Sigma-Convergence Versus Beta-Convergence: Evidence from U.S. County-Level Data

Abstract

In this paper we outline (i) why ó-convergence may not accompany â- convergence, (ii)cite evidence of â-convergence in the U.S., (iii) and use USA county-level data containing over 3,000 cross-sectional observations to demonstrate that ó-convergence does not hold across the U.S., or within the vast majority of the individual U.S. states.Economic Growth, Convergence, ó-convergence, sigma convergence, â-convergence, beta convergence, US County Level Data
