Inversión en infraestructuras, crecimiento y convergencia regional

This paper presents estimates of the contribution of infrastructure investment to the growth of output and employment in Spain and its regions and investigates the impact of this factor on the process of regional convergence in income per capita during the period 1965-2004.

Immigration and Firm Growth: Evidence from Spanish cities

This article analyses the effect of immigration flows on the growth and efficiency of manufacturing firms in Spanish cities. To date, most studies have tended to focus on the effect immigrants have on labour markets at an aggregate level. Here, however, we undertake an exhaustive analysis at the firm level and report conclusive empirical findings. Ten years ago, Spain began to register massive immigration flows, concentrated above all on its most dynamic and advanced regions. Here, therefore, rather than focusing on the impact this has had on Spain’s labour market (changes to the skill structure of the workforce, increase in labour supply, the displacement of native workers, etc.), we examine the arrival of immigrants in terms of the changes this has meant to the structure of the country’s cities and their amenities. Thus, we argue that the impact of immigration on firm performance should not only be considered in terms of the labour market, but also in terms of how a city’s amenities can affect the performance of firms. Employing a panel data methodology, we show that the increasing pressure brought to bear by immigrants has a positive effect on the evolution of labour productivity and wages and a negative effect on the job evolution of these manufacturing firms. In addition, both small and new firms are more sensitive to the pressures of such immigrant inflows, while foreign market oriented firms report higher productivity levels and a less marked impact of immigration than their counterparts. In this paper, we also present a set of instruments to correct the endogeneity bias, which confirms the effect of local immigration flows on the performance of manufacturing firms.

Deconstructing Shocks and Persistence in OECD Real Exchange Rates

This paper analyzes the persistence of shocks that affect the real exchange rates for a panel of seventeen OECD developed countries during the post-Bretton Woods era. The adoption of a panel data framework allows us to distinguish two different sources of shocks, i.e. the idiosyncratic and the common shocks, each of which may have di¤erent persistence patterns on the real exchange rates. We first investigate the stochastic properties of the panel data set using panel stationarity tests that simultaneously consider both the presence of cross-section dependence and multiple structural breaks that have not received much attention in previous persistence analyses. Empirical results indicate that real exchange rates are non-stationary when the analysis does not account for structural breaks, although this conclusion is reversed when they are modeled. Consequently, misspecification errors due to the non-consideration of structural breaks leads to upward biased shocks' persistence measures. The persistence measures for the idiosyncratic and common shocks have been estimated in this paper always turn out to be less than one year.

Privatization and competition in the delivery of local services: An empirical examination of the dual market hypothesis

This paper empirically analyses the hypothesis of the existence of a dual market for contracts in local services. Large firms that operate on a national basis control the contracts for delivery in the most populated and/or urban municipalities, whereas small firms that operate at a local level have the contracts in the least populated and/or rural municipalities. The dual market implies the high concentration and dominance of major firms in large municipalities, and local monopolies in the smaller ones. This market structure is harmful to competition for the market as the effective number of competitors is low across all municipalities. Thus, it damages the likelihood of obtaining cost savings from privatization.

Economic effects of road accessibility in the Pyrenees: user perspective

At present, Spain faces one of the key moments in planning the future design of the infrastructure network. As a consequence of the critical role played by haulage in intra-European trade, the most important investments are those that guarantee that road haulage traffic can move freely at the borders. That is why it is necessary to make serious evaluations of the economic and social profitability of these investments. Normally the most significant social benefit of investment projects in transport infrastructure is time saving, which in turn changes traffic intensity. In this article we analyse the changes in the user excess caused by public investment in transport infrastructure planned by the Spanish government and which will be located on the border between Spain and France. In particular, we study the increase in network user surplus for HGV traffic in the Spanish and French border zones in the Pyrenees.

Impacto de la immigración sobre la esperanza de vida en salud y en discapacidad de la población española

La composición de la población española ha cambiado en los últimos años debido a la llegada de la población inmigrante. En este trabajo se acota cuánto podría llegar a cambiar la esperanza de vida en salud y en discapacidad de la población española, debido a la incorporación de un nuevo colectivo. La metodología propuesta permite calcular el máximo cambio posible en la esperanza de vida en salud y en discapacidad, en función de un porcentaje fijo de inmigración, y con el supuesto de mantenimiento de la mortalidad. Los resultados permiten analizar cambios en los costes de la dependencia para los mayores de 65 años.

Innovation, R&D spillovers and productivity: the role of knowledge-intensive services

This paper analyses the performance of companies’ R&D and innovation and the effects of intra- and inter-industry R&D spillover on firms’ productivity in Catalonia. The paper deals simultaneously with the performance of manufacturing and service firms, with the aim of highlighting the growing role of knowledge-intensive services in promoting innovation and productivity gains. We find that intra-industry R&D spillovers have an important effect on the productivity level of manufacturing firms, and the inter-industrial R&D spillovers related to computer and software services also play an important role, especially in high-tech manufacturing industries. The main conclusion is that the traditional classification of manufactured goods and services no longer makes sense in the ‘knowledge economy’ and in Catalonia the regional policy makers will have to design policies that favour inter-industrial R&D flows, especially from high-tech services.

