Mincer´s approach that is usually used for wage determinant measuring is based on human capital theory where single personal characteristics are reflected. This theory sees the wage to be determined by quality of education, general working experience, specific working experience already gained in working process, and other qualities free of education and working experience. Empiric literature (Ashenfelter, Layard, & Card, 1999) proved the validity of Mincer´s wage function in basic and modified versions also in countries with different institutional structure. The ratio of education and working experience for explanation of wage differences differs from country to country and moves from 30% - 50%.
