Working Papers

Seria wydawnicza WNE WORKING PAPERS prowadzona jest przez WNE UW od 2008 r. i jak dotąd opublikowano w niej ponad 400 prac.

Seria WNE Working Papers służy szybkiemu upowszechnianiu wyników badań prowadzonych na Wydziale Nauk Ekonomicznych UW. Publikowane tu teksty mają charakter wersji roboczych (pre-printów): mogą być uzupełniane lub poprawiane w miarę postępu prac nad tekstem i procesu wydawniczego. Prezentujemy aktualną wersję udostępnioną przez autorów, opatrzoną datą oraz identyfikatorami DOI/ISSN – co ułatwia jej cytowanie i śledzenie kolejnych iteracji. Każdy dokument zachowuje pełne prawa autorskie swoich twórców, a w przypadku późniejszych zmian, autorzy mogą w dowolnym momencie zamieścić zaktualizowany plik lub wskazać miejsce ostatecznego wydania.

Do serii WORKING PAPERS przyjmowane są artykuły pracowników naukowych WNE UW oraz publikacje z konferencji organizowanych na WNE UW. Artykuły powinny dotyczyć ekonomii, mieć charakter oryginalnych prac badawczych, nie być wcześniej publikowane. Przyjmowane są wyłącznie teksty w języku angielskim.

Prace prosimy przesyłać e-mailem na adres: siC16*4\rK/{y5NuUAkJEq@='#o]#[kY2wzsvMT8onmPFd7JaBNW{01v\

Prosimy przesyłać dwa pliki:

WP320. Why wealth inequality differs between post-socialist countries?

We provide the first attempt to understand how differences in households' socio-demographic and economic characteristics account for disparities in wealth inequality between five post-socialist countries of Central and Eastern Europe. We use 2013/2014 data from the second wave of the Household Finance and Consumption Survey (HFCS) and the reweighted Oaxaca-Blinder-like decompositions based on recentered influence function (RIF) regressions. Our results show that the differences in homeownership rates account for up to 42% of the difference in wealth inequality measured with the Gini index and for as much as 63-109% in case of the P50/P25 percentile ratio. Differences in homeownership rates are related to alternative designs of housing tax policies but could be also driven by other factors. We correct for the problem of the 'missing rich' in household surveys by calibrating the HFCS survey weights to top wealth shares adjusted using wealth data from national rich lists. Empirically, the correction procedure strengthens the importance of homeownership rates in accounting for cross-country wealth inequality differences, which suggests that our results are not sensitive to the significant underestimation of top wealth observations in the HFCS.

WP212. Post-Socialist Constitutions: The De Jure - De Facto Gap, Its Effects and Determinants

In this paper we aim to contribute to the debate on constitutional rules and their economic effects by extending the focus to the de jure – de facto constitutional gap. Firstly, we provide evidence that the size of this gap matters as non-compliance lowers the effectiveness of the constitutional commitment mechanism. Secondly, we identify several explanans of this gap, in particular relating to the democratization process, political conflict, age and comprehensiveness of the constitution. We base the conclusions on an empirical study for the unique setting of the post-socialist countries of Europe and Asia, which all enacted new constitutional frameworks after 1989, and argue that the constitutions in these countries acted primarily as blueprints.

WP209. Reassessing the Economic Effects of Post-Socialist Constitutions Using the Synthetic Control Method

In response to the problems of endogeneity and causality in comparative studies with relatively small sample sizes, a new statistical approach has recently been developed, called the synthetic control method. In this paper we apply this method to reassess the effect of constitution-making in post-socialist countries of Europe and Asia on performance of these countries in the field of economic reforms during the post-1989 transition. We first verify the existence of such effects and evaluate their statistical significance. Then we search for the explanation of these effects and their magnitude focusing on the characteristics of these constitutions and the solutions that they envisage (structural provisions, bills of rights and enforcement mechanisms). Thanks to employing this approach we are able to avoid several technical caveats that have arisen in earlier studies and verify the validity of their conclusions. In addition, we obtain country-specific results for each individual post-socialist state, as well as formulate detailed insights regarding the actual mechanisms or channels of influence of the constitutional framework on economic reforms.

WP181. Economic Effects of Post-Socialist Constitutions Revisited (nearly) 25 Years from the Outset of Transition

Post-socialist transition taking place since 1989 in countries of Central and Eastern Europe, as well as later in Central and Southwestern Asia, brought about simultaneous changes of their political and economic systems, requiring the establishment of new constitutional frameworks. In this paper we study the effects of post-socialist constitutional change on economic policy decisions of countries involved in this process. As nearly 25 years have passed from the outset of transition, the data allows to conduct an empirical study based on an econometric model confirming the relevance of several constitutional rules in this respect, e.g. regarding the model of government and constitutional judiciary. Based on the results, recommendations are made for countries, where the transition process has been slow and unsuccessful.
