Sigma-Convergence revisited

摘要: Referring to the diachronic decrease of overall dispersion a (regional) dataset, s-convergence is dominant concept in empirical regional convergence / divergence litera-ture. The paper revisits concept, expressing the, “classical”, coefficient variation and weighted formulas against backdrop median. To this end, specifies proposes pair of, “alternative”, for apprehend-ing concept. Such an endeavor stems from purely, statistical rationale that mean central tendency measure highly sensitive eventual presence outliers. theory-driven propositions are supported illustrative em-pirical analysis inequalities France, at NUTS III spatial level, period 2001-2015. findings provide valuable insight both theory policy-making, indicating different expressions may lead dif-ferent inferences with respect inequalities.
