‘Williamson’s Fallacy’ in Estimation of Inter-Regional Inequality

Author

  • Gluschenko, Konstantin

Abstract

While estimating regional inequality, many economists use inequality indices weighted by regions’ shares in the national population. Despite this approach is widespread, its adequacy has not received attention in the regional science literature. This paper proves that such approach is conceptually inconsistent, yielding an estimate of interpersonal inequality among the whole population of the country rather than an estimate of regional inequality. Moreover, the population-weighted inequality indices do not meet requirements to an adequate inequality measure.
