    We analyze input-output matrices for a wide set of countries as weighted directed networks. These graphs contain only 47 nodes, but they are almost fully connected and many have nodes with strong self-loops. We apply two measures: random walk centrality and one based on count-betweenness. Our findings are intuitive. For example, in Luxembourg the most central sector is "Finance and Insurance" and the analog in Germany is "Wholesale and Retail Trade" or "Motor Vehicles", according to the measure. Rankings of sectoral centrality vary by country. Some sectors are often highly central, while others never are. Hierarchical clustering reveals geographical proximity and similar development status.

    Theorien der Regionalforschung sagen voraus, dass Betriebe von ihrer gegenseitigen räumlichen Nähe profitieren, wenn sie in einer Lieferbeziehung stehen, einen gemeinsamen Arbeitsmarkt haben, oder es zur Übertragung von Wissen kommt (die drei Marshall'schen Kräfte). Während die Existenz dieser externen Effekte als Ganzes durch die empirische Literatur gestützt wird, gibt es nur wenige Studien, welche zwischen den einzelnen Erklärungen unterscheiden. Diese Arbeit stellt einen neuen Ansatz vor, um die Bedeutung und die Größenordnung der einzelnen Marschall'schen Kräfte zu beurteilen. Anstatt externe Skalenerträge innerhalb einzelner Wirtschaftszweige zu messen, werden Beziehungen zwischen verschiedenen Branchen am gleichen Ort modelliert. In einer empirischen Untersuchung werden Wechselwirkungen in der Beschäftigungsentwicklung von 55 Wirtschaftszweigen in den Arbeitsmarktregionen der fünf größten Städte Westdeutschlands im Zeitraum von 1989 bis 2006 gemessen. Dazu werden Methoden der räumlichen Ökonometrie angepasst, wobei in diesem Kontext die Stärke der Wechselwirkungen durch die ökonomische anstelle der geographischen Nähe bestimmt wird. Die Ergebnisse deuten darauf hin, dass jede der drei Marschall'schen Kräfte dazu beitragen kann, Agglomerationsvorteile zu erklären. -- Urban Economics ; Interindustry Spillovers ; MAR-Externalities ; Spatial Econometrics Theories in regional science predict that related establishments benefit from their mutual proximity due to forward-backward linkages, labor market pooling and knowledge spillovers (the Marshallian forces). While the existence of these externalities as a whole is well supported by the empirical literature, there are few studies that discriminate between separate explanations. This paper introduces a new approach to assess the importance and magnitude of each of the Marshallian forces separately. Instead of measuring external economies of scale that take place within single industries, it models spillovers that happen between co-located industries. To this end, methods of spatial econometrics are adopted to measure interindustry relationships in employment growth between 55 industries of the manufacturing and service sectors in the labor market regions of the five largest cities in western Germany in the years 1989 to 2006. In this context, the strength of these relations is determined by economic closeness rather than by geography. The results suggest that each of the three Marshallian forces help to explain agglomeration externalities.

    The measurement of inter-connectedness in an economy using inputoutput tables is not new, however much of the previous literature has not had any explicit dynamic dimension. Studies have tried to estimate the degree of inter-relatedness for an economy at a given point in time using one inputoutput table, some have compared different economies at a point in time but few have looked at the question of how inter-connectedness within an economy changes over time. The publication in 2009 of a consistent series of inputoutput tables for Scotland offers the researcher the opportunity to track changes in the degree of inter-connectedness over the seven year period 1998 to 2004. The paper is in two parts. A simple measure of inter-connectedness is introduced in the first part of the paper and applied to the Scottish tables. It is shown that although the aggregate results might appear to indicate a degree of import substitution was taking place this result is not robust to industrial disaggregation. In the second part of the paper an extraction method is applied to an eleven sector disaggregation of the Scottish economy in order to estimate how interconnectedness has changed over time for each industrial sector. It is shown that for the majority of sectors the degree of interconnectedness with the rest of the Scottish economy has grown for others, in particular Financial Services and Energy and Water Supply it has not. -- Extraction method ; Input-Output Analysis ; Inter-connectedness ; Scottish economy
