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.

WP507. Did Living Standards Converge? Beyond GDP in Post-Socialist Europe and Russia

Three decades after the fall of communism, GDP convergence is widely cited as evidence that the post-socialist transition succeeded. But GDP is a narrow measure of living standards. This paper asks whether convergence toward Western Europe holds up once health, inequality, and leisure are also taken into account. We construct a comprehensive welfare measure for Poland, Czechia, Hungary, Slovakia, and Russia, benchmarked against Germany, covering the 1980s through 2022. In every country, welfare relative to Germany falls well below what GDP alone would suggest. Russia’s welfare stands at roughly half its GDP level, driven by the post-Soviet mortality crisis and extreme inequality—challenging characterisations of Russia as a “normal” middle-income country. Hungary, conventionally grouped with the Visegrad convergence successes, suffers a substantial welfare shortfall driven by decades of poor health outcomes. Poland emerges as the strongest performer in convergence dynamics. Life expectancy is the largest contributor to this gap.

WP470. The Impact of Railway on the Regional Economic Development and Social Mobility in the Congress Kingdom of Poland

We estimate the impact of railway construction on local populations in Russian Poland in the 19th century. The initial wave of railway expansion outpaced economic demand. From the late 1860s onward, locations connected to the railway network experienced significantly higher population growth. The economic effects of the connection to the railway network increased over time. State-funded military railway lines generated a smaller impact than private-owned lines. We also study the impact of the railway connection on social mobility proxied through a number of notable people born in a given city. However, we do not identify any robust impact.

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.
