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.

WP411. Inequality and happiness: the role of income versus wealth inequality

There are conflicting theories about whether individuals like or dislike inequality, or in other words, whether living in an unequal country increases or decreases their subjective well-being. The empirical literature has also not yet reached a consensus. In this paper, we add a new perspective to the inequality-happiness puzzle. First, we study not only income inequality, but also wealth inequality, which has so far been overlooked in the happiness literature. Second, we reach beyond the usually studied Gini coefficient and top income shares, looking also at the other parts of income or wealth distribution. Using data from the integrated World Values Surveys and European Values Surveys for over 50 countries, matched with World Inequality Database data over the years 1981-2020, we find that individuals are happier with increases in the top 10% and top 1% shares of wealth and less happy with increases in the middle 40% share of either wealth or pre-tax income. Increasing the bottom 50% share of after-tax income also makes individuals happier, suggesting that they favor income redistribution. We offer possible explanations for these findings.

WP360. Don’t Worry, Be Happy – But Only Seasonally

Current scientific knowledge allows us to assess the impact of socioeconomic variables on musical preferences. The research methods in these studies were psychological experiments and surveys conducted on small groups or analyzing the influence of only one or two variables at the level of the whole society. Instead inspired by the article of The Economist about February being the gloomiest month in terms of music listened to, we have created a dataset with many different variables that will allow us to create more reliable models than the previous datasets. We used the Spotify API to create a monthly dataset with average valence for 26 countries for the period from January 1, 2018, to December 1, 2019. Our study almost fully confirmed the effects of summer, December, and number of Saturdays in a month and contradicted the February effect. In the context of the index of freedom and diversity, the models do not show much consistency. The influence of GDP per capita on the valence was confirmed, while the impact of the happiness index was disproved. All models partially confirmed the influence of the music genre on the valence. Among the weather variables, two models confirmed the significance of the temperature variable. All in all, effects analyzed by us can broaden artists' knowledge of when to release new songs or support recommendation engines for streaming services.

WP(15/2018)274. Top incomes and subjective well-being

WP274. Top incomes and subjective well-being

We use data from the World Wealth & Income Database, the European Values Surveys and World Values Surveys to estimate the relationship between top income shares and subjective well-being in a sample of 35 countries observed between 1980s and 2010s (139 surveys and more than 200,000 respondents). Results show that top 1% income shares are positively associated with happiness, but not with life satisfaction. The effect is present in a subsample of Western countries. We discuss possible explanations for the positive association between top income shares and happiness.

WP256. Diagnosing unhappiness dynamics: Evidence from Poland and Russia

This paper studies the determinants of changes in unhappiness rate (low happiness, poverty of happiness, misery) over time. We focus on two post-socialist countries, Poland and Russia, which experienced radical social and economic transformations since the collapse of communism. Using data from the Polish Social Diagnosis project for 1991-2015 and data from the Russian Longitudinal Monitoring Survey for 1994-2014, we investigate the microeconomic determinants of spectacular declines in unhappiness rates observed in the studied periods in Poland (a 56% fall in unhappiness) and Russia (a drop in the range from 46 to 75% depending on the unhappiness threshold chosen). Using a nonlinear decomposition methodology, we split the overall decreases in unhappiness rates into characteristics effects (related to the changing distribution of unhappiness-affecting factors) and coefficients effects (due to changing returns to the unhappiness-affecting factors). Our results show that unhappiness reductions in both countries were mostly driven by coefficient effects, while characteristics played a smaller, but a non-negligible role. In both countries, income growth accounted for about 15% of the total unhappiness reduction. In Russia, this effect was doubled by growing return to income as unhappiness-protecting factor, while in Poland income has been losing protecting power and in overall income had an unhappiness-increasing effect. For Russia, another strong unhappiness-protecting factor was return to employment. In case of Poland, good self-rated health and having children explains additional 15-20% of the unhappiness reduction.
