U.S. Regional Economic Fragmentation & Integration: Selected Empirical Evidence And Implications, Edward J. Feser, Geoffrey Hewings
Edward J Feser
The emergence of ten U.S. megaregions—increasingly contiguous spaces of high density development and population capturing a high share of U.S. economic activity—raises the question of appropriate scales for local, state and federal policy and how regional planning as a practice can adapt to an extended and, in some cases, almost continuous economic integration over space (RPA, 2006). Notions of cities as functional economic areas, more or less distinct spaces that operate as independent economic units, are less and less tenable as the basis for planning and policy making. At the same time, the megaregion phenomenon does not necessarily imply that …

The results show that Ellison and Glaeser’s theoretical finding that their concentration measures are robust to differences in the level of spatial aggregation in the underlying employment data does not generally hold in practice. This implies that sensitivity testing for alternative spatial units should accompany any analysis with the concentration measures.
