A note on Spatial Autocorrelation at a Local Level

In this paper we analyze the existence of spatial autocorrelation at a local level in Catalonia using variables such as urbanisation economies, population density, human capital and firm entries. From a static approach, our results show that spatial autocorrelation is weak and diminishes as the distance between municipalities increases. From a dynamic approach, however, spatial autocorrelation increased over the period we analysed. These results are important from a policy point of view, since it is essential to know how economic activities are spatially concentrated or disseminated. Key words: spatial autocorrelation, municipalities. JEL classification: R110, R120

Spillovers and growth in a local interaction model

In this paper we aim at studying to what extent spillovers between firms may foster economic growth. The attention is addressed to the spillovers connected with the R&D activity that improves the quality of the goods firms supply. Our model develops a growth theory framework and we assume that firms spread around a circle. Our study assesses that spillovers between neighbors affect the probability of successful research for each of them. In particular, spillovers are the forces fuelling growth when, on the whole, firms turn out to be net receivers with respect to their neighbors.

Sources of Competitiveness in Tourist Local Systems

At the end of the XIX Century, Marshall described the existence of some concentrations of small and medium enterprises specialised in a specific production activity in certain districts of some industrial English cities. Starting from his contribute, Italian scholars have paid particular attention to this local system of production coined by Marshall under the term industrial district. In other countries, different but related territorial models have played a central role as the milieu or the geographical industrial clusters. Recently, these models have been extended to non-industrial fields like culture, rural activities and tourism. In this text, we explore the extension of these territorial models to the study of tourist activities in Italy, using a framework that can be easily applied to other countries or regions. The paper is divided in five sections. In the first one, we propose a review of the territorial models applied to tourism industry. In the second part, we construct a tourist filiere and we apply a methodology for the identification of local systems through GIS tools. Thus, taxonomy of the Italian Tourist Local Systems is presented. In the third part, we discuss about the sources of competitiveness of these Tourist Local Systems. In the forth section, we test a spatial econometrics model regarding different kinds of Italian Tourist Local Systems (rural systems, arts cities, tourist districts) in order to measure external economies and territorial networks. Finally, conclusions and policy implications are exposed.

Industrial location at a local level: some comments about the territorial level of the analysis

This paper contributes to the existing literature on industrial location by discussing some issues regarding the territorial levels that have been used in location analysis. We analyse which could be the advantages and disadvantages of performing locational analysis at a different local levels. We use data for new manufacturing firms located at municipality, county and travel to work areas level. We show that location determinants vary according to the territorial level used in the analysis, so we conclude that the level at which we perform the investigation should be carefully selected. Keywords: industrial location, cities, agglomeration economies, count data models.

Análisis de la distribución de las emisiones de CO2 a nivel internacional mediante la adaptación del concepto y las medidas de polarización

La medida de la polarización está ligada a la inestabilidad potencial, la aparición de grupos con intereses opuestos, generada por una situación de distribución específica. Esta investigación analiza la distribución internacional de las emisiones de CO2 per cápita a través de la adaptación del concepto y las medidas de polarización. La descripción agrupada más interesante que se deriva del análisis de polarización es la de dos grupos. Estos grupos coinciden ampliamente con los países del Anexo B del Protocolo de Kyoto y los que no lo son, lo que podría indicar la capacidad del análisis de polarización para explicar la generación de grupos en el mundo real. El análisis muestra una reducción significativa en la polarización internacional de las emisiones de CO2 per cápita entre 1971 y 2001. Esto se explica en gran parte por el aumento en las emisiones experimentado por China e India. Una reducción en la polarización puede implicar una reducción en la dificultad de alcanzar acuerdos. No obstante, la polarización no ha cambiado mucho desde 1995 o 1997 (año en que tuvieron lugar las negociaciones de Kyoto), lo que podría indicar que la polarización de la distribución de emisiones entre países es aún uno de los factores importantes llevando a la dificultad en alcanzar nuevos acuerdos respecto a las políticas globales de.

Control de entrenamientos para deportistas de alto nivel: portal web

Aquesta memòria tracta sobre el desenvolupament d’una aplicació en un portal web, la qual ha de ser un suport per a que els entrenadors puguin controlar i analitzar els entrenaments de cada un dels seus esportistes, sense la necessitat de tenir que perdre molt de temps en la captació, transmissió i processament de la informació resultant de realitzar un entrenament. Aquesta aplicació neix amb la intenció de ser una eina útil tant per entrenadors, metges i esportistes, en l’obtenció dels objectius fixats.

