Improving people’s quality of life and increasing the level of public welfare are among the goals defined by different governments around the world. In meeting such goals, reducing income inequality is one of the factors that play a major role. Therefore, it is of high significance to figure out the factors related to income inequality. The present study was conducted to investigate the relationship between income inequality, economic growth and misery index in Iran, and in this regard, time series data related to the years 1971-2019 have been used. The income inequality index in the present study is the Gini coefficient and to estimate the research model, Autoregressive Distributed Lag (ARDL) method has been used. The results indicated that increasing as the misery index increases, income inequality in Iran will increase as well. Moreover, the ratio of real government spending to real GDP and economic growth has a positive effect on increasing inequality and the ratio of total real investment to real GDP and a dummy variable for revolution have a negative effect on income inequality.
