In this Lecture, I examine how complex securitization transactions may have created a “protection gap,” the conundrum that transaction parties may be unable to purchase or might not want to pay the price for full protection. As a result, they sometimes choose or are forced to assume the good...

We briefly introduce the financial crisis and the role played by mortgage-backed securities. Then we describe the controversy at issue: whether, in order to own and enforce the mortgage loans backing those securities, a special-purpose vehicle “purchasing” mortgage loans must take physical...

This accessible analysis of systemic risk regulation was delivered as the keynote speech at an October 20, 2011 European Central Bank conference on regulation of financial services. Many regulatory responses, like the Dodd-Frank Act in the United States, consist largely of politically motivated...
