“…The latest works consist of very high accuracy with empirical distribution for the threeparameter models income for the Polish data (Brzeziński, 2013;Kot 2000;Trzcińska, 2020;Trzcińska 2021;Wałęga, Wałęga, 2021;Sulewski, Szymkowiak, 2023). Research on income distributions in the USA indicates a good fit of two-parameter and three-parameter distributions to the empirical data (Majumder, Chakravarty, 1990;Drăgulescu, Yakovenko 2001;Clementi, Gallegati, 2005).…”

Research background Household income is one of the most important economic categories depending on various factors, in particular on the level of education of the head of the household. Salaries are treated as the market valuation of graduates made by employers. Hence, the question arises of how the education system affects the distribution of household income, in particular in the group of people with higher education. Purpose The aim of the paper is to apply the Singh-Maddala model to describe the income distribution of people with primary, secondary and higher education in Poland and the USA. On the basis of numerical characteristics and measures of income inequality, the situation of education, in particular higher education, and its impact on household income in the analyzed countries were assessed. Research methodology The study used data from the Luxembourg Income Study Database (LIS) from 2020. All analyzes were based on the Singh-Maddala model. The maximum likelihood method was used to estimate the model parameters. Results The analysis showed that the higher the level of education, the better the income situation of the household. In Poland, salaries in the group of people with higher education are the most unequal, while in the USA the greatest income inequalities occur in the group of people with primary education. Novelty The paper describes the issue of household income distribution and income inequality, which is an important and current socio-economic problem. To describe and analyze the economic situation of the household incomes of people with different levels of education in Poland and the USA statistical data from the Luxembourg Income Study Database (LIS) was used. Empirical studies conducted for different samples add significantly to existing knowledge on the topic.

Research background Income inequalities between women and men often constitute an important area of research related to social inequalities. Differences in incomes between genders are frequently analyzed in the context of gender equality, social justice, and economic equity. Disparities in wages between women and men are observed in many societies. A key tool in studying wage and income distributions, as well as income inequalities, is the approximation of theoretical models to empirical data. Another important tool is the use of income inequality measures. Research on income distributions between women and men is significant for various reasons, including facilitating an understanding of social and economic inequalities. Purpose In Europe, there is diversity in economic models, with individual countries adopting different approaches to organizing their economic systems. The paper considers four European countries representing diverse economic approaches. A comparative analysis of income inequality between men and women was conducted in the countries under consideration. Research methodology The study used data from the Central European Bank from 2017. All analyzes were based on the Dagum model. The maximum likelihood method was used to estimate the model parameters. The Theil coefficient decomposition was also applied. Results The analysis reveals that men earn the highest incomes in all countries. Visualization of the Lorenz and Zenga curves, along with calculated inequality indices, showed that the greatest income inequalities occur in women’s incomes in all cases. Interestingly, it was found that men’s incomes make the largest contribution to the overall income inequalities. Novelty The paper explores the topic of income inequality, which is a significant and contemporary socioeconomic challenge. It utilizes statistical information from the Eurosystem Household Finance and Consumption (HFCS) to examine and assess the financial status of households, focusing on both genders, in Finland, Germany, Poland, and Spain.
