Zusammenfassung (übersetzt):
This paper is a preliminary appraisal ofthe stylised facts and the major open questions - both methodological and Substantive - that have emerged in the empirical literature on international per-capita income and productivity convergence. On basis of various distinctivc lines of reasoning, it is argued that the evidence infavour ofthe convergence hypothesis that has been gained on basis of Barro-type regressions is (i) econometrically unconvincing due to major methodological fallacies and (ii) not really helpful for discriminating between neoclassical and endogenous growth models.
