The article presents an efficiency evaluation for teaching and research in Polish institutions of higher education. Thirty one public universities in Poland were studied using the nonparametric DEA method from 2001 to 2008. Teaching outcomes were evaluated by the numbers of full-time and part-time graduates, while research activities were assessed by number of publications, citations and value of research grants. The scores for teaching and research efficiency were negatively correlated, which could indicate a trade-off between teaching and research activities.

W artykule przedstawiono analizę ilościową oceny efektywności procesu kształcenia i prowadzonych badań naukowych w szkołach wyższych. Analizie poddano 31 publicznych uczelni MNiSW w latach 2001–2008. Pomiar efektywności został przeprowadzony przy zastosowaniu metody nieparametrycznej DEA oddzielnie dla dwóch podgrup uczelni: uniwersytetów i szkół technicznych. Za rezultaty procesu kształcenia przyjęto liczbę absolwentów studiów stacjonarnych oraz studiów niestacjonarnych, a za wyniki działalności badawczej uczelni: liczbę publikacji, cytowań oraz wartość grantów. Porównanie wskaźników efektywności wskazuje na ich ujemną korelację, co może potwierdzać wymienność działalności dydaktycznej i naukowej.

We propose an empirical analysis of testing the relationship between gender wage gap and economic growth. The study takes into account 12 manufacturing sectors in 18 OECD countries for the period between 1970 and 2005.We use industrial statistics (EU KLEMS, 2008) on female and male wages that distinguish between wages paid to different groups of workers classified according to skill level: high, medium and low. We estimate augmented production function where the male-female wage differentials constitute a potential channel influencing growth (posi-tively or negatively). Our research is motivated by the ambiguous results of previous empirical studies (e.g.: Seguiono 2000; Busse, Spielmann 2006; Seguino 2011; Schober, Winter-Ebmer 2011). Our main findings indicate that gender wage gap for high, medium and low-skilled workers is negatively correlated with sectoral growth. This results are confirmed in a number of robustness checks.

W artykule przeprowadzono analizę empiryczną efektywności szkół wyższych wraz z estymacją determinujących ją czynników. Próba badawcza składa się z uczelni z 19 krajów europejskich i obejmuje dane dla lat 2011–2014. Na podstawie nieparametrycznej metody DEA oszacowano wskaźniki efektywności, gdzie za nakłady przyjęto: wartość przychodów i liczbę nauczycieli akademickich. W wynikach działalności uczelni ujęto liczbę absolwentów oraz liczbę publikacji. Dodatkowo zbadano relację pomiędzy wybranymi zmiennymi a wskaźnikami efektywności. Rezultaty wskazują, że uczelnie większe i starsze są bardziej efektywne. Porównanie uczelni o tej samej wielkości i roku założenia pokazało, że te z nich, które mają większy odsetek pracowników niebędących nauczycielami akademickim i niższy udział przychodów zewnętrznych w budżecie, charakteryzują się niższą efektywnością.

Wywiad dotyczy wyzwań związanych z tworzeniem publicznie dostępnej i zharmonizowanej bazy obejmującej dane na temat poszczególnych instytucji szkolnictwa wyższego z krajów europejskich: European Tertiary Education Register (ETER) oraz możliwości wykorzystania jej do porównań międzynarodowych. Benedetto Lepori przekonuje w nim, że ogólny dostęp do danych na poziomie indywidualnych uczelni powinien być czymś normalnym. Dodatkowo uważa, że wykorzystywanie podejścia nakłady-wyniki wraz z zaawansowanymi narzędziami badawczymi w zakresie oceny efektywności i produktywności jest zasadne z punktu widzenia stawianych pytań badawczych, jednak nie powinno się ich automatycznie stosować np. do ewaluacji uniwersytetów czy dystrybucji środków finansowych.

This study examines the linkages between GVC involvement and wages in Poland given different wage bargaining schemes. The analysis is based on microdata from the European Structure of Earnings Survey for Poland combined with sectoral data from the World Input-Output Database. In particular, two measures of GVC involvement were used: the share of foreign value added (FVA) to export and the measure of traditional offshoring. The institutional settings are represented by the wage bargaining scheme which reflects the level at which the collective pay is agreed. The results show that despite the lack of a significant relationship between the sectoral involvement in GVC and the level of wages in Poland, on average workers covered by the collective pay agreement receive higher wages. Moreover, the wage-GVC nexus is conditioned on the type of pay agreements: the positive wage effect from national agreements is eliminated for a certain range of GVC intensity.

Tematem artykułu jest zbadanie powiązań między globalnymi procesami fragmentacji produkcji (GVC), rutynizacją pracy a dobrostanem pracowników w Polsce. W szczególności skupiono się na wybranych miernikach warunków pracy, takich jak otoczenie społeczne, intensywność pracy i jakość czasu pracy, w celu zbadania ich zależności od zaangażowania w handel międzynarodowy i rutynizacji. Połączone zostały indywidualne dane opisujące warunki pracy i dobrostan pracowników z danymi sektorowymi zawierającymi informacje o zaangażowaniu w globalne procesy produkcyjne. Wyniki wskazują na umiarkowany związek pomiędzy warunkami pracy a zaangażowaniem w GVC wśród polskich pracowników. W sektorach bardziej zależnych od GVC pracownicy otrzymują średnio niższe wynagrodzenie. Ponadto, związek między GVC a innymi aspektami warunków pracy jest statystycznie istotny, jednakże w ujęciu ekonomicznym ma wymiar marginalny. Podobnie rutynizacja pracy jest ujemnie skorelowana z wynagrodzeniami i warunkami pracy (z wyjątkiem wskaźnika intensywności pracy). Najważniejszą zaletą przeprowadzonego badania jest wielowymiarowe podejście do analizy warunków pracy, co znacznie poszerza dotychczasowy stan wiedzy.

