Artykuł koncentruje się na ocenie umiejętności zarządzających portfelami inwestycyjnymi polskich funduszy akcyjnych. W badaniu wykorzystano stosunkowo dużą próbę badawczą, liczącą 87 podmiotów. Horyzont czasowy badania ustalono na okres 2000- -2015. Wyniki menedżerów oceniane były pod kątem umiejętności doboru walorów oraz wyczucia rynku. Otrzymane rezultaty wskazują na brak umiejętności w przewidywaniu tendencji rynkowych, mierzonych parametrami z modeli Treynora–Mazuya oraz Henrikssona–Mertona. Analiza z wykorzystaniem testu istotności dla wartości średniej, liczebności dodatnich i ujemnych wyników, jak również metod panelowych dla danych przestrzenno-czasowych nie dała jednoznacznych rezultatów co do istnienia umiejętności selekcji.

This paper focuses on evaluating the skills of portfolio managers of Polish equity funds. A relatively large study sample, i.e. 87 entities, is used. The time horizon is the period 2000-2015. The returns are analyzed from the angle of stock selection and market timing ability. The obtained results show the lack of market timing skills measured with the parameters of Treynor–Mazuy and Henriksson–Merton models. The one sample t-test and frequency analysis of the positive and negative performance as well as the panel methods for the TSCS data are unequivocal in relation to the existence of stock selection skills.

In the world pervaded with moral crises, unethical practices not only in the private and public sector but also in various charity organisations and cultural institutions, where one faces a loss of values and authorities, a question arises about the reasons for such occurrences. Simultaneously the need for developing tools helping to diminish the effects of unethical undertakings and eventually prevent them from emerging at all, comes into being. The main purpose of the presented paper is to convince that introducing ethics, social responsibility, and anti-corruption policies in higher education programmes accounts for a significant and undoubted tool that may bring positive results for both individuals and societies in the future. Such programmes will develop managerial competences that will play an even more important role than hard skills and acquired knowledge. The authoresses support the thesis with an example of a good practice based on a case study of a programme introduced at one of the Polish universities educating future managers for public administration. In the conclusions the authoresses will underline the necessity of educating responsible, conscious, and ethical managers especially for public sector institutions as well as they will suggest the paths for further research in this area.
