Abstract:
In this paper we develop a coherent framework that integrates both traditional measures of â-convergence and ó-convergence within a study of cross-country income dynamics. To do this we exploit the close links that exist between studies of income mobility and studies analysing the progressivity of the tax system. We also develop a welfare interpretation for the concept of â-convergence, which distinguishes it from the more general form of ó-convergence and which also suggests that the â-process may be worthy of independent study. We illustrate our approach using data for the period 1960-2000.
