The paper aims at presenting the status of informal institutions in Poland as well as indicating to what degree informal components of an institutional system are a good ground for the development of market economy. In Polish society, institutions associated with self-expression values prevail over those associated with survival values, which contributes to actuating the economic activity. However, the rationalism level is low and results from much stronger connections with tradition than in the case of citizens of many highly developed countries. Low level of trust in people is an indication of relatively poor efficiency of institutions, while great inclinations for non-observance of law reflect the inconsistence of informal vs. formal institutions.
