Zusammenfassung:
Two fundamental issues have been ignored in the convergence debate which are addressed in this paper. First, there has been little attention paid to the development of a general model able to explain convergence a divergence. Second, in the rush to put data to a convergence hypothesis, researchers have failed to consider certain methodological procedures with respect to the treatment of capital. To remedy this problem we use an input-output approach to measure catch-up. To address the theoretical lacunae we present case studies of Portugal and Japan, two countries which by 1959 had attained the threshold level of development required to join the convergence- club , but which, for various historical (path-dependent) reasons, have diverged rapidly from each other in the period since the late 1950 s.
