TETING SIGMA CONVERGENCE ACROSS NEW EU MEMBERS [PDF]

Revista Economica, 2013
Even though the issue of convergence between the member states of European Union is an extremely debated subject nowadays, the existing disparities continue to persist and even accentuate. Furthermore the economists and researchers in the field are interested to analyze whether the rich economies will continue to develop and at what speed on one side ...

On infinite matrices and lacunary σ-convergence

Applied Mathematics and Computation, 2011
A lacunary sequence is an increasing sequence \(\theta = (k_r)\) of non-negative integers where \(k_0=0\) with \(k_r-k_{r-1} \to \infty\) as \(r\to \infty\). Let \(\sigma\) be a one-to-one mapping from the set of natural numbers into itself. A continuous linear functional \(\phi\) on \(\ell _{\infty}\) is said to be an invariant mean or a \(\sigma ...

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.

The wedge and sigma convergence among U.S. states

Atlantic Economic Journal, 1996
The paper attempts to empirically quantify the factors underlying sigma convergence among the contiguous states of the U.S. Using annual state data the study finds a significant effect of the wedge in explaining the variation in state per capita productivity.
