Copula CDO-modell

Copula CDO-modellen (Li 2000) bruker Gaussiske kopulaer for å prise collateralized debt obligations (CDO-er) ved å modellere felles sannsynligheter for mislighold på tvers av en portefølje av obligasjoner. Modellen ble industristandarden for CDO-prising, men ble sterkt kritisert etter 2008 for å undervurdere halerisiko og korrelasjonsbrudd under kriser.
