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.

WP215. Exports and growth in the New Member States. The role of global value chains

We analyze the determinants of value added and productivity growth of New Member States in the period between 1995 and 2009. We show that in the analyzed countries exports contributed to between 30 to over 40% of the overall growth of GDP while the contribution of the domestic component varied from negative to over 60%. We show that in the most important export manufacturing industries of the NMS, the growth in exported value added was substantial, while the growth of the domestic component of GDP was mostly due to the growth in services. We associate growth of sectoral productivity with the foreign direct investment and exporting but, more importantly, with the position of a sector/country in the global value chains. We show that sectors that have imported intermediate goods have experienced higher productivity growth. Moreover, productivity growth was found in sectors further away from the final demand and in sectors exporting intermediate goods.

WP190. Productivity spillovers in the GVC. The case of Poland and the New EU Member States

The new EU member states have been experiencing firm internationalization not only through inward foreign direct investment but also through exporting, importation of foreign technology in investment goods and increased use of imported intermediates. We argue that there are important productivity spillovers within the global value chains, i.e. FDI alone does not tell the whole story of the reallocation processes going on in the economies of the NMS. We augment the standard TFP spillover empirical model with modern measures of GVC participation. We show that increased foreign content of exports brings additional productivity gains on top of the ones attributed to exporting. Moreover, we show that in selected cases, participation in the GVC leads to a smaller productivity gap between foreign and domestic firms.

WP146. Teaming up or writing alone - authorship strategies in leading Polish economic journals

The returns to scientific collaboration have been widely acknowledged. The general trend observed in top scientific journals is an increase in collaborative activities both between researchers and between institutions, especially with regard to international co-authorship. Not only there is a growing number of papers written in co-authorship, but also there is an increase in the number of co-authors. In this paper, we investigate whether similar tendencies have emerged in the scientific community of economists in Poland. Using social network analysis, we focus on collaboration between researchers publishing in five leading Polish economic journals. We find that both the number of articles written in collaboration and average number of authors per article are steadily increasing. Yet, compared to what we observe in western economic journals, the scale of collaboration is modest. Furthermore, the increase in collaborative activity which we observe is not followed by a rise in collaboration with foreign co-authors.

WP112. Age-productivity patterns in talent occupations for men and women: a decomposition

One could expect that in the so-called talent occupations, while access to these professions may differ between men and women, gender wage gap should be actually smaller due to high relevance of human capital quality. Wage regressions typically suggest an inverted U-shaped age-productivity pattern. However, such analyses confuse age, cohort and year effects. Deaton (1997) decomposition allows to disentangle these effects. We apply this method to inquire the age-productivity pattern for the so-called "talent" occupations. Using data from a transition economy (Poland) we find that indeed talent occupations have a steeper age-productivity pattern. However, gender differences are larger for talent occupations than for general occupations.

WP37. Crises and Joint Employment-Productivity Dynamics: A Comparative Perspective for European Countries

The aim of the paper is to investigate the short-term joint dynamics of productivity and employment during the economic down cycles in the EU economies over the past 20 years. Disentangling the shift in labour demand into a change of employment-productivity schedule and a movement along it, we focus on the last 2-3 crises, highlighting the peculiarities of the last recession. Namely, we demonstrate that many of the EU countries - unlike the United States - do not follow the RBC pattern. We also suggest some possible institutional fundamentals that could explain this phenomenon.

WP22. Access to Credit, Factor Allocation and Farm Productivity: Evidence From the CEE Transition Economies

This paper analyses how farm access to credit affects farm input allocation and farm efficiency in the CEE transition countries. Drawing on a unique farm level panel data with 37,409 observations and employing a matching estimator we are able to control for the key source of endogeneity - unoberserved heterogeneity. We find that farms are credit constrained both in the short-run as well as in the long-run, but that credit constraint is asymmetric between inputs. Our estimates suggest that farm access to credit increases TFP up to 1.9% per 1000 EUR of additional credit. The use of variable inputs and capital investment increases up to 2.3% and 29%, respectively, per 1000 EUR of additional credit. Due to credit-financed investment in labour-saving farm equipment, labour use reduces for low level of credit. Farms are found not to be credit constrained with respect to land.
