We investigate the growth enhancing variables in a group of countries belonging to the same geographical area namely, India, Sri Lanka, Pakistan and Bangladesh over the period 1960–2010. We find that this “homogeneity” does not necessarily imply that countries have the same growth enhancing variables due mainly to differences in institutions and policies. Our result suggests that time-series econometrics are preferable to identify the growth drivers for a country accurately.
