INTRA-REGIONAL EMPLOYMENT GROWTH IN LUXEMBOURG (1994,2005)

GEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 1 2010

ABSTRACT. The specialization of city-centres towards more advanced service activities has mostly been studied in the largest city-regions, the case of smaller urban centres being less well documented. In that context, the objective of this article is to analyse the role of sectoral and regional factors in employment growth in Luxembourg between 1994 and 2005. Using statistical data from the Luxembourg General Inspection of Social Security, this contribution distinguishes 12 categories of manufacturing industries and services according to an OECD-Eurostat knowledge-based classification. Five intra-regional areas are distinguished based on morphological and functional criteria in the Luxembourg Metropolitan Area. Using several indexes, this article first analyses the sectoral specialization and geographical concentration of employment. A model of intra-regional employment growth, initially developed by Marimon and Zilibotti and applied at the European level, is then shown to account for 40 per cent of employment growth. An estimation of the contributions of sectoral and geographical factors highlights the primacy of the latter over the former. Finally, the construction of virtual economies confirms the City's overall lower performance as compared to its close periphery. Results underscore a process of functional integration in the Luxembourg metropolitan area: as the core of the city undergoes a specialization process, the urban area benefits from a relocation of activities less sensitive to distance and transaction costs, while the periphery becomes increasingly diversified, notably in the South where traditional industrial activities are being replaced by service activities. These results suggest that the evolution pattern of employment growth in Luxembourg is very similar to that of some larger metropolitan centres, owing to its exceptional financial service activities.

A commentary on coastal research in New Zealand universities

NEW ZEALAND GEOGRAPHER, Issue 2 2008
Paul S. Kench
Abstract: , University research in coastal geomorphology, processes and management has made a major contribution to the fundamental understanding of coastal systems in New Zealand over the past 43 years. This article examines the growth in university-based coastal research since 1964 and discusses the geographical pattern and themes of this research. Data indicate a significant geographical concentration of research effort and focus on a narrow range of research themes. Underlying reasons for these characteristics of New Zealand coastal research are explored and challenges facing university based research are discussed. Such challenges can be overcome through a more coordinated research effort to realize the huge potential to undertake coastal science of national relevance and international significance. [source]


Modelling the geography of economic activities on a continuous space,

PAPERS IN REGIONAL SCIENCE, Issue 4 2001

Birth-death processes; economic geography; geographical concentration; Markov fields; regional economic growth Abstract In the present article we propose a spatial micro econometric approach for studying the geographical concentration of economic activities. We analyse the incentives to use this approach rather than the traditional one based on regional aggregates. As an example, we present our prototypical theoretic model , to be seen as a continuous space version of Krugman's concentration model , that includes birth, survival and growth components. We present a numerical estimation of the birth model for a set of data referring to the concentration of the manufacturing industries in the San Marino Republic. [source]


U.S. Hog Production and the Influence of State Water Quality Regulation

CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2001
Mark Metcalfe
The U.S. hog industry is experiencing an increase in both the average size and in the geographical concentration of feeding operations. These increases have caused public attention to focus on the environmental consequences of hog production and on the regulations imposed to limit these consequences. This study examines the influence of state water quality regulatory stringency on hog production in the United States. The results of this analysis provide evidence that environmental compliance costs are significant for small hog feeding operations, while production on large operations does not appear to be influenced by the level of state environmental regulatory stringency. On assiste présentement à une augmentation de la taille des exploitations et à une concentration géographique des établissements d'engraissement dans le secteur américain de l'élevage porcin. Ces changements ont amené la population à s'intéresser aux répercussions de la production porcine sur l'environnement et aux réglements adoptés en vue d'atténuer de telles répercussions. L'auteur détermine de quelle maniére la sévérité des réglements d,État sur la qualité de l'eau influe sur l'élevage des pores aux États-Unis. Les résultats de son analyse prouvent que le respect des règlements sur la protection de l'environnement engendre des coûts appréciables pour les petits éleveurs, alors que les exploitations de plus grande envergure ne sont pas aussi affectées par la rigueur de la réglementation d'État en matiére d'environnement.
