Analyzing the effects of income inequality on public debt in OPEC member states by threshold panel

One of the major problems of developing governments, such as those of OPEC member states, is the government deficit and rising public debt. One of the reasons for this public debt is government policies faced with income inequalities. The opposite side said that the increased income inequality can lead to capital accumulation and thus increase production and tax payments and reduce government debt. The purpose of this study is to investigate the effects of income inequality on government debt at OPEC member countries are in the period 2010 to 2018. The method used is the threshold panel. The research results show that the relationship between income inequality and public debt at the OPEC member states is U-shaped and not linear. In other words, the effects of income inequality on public debt at OPEC member states are like the threshold.
