WebJan 1, 2024 · In this paper, we price foreign equity options by using mutually exciting Hawkes jump–diffusion processes to model the dynamics of the exchange rate and the underlying foreign asset. WebPoisson process, however, λ is deterministic; i.e. λ(t) depends only on t. A stationary Poisson process has constant conditional rate: λ(t) = α, for all t. This model posits that the risk of an event is the same at all times, regardless of how frequently such events have occurred previously. For a non-stationary Poisson process, λ(t) is some physics kmpp
