Interregional Per Capita Income Differentials and Convergence: 1880–1950
Published online by Cambridge University Press: 11 May 2010
Abstract
In several recently published works Richard A. Easterlin has shown that per capita incomes as measured in current dollars have tended to converge over time. In this paper the per capita income estimates have been adjusted for interregional differences in prices. In adjusting the regional per capita income estimates for interregional differences in both urban and rural-urban prices it was found that no significant differences occurred in either the levels of differences or in the rates of convergence from the original estimates. In addition, no significant correlation was found between interregional per capita incomes and price levels.
