Zjawisko nadmiernej procykliczności sektora finansowego z perspektywy polityki makroostrożnościowej – źródła, metody ograniczania i ich rudymentarne słabości

This article presents explanations of the procyclicality phenonomenon with the application of the theory of market failures and behavioral finance. This analysis shows that the most important failures include: externalities of strategic complementarities (the classical herding phenomenon), fire sale externalities (i.e. asset prices spirals); network externalities (i.e. contagion risk). The theory of market failures does not say the whole story about the procyclicality phenomenon. To get a fuller picture of procyclicality one has to resort to behavioral finance, i.e. availability heuristics and threshold heuristics. The analysis also focuses on macroprudential instruments in their potential to affect financial cycle and soundness of financial sector. The article aims also to identify basic limitation of macroprudential policy instruments.
