Effects of Being in an Occupation – Is ISCO 1 Digit Classification Enough to Model Wages in Poland?
Effects of Being in an Occupation – Is ISCO 1 Digit Classification Enough to Model Wages in Poland?

Summary/Abstract: Contrary to neoclassical assumptions of perfect competition, there is a consensus that factors affecting wages include sex, level of education, age, job experience, occupation, post, work-related responsibility and a whole set of personality traits. The paper presents an econometric model that allows to explain wage differences in Poland and extends analyses of wage determinants in Poland by taking into account occupations broken down in accordance with the 2-digit level of International Standard Classification of Occupations (ISCO). The analysis shows that ISCO 2 digit level is an important and statistically significant determinant of wages in Poland, while models of wages basing on ISCO 1 digit might be not enough to properly capture the role of occupations.
