Streszczenie:
The main issue discussed in the article is the moral aspect of
economic activity. The article presents major ethical systems
and the problem of different moral judgements in practice.
Each human act can be either ethical, unethical or ethically
neutral. Moral evaluation of an act and moral responsibility
of a person must be distinguished. Ethical systems presented
in the article are complemented by examples from economic
activity. The frames suggested by the author can be employed
in research of ethical and unethical behaviour in economic life
while taking into account different moral systems. However, in
order to carry out successful research in this area, it is necessary
to develop a precise set of indicators.
