Abstract

This article explores the development of part-time employment in Central and Eastern Europe and compares it to Western Europe. On the macro level it examines the role of the business cycle and its effect on part-time employment in the two groups of countries since 2001. The key result reveals that contrary to the West, the business cycle development exerts a significant negative effect on the part-time employment rate in Eastern Europe. When the economy operates below its potential, part-time employment tends to grow more than full-time employment. This finding is consistent with the labour demand effect and reflects the pursuit of flexibility by firms as well as the adjustment in composition of employment to changing economic conditions. The countercyclical effect is even stronger for involuntary part-time employment. Separate analyses of individual demographic groups of workers reveal a significant negative effect of the business cycle on part-time employment of older workers and male prime-age workers in Eastern Europe. In contrast, the effect is insignificant for young workers and unclear for prime-age women.

Abstract

Already classical economists took interest in the role of wages and wage formation mechanisms, as well as in their influence on other components of the labour market. This article aims to systematise contemporary approaches to wages as one of the labour market components that have been developed within major economic theories. The systemization will serve as a basis for identifying main interactions between wages and other labour market components, such as labour supply and demand and labour market disequilibrium. The article presents major concepts formulated within neo-classical and Keynesian theories, labour market segmentation theories, efficiency wage theory, rent-sharing and rent-extraction theories, theory of job search, and search-and-matching models. One of the conclusions arising from the discussion is that the evolution of contemporary labour markets is a challenge for researchers seeking wage formation models adequately describing the real-life circumstances.

Abstract

Low-skilled immigration has been argued to lower the price of services that are close substitutes for household production, reducing barriers for women to enter the labor market. Therefore, policies that reduce the number of low-skilled immigrants who work predominantly in low-skilled service occupations may have an unintended consequence of lowering women’s participation in the labor market. This article examines the labor supply impact of the Legal Arizona Workers Act (LAWA), which led to a large decline in the low-skilled immigrant workforce of the state. The analysis shows no evidence that LAWA statistically significantly affected US-born women’s labor supply in Arizona. This finding is partly explained by an increase in native workers in household service occupations due to LAWA, which offset the decline in immigrants in these occupations and caused the cost of household services to be relatively uninfluenced by the passage of LAWA.

Abstract

Parental leave and child care are important instruments of family policies to improve work–family balance. This paper studies the impact of the substantial change in Germany’s parental leave system on maternal employment. The aim of the reform was to decrease birth-related maternal employment breaks by providing more generous parental benefits for a shorter period of time. Using the German Socio-Economic Panel data for 2002–2015, I exploited quasi-experimental variation in the benefits to estimate the impact of the reform. I incorporated the mother’s decision to substitute her care time with the public child care. To control for the availability of child care, I used spatial and temporal variation in the availability of childcare slots. Overall, I did not find significant changes in maternal employment during the first three years of motherhood after the reform implementation. Only for high-income mothers, the reform produced a significant decrease in the employment participation during the first year of leave and an increase in employment probability after the benefits expired. The empirical findings suggest that the restriction in the childcare availability became an important constraint for the employment effect of the reform.

Abstract

Low labour market participation, together with the high effective tax wedge at low wage levels, create a fertile ground for the introduction of the in-work benefits (IWB) in Serbia. Our paper provides an ex-ante evaluation of the two IWB schemes, directed at stimulating the labour supply and more equal income distribution. The methodological approach combines the tax-and-benefit microsimulation model with the discrete labour supply model. Our results show that both individual and family-based IWB schemes would considerably boost labour market participation, although family-based benefits would have disincentivizing effects for the secondary earners in couples. Most of the behavioural changes take place among the poorest individuals, with significant redistributive effects.

Abstract

This study investigates the incidence of overeducation among graduate workers in 21 European Union countries and its underlying factors based on the European Labor Force Survey 2016. Although controlling for a wide range of covariates, the particular interest lies in the role of fields of study for vertical educational mismatch. The study reveals country differences in the impact of these factors. Compared to Social sciences, male graduates from, for example, Education, Health and welfare, Engineering, and ICT (Information and Communication Technologies) are less and those from Services and Natural sciences are more at risk in a clear majority of countries. These findings are robust against changes of the standard education. Moreover, some fields show gender-specific risks. We suggest that occupational closure, productivity signals and gender stereotypes answer for these cross-field and cross-country differentials. Moreover, country fixed effects point to relevant structural differences between national labor markets and between educational systems.

Abstract

The aim of this study was to detect possible differences between farmed and wild-living raccoon dogs. Analysis of polymorphism in 15 microsatellite sequences led to the conclusion that raccoon dogs raised on Polish farms and wild raccoon dogs living in Poland are two genetically distinct groups of animals. Wild Polish raccoon dogs are genetically more similar to the population of wild animals from the Kaliningrad Region than to farmed animals. The analysis of microsatellite loci showed clear genetic differences between farmed and wild-living populations of raccoon dog, despite only 50 years of isolation of the two groups of animals. The farmed population was characterized by higher genetic variation than the wild-living population. On the basis of the analyses three microsatellite loci (INU014, Ren13J22 and Ren41D20) were proposed for determination of the origin of animals that have escaped from farms.

Abstract

This study was designed to determine the degree of genetic distinctiveness between farmed and wild foxes (Vulpes vulpes). Analysis of polymorphism in 16 microsatellite sequences led to the conclusion that red foxes raised on Polish farms and wild foxes living in Poland are two groups of genetically distinct animals. Farmed Polish foxes are genetically more similar to the population of wild animals from North America than they are to the free-living population in Poland, as confirmed by the fact that the farmed animals are descended from animals raised in Canada.

The small genetic distance between wild Canadian foxes (indicated as the progenitor of farmed Polish foxes) and farmed Polish foxes possibly suggests that the differences between the farmed and wild Polish populations may result from the fact that Canadian and Polish foxes took separate evolutionary paths.