The paper aims to explore the linkages between global production fragmentation, routinisation and the well-being of workers in Poland. In particular, the focus is placed on the selected measures of working conditions, such as the social environment, work intensity, and working time quality to examine their dependence on involvement in international trade and the routinisation level. We merge individual data describing the working conditions and well-being of workers with sector-level data containing information on involvement in global production processes and occupational data on the job routinisation level. The findings reveal a moderate association between working conditions and global value chain (GVC) involvement among Polish workers. In more GVC-dependent sectors, workers receive lower remuneration on average. The relationship between GVC and other working conditions is significant, but the economic significance is marginal. Similarly, the routinisation of work is negatively correlated with wages and working conditions (except work intensity). The main contribution of this study is its multidimensional approach to analysing working conditions, which significantly expands existing evidence in the literature.

This paper investigates opinion contagion in collective behaviour using threshold model (Granovetter (1978)). The theoretical background is the spiral of silence concept developed by Noelle-Neumann (1974), arguing that people only assert their opinions if they perceive a minimal support from a relevant proportion of others. We apply the model to explain the dispersion between pre-elections preferences and the final results of the Polish parliamentary and presidential elections in 2005. It is shown that the minority opinions were more widely-held than was declared in opinion polls as a consequence of different distributions of the threshold values of opinion assertion.

This paper examines the gender wage gap in Polish public higher education institutions. The analysis is based on the unique web-survey data in which information about level of the salary and characteristics of the employees has been gathered. The study involves wage regression analyses in which among additional employed covariates have been: gender, experience, academic rank, type of the institution (e.g university versus economic school) and productivity. The productivity is measured in terms of the publication record. Results of the study confirm that on average women earn less than men, but this is mostly due to the differences in academic ranks, and not a consequence of wage discrimination per se. Additionally, it was shown that the variable related to productivity is not among the important determinants of one's salary. This lack of relationship between research productivity and individual academics' salaries questions the way research is assessed, and can be considered demotivating in terms of careers in Polish academia.

Research background: China is regarded as the ?world factor? highly involved in international trade and plays an increasingly important role in the global value chains (GVC). Additionally, the ?One-Belt One-Road? (OBOR) initiative was proposed by the Chinese government to further promote China in the international market. Purpose of the article: The article explores the role of the OBOR in China?s exports and global value chain. It aims at: 1) verifying how OBOR impacts the volume of China's export and value-added export to its partners. 2) checking whether or not OBOR strengthens the industrial connection between China and its participants at the GVC level. 3) examining the different roles of corridors in China's exports and GVC. Methods: The empirical analysis is based on the augmented gravity model of international trade, which comprises China and its 197 partners in the period 2000?2018. The model is estimated for gross export as well GVC measured by domestic value added in export and the value contributed by a partner to China?s exports. Findings & value added: In general, there is a significant positive correlation between OBOR and the volumes of China?s export, domestic value-added trade and the value of partner?s contributed in China?s export. However, some of the results are blurred by OLS and FE methods. The author points out that FE-PPML estimation methods are more adequate. Among the six economic corridors, Bangladesh-China-India-Myanmar (BCIM), China-Pakistan (CP) and China Indochina Peninsula (CIP) were proven to play a prominent role in promoting China?s export, DVA and strengthening the links of global value chains. It is worth noting that the China-Mongolia-Russian Federation (CMRF) corridor harms China's export and DVA trade, and at the same time promotes countries in its region that benefit from trade with China.

Research background: Wage inequalities are still part of an interesting policy-oriented research area. Given the developments in international trade models (heterogeneity of firms) and increasing availability of micro-level data, more and more attention is paid to wage differences observed within and be-tween firms. Purpose of the article: The aim of the paper is to address the research gap concerning limited cross-country evidence on a nexus of wage inequality?global value chains (GVCs), analysed from the perspective of wage inequality components within and between firms. Methods: This paper uses a large employee?employer database derived from the European Structure of Earnings Survey (SES), combined with sector-level indicators of GVC involvement based on the World Input-Output Database (WIOD). As a result, a rich database covering more than 7.5 million observations is created. The regression-based decomposition modelling technique developed by Fiorio and Jenkins (2010) is used to identify the contributions of different factors to wage inequalities, focusing on the components within and between firms. Findings & value added: The analysis presented in this paper aimed to show the contribution of GVC involvement, among various other factors, to the observed inequality of wages. Due to the use of a rich database that merges employer and employee data, the effects materialised with respect to different types of wages could be analysed separately, in particular components between and within firms. The general conclusion from the regression-based decomposition in log wages is that GVCs contribute marginally to the observed wage inequality in the European sample analysed in this paper. Some differences confronting the components within and between firms (the latter dominates) are observed; there is also certain intra sample heterogeneity in the estimated results (e.g. due to sector type or country group), but the general result is robust.

The paper presents a comprehensive reform agenda for Polish universities in the years to come. It discusses major problems of higher education funding, governance and organization and suggests a set of possible interrelated steps. The reform agenda is based on several underlying principles, including competition and quasi-market, internationalization, scientific excellence, vertical stratification of the system (into three major institutional types – with a focus on the emergence of internationally visible national flagship universities), and the concentration of research funding in research-active universities. The paper refers also to the national parameterization exercise (as performed by the KEJN), major national funding bodies, national quality assurance and accreditation systems, as well as academic careers.
