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.

WP490. Employers’ Discrimination against Fathers and Mothers Taking Parental Leave: Evidence from a Choice Experiment

This study provides causal evidence on the hiring and pay penalties associated with taking parental leave of varying lengths. We investigate how deviations from prevailing social norms, in the form of non-standard leave-taking behavior by mothers and fathers, affect their employment outcomes. We also compare the parental leave penalties with those linked to unemployment to disentangle the determinants of these penalties and to identify the mechanisms through which they operate. To this end, we conducted a discrete choice experiment with 997 managers, who evaluated hypothetical job candidates differing in the length of employment interruptions due to parental leave. Using a conditional logit model, we find that both mothers and fathers face disadvantages in hiring and remuneration when taking longer parental leave. Notably, fathers are penalized for taking any parental leave, though the penalties are more severe for longer leave. These poorer employability prospects stem from managers perceiving such fathers as less available for work. Meanwhile, mothers receive hiring and pay bonuses for taking shorter leaves, stemming from employer perceptions of such mothers as more available, competent, and motivated.

WP419. Structural Labour Market Change and Gender Inequality in Earnings

Research from the US argues that women will benefit from a structural labour market change as the importance of social tasks increases and that of manual tasks declines. This article contributes to this discussion in three ways: (a) by extending the standard framework of task content of occupations in order to account for diversity of social tasks; (b) by developing measures of occupational task content tailored to the European context; and (c) by testing this argument in 13 European countries. Data are analysed from the European Skills, Competences, Qualifications and Occupations Database and the European Structure of Earnings Survey. The analysis demonstrates that relative to men the structural labour market change improves earnings potential of women working in low- and middle-skilled occupations but not those in high-skilled occupations. Women are overrepresented in low paid social tasks (e.g. care) and are paid less for analytical tasks than men.

WP207. Return to vocational education. Evidence from Poland

Vocational education in upper-secondary school has been perceived for many years as being inferior to general education, in spite of the fact that vocational education graduates enjoy a faster transition from school to work and are more likely to have a permanent first job. As a consequence of the reform of the educational system that took place in Poland in 1999, the enrolment ratio in vocational schools has fallen dramatically. The empirical evidence in the literature on the returns to vocational education is limited. This study fills that gap and looks into wage premium for workers with vocational education in Poland before and after the reform of the educational system. The relative returns to different types and levels of education were estimated using a standard Mincerian wage equation
framework. The empirical analysis concentrated on a comparison of the relative benefits of vocational and nonvocational education. The results showed that vocational education graduates have, on average, a higher probability of finding a permanent job, and secondary-vocational education graduates receive higher earnings than secondary general education graduates in Poland. However, wages of vocational education graduates are lower than those of secondary general education. In spite of this, the decreasing number of vocational education graduates post-reform has contributed to reducing this gap.

WP204. Evolution of the public-sector wage premium in Poland

The aim of this paper is to estimate the adjusted sectoral wage gap in Poland in the period 1999–2012. We use a set of individual data from the survey on the structure of earnings by occupations (SEO) carried out by Central Statistical Office in Poland (CSO) every two years for entities with more than nine employees. We apply quantile regression and the Ñopo decomposition method to address several methodological problems of wage differential analysis. We show that, after controlling for structural differences in employment, there is no clear trend in the evolution of the adjusted public-sector wage premium in Poland in recent years. The parametric approach indicates a positive and growing premium, with significant variations across different parts of wage distribution. The non-parametric approach yields different results, indicating a negative premium with no clear trend in the period 1999–2012, with a declining public-sector wage penalty in recent years.

WP127. We all do it, but are we willing to admit? Incentivizing digital pirates' confessions.

In this study we try to assess the prevalence of illicit downloading in the market of audio books and the willingness to admit to such practices. We compare the Bayesian Truth Serum (Prelec, 2004) treatment in which truthful responses and precise estimates are rewarded to the control treatment with a flat participation fee. We find a sizable treatment effect - incentivized ?pirates? admit approximately 60% more often than the non-incentivized ones.
