Best-Practices in Mortgage Default Risk Measurement and Economic Capital
Best-Practices in Mortgage Default Risk Measurement and Economic Capital
Each of the major processes used by industry participants to measure
so-called “credit risk” for first mortgage products. The study has three
sections:
Section I provides a discussion of the general concept of Economic
Capital (“EC”), how EC is measured and used by best-practice banks,
and how EC concepts used by industry practitioners differ from
regulatory definitions of capital.
Section II discusses the various types of theoretical “credit risk
models” that are used by practitioners to measure EC for mortgages.
Section III conducts several empirical experiments in which large
historical databases are used to estimate the credit risk models
described in Section II. The empirical work is aimed at helping
the practitioner and the regulator to evaluate the results of
alternative models.
