Objective: Despite the economic changes of countries over the past years, there is still an income gap between different social groups, and this has caused economists and policymakers to pay more attention to different dimensions of income distribution. This research aims to investigate the income inequality of Iran and selected business partners.
Methods: The data collected between 2002-2021 were analyzed using Stata software. Variables affecting income inequality include globalization, entrepreneurship, global governance, GDP per capita and inflation rate.
Results: After confirming the cross-sectional independence and checking the significance of the variables, the Pedroni and Kao cointegration tests were used and the existence of a long-term equilibrium relationship between the variables of the model was confirmed. Then, two-way random effects were estimated with the Chow and Hausman tests of the panel data model.
Conclusions: According to the results, the globalization index has a negative and significant effect on income inequality. Also, the coefficients of the entrepreneurship and global governance variables are positive and significant. Regarding the impact of the GDP per capita variable on income inequality, the coefficient has become positive and significant, and it shows that most of the investigated countries are in the upward part of Kuznets' inverted U hypothesis. The inflation rate variable also has a negative and significant sign, indicating that as the inflation rate level of these countries increasesm the amount of income inequality decreases. Although it has been emphasized in some studies that there are no clear results in this regard.
