Published in Risks : Optimal Form of Retention for Securitized Loans under Moral Hazard by Georges D

The authors address the moral hazard problem of securitization using a principal-agent model where the investor is the principal and the lender is the agent. Their model considers structured asset-backed securitization with a credit enhancement (tranching) procedure. They assume that the originator can affect the default probability and the conditional loss distribution. They show that the optimal form of retention must be proportional to the pool default loss even in the absence of systemic risk when the originator can affect the conditional loss given default rate, yet the current regulations propose a constant retention rate.
