An Empirical Analysis of Convergence Hypothesis
A useful contribution of wide ranging debate in the growth literature is that it has put forward a number of testable hypotheses. One of such hypotheses is known as the convergence hypothesis whereby it is postulated that in the long run developing countries would catch-up with the developed countries in terms of per capita income. Although the convergence hypothesis has gained researchers’ interest in recent times, the basic proposition was laid down in the neo-classical growth model of Solow (1956) and Swan (1956). Traditionally Solow-Swan model has been regarded as a theoretically consistent answer to Harrods’s (1939) twin problems of discrepancy between the warranted and natural rates of growth and instability in the growth process. Although Solow- Swan model is designed to study growth process within a single country, the concept of conditional convergence is far from being alien to the model; it in fact forms the core of argument in the attack on Harrod-Domar model [Harrod (1939) and Domar (1946)].
