Financial inclusion is considered as a critical factor that contributes to the reduction of income imbalance. This paper uses a two-stage least squares (2SLS) model and two different financial inclusion index to examine the impact of financial inclusion on income inequality in 22 transition economies over 11 years from 2005 to 2015. The paper finds that there was a negative relationship between the financial inclusion index and the GINI coefficient. The paper also suggests some policy recommendations to reduce income inequality through developing financial inclusion.
