Geographies of Scope

Sunday, January 23rd, 2011

That’s the title of my new article with Kevin Stolarick and Charlotta Mellander just out in the Journal of Economic Geography.

Here’s the abstract:

The geographic clustering of economic activity has long been understood in terms of economies of scale across space. This paper introduces the construct of geographies of scope, which we argue is driven by substantial, large-scale geographic concentrations of related skills, inputs and capabilities. We examine this through an empirical analysis of the entertainment industry across U.S. metropolitan areas from 1970 to 2000. Our findings indicate that geographies of scope (or collocation among key related entertainment subsectors and inputs) explain much of the economic geography of entertainment even when scale is controlled for, though our regressions over time suggest the role of scope is decreasing. Furthermore, we find that the entertainment sector as a whole and its key subsectors are significantly concentrated in two superstar cities—New York and Los Angeles—far beyond what their population size (or scale effects) can account for, while the pattern falls off dramatically for other large regions.

Where All the Smart People Are Going

Wednesday, December 22nd, 2010

Smart people of the highly educated sort that economists refer to as “human capital” are key engines of economic growth and development. More and more, they have been clustering in a relative handful of big cities. A recent post by Aaron M. Renn, who blogs as The Urbanophile, charts the changing density of college educated people across U.S. metro areas. His analysis builds on an earlier analysis by Rob Pitingolo (I blogged about it here) which introduced a measure of human capital density.
