This paper examines whether securitization has an ex-post effect on residential loan renegotiation. It makes two main contributions to the existing literature. First, this paper evaluates the re-default and self-cure rates of loans using bank-reported loan renegotiation data. Second, it conducts a transition probability study to better understand the re-default and self-cure dynamics by time and previous loan state. I find that previously delinquent portfolio loans are less likely to re-default and more likely to self-cure than comparable securitized loans during the intermediate time frame, but the difference diminishes afterwards. For previously cured loans, portfolio loans and securitized loans have generally similar re-default and self-cure rates over time. This paper emphasizes that it is important to understand the dynamic transition behavior of mortgage loans.

[We show that Treasury security prices in the secondary market decrease significantly in the few days before Treasury auctions and recover shortly thereafter, even though the time and amount of each auction are announced in advance. These results are linked to dealers' limited risk-bearing capacity and end-investors' imperfect capital mobility, highlighting the important role of frictions even in very liquid financial markets. Our results imply a hidden issuance cost to the U.S. Department of the Treasury, estimated to be 9 to 18 bps of the auction size, or over half a billion dollars for the issuance size in 2007.]
