Diversity, stability and regional growth in the U.S. (1975-2002)

This paper summarizes the theoretical arguments from evolutionary theory and ecological economics to put the trade-off between regional economic diversity and regional economic growth on stronger theoretical foundations. Hypotheses are tested using an empirical model that links regional economic diversity to stability and growth using data on 177 BEA areas of the continental United States during the period (1975-2002).evolutionary economics, ecological economies, diversity, stbility, regional growth

Relatedness, Industrial Branching and Technological Cohesion in US Metropolitan Areas

Relatedness, industrial branching and technological cohesion in US metropolitan areas, Regional Studies. Work by evolutionary economic geographers on the role of industry relatedness for regional economic development is extended into a number of methodological and empirical directions. First, relatedness is measured as the intensity of inputoutput linkages between industries. Second, this measure is employed to examine industry evolution in 360 US metropolitan areas. Third, an employment-weighted measure of metropolitan technological cohesion is developed. The results confirm that technological relatedness is positively related to metropolitan industry portfolio membership and industry entry and negatively related to industry exit. The decomposition of technological cohesion indicates that the selection of related incumbent industries complements industry entry and exit as the main drivers of change in metropolitan technological cohesion

Exploring Evolutionary Economic Geographies

Evolutionary approaches in economics have gathered increasing support over the last 25 years. Despite an impressive body of literature, economists are still far from formulating a coherent research paradigm. The multitude of approaches in evolutionary economics poses problems for the development of an evolutionary economic geography. For the most part, evolutionary economic geography imports selective concepts from evolutionary biology and economics and applies those concepts to specific problems within economic geography. We discuss a number of problems with this approach and suggest that a more powerful and appealing alternative requires the development of theoretically consistent models of evolutionary processes. This paper outlines the contours of an evolutionary model of economic dynamics where economic agents are located in different geographical spaces. We seek to show how competition between those agents, based on the core evolutionary principles of variety, selection and retention, may produce distinct economic regions sharing properties that differentiate them from competitors elsewhere. These arguments are extended to illustrate how the emergent properties of economic agents and places co-evolve and lead to different trajectories of economic development over space.evolutionary economics, economic geography, Generalized Darwinism, biological metaphors, self-organization

Telephone Communication Patterns in Austria. A Comparison of the IPFP based Graph-Theoretic and the lntramax Approaches

Two alternative methodological approaches (the IPFP based and the intramax procedures) to the problem of pattern identification in spatial interaction data are compared and evaluated in this paper. After a general discussion of the major characteristics and shortcomings of these methodologies, the paper presents the findings of a case study relying on telecommunication data measured by the Austrian PTT in 1991, in terms of erlangs. The results clearly illustrate the superiority of the intramax approach in the context of mediumsized and relatively centralised flow systems.

Evolutionary Economic Geography, Institutions, and Political Economy

In this response to MacKinnon et al. (2009 ), I argue that the theoretical development of evolutionary economic geographies is necessary in order to evaluate its unique contribution to an understanding of the uneven development of the space economy; that the distinction between evolutionary and institutional economic geographies is overdrawn; that the neglect of class, power, and the state reflect empirical rather than theoretical shortcomings of the evolutionary approach; and that there is significant potential overlap between evolutionary and political economy approaches.
