Beta and sigma convergence: A Mathematical Relation of Causality
2005This paper examines and compares in detail the concepts of β and σ-convergence. It provides a mathematical relation of causality between these two concepts, showing that a necessary condition for the existence of σ-convergence is the existence of β ...

Sigma Convergence Versus Beta Convergence: Evidence from County-level Data [PDF]
, 2003 This note outlines: 1) Why sigma-convergence may not accompany beta-convergence; 2) Cites evidence of beta-convergence in the U.S.; 3) Demonstrates that sigma-convergence does not hold across the U.S. or within most U.S. states; and 4) Demonstrates the robustness of this finding to increases in mean income.
