Pomimo istnienia w literaturze ewidentnego konsensusu, że prywatyzacja jednoznacznie prowadzi do wzrostu produktywności i zyskowności przedsiębiorstw, problem obciążenia estymatorów wywołany endogenicznością jest znaczny, co potwierdzają liczne metaanalizy. W artykule zaproponowano nową metodę rozwiązującą problem endogeniczności, którą stosuje się do danych o uniwersum polskich średnich i dużych przedsiębiorstw w latach 1995–2008. Rezultaty estymacji wskazują, że wywołana prywatyzacją poprawa wyników przedsiębiorstw widoczna jest jedynie w niektórych ich grupach.

Despite an apparent consensus in the literature that privatisation universally leads to an increase in firm performance, the problem of endogeneity bias is profound and has been emphasised in a number of meta-analyses. We propose a new instrument to address the endogeneity bias and apply it to Polish medium-sized and large firms in the period of 1995 to 2008. We find that improvements in firm performance are not universal; in particular, we find no improvement among manufacturing firms privatised to domestic investors.

The paper examines the effects of a multilateral reduction of customs duties on non-agricultural goods, under a “nonlinear Swiss formula,” on Poland’s foreign trade, including both exports and imports. As part of the Doha Development Round of the World Trade Organization (WTO), countries are trying to work out a mathematical formula according to which national customs tariffs would be reduced. This is the key focus of ongoing negotiations concerning Non-Agricultural Market Access (NAMA). The author analyzes the newest version of the Global Trade Analysis Project (GTAP), known as GTAP 6.0, according to four scenarios. The GTAP model is a multiregional, multi-sector model that is often used to study the effects of commercial policy. The author describes the results of the multilateral negotiations according to their state as of the end of August 2006. The scenarios analyzed by the author differ in terms of “reduction coefficient A” under the Swiss formula. However, in all variants, the coefficient for developed countries is lower than that for developing countries. The analysis shows that the reduction of customs duties will have a limited impact on Poland’s foreign trade. All scenarios point to a small increase in the volume of exports and an insignificant drop in the volume of imports, accompanied by a rise in import prices and a decline of export prices. The deterioration of the country’s terms of trade is the most visible in the most radical scenario. The European Union as a whole would be more visibly affected than Poland by the planned reduction of customs duties. Similarly, the move would lead to limited changes in the overall volume of industrial production in Poland, though, in terms of individual sectors, there will probably be a clear drop in the production of clothing, textiles and leather goods, accompanied by a small increase in output in the wood industry. Changes in the volume of trade, production and employment are the most visible in the radical scenario. In all options, the reduction of customs duties will have no perceptible influence on Poland’s gross domestic product, though GDP in purchasing power parity terms will decrease as a result of deteriorated terms of trade. There will be a marginal deterioration in the overall level of prosperity in Polish society. This will be due to the fact that the drop in terms of trade will outweigh the increase of consumer surplus.

EU enlargements have given new EU member states access to the European Single Market. While tariff liberalisation was already completed at the time of enlargement, technical regulations were subject to different sectoral approaches, including harmonisation and mutual recognition. We employ a structural gravity model estimated using sectoral trade data from 1987 to 2020 to assess the trade effects of these measures. We find that trade expansion, particularly exports of the NMS to the incumbent EU members, has been stronger in the sectors covered either by the Old Approach (full harmonisation) or the New Approach (essential requirements) than in sectors covered by mutual recognition. The New Approach has been more effective when coupled with mutual recognition at the sector level than with either approach alone. Our results imply that the TBT harmonisation has had a heterogenous impact on different sectors (the most important for low-tech industries was the Old Approach, while for high-tech, it was the New Approach).

The paper analyses the economic implications of the accession of New Member States (NMS) to the European Union (EU) in 2004 and 2007. The estimation effects of integration with the EU were carried out as a comparative case study using the synthetic control method (SCM) proposed by Abadie and Gardeazabal. Compared to previous studies analysing the effects of accession to the EU (Campos, Coricelli and Moretti), we check for the importance of the quality of economic institutions for the matching process of the analysed economies with their comparators. The results of the econometric analysis show a positive impact on the country performance 6 years and 12 years after accession to the EU. The gains from accession are large but not universal. For 5 of the 10 analysed countries the difference in levels of per capita gross domestic product (GDP) against the counterfactual is at least 30%.

The study aims to either validate or disprove the hypothesis that market services, alongside industry, played a key role in spurring the development of the Polish economy in 1995-2012. The authors conduct a multifaceted empirical analysis that addresses a range of research questions related to the role of structural change and variations in relative prices in economic growth. The article also examines the behavior of industry and services during a business cycle and the internal differentiation of market services. The results of the authors’ macroeconomic analyses are based on national accounts data from 1995-2012. The article scrutinizes differences across service sectors in terms of the levels and dynamics of labor productivity and employment, based on firm-level data from 2005-2012. The authors find that the role of market services in employment in Poland steadily increased in 1995-2012. At the same time, due to technological change, industry enjoyed stronger growth in labor productivity and total factor productivity (TFP). The prices of manufactured goods steadily fell compared with services. However, the cyclical variability of employment and value added was clearly lower in market services. Due to substantial heterogeneity across firms within the considered categories, the authors say they were “unable to identify significantly higher dynamics of exports-intensive, capital-intensive, business-to-business (B2B) or knowledge-based services.” On the basis of their research, the authors predict that, due to the increasing role of market services, Poland’s economic growth will be slower but more stable in the future.

Celem artykułu jest weryfikacja hipotezy, że usługi rynkowe odgrywały, obok przemysłu, kluczową rolę w procesach rozwojowych gospodarki Polski w latach 1995-2012. Cel ten zrealizowano poprzez uszczegółowioną, wielowątkową analizę empiryczną, pozwalającą odpowiedzieć na pytania badawcze związane z rolą obserwowanej w Polsce zmiany strukturalnej oraz zmian cen względnych w objaśnianiu dynamiki wzrostu gospodarczego, a także zachowaniem przemysłu i usług w cyklu koniunkturalnym oraz zróżnicowaniem wewnętrznym usług rynkowych. Wyniki analiz makroekonomicznych oparto na danych z rachunków narodowych z lat 1995–2012. Ponadto opierając się na danych jednostkowych na poziomie firm z lat 2005–2012, przeanalizowano różnice pomiędzy poszczególnymi branżami usługowymi pod względem poziomu oraz dynamiki produktywności pracy i zatrudnienia. Uzyskane wyniki są następujące. W latach 1995–2012 obserwowano w Polsce systematyczny wzrost udziału usług rynkowych w zatrudnieniu. Równocześnie jednak produktywność pracy oraz całkowita produktywność czynników (TFP) rosły wolniej w tym sektorze w porównaniu z sektorem przemysłowym, w związku z relatywnie szybszym postępem technologicznym w przemyśle. Systematycznie spadała też cena względna dóbr przemysłowych w porównaniu z usługami. Zmienność zatrudnienia i wartości dodanej w cyklu koniunkturalnym była natomiast wyraźnie mniejsza w usługach rynkowych. Na tle wysokiej heterogeniczności firm w ramach poszczególnych branż, nie stwierdzono istotnie różnej dynamiki rozwojowej usług eksportointensywnych, relatywnie kapitałochłonnych, skierowanych do biznesu (B2B), ani usług opartych na wiedzy. Z uzyskanych wyników wyprowadzono prognozę, że gospodarka polska będzie w przyszłości wskutek zwiększającej się roli usług rynkowych rosnąć nieco wolniej, ale stabilniej niż dotychczas.
