We document the fact that servicers have been reluctant to renegotiate mortgages since the foreclosure crisis started in 2007, having performed payment-reducing modifications on only about 3 percent of seriously delinquent loans. We show that this reluctance does not result from securitization:...

This paper develops and estimates an instrumental variables strategy for identifying the causal effect of securitization on the incidence of mortgage modification and foreclosure based on the early-payment default analysis performed by Piskorsi, Seru, and Vig (2010). Estimation results show that...

In this note we discuss the findings in Piskorski, Seru, and Vig (2010), as well as the authors' interpretation of their results. First, we find that small changes to the set of covariates used by PSV significantly reduce the magnitude of the differences in foreclosure rates between securitized...

A central result in the theory of adverse selection in asset markets is that informed sellers can signal quality by delaying trade. This paper uses the residential mortgage market as a laboratory to test this mechanism. Using detailed, loan-level data on privately securitized mortgages, we find...

A leading explanation for the lack of widespread mortgage renegotiation is the existence of frictions in the mortgage securitization process. This paper finds similarly small renegotiation rates for securitized loans and loans held on banks' balance sheets that become seriously delinquent, in...

This paper examines how the government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac, the largest investors in subprime private-label mortgage-backed securities (PLS), influenced the risk characteristics and prices of the deals in which they participated. To identify the causal effect...
