We use U.S. county data (3,058 observations) and 41 conditioning variables to study growth and convergence. Using OLS … and 3SLS-IV we report on the full sample and metro, non-metro, and 5 regional samples: (1) OLS yields convergence rates … around 2 percent; 3SLS yields 6-8 percent; (2) convergence rates vary (e.g., the Southern rate is 2.5 times the Northeastern …

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

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 …
