- ItemAsymmetric trading responses to credit rating announcements from issuer- versus investor-paid rating agencies(John Wiley and Sons, Ltd, 2024-01) Nguyen QMP; Do HX; Molchanov A; Nguyen L; Nguyen NHThe credit rating industry has traditionally followed the “issuer-pays” principle. Issuer-paid credit rating agencies (CRAs) have faced criticism regarding their untimely release of negative rating adjustments, which is attributed to a conflict of interests in their business model. An alternative model based on the “investor-pays” principle is arguably less subject to the conflict of interest problem. We examine how investors respond to changes in credit ratings issued by these two types of CRAs. We find that investors react asymmetrically: They abnormally sell equity stakes around rating downgrades by investor-paid CRAs, while abnormally buying around rating upgrades by issuer-paid CRAs. Our study suggests that, through their trades, investors capitalize on value-relevant information provided by both types of CRAs, and a dynamic trading strategy taking advantage of this information generates significant abnormal returns.
- ItemLiquidity constraints, home equity and residential mortgage losses(2016-06-30) Do HX; Rosch D; Scheule HThis paper analyses how borrower liquidity constraints and home equity relate to the realized loss given default (LGD) using the quarterly U.S. residential mortgage loan-level data observed from Q2 2005 to Q1 2015. We define defaulted loans with zero-LGD as cure loans and those with non-zero LGD as non-cure loans. We find robust evidence that the borrower liquidity constraints and positive equity are explaining cure, while negative equity explains non-zero loss. However, a relationship between borrower liquidity constraints and the non-zero LGD is not economically meaningful. Our findings support to separate cure and non-cure loans in mortgage loss risk models.
