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: z`f9DAcd$i#te-B1*bH{]Jm.PZY]#[rPY!*+KUbZkgYH6zjk=sf+R~YKF

Prosimy przesyłać dwa pliki:

WP210. Public-private wage differential in a post-transition economy: A copula approach to the switching regression model

In this study, we estimate the public sector wage premium in a post-transition economy, a quarter of a century since the collapse of the old regime. Our methodology uses a copula method to estimate the switching regression model, which allows for the relaxation of the restrictive assumption of joint normality. We control for employment selection into both sectors using an instrument based on information regarding learned professions. We use data from the Polish Survey of Earnings by Occupations (2012). Contrary to earlier results for Poland, we found positive selection into employment in both sectors, with positive ATET and negative ATEU. The results suggest that both private and public sector employees select themselves into the sector in which they earn more than they would in a counterfactual scenario.

WP207. Return to vocational education. Evidence from Poland

Vocational education in upper-secondary school has been perceived for many years as being inferior to general education, in spite of the fact that vocational education graduates enjoy a faster transition from school to work and are more likely to have a permanent first job. As a consequence of the reform of the educational system that took place in Poland in 1999, the enrolment ratio in vocational schools has fallen dramatically. The empirical evidence in the literature on the returns to vocational education is limited. This study fills that gap and looks into wage premium for workers with vocational education in Poland before and after the reform of the educational system. The relative returns to different types and levels of education were estimated using a standard Mincerian wage equation
framework. The empirical analysis concentrated on a comparison of the relative benefits of vocational and nonvocational education. The results showed that vocational education graduates have, on average, a higher probability of finding a permanent job, and secondary-vocational education graduates receive higher earnings than secondary general education graduates in Poland. However, wages of vocational education graduates are lower than those of secondary general education. In spite of this, the decreasing number of vocational education graduates post-reform has contributed to reducing this gap.

WP204. Evolution of the public-sector wage premium in Poland

The aim of this paper is to estimate the adjusted sectoral wage gap in Poland in the period 1999–2012. We use a set of individual data from the survey on the structure of earnings by occupations (SEO) carried out by Central Statistical Office in Poland (CSO) every two years for entities with more than nine employees. We apply quantile regression and the Ñopo decomposition method to address several methodological problems of wage differential analysis. We show that, after controlling for structural differences in employment, there is no clear trend in the evolution of the adjusted public-sector wage premium in Poland in recent years. The parametric approach indicates a positive and growing premium, with significant variations across different parts of wage distribution. The non-parametric approach yields different results, indicating a negative premium with no clear trend in the period 1999–2012, with a declining public-sector wage penalty in recent years.

WP44. Demand linkages and spatial agglomeration of Indian states

In this paper, we examine the spatial relationship between wages and consumer purchasing power across Indian states to see whether regional demand linkages contribute to spatial agglomeration. We estimate a variety of the market-potential functions derived from the Harris model as well as more recent models of the New Economic Geography. Besides market-potential, we consider housing stock, density of roadways, density of telecom, and dummies to capture cyclical fluctuations as parameters of consumer purchasing power and demand to explore the importance of scale economies and transport costs. The estimation results suggest that all the above factors influence demand linkages between states, which are strong and growing over the period from 1999-2000 to 2007-2008.
