Computing Quantiles in Regime-Switching Jump-Diffusions with Application to Optimal Risk Management: a Fourier Transform Approach
regime switching jump-diffusion models Value at Risk risk management Fourier transform methods.
2012/9/14
In this paper we consider the problem of calculating the quantiles of a risky position,the dynamic of which is described as a continuous time regime-switching jump-diffusion, by using Fourier Transfor...

We provide a complete characterization of the class of one-dimensional time-homogeneous di usions consistent with a given law at an exponentially distributed time using classical results in di usion t...

We discuss suitable classes of diffusion processes, for which functionals relevant to finance can be computed via Monte Carlo methods. In particular, we construct exact simulation schemes for processe...

Stationarity-based specification tests diffusions when the process nonstationary
2014/3/13
We analyze in this paper the asymptotic behavior of the specification test of Aït-Sahalia (1996) for the stationary density of a diffusion process, but when the diffusion is not stationary. We co...

Regularity of the Optimal Stopping Problem for Levy Processes with Non-Degenerate Diffusions
Regularity Levy Processes Non-Degenerate Diffusions
2010/10/29
The value function of an optimal stopping problem for a process with L´evy jumps is known to be a generalized solution of a variational inequality. Assuming the diffusion component of the proces...
