The Impact of Fiscal Policy on Income Inequality: A Case Study of Pakistan

Abstract

This study investigates the impact of various fiscal policy instruments on the income inequality of Pakistan using an Auto Regressive Distributed Lag (ARDL) model on annual data. We find that direct taxes reduce income inequality, measured using the Gini index, while indirect taxes increase disparities. As the major portion of tax revenues are indirect taxes, the current tax regime of Pakistan does not achieve income redistribution. Similarly, development expenditures have significantly reduced income inequality, likely through the creation of employment opportunities. On the other hand, the overall fiscal deficit increases income inequality, due to a rising public debt financed by (regressive) indirect taxes. This study suggests that in the case of Pakistan, where direct taxes are low, a large shadow economy exists, and weak tax administration prevails, an increase in development expenditures and broadening of the tax base of direct taxes should be the main fiscal policy tools for income redistribution. Moreover, persistent high fiscal deficits in the long run should be avoided. Finally, governments should reduce educational inequalities and promote democratic values in the country in order to promote greater fairness in distribution of income.
