Taxing capital flows: an empirical comparative analysis

Recent studies have analysed the impact of capital account opening on income growth, implicitly assuming that the various forms of foreign savings have similar effects. In fact, theoretical considerations suggest that the individual components of private capital inflows have different effects on growth. This paper analyses the link between income growth and private capital inflows. It presents system GMM estimates with annual observations from 1985 to 1996 for 72 countries. When full-sample results are checked for country and period changes, most of capital inflow series lose their ability to explain income growth. Bank flows stand as the sole source of foreign financing that displays a positive and robust correlation with growth.