Decomposing differences in total factor productivity across firm size

This paper investigates the extent to which the gap in total factor productivity between small and large firms is due to differences in the endowment of factors determining productivity and to the returns associated with these factors. We place particular emphasis on the contribution of differences in the propensity to innovate and in the use of skilled labor across firms of different size. Empirical evidence from a representative sample of Spanish manufacturing firms corroborates that both differences in endowments and returns to innovation and skilled labor significantly contribute to the productivity gap between small and large firms. In addition, it is observed that the contribution of innovation to this gap is caused only by differences in quantity, while differences in returns have no effect; in the case of human capital, however, most of the effect can be attributed to increasing differences in returns between small and large firms.

New evidence of the real interest rate parity for OECD countries using panel unit root tests with breaks

This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence of multiple structural breaks. Our results strongly support the fulfillment of the weak version of the RIRP for the studied period once dependence and structural breaks are accounted for.

Economía urbana y calidad de vida. Una revisión del estado del conocimiento en España

Quality of life is increasingly becoming a concept researched empirically and theoretically in the field of economics. In urban economics in particular, this increasing interest stems mainly from the fact that quality of life affects urban competitiveness and urban growth: research shows that when households and businesses decide where to locate, quality of life considerations can play a very important role. The purpose of the present paper is to examine the way economic literature and urban economic literature in particular, have adopted quality of life considerations in the economic thinking. Moreover, it presents the ways various studies have attempted to capture the multidimensional nature of the concept, and quantify it for the purposes of empirical research. Additionally we focus on the state of the art in Spain. Looking at the experiences in the last years we see very important possibilities of developing new studies in the field.

Capital humano: un análisis comparativo Catalunya-España

En este documento se analizan comparativamente algunos aspectos relativos al capital humano de la economía catalana y española. En primer lugar se compara la dotación de capital humano tanto desde una metodología más tradicional, como es el caso de años de educación, como desde el punto de vista de la valoración del activo mediante actualización de flujos salariales a lo largo del ciclo vital de los individuos. Los resultados muestran indicios de una cierta desaceleración en el crecimiento del stock de capital humano. Adicionalmente, se lleva a cabo una estimación de la existencia de externalidades de capital humano intra-establecimiento, con datos de la Encuesta de Estructura Salarial, desarrollando una metodología menos restrictiva que la tradicional. Los resultados muestran comportamientos similares de la economía española y catalana, apuntando a la existencia de externalidades.

L'estraperlo a Artesa de Segre: la lluita per la supervivència: el pa de cada dia

Treball de recerca realitzat per una alumna d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. L’estraperlo es pot definir com el comerç il•legal que es va dur a terme durant la postguerra espanyola i que consistia a comprar o intercanviar productes a baix preu a un lloc i vendre’ls o aconseguir-ne d’altres en un indret on es cotitzaven millor. Aquests productes eren articles intervinguts per l’estat o subjectes a racionament (1936-1952) i va passar a ser el mitjà de subsistència per a la majoria de persones que el van practicar. S’ha desenvolupat una aproximació a l’estraperlo a Artesa de Segre des de tres perspectives. La recollida de bibliografía ha permès situar-la dins l’ampli món de la postguerra espanyola. En el treball de camp, els testimonis ofereixen diferents punts de vista sobre les vivències de l’estraperlo i posteriorment s’analitzen els principals aspectes convergents i divergents a través d’un estudi comparatiu. Tota aquesta informació s’ha organitzat i presentat també en format audiovisual: el testimoni de l’estraperlista és narrat amb la seva pròpia veu. Les conclusions que s’en deriven són: l’estraperlo sorgí com a solució a la manca d’aliments i no és assimilable a el contraban; les circumstàncies precàries, les mancances de la postguerra i la disciplina arbitrària imposada pel mateix govern obligaren a la seva pràctica.

Estudi neurofisiològic del control executiu de l'atenció en l'esquizofrènia

Report for the scientific sojourn carried out at the Departament de Psicologia de la Universitat de les Illes Balears, Spain, from May until July 2006. Abnormalities in executive functions, including set shifting ability, represent a cardinal feature in schizophrenia. This ability to adapt behavior to changing environmental events or contingencies requires a mechanism for switching attention between learned stimulus-response associations, or task-sets. This project aimed at gaining further knowledge on the brain mechanisms related to the executive control of attention in schizophrenia during the performace of a task switching paradigm. Furthermore, a secondary goal was to further examine the interrelationships between endogenous and exogenous control processes in task set switching.
