Default risk in equity returns can be measured by structural models of default. In this paper we propose a credit warning signal (CWS) based on the Merton default risk (MDR) model and a Regime-switching default risk (RSDR) model. The RSDR model is a generalization of the MDR model, comprises...

In this paper, we present a novel method to extract the risk-neutral probability of default from American put option prices. Under the assumptions of Carr and Wu (2011), we derive a closed form expression for American put options from which the probability of default can be inferred. Our...

This paper considers a simple model of credit risk and derives the limit distribution of losses under different assumptions regarding the structure of systematic and idiosyncratic risks and the nature of firm heterogeneity. It documents a rich and complex interaction between the underlying model...

Central bank lending to commercial banks is typically collateralized which reduces central bank's credit risk exposure to “double default events” when the counterparty and the issuer of the underlying collateral asset both default in a short period of time. This paper presents a simple model...

We present a simple procedure to construct credit curves by bootstrapping a hazard rate curve from observed CDS spreads. The hazard rate is assumed constant between subsequent CDS maturities. In order to link survival probabilities to market spreads, we use the JP Morgan model, a common market...

The new structural model of credit risk based on a normal firm value diffusion process can infer the firm value volatility from bank credit spreads that closely agreeing with the empirically estimated firm value volatility. We use the spread-implied firm value volatility as the model volatility...

Central bank lending to commercial banks is typically collateralized which reduces central bank's credit risk exposure to “double default events” when the counterparty and the issuer of the underlying collateral asset both default in a short period of time. This paper presents a simple model...

We generalize the asset dynamics assumptions of Leland (1994b) and Leland and Toft (1996) to a much richer class of models. By assuming a stationary corporate debt structure with constant principal, coupon payment and average maturity through continuous retirement and refinancing as long as the...
