Abstract

A pénzügyi válságok következményeként az elmúlt évtizedben középpontba került a szabályozás kérdése. A gyakorlatban szerzett tapasztalat és az elméleti modellek azt mutatják, hogy a likviditási kockázat és a túlzott kockázatvállalás csökkentése érdekében bevezetett szabályozói lépések hatására a piaci szereplők módosítják befektetési döntéseiket, sőt a szabályozói előírás visszahat a piaci likviditásra. Tranzakciós költséggel (eladási és vételi ár közötti árréssel) bővített általános egyensúlyelméleti modellt alkalmazunk a különböző eszközök likviditása és a bevezetett szabályozói előírás közötti kapcsolat vizsgálatához. A modellben a szabályozás hatására nő az árrés (a piaci likviditás csökkenésének mutatója), ami visszafogja a piaci szereplők közötti kereskedést és kockázatmegosztást. Egyensúlyban a piaci szereplők fogyasztási profilja kockázatosabb marad, alacsonyabb hasznossági szintet érnek el.* Journal of Economic Literature (JEL) kód: G11.
