The paper proposes a new class of continuous-time asset pricing models where whenever there is a negative jump in asset returns, it is simultaneously passed on to diffusion variance and the jump intensity, generating co-jumps of prices and volatility and jump clustering. To properly deal with...

The paper proposes a new class of continuous-time asset pricing models where negative jumps play a crucial role. Whenever there is a negative jump in asset re- turns, it is simultaneously passed on to diffusion variance and the jump intensity, generating self-exciting co-jumps of prices and...

This paper proposes a characteristic function-based method to estimate the time-changed Levy models, which take into account both stochastic volatility and infinite activity jumps. The method facilitates computation and overcomes problems related to the discretization error and to the...

We develop a new asset price model where the dynamic structure of the asset price, after the fundamental value is removed, is subject to two different regimes. One regime reflects the norma period where the asset price divided by the divided is assumed to follow a mean-reverting process around a...

The transformed-data maximum likelihood estimation (MLE) method for structural credit risk models developed by Duan [Duan, J.-C., 1994. Maximum likelihood estimation using price data of the derivative contract. Mathematical Finance 4, 155-167] is extended to account for the fact that observed...

A common belief is to qualify the credit default swap (CDS) market as very liquid. However, looking at intra-daily CDS data on individual firms from a major inter-dealer broker, we find only limited support for this view. In fact, bid-ask spreads and daily number of trades in our CDS data are...

We develop a multivariate credit risk model for the term structures of sovereign and bank credit default swaps. First, we separate the probability of joint defaults of large Eurozone sovereigns (systemic risk) from that of sovereign-specific defaults (country risk). Then, we quantify individual...
