In this study we compare the income distributions for men and women in Poland in 2014. To examine the differences in the entire range of income values we utilize the hazard function approach. A flexible hazard-function based estimator in the presence of covariates (education, age, etc.) is used to construct conditional density and cumulative distribution functions. Then, we decompose the differences between two distributions using the counterfactual distribution. We estimate also the Lorenz curves for incomes and decompose the differences between the values of the Gini coefficients.
