Abstract

We investigate the income convergence hypothesis for 24 OECD countries using Fourier-type unit root tests that can account for structural breaks of unknown number, timing and functional form in a series’ data generating process. Our results indicate that all 24 countries have followed a nonlinear underlying growth path (relative to the US) over the post-war era. These growth paths indicate that as many as half of the countries sampled are systematically catching-up with the US. Only a handful show evidence of being in relative decline, but the fact that this group includes several G7 economies is of concern.
