Wage Differences in Poland Related to Employment Form

Summary/Abstract: The article compares different employment forms existing in Poland and analyses wage gaps existing between them. The first part contains a literature review on dual labour markets and substandard employment forms. The second part describes the types of employment contracts existing in the Polish labour market and the scale of their use; it also compares the share of substandard employment forms in Poland and other EU countries. The third part presents the results of an empirical examination. Based on labour market survey data of 2016, the authors analysed the wage lag present in net remuneration between employment contracts concluded for a specified time and for an indefinite period, as well as fee-for-task agreements (civil contracts). To this aim they used a decomposition of the wage equation based on Oaxaca–Blinder method, which makes it possible to isolate the wage lag in a correct way, after excluding the effects of differences in the individual characteristics of employees, their profession and workplace. The results of the research confirmed the existence of wage differentials, both in raw and adjusted data, between different employment forms.
