Working Papers

The WNE Working Papers series has been published by the Faculty of Economic Sciences at the University of Warsaw since 2008.

The WNE Working Papers series provides a fast, open channel for disseminating research conducted at the Faculty of Economic Sciences, University of Warsaw. The papers hosted here are working versions (pre-prints) and may evolve as authors refine their analyses, incorporate feedback, or progress through formal peer-review. What you read is the current version released by the authors, timestamped and assigned DOI/ISSN identifiers to ensure precise citation and version tracking. Copyright remains with the authors, who may, at any time, upload a revised file or add a note directing readers to a later, peer-reviewed publication.

The Working Papers series accepts articles by research employees of the Faculty and publications from conferences organised at the Faculty of Economic Sciences at the University of Warsaw. Articles should be original research papers which have not been previously published, on the subject of economics.

WP252. The output employment elasticity and the increased use of temporary contracts: evidence from Poland

The paper investigates how increased use of temporary contracts has affected employment elasticity with respect to output in Poland. Our empirical analysis covers the period of 1996-2016, with particular focus on the years 2001-2016. Several econometric tools are used to explore the relation between growth in GDP and employment. Our study shows that widespread adoption of temporary contracts contributes positively to total employment elasticity. However, what we have observed is that the share of temporary contracts has increased, but the total employment elasticity has decreased. We related this to an inverse relationship between the growth of permanent and temporary employment and the opposite trends in output elasticities of temporary and permanent employment.

WP235. An Institutional Approach to Trade Unions’ Density. The Case of Legal Origin and Political Ideology

Which institutions may be important in terms of trade unions' density and how significant they are? However, trade unions' status is very different among states, they are still a very meaningful component of labor markets. In this paper we contribute to the debate on the institutions, which may affect the outcome of trade unions in different legal systems. Firstly, we draw on theoretical underpinnings of trade unions' activity and density. Then, we conduct an empirical analysis of the relationships between trade union density in a particular country, its legal origin and government's ideology. In this way the paper enriches an underexploited niche in institutional research devoted to labor market issues.

WP220. De jure and de facto institutions – disentangling the interrelationships

In this paper we contribute to the debate on the nature of institutions and their economic effects by extending the focus to the de jure – de facto institutional distinction. Firstly, we define and conceptualize de facto institutions, as well as elaborate on their place in the broad institutional system and identification. Then we investigate the possible interrelationships between de facto and de jure institutions. Finally, we make a link between these interrelationships and economic outcomes. In this way the paper fills an underexploited niche in institutional research, which is a major background for law and economics.

WP13. When Eastern Labour Markets Enter Western Europe CEECs. Labour Market Institutions upon Euro Zone Accession

This paper reviews the literature on the labour market institutions in European Union Member States in the context of monetary integration. Traditionally, labour markets are a key concept in the optimal currency area theory, playing the role of the only accommodation mechanism of asymmetric shocks after the monetary unification. There are several theoretical frameworks linking the institutional design of the labour market to the potential effectiveness of monetary policy in the context of currency areas. Many empirical studies addressed these issues too, yielding important policy implications for labour market reforms in the process of monetary unification. However, there seem to be "white spots" in this patchwork, which may actually be particularly useful from the perspective of CEECs upon the accession to the euro zone. We suggest these research directions encompassing labour supply and theoretical frameworks of labour market flexibility benchmarking in the context of monetary integration.
