We consider a stochastic process S, the underlying dynamics of which involve a diffusion and a point process with a stochastic intensity: St = s0 (1 +Φ) Dt exp α− 1 2 σ t+ σWt where (Wt; t ≥ 0) is a Brownian motion, Φ is a random variable and the process (Dt; t ≥ 0) is defined by Dt = 1t≥T , with T is a random variable of exponential law. In such a framework, we aim at studying the following pr...
