The economic performance of regions

This paper examines the basic facts about the regional economic performance, the composition of regional economies and the role of clusters in the US economy over period of 1990 to 2000. The performance of regional economies varies markedly in terms of wage, wage growth, employment growth and patenting rate. Based on the distribution of economic activity across geography, we classify US industries into traded, local and resource-dependent. Traded industries account for only about one-third of employment but register much higher wages, far higher rates of innovation and influence local wages. We delineate clusters of traded industries using co-location patterns across US regions. The mix of clusters differs markedly across regions. The performance of regional economies is strongly influenced by the strength of local clusters and the vitality and plurality of innovation. Regional wage differences are dominated by the relative performance of the region in the clusters in which it has positions, with the particular mix of clusters secondary. A series of regional policy implications emerge from the findings.
