Why do women get lower pay Tomas Dosedel, 365877 The aim of my project would be the analysis of so called gender pay gap. Gender pay gap shows the difference between average hourly income of men and women. The Czech Republic is with GPG of 23 % in the top three countries according to the gender pay gap. I would like to analyse the reasons and determinants, which causes the gender pay gap. The main research question sounds “Which determinants influence the income of men and women?” Hypothesis 1: The higher the education is, the higher income will one get. Hypothesis 2: The income is positively connected with age – the more work experiences one gets, the higher his or her income is. Hypothesis 3: People in marriage will get higher salaries. I will perform secondary data analysis on the first wave of the Czech Household Panel Survey from 2015 which are available in the Czech Sociological Data Archive online and free of charge. The data source contains all the information needed, such as age, gender, income, educational level and the marital status.
