Income and Inequality Measures in Households in Czech Republic and Poland based on Zenga Distribution

Anotace: Income is one of the appropriate indicators for the evaluating of living standards of people, so it is important to examine the distribution of income and its degree of differentiation in society. A lot of research has been directed at describing empirical distributions by the theoretical model. In 2010 Zenga proposed a new threeparameter model for economic size distribution. The aim of this paper was to apply Zenga model to income distribution in the Czech Republic and in Poland. The results of conducted approximations obtained by means of D’Addario’s invariants methods confirm that the Zenga distribution is a good income distribution model which can be successfully applied to income inequality analysis and income distribution comparisons both in the Czech Republic and in Poland.
