The technique of securitization was at the heart of the financial crisis (for a primer on securitization, read here). Originally a sound instrument to mitigate risk, the standards of the securitization process degraded in the years leading up to the financial crisis, which contributed to excessive credit growth in and outside of the formal banking system (read here). In a recent paper, professor Schwarcz (Duke) reviews, compares and critiques the post-financial crisis regulatory responses to securitization in the United States and Europe (see, here).
