Equations that describe the dynamics of state variable changes. • Model parameters that parameterize the equations. For instance, the stochastic volatility model introduced by Heston (1993) has two state variables (S and n), four model parameters (sS , sv , k and r) and the following stochastic differential equations (SDEs) to describe the dynamics: pﬃﬃﬃﬃ dSt =St ¼ mdt þ sS nt dWtS pﬃﬃﬃﬃ dnt ¼ kð1 À nt Þdt þ sn nt dWtn hdWtS ; dWtn i ¼ rdt: The model is as valuable (1) as many risk factors it has and (2) as rich the description of the dynamics of the risk factors is.
9 we show that the twice-extended Bates model is not only capable of capturing the volatility term structure dynamics, but in most cases the implied volatility skew dynamics also. There is only a short period during which the model was unable to explain the traded implied volatility skew of the EUR/USD exchange rate. However, this short period coincides with the stressed period after Lehman’s default when many traders marked the implied volatility skew based on some rulesof-thumb using some unrealistic, extreme parameters.
