The spatial extent of localized agglomeration economies constitutes one of the central current questions in regional science. It is crucial for understanding firm location decisions and for assessing the influence of proximity in shaping spatial patterns of economic activity, yet clear-cut answers are difficult to come by. Theoretical work often fails to define or specify the spatial dimension of agglomeration phenomena. Existing empirical evidence is far from consistent. Most sources of data on economic performance do not supply micro-level information containing usable geographic locations. This paper provides evidence of the distances across which distinct sources of agglomeration economies generate benefits …

We investigate whether a more concentrated regional industrial structure – the dominance of a few large firms in a given industry in a region – limits agglomeration economies and ultimately diminishes the economic performance of firms in that industry, especially small ones. In an application to three industries using establishment-level production functions and a combination of confidential and publicly available data sources, we find a consistently negative and substantial direct productivity effect associated with regional industrial structure concentration and only mixed and relatively weak evidence that agglomeration economies are a mediating factor in that effect.

Industrial concentration and market power have been studied extensively at the national scale, in fields ranging from economics and industrial organization to regional science and economic development. At the regional scale, however, industrial structure and firm size relationships have received little attention outside of non-generalizable case studies, primarily because accurate measurements require difficult-to-obtain plant- or firm-level information. Readily available secondary data sources on establishment size distributions (such as County Business Patterns or the Census of Manufactures) cannot be linked to performance information for particular establishments or firms. Yet region-specific industrial structure may be a crucial determinant of firm performance and …
