WebOct 6, 2024 · In this paper, we investigate the pricing of basket-spread options with default risk under Hawkes jump-diffusion processes. A self-exciting Hawkes process is … WebThe intensity of the Hawkes process is given by the sum of a baseline intensity and other terms that depend on the entire history of the point process, as compared to a standard Poisson process. It is one of the main methods used for studying the dynamical properties of general point processes, and is highly important for credit risk studies.

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.
