mineralogical composition and the granulometric variation. By creating the Sediment Enrichment Index (SEI) through the normalization of analytical data it was possible to establish the magnitude of this enrichment relatively to naturally occurring concentrations all over the region of interest. Normalized values with organic matter were especially useful for the evaluation of lothic systems.

This work presents a proposal for the management of residues from teaching laboratories. The main goals of the proposal are: scale reduction of experiments, reuse of residues as raw materials for new experiments and appropriate treatment and storage of residues. The methodology includes standardized labels for residue classification and registration of experimental classes and their residues in files. The management seemed to be efficient, resulting in a reduction of the amount of reagents utilized and residues generated, and an increase of reutilization of residues. A considerable decrease of needed storage space and suitable methods for correct residue disposal were achieved. We expect that all laboratories, including those exclusively for research activities, become involved, in a near future, in the Residue Management Project of URI - Campus Erechim.

In this paper we propose a latent variable model, in the spirit of Israilevich and Kuttner (1993), to measure regional manufacturing production. To test the validity of the proposed methodology, we have applied it for those Spanish regions that have a direct quantitative index. The results demonstrate the accuracy of the methodology proposed and show that it can overcome some of the difficulties of the indirect method applied by the INE, the Spanish National Institute of Statistics.

Este trabajo analiza cual ha sido la evolución de la investigación en ciencia regional y urbana en España en el período 1991-2000 situándola en el contexto internacional. Para ello, se elaboran rankings de países, autores e instituciones en función de las publicaciones realizadas en una muestra de nueve revistas internacionales ampliamente reconocidas dentro de este campo. Los resultados muestran que la mejora en la posición relativa a nivel internacional encontrada por otros autores para el conjunto de la investigación española en economía también se produce en el contexto de la investigación económica regional y urbana De hecho, hay un claro aumento de la presencia a nivel internacional de los autores e instituciones españolas motivado en buena medida por un incremento de las publicaciones de autores con tradición en la investigación en ciencia regional y urbana pero también por la irrupción con fuerza de 'nuevos' autores.

The ecological fallacy (EF) is a common problem regional scientists have to deal with when using aggregated data in their analyses. Although there is a wide number of studies considering different aspects of this problem, little attention has been paid to the potential negative effects of the EF in a time series context. Using Spanish regional unemployment data, this paper shows that EF effects are not only observed at the cross-section level, but also in a time series framework. The empirical evidence obtained shows that analytical regional configurations are the least susceptible to time effects relative to both normative and random regional configurations, while normative configurations are an improvement over random ones.
