Tests of Normality of Functional Data

The paper is concerned with testing normality in samples of curves and error curves estimated from functional regression models. We propose a general paradigm based on the application of multivariate normality tests to vectors of functional principal components scores. We examine finite sample performance of a number of such tests and select the best performing tests. We apply them to several extensively used functional data sets and determine which can be treated as normal, possibly after a suitable transformation. We also offer practical guidance on software implementations of all tests we study and develop large sample justification for tests based on sample skewness and kurtosis of functional principal component scores.     

Heterogeneous determinants of local unemployment in Poland

We identify determinants of large disparities in local unemployment rates across Poland. Using an extensive panel data-set on the NUTS-4 level (i.e. the poviats level, or districts or counties level) we examine a wide range of determinants of local unemployment. Our research examines two groups of the determinants: one related to equilibrium theory and the other related to disequilibrium theory of local unemployment. We find that demographics, education and sectoral employment composition exert a stronger impact over rates of local unemployment than various demand factors. The impact of the determinants, while robust for outliers, is not homogeneous across Polish regions. In particular, in the most depressed local labour markets, skill improvement programmes do not appear to work and unemployment rates are relatively less responsive to investment. Our research suggests that there is no easy cure for local unemployment in Poland, but a few policies have the potential to slightly reduce existing disparities.     

POLONIA dynamics during the years 2006–2012 and the effectiveness of the monetary Policy of the National Bank of Poland

In the study we investigate the effectiveness of the National Bank of Poland in counteracting the negative results of the financial crisis in the Polish interbank market. The situation was exceptional in a sense, that during the period of the financial crisis the Polish interbank market experienced liquidity surplus, and the main problem of the central bank was to regain confidence among commercial banks and stimulate interbank transactions. We concentrate on the spread between the rate of overnight interbank loans and the reference rate and based upon its dynamics we assess the monetary policy of the Polish central bank. Using econometric techniques we study how the central bank influenced the spread, when its control over it weakened and when was it strengthened. The study is supported by the results of the survey directed to the headquarters of commercial banks. We conclude that the ability of the central bank to control overnight rate was temporarily lost during the first phases of the financial crisis, but gradually regained after implementation of the confidence pact.     

Educational upgrading,structural change and the task composition of jobs in Europe

We analyze the changes in the task content of jobs in 24 European countries between 1998 and 2015. We link the O*NET occupational data with the European Union Labour Force Survey (EU‐LFS), and use the methodology of Acemoglu and Autor ( 2011 ). We find that the intensity of non‐routine cognitive tasks grew in all countries, while the intensity of manual tasks declined. Workforce upskilling was the major factor contributing to these developments. The intensity of routine cognitive tasks grew in most Central and Eastern European countries, but it declined in Western European countries. This difference is attributed to the contrasting patterns of structural changes in these groups of countries.     

Corporate social responsibility and employee attitudes: evidence from a study of Polish hotel employees

This study, based on data collected from low-ranking employees working in Polish hotels, tests a research model that investigates whether there are links between corporate social responsibility (CSR), operationalized as “self-related” CSR experiences and “others-related” CSR experiences, and job satisfaction and organizational commitment, and between both attitudes and work engagement. Structural equation modelling was used to assess these relationships, using a 20 point questionnaire answered by 412 respondents. The results indicate that “others-related” CSR experiences are positively associated with satisfaction and commitment, while “self-related” CSR experiences with the latter variable. Likewise, organizational commitment, unlike job satisfaction, was linked to work engagement. However, contrary to our a priori assumptions and prior research, it turned out that job satisfaction was not a predictor of commitment. The paper discusses theoretical and practical implications of the findings. The study's most important practical implication is that Polish hotel employees attach weight to responsible behaviour: the hotel industry should perceive CSR in terms of strategic significance. Companies that want a committed and engaged workforce – and, by extension, to enhance their competitiveness – should embrace CSR. The paper concludes by highlighting its limitations and suggesting future research avenues.     

International hotel chains and environmental protection: an analysis of Hilton's we care! programme (Europe, 2006–2008)

Using the case study method, this paper evaluates and analyses Hilton's we care! programme for improving the environmental performance of the 70 Hilton Worldwide hotels in operation in Continental Europe in 2006–2008. It explores the practical dimension of “greening” hotel operations in the context of corporate social responsibility (CSR), and demonstrates the close links between CSR and human resource management (HRM) in hotels. It deepens the understanding of corporate environmentalism and seeks to disseminate best practice among hospitality managers. The programme's distinctive and innovative character as well as its weaknesses and strengths are highlighted. Barriers to behavioural change in hotel operation are discussed. The programme involved over 16,000 employees, created hotel-specific action teams linking all employee levels and reduced energy use per square metre by 15%, water use and CO₂ emissions per guest night by 8% each over three years. Avoided utility costs totalled US$16 million, of which US$9.6 million can be attributed to changes in human behaviour. The paper makes a case for a holistic approach that combines the introduction of IT-based measurement and performance-assessing tools with genuine employee empowerment and green awareness raising. The study concludes with future managerial policy recommendations that simultaneously bear upon corporate environmentalism and HRM.     

Grading Innovation in an International Marketing Course: Promoting Student Collaboration and Individual Accountability

In this article, the author proposes an innovative, exam-based homework grading method to facilitate both collaboration among students and individual accountability while learning a complex theory and applying it to solve a problem. Results from this novel approach to grading a comparative advantage theory homework assignment, using an objective exam performance measure to adjust original homework grades, show that students increase their comprehension of the frequently misunderstood theory. This novel grading method can be applied in a variety of contexts to promote student collaboration in preparation of academic work while providing incentives to encourage individual accountability and engagement.     

On market mavens and consumer self‐confidence: A cross‐cultural study

Market mavens are attentive to media and important diffusers of marketplace information. This study examines the relationships between cultural individualism, general and consumer self‐confidence, and market mavenism in the context of two distinct cultural systems, the United States and South Korea. The examination of cross‐cultural equivalence of the constructs under study provides evidence for both configural and full or partial metric invariance. The results indicate that cultural individualism is positively related to general self‐confidence, general self‐confidence is positively related to consumer selfconfidence, and consumer self‐confidence is positively related to market mavenism. Additionally, this research shows that these relationships hold in both the U.S. and South Korean samples. The results of this study indicate that market mavenism, and thus levels of confidence about marketplace knowledge and speed of diffusion of such information may be more prevalent among the more individualistic than collectivistic consumers. © 2007 Wiley Periodicals, Inc.     

EMPLOYMENT PROTECTION LEGISLATION AND THE GROWTH OF THE SERVICE SECTOR IN THE EUROPEAN UNION

In modern developed economies it is the service sector that generates jobs. In Anglo-Saxon economies, where employment protection legislation is low and unions comparatively weak, services account for three-quarters of income and four-fifths of jobs. Yet in France, Germany and Italy, where the reverse is true, the service sector accounts for much less of the economy in terms of income and jobs. This article shows that employment protection legislation – defended by trade unions still dominating manufacturing in continental Europe – results in higher unemployment rates and also negatively affects the growth of services.
