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 US metropolitan areas from 1970 to
2000.
