In contrast, when most loans are securitized and originators have little financial or reputational capital at risk, the danger exists that the originators of loans will be less diligent. In securitization markets, therefore, monitoring the originators and ensuring that they have incentives to make good loans is critical.
I have argued elsewhere that, in some cases, the failure of investors to provide adequate oversight of originators and to ensure that originators' incentives were properly aligned was a major cause of the problems that we see today in the subprime mortgage market (Bernanke, 2007).
