The Evolution of Income Disparities across US Metropolitan Statistical Areas

The paper investigates how the spatial evolution of core-based city regions affects the dynamics of income disparities across Metropolitan Statistical Areas in the United States between 1971 and 2010. Treating initially non-metropolitan counties as part of the functional economic system for the whole time period changes the internal composition of average per capita personal income thus biasing convergence analysis. The paper analyses the dynamics of the cross-sectional distribution of per capita personal income by comparing different methods to define MSAs over time. The results show that a cluster of high income economies emerges when MSAs are allowed to evolve spatially
