In this paper we develop a closed-form and thus computationally highly efficient formula to approximate the value of fixed-rate mortgage-backed securities (MBS). Our modelling framework is based on reduced-form and prepayment-risk-neutral valuation techniques and offers two major extensions...

In this study, we analyze why U.S. commercial banks failed during the recent financial crisis. We find that proxies for commercial real estate investments, as well as traditional proxies for the CAMELS components, do an excellent job in explaining the failures of banks that were closed during...

This paper provides an empirical study, which assesses the historical performance of credit rating agency (CRA) ratings for securitizations before and during the financial crisis. The paper finds that CRAs do not sufficiently address the systematic risk of the underlying collateral pools as well...

Recent history suggests that many boom-bust cycles are naturally driven by linkages between the credit market and asset prices. Additionally, new structured securities have been developed, e.g., MBS, CDOs, and CDS, which have acted as instruments of risk transfer. We show that there is a certain...

This paper analyzes the level and cyclicality of regulatory bank capital for asset portfolio securitizations in relation to the cyclicality of capital requirements for the underlying loan portfolio as under Basel II/III. We find that the cyclicality of capital requirements is higher for (i)...

Recent history suggests that many boom–bust cycles are naturally driven by linkages between the credit market and asset prices. Additionally, new structured securities have been developed, e.g., MBS, CDOs, and CDS, which have acted as instruments of risk transfer. We show that there is a...

With another real estate boom-bust bringing woes to the world economy, a quest for a better policy toolkit to deal with these boom-busts has begun. Macroprudential measures could be in such a toolkit. Yet, we know very little about their impact. This paper takes a step to fill this gap by...

In this paper we present a prepayment-risk-neutral valuation model for fixed-rate Mortgage-Backed Securities. Our model is based on intensity models as used in credit-risk modeling and extends existing models for individual mortgage contracts in a proportional hazard framework. The general...
