Trade and growth in the New Member States. The role of global value chains (Przeczytaj streszczenie | Read abstract)
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 roughly 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.

Up or Down the Value Chain? A Comparative Analysis of the GVC Position of the Economies of the New EU Member States (Przeczytaj streszczenie | Read abstract)
The pattern of trade of the Central and Eastern European countries has been changing since the beginning of the economic transition in the early 1990s. By the end of the century this process was additionally strengthened by their integration with the European Union and overlapped with the development of global value chains (GVC) spanning across Europe with which the new member states (NMS) have become increasingly integrated.
In this paper, we shed light on these changes by analysing the position of the NMS within the global value chains. We employ the upstreamness measure proposed by Antràs et al. (2012) and use the World Input–Output Database. Although we observe a global increasing trend in the upstreamness of all countries, we find that the NMS have in many cases gone against this trend while converging in their production structure within their group and with the EU-15. This convergence is mostly observed in Czech Republic, Hungary, Poland and Slovakia where the level of upstreamness in the most important exporting sectors was close to that of Germany by the end of the analyzed period 1995–2011.

Analyzing the effciency of the pension reform: the role for the welfare effects of fiscal closures (Przeczytaj streszczenie | Read abstract)
Pension system reforms involve fiscal consequences. In practice, a variety of fiscal closures may be implemented, while not all of them involve the same extent of distortions. This paper develops an overlapping generations model to analyze the case of a shift from pay-as-you-go defined benefit system to a partly funded defined contribution system. We calibrate the system to mimic the economy of Poland, which actually implemented such reform in 1999. We analyze the efficiency of the reform with two main closure types: public debt and taxes. Regardless of the fiscal closure scenario this particular reform seems to be efficient in terms of welfare and enhances economic performance. Comparing the welfare of various closures we find that while labor taxation yields relatively higher welfare gain, public debt closure involves least need for the redistribution if capital pillar is to be implemented.
Unprivatizing the Pension System: The Case of Poland (Przeczytaj streszczenie | Read abstract)
In many countries, the fiscal tension associated with the global financial crisis brings about the discussion about unprivatizing the social security system. This article employs an Overlapping Generations model to assess ex ante the effects of such changes to the pension reform in Poland from 1999 as implemented in 2011 and in 2013. We simulate the behaviour of the economy without the implemented/proposed changes and compare it to a status quo defined by the reform from 1999. We find that the changes implemented in 2011 and in 2013 are detrimental to welfare. The effects on capital and output are small and depend on the selected fiscal closure. Implied effective replacement rates are lower. These findings are robust to time inconsistency. The shortsightedness of the governments imposes welfare costs.
Decreasing Fertility vs Increasing Longevity: Raising the Retirement Age in the Context of Ageing Processes (Przeczytaj streszczenie | Read abstract)
Given the decreasing fertility and increasing longevity, in many countries the policy debate emphasizes the role of either raising the minimum eligible retirement age (MERA) or raising fertility to avoid adverse changes in the population structure. In this paper we evaluate the welfare and macroeconomic effects of increasing the retirement age for various demographic scenarios under three major pension systems (defined benefit, notionally defined contribution and funded defined contribution). We compare populations with decreasing fertility, increasing longevity and one subject to both of these changes, and show that the welfare effects of raising MERA stem mainly from longevity. We show that – for increasing longevity – raising the retirement age is universally welfare enhancing for all living and future cohorts, regardless of the pension system and fertility. Finally, we show scope for further welfare gains if productivity is relatively high at old ages.
Small assumptions (can) have a large bearing: evaluating pension system reforms with OLG models (Przeczytaj streszczenie | Read abstract)
The objective of this paper is to inquire the consequences of some simplifying assumptions typically made in the overlapping generations (OLG) models of pension systems and pension system reforms. This literature is largely driven by policy motivations. Consequently, the majority of the papers is extremely detailed in the dimension under scrutiny. On the other hand, complexity of general equilibrium OLG modeling necessitates some simplifications in the model. We run a series of experiments in which the same reform in the same economy is modeled with six different sets of assumptions concerning the shape of the utility function, time inconsistency, bequests? redistribution, labor supply decisions and internalizing the linkage between social security contributions and benefits in these decisions as well as public spending. We find that these assumptions significantly affect both the size and the sign of the macroeconomic and welfare measures of policy effects with the order of magnitude comparable to the reform itself.

Productivity spillovers in the GVC. The case of Poland and the New EU Member States (Przeczytaj streszczenie | Read abstract)
The New 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, ie. 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. In Poland the productivity gains for domestic firms are located in production of intermediate goods with high foreign value content as well as in goods located close to the final demand. In many other NMS the benefits are concentrated close to the final demand.
