“…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.

“…Za pomocą krzywej Lorenza można oszacować indeks Giniego (Gini, 1914), który jest miarą koncentracji rozkładu zmiennej losowej. Miary tej używa się do statystycznego opisu szerokiej gamy czynników społeczno-gospodarczych; najczęściej jest ona stosowana do określenia stopnia nierówności w podziale dochodów (Trzcińska, 2021).

Education should be able to keep up with the changes taking place in the surrounding reality, both in terms of its content and mode of work. In addition to technological progress, these changes have been recently stimulated by the COVID-19 pandemic and the related restrictions which enforced distance learning. These circumstances pose a question about the effectiveness of online learning. The aim of this paper is to compare the effectiveness of distance and classroom learning. The analyses are based on the results of the final exams in mathematics obtained by first-year fulltime students majoring in finance and accounting at the University of Lodz in the years 2018/2019 (classroom learning) and 2020/2021 (distance learning). These students’ scores achieved in the basic-level matura exam in mathematics served as a point of reference. The teaching mode remained the same throughout the entire cycle of classes in the aforementioned years. The assessment of the effectiveness of learning was based on the Lorenz curve and the Gini coefficient, which is commonly used by economists to determine income inequality. However, it can also be applied to any kind of data of an unequal distribution. The conducted research showed no significant differences in terms of the effects of distance learning and classroom learning, which proves that the university maintained a high quality of education despite the introduced change in the mode of teaching. The descriptive statistics relating to the verification of the mathematical knowledge in the selected student groups – in particular the left-sided asymmetry – indicate a slight predominance of positive results achieved in the final exams during distance learning compared to the results obtained during classroom education, which also applies to the matura exams. However, these differences are not significant as they differ by approximately 0.1 p.p.

“…The condition for consumption is to have sufficient resources to purchase the goods and services mentioned (Canberra Group, 2011). The knowledge of the income distribution is the basis for assessing the material situation of socio-economic groups of households (Dolls et al, 2019;Trzcińska, 2020;Trzcińska, 2021;Kuznets, 2019;Bartošová, Bína, 2009). A lack of funds to meet the needs at the desired level implies a risk of poverty for households and may lead to social exclusion of its members due to the inability to participate in social life (Ledić, Rubil, 2019;Mysíková et al, 2019;Forster, Pearson, 2018;Salejko-Szyszczak, Szczepaniak, 2017;Wolf, 2009).…”

Income distribution can cause large-scale transformations in social structure, as well as in the quality of life. The aim of the paper is to compare the economic situation of households in Poland and the Czech Republic. The level and the dispersion of income distributions of households and the level of poverty due to the selected socio-economic characteristics of a respondent or a household are analysed. All the conclusions are based on the results of European Quality of Life Surveys. To describe the distribution of net equivalent income, the Singh-Maddala model is used. The estimation parameters are obtained by means of the maximum likelihood method. The descriptive statistics characterising the total situation in the Czech Republic and Poland, as well as in selected socio-economic groups, are calculated. To analyse the extent, depth and severity of poverty in the countries in question, the aggregate indices are obtained. The conducted research shows a high similarity for both distribution of equivalent income and the socio-economic groups particularly exposed to monetary poverty.
