Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

WP219. Educational mismatches and earnings: are the graduates more penalized for being overeducated?

This paper estimates an extended Mincer wage regression model with Heckman correction for non-random selection using LFS data for Poland for the second quarter of 2013. Significant wage penalties are found to overeducation status as well as positive wage premia for being undereducated, which confirms findings that are found in the literature for other countries. Using Duncan and Hoffman (1981) approach, we find significant positive returns to years of overschooling and negative for underschooling. Young participants of the labour market (graduates) are less penalized for being overeducated, which suggests their overeducation is not necessarily a manifestation of lower ability.

WP216. Does it pay to study abroad? Evidence from Poland

Tertiary education has been perceived in Poland as a key determinant of success in the labour market, as clearly shown by the increase of the net enrolment ratio in tertiary education from 9.8% in 1990 up to 40.9% in 2009. However, as tertiary education becomes more and more popular, it does not signal skills as well as before. It seems that employers may treat students' participation in international exchange programs as a new signaling tool since according to them international students’ skills – both cognitive and non-cognitive – are well above the average. On the other hand, students participating in exchange programs underline a positive impact of studying abroad on their personal development, i.e. on their general skills. Thus, from a theoretical point of view we may expect a positive correlation between studying abroad and wages, which follows from both signaling theory and human capital theory. On the average, 16% of European students report a positive impact of participation in Erasmus exchange program on their incomes, but interestingly, those from the CEE countries, including Polish students, report it much more often. The aim of this paper is to determine whether studying abroad for at least one semester has an impact on wages of higher education graduates in Poland. To answer this question, an extended Mincer wage equation was estimated using OLS on the basis of data from the nationwide tracer survey of Polish graduates conducted in 2007 (Graduate Tracer Study 2007). The hourly net wage rate in the first job after graduating from a higher education institution was the dependent variable in the wage equation. In order to reduce the selection bias, a number of variables were included in the model to reflect students’ abilities and skills, as well as their previous international experience. The results of the analysis show that Polish students who completed at least one semester of studies abroad, enjoy a wage premium of 28% in their first workplace after graduation. Interestingly, this wage premium is particularly high in case of graduates with low abilities and skills and – consequently – of a low social and economic status. This may indicate that studying abroad contributes to a reduction of social inequality.

WP205. The wage premium from parents’ investments in the education of their children in Poland

The aim of this paper is to determine whether parents’ investments in the education of children in Poland have an impact on the wages of the latter in adulthood. To answer this question, an extended Mincer wage equation was estimated using OLS on the basis of data from the nationwide tracer survey of Polish graduates conducted in 2007. The results of the analysis show that parents’ investments in the education of their children have a strong, positive impact on the first earnings after the end of formal education. This relationship is observed when the investment is depicted with the education level of each parent, as well as when represented by the child’s participation in various extra-curricular activities. Furthermore, if any of the above measures of parents’ investment is included in the equation, the wage premium from formal education decreases. In particular, when both these measures of parents’ investments are included in the model, the tertiary education premium declines by about one quarter, while the secondary vocational education and secondary general education are no longer significant determinants of the graduates’ wages (as compared to basic vocational education).
