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.

WP520. An Eye for an Eye – The Study of Negative Reciprocity. Evidence From a Game Show

The proposed research is an attempt to analyse the tendency to take a revenge revealed by the participants in the television program "Ten to One" and its relationship with gender, education, and demographic variables of a player. Choices made by participants consist of indication of a participant who will answer the next question. Since this reduces the ones probability of winning the episode, the feedback can be considered as a negative reciprocity or simply: revenge.

WP244. Belief-based and taste-based gender discrimination. Evidence from a game show

Gender discrimination, based on taste or on perception of competence, remains to be a likely contributor to females' lower wages and slower professional advancement. In this project we use a novel data set of decisions made by participants of the Ten to One TV show. During the game, contestants repeatedly nominate the next person to answer a question. Being nominated reduces one's probability of eventually winning the game. General tendency to nominate one gender more often than the other signifies taste-based discrimination against this gender. The construction of the game makes it relatively more profitable to nominate the most competent rather than the least competent opponents in some strategic circumstances, which allows to identify biased perception of the two genders' competence. Having analyzed over 6000 decisions from 117 episodes aired in the last 21 years we find clear evidence of belief-based discrimination against females, yet taste-based in favor of them.

WP(11/2014)128. Gender Wage Gap in Poland ? Can It Be Explained by Differences in Observable Characteristics?

Authors: Goraus-Tańska Karolina, Tyrowicz Joanna
The raw gender wage gap over the period 1995-2012 amounts to app. 9% of hourly wage and is fairly stable. However, the raw gap does not account for differences in endowments between genders. In fact, the adjusted wage gap amounts to as much as 20% on…

WP128. Gender Wage Gap in Poland ? Can It Be Explained by Differences in Observable Characteristics?

The raw gender wage gap over the period 1995-2012 amounts to app. 9% of hourly wage and is fairly stable. However, the raw gap does not account for differences in endowments between genders. In fact, the adjusted wage gap amounts to as much as 20% on average over the analyzed period and shows some cyclical properties. The estimates of adjusted gender wage gap do not seem to exhibit any long-term trends, which suggest that in general neither demographic changes nor the progressing transition underlie the phenomenon of unequal pay for the same work among men and women.

WP101. How to perfectly discriminate in a crowd? A theoretical model of crowdfunding.

This paper proposes a theoretical framework to capture the underlying mechanisms of the innovative online crowdfunding. The goal of this work is to emphasize the advantages of crowdfunding platforms over traditional methods of sale, by describing the capabilities unique to such model and processes stemming from them. Namely, the producer's chance for perfect discrimination is discussed, as well as the contributor's role and his decision dilemma. Numerous extensions to the model provide additional insight into crowdfunding platforms.

WP18. Labour Market Racial Discrimination in South Africa Revisited

Discrimination is a significant issue in labour market economics across developed as well as developing countries. In this paper we inquire the actual size of wage discrimination in the Republic of Soutn Africa, accounting for large differences in individual endowments. We apply the Oaxaca-Blinder decomposition as well as propensity score matching to adequately determine the role of discrimination in the wage gaps observed. Although the size of the absolute racial wage gap is enormous, amounting for more than 500%, the actual estimated effect non-attributable to other factors ranges between 45%-55%. This estimator, however, assumes homogenous discrimination across the wage distribution, while data suggest that there are significant educational, sectoral and occupational differentials. To account for these effects, we implement propensity score matching by finding 'statistical twins' of the White population among the Black population, thus we demonstrate how wages differ between these groups in comparable labour market situations. Here too we find that wages for the White are on average approximately 30%, while the effects vary at quartiles of the wage distribution.
