15.5 Further Reading
A stochastic volatility model with jumps comparable to the BNS model is the so-
called COGARCH(1 , 1) process introduced by Klüppelberg et al. [105]. This model
is a continuous time version of the popular GARCH model in discrete time and
states that the asset log-price X is given by d X t =
σ t d L t , where L is a Lévy pro-
cess and the jumps L of this Lévy process are also used to define the volatility
process σ . The model is generalized to the COGARCH( p,q ) process by Brockwell
et al. [30].
A large class of stochastic volatility models is described by Carr et al. [37] where
the stock price process S is given as the ordinary or the stochastic exponential of a
stochastic volatility process Z t =
L Y t , which is obtained by subordinating a Lévy
process L to Y (which, for example, is given by the CIR model).
