Did Securitization Affect the Cost of Corporate Debt?

This paper investigates whether the securitization of corporate bank loans had an impact on the price of corporate debt. Our results suggest that loan facilities that are subsequently securitized are associated with a 15 basis point lower spread than that of loans that are not subsequently securitized. To identify the particular role of securitization in loan pricing, we employ a difference in differences approach and consider loan characteristics that are associated with the likelihood of securitization. We document that Term Loan B facilities, facilities originated by banks that originate CLOs, and loans of B-Rated firms are securitized more frequently than other loans. Spreads on facilities estimated to be more likely to be subsequently securitized have lower spreads than otherwise similar facilities. The results are consistent with the view that securitization caused a reduction in the cost of capital.

Why Did U.S. Banks Invest in Highly-Rated Securitization Tranches?

We estimate holdings of highly-rated tranches of mortgage securitizations of American deposit-taking banks ahead of the credit crisis and evaluate hypotheses that have been advanced to explain these holdings. We find that holdings of highly-rated tranches were economically trivial for the typical bank, but banks with greater holdings performed more poorly during the crisis. Though univariate comparisons show that banks with large trading books had greater holdings, the holdings of highly-rated tranches are not higher for banks with large trading books in regressions that control for bank size. The ratio of highly-rated tranches holdings to assets increases with bank assets, but not for banks with more than $50 billion of assets. This evidence is inconsistent with explanations for holdings of highly-rated tranches that emphasize the incentives of banks deemed “too-big-to-fail”. Further, the evidence does not provide support for “bad incentives” theories of holdings of highly-rated tranches. We find, however, that banks active in securitization held more highly-rated tranches. Such a result can be consistent with regulatory arbitrage as well as with securitizing banks holding highly-rated tranches to convince investors of the quality of these securities. Our evidence supports the latter hypothesis.

MBS Ratings and the Mortgage Credit Boom

We study credit ratings on subprime and Alt-A mortgage-backed securities (MBS) deals issued between 2001 and 2007, the period leading up to the subprime crisis. The fraction of highly-rated securities in each deal is decreasing in mortgage credit risk (measured either ex-ante or ex-post), suggesting ratings contain useful information for investors. However, we also find evidence of significant time-variation in risk-adjusted credit ratings, including a progressive decline in standards around the MBS market peak between the start of 2005 and mid-2007. Conditional on initial ratings, we observe underperformance (high mortgage defaults and losses, and large rating downgrades) amongst deals with observably higher-risk mortgages based on a simple ex-ante model, and deals with a high fraction of opaque low-documentation loans. These findings hold over the entire sample period, not just for deal cohorts most affected by the crisis.

Students bring Potlatch history to life

A newspaper article originally published in the Moscow-Pullman Daily News. The article is about a collaboration between the Potlatch Historical Society and Diane Kelly-Riley's digital humanities class at the University of Idaho in which Kit Stokes and other students in the class used PHS records to tell stories about Potlatch history in new ways. The class culminated in a social event at the WI&M Depot during which the students presented their work to Potlatch community members
