First passage time brownian motion
Webjumps in the underlying credit spreads. In the framework of first passage time models we extend the model introduced in [Overbeck and Schmidt, 2005] to address these issues. In the extended a model, a credit quality process is driven by an Itˆo integral with respect to a Brownian motion with stochastic volatility. Using a representation of WebFirst-passage times of two-dimensional Brownian motion 1047 Table 1: In this table we summarize existing results on the first-passage time problem of correlated Brownian motions (except Sacerdote et al. [24], in which several joint densities in a more general setting of diffusion processes were obtained), where 'not available' is denoted as ...

WebI would like to obtain the law of the first hitting time of a geometric Brownian motion. More precisely, to compute P [ τ B ≤ T] where τ B := inf { 0 ≤ t ≤ T: X t ≤ B } and X = ( X t) t ≥ 0 is a geometric brownian motion of drift μ and volatility σ with initial condition X 0 > B. WebFeb 4, 2016 · Nearly fifty years after the introduction of skew Brownian motion by Itô and McKean (1963), the first passage time distribution remains unknown. In this paper we …
