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: zp9HY'.^y#rPX7oJ[g2}C8iM~/L]#[r`+0CqpO[vXCLRg5Ap'uLxNC-z5

Prosimy przesyłać dwa pliki:

(1) główny tekst bez podania tytułu artykułu oraz autorów (plik DOC/DOCX) oraz

WP369. Determinants of residential real estate prices: Poland case study

Real estate market is important part of economy. Its influence is compounded by sectors related to real properties, such as construction, capital and rental markets. Real estate market specifics such as high capital intensity, rigidity of supply and time lags, make macroeconomic imbalance easy to emerge. Sudden changes of market conditions lead to severe consequences for the whole economy. Hence, house markets are important not only for house investors, real estate developers and financial institutions, but also for governments and central banks.
In this paper we propose to constitutes a comprehensive overview of house prices determinants. It can be perceived as residential real estate market guide, especially for polish market. In Poland house prices have been consistently increasing since 1990, when transition to a market economy had place. Statistical Pole gets wealthier from year to year, what in conjunction with a strong desire to be on his own, constitutes the powerful driving force of demand for residential real estates
The methods we used in this study are descriptive method and statistical models in addition scatter plots and Pearson's correlation coefficients between variables are presented. Empirical study are based on polish market data, published by Central Statistical Office and Centrum AMRON-SARFiN. We aggregated them for voivodeships and quarters, and concern 2010-2019 period.

WP344. We have just explained real convergence factors using machine learning

There are several competing empirical approaches to identify factors of real economic convergence. However, all of the previous studies of cross-country convergence assume a linear model specification. This article uses a novel approach and shows the application of several machine learning tools to this topic discussing their advantages over the other methods, including possibility of identifying nonlinear relationships without any a priori assumptions about its shape. The results suggest that conditional convergence observed in earlier studies could have been a result of inappropriate model specification. We find that in a correct non-linear approach, initial GDP is not (strongly) correlated with growth. In addition, the tools of interpretable machine learning allow to discover the shape of relationship between the average growth and initial GDP. Based on these tools we prove the occurrence of convergence of clubs.

WP305. What are the determinants of international trade in services? Evidence from firm-level data for Poland

In this paper, we investigate the determinants of firm-level services export performance. Our focus is on three main aspects affecting services export: international capital linkages (FDI relationships), the existence of trade barriers, the demand and supply factors. The estimated models of the export performance include product and firm-level controls, such as foreign demand, firm-level imports, merchandise exporter status and foreign ownership, as well as destination fixed effects, product fixed effects, firm-level fixed effects. We used the Services Trade Restrictiveness Index (STRI) as a proxy to control for institutional trading barriers. The results suggest export-augmenting effects in services caused by both foreign ownership and involvement in activity in merchandise trade. Restrictions on international services market turned out to be significant as well. As far as the heterogeneity of firms is concerned, size of firms, industry and gravity variables such as GDP of trade-partner, distance and the common border have a significant impact on export. The study uses a unique firm-level dataset providing detailed information on services exports for the period of 2010-2015. In contrast to modern studies based on a random sample of firms, we used the entire population of services exporters in Poland.

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.

WP130. Determinants of saving in Poland: Are they different than in other OECD countries?

This paper studies the drivers of total private and household savings in Poland and compares them to those in developed countries. To this end, the two types of saving regressions are estimated: one based on an annual panel of OECD countries and the other using Polish quarterly time series. Compared to an ?average? OECD country, the Polish private and household saving rates are more affected by the process of financial deepening. Moreover, they are also more sensitive to changes in government and corporate savings.
