ABSTRACT This paper examines the micro-foundations of occupational agglomeration in U.S. metropolitan areas, with an emphasis on labor market pooling. Controlling for a wide range of occupational attributes, including proxies for the use of specialized machinery and for the importance of knowledge spillovers, we find that jobs characterized by a unique knowledge base exhibit higher levels of geographic concentration than do occupations with generic knowledge requirements. Further, by analyzing co-agglomeration patterns, we find that occupations with similar knowledge requirements tend to co-agglomerate. Both results provide new evidence on the importance of labor market pooling as a determinant of occupational agglomeration.

    ABSTRACT: Knowledge spillovers have been considered a major driver for the increased rate of innovation in technological clusters. In this study, we respond to some recent calls for a deeper understanding of the mechanisms of localized knowledge exchange, by focusing on the effect of local sources of knowledge on inventors in telecommunication clusters. We differentiate between the different types of knowledge in our model for knowledge accessibility, and present a framework for knowledge exchange within clusters. We empirically test this model on inventors across the USA, where we compare the responses of inventors in clusters to inventors who are not in clusters. The results highlight the significance of the ‘local buzz’, and the dynamics of knowledge spillovers are explored.

    ABSTRACT: This paper discusses the prevalence of Silicon Valley-style localizations of individual manufacturing industries in the United States. A model in which localized industry-specific spillovers, natural advantages, and random chance contribute to geographic concentration motivates new indices of geographic concentration and coagglomeration. The indices contain controls that facilitate cross-industry and cross-country comparisons. The authors find almost all industries to be more concentrated than a random dart-throwing model predicts but the degree of localization is often slight. They also discuss which industries are concentrated, the geographic scope of localization, coagglomeration patterns, and other topics. Copyright 1997 by the University of Chicago.

    ABSTRACT: This paper presents evidence on the long-run trends in U.S. regional specialization and localization and examines which model of regional specialization is most consistent with the data. Regional specialization in the United States rose substantially between 1860 and the turn of the twentieth century, flattened out during the interwar years, and then fell substantially and continuously since the 1930s. The analysis of the long-run trends in U.S. regional specialization and localization supports explanations based on production scale economies and the Heckscher-Ohlin model but is inconsistent with explanations based on external economies.