Do creative industries cluster? mapping creative local production systems in Italy

An important debate on the role of creativity and culture as factors of local economic development is distinctly emerging. Despite the emphasis put on the theoretical definition of these concepts, it is necessary to strengthen comparative research for the identification and analysis of the kind of creativity embedded in the territory as well as its determinants. Creative local production systems are identified in Italy and Spain departing from local labour markets as territorial units, and focusing on two different kinds of creative

Codificación a nivel de paquete para comunicaciones móviles por satélite

Una de les opcions que es contemplen per transmetre continguts multimèdia i proporcionar accés a Internet a grups de usuaris mòbils és fer servir satèl·lits. Les condiciones de propagació del canal mòbil impliquen que d'una manera o altra haurem de garantir la qualitat de servei. Això té fins i tot més importància si tenim en compte que, en el cas d'accés a Internet, no es té la capacitat d'assumir cert percentatge de pèrdua de dades que tenim, per exemple, en la transmissió de so o vídeo (rebaixant la qualitat). Entre les principals alternatives per a aquesta classe d’entorns es troba la inclusió de codificacions a nivell de paquet. El funcionament d'aquesta tècnica es basa en incloure a la transmissió paquets redundants, obtinguts mitjançant un determinat algoritme. El receptor podrà recuperar la informació original que es volia enviar, sempre que hagi rebut una certa quantitat de paquets, similar a la quantitat de paquets originals. A aquest mecanisme se'l coneix com Forward Error Correction (FEC) a nivell de paquet. En aquesta memòria es valoren breument les alternatives existents i s'expliquen algunes de les codificacions per a FEC més importants. A continuació es realitza un estudi compartiu d’algunes d'elles: les variants de LDPC (Low Density Parity Check) conegudes com LDGM (Low Density Generator Matrix), i la codificació Raptor

Economic impact of a new museum on the local economy: "The Gaudí Centre"

In this paper we analyse the economic impact of a new museum (the Gaudí Centre) on the local economy of Reus, a city in the province of Tarragona (southern Catalonia). We use a Keynesian income multiplier model to evaluate the effects of this new cultural venue on local income. In our calculation of the economic impact we distinguish between two phases: the construction phase and the exploitation phase. Our results show the important income impact of this cultural investment on the local economy.

Contribució de les varietats locals a la conservació de l'agrobiodiversitat: cas d'estudi en horts d'alta muntanya al Pallars Jussà, Pirineu català

Durant les últimes dècades, el paper dels horts familiars en la conservació de la agrobiodiversitat ha adquirit cada vegada més importància a nivell mundial. Les varietats locals que es cultiven en aquests horts tenen propietats intrínseques que les fan superiors a les comercials en molts aspectes, com han demostrat alguns dels estudis sobre aquests agroecosistemes duts a terme als Tròpics, i que posen en evidència l'actual sistema agrícola, alhora que representen una oportunitat per al desenvolupament sostenible de l´agricultura. En aquest treball d'investigació, dut a terme a la Vall Fosca (Pirineus Català d'Espanya) s'ha estudiat el paper les varietats locals dels horts familiars com a mecanisme de millora i manteniment d'aquests agroecosistemes, analitzant quins són els possibles factors sociodemogràfics i ecològics que condicionen el desenvolupament d'aquestes varietats als horts familiars.

Does urban sprawl increase the costs of providing local public services? Evidence from Spanish municipalities

This paper examines the impact of urban sprawl, a phenomenon of particular interest in Spain, which is currently experiencing this process of rapid, low-density urban expansion. Many adverse consequences are attributed to urban sprawl (e.g., traffic congestion, air pollution and social segregation), though here we are concerned primarily with the rising costs of providing local public services. Our initial aim is to develop an accurate measure of urban sprawl so that we might empirically test its impact on municipal budgets. Then, we undertake an empirical analysis using a cross-sectional data set of 2,500 Spanish municipalities for the year 2003 and a piecewise linear function to account for the potentially nonlinear relationship between sprawl and local costs. The estimations derived from the expenditure equations for both aggregate and six disaggregated spending categories indicate that low-density development patterns lead to greater provision costs of local public services.
