In this paper we outline (i) why sigma-convergence may not accompany beta-convergence, (ii) discuss evidence of beta-convergence … sigma-convergence cannot be detected at the county-level across the U.S., or within the large majority of the individual U …

We use U.S. county-level data to estimate convergence rates for 22 individual states. We find significant heterogeneity …. E.g., the California estimate is 19.9 percent and the New York estimate is 3.3 percent. Convergence rates are …

estimate heterogeneity in convergence rates across 22 individual U.S. states. Applying GMM estimation, we find significant … heterogeneity in the state-level convergence rates. For example, while the average convergence rate is 9.2 percent, the California … estimate is 19.9 percent and the New York estimate is 3.3 percent. The estimated convergence rates are essentially uncorrelated …

convergence of GDP per worker observed across the European regions, in the absence of data on regional TFP. Second, the spatial … regional convergence in Europe. As for the first issue, our aim is to assess whether the convergence observed across European … regions is due to convergence in technology as well as to convergence in capital-labour ratios. We first develop a growth …
