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.

WP387. The effect of decentralization of government power on the character of public goods provision

What are the institutional drivers of public goods provision? What do we know about the impact of concentration of power on their distribution? The current literature proves the relevance of the allocation of public goods, mostly in the context of economic and social progress. A growing number of empirical studies is focused primarily on public policies that may matter in this context. However, we still know relatively little about institutional factors that may affect public goods provision. In this article we apply econometric and machine learning tools to verify the importance of governmental power decentralization for distribution of public goods. The obtained output implies that indeed concentration of power impacts public goods provision and the results are robust across various quantitative methods. Our conclusions may be of practical relevance also for policymakers.

WP354. Institutional Framework of Central Bank Independence: Revisited

The subject of central bank independence (CBI) and its consequences for monetary policy and economic development has been widely explored in public debate and research discourse. The main aim of the article is to analyze central bank independence, considering the institutional environment in a given country. Our primary focus is on the relevance of de jure provisions for de facto CBI, as well as on the importance of other structural factors. We rely on a dataset consisting of various novel indices to approximate these issues across multiple dimensions and apply advanced econometric tools to investigate our research tasks. The outcome of the study implies that the interrelationships between de jure and de facto CBI are observable. Thus, these conclusions may be successfully applied in institutional design and public policies regarding central banking.

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.
