Macroeconomic determinants of growth: new measurement and evidence on the effect of political freedom

Empirical results based on the re-examination of the data and models offered by Kormendi and Meguire (1985) and Gupta (1988) suggest that the impact of political freedom on economic growth is positive and significant. In particular, the replacement of their civil liberties variable by a new varible representing social capabilities improves the magnitude and significance of the estimated parameters and explanatory power of the regressions. The marginal contribution of social capabilities to explaining the percentage variations in the mean rate of income growth is the third highest among all determinants of growth, suggesting that the effect of freedom on growth is more pronounced than previously measured. It is argued that freedom will enable individuals to expand the range of socio-economic opportunities and to establish greater control over the human environment in order to improve material well-being.
