Abstract

South Africa continues to face high inequality levels despite its progressive tax and extensive social protection systems. We compare the dynamic impact of fiscal policy on the distribution of incomes, wages, and wealth in South Africa from 1993 to 2019. For this purpose, we use a time varying parameter vector autoregression to estimate the impact of direct tax revenue and total transfer spending on three distinct inequality datasets. The analysis of various dimensions of inequality is the main contribution of the paper as the literature typically focuses on income inequality. A second contribution lies in the incorporation of time varying effects which enables the analysis of the changing relationship between fiscal policy and inequality. The results suggest that this relationship is indeed time-varying and that the impact of direct taxes and transfers differs markedly across the inequality dimensions, both in terms of magnitude and sign. Overall, we find that both transfers and direct taxes have not significantly reduced income, wage or wealth inequality in South Africa.
