Cécilia Mancini (Università di Verona) Warnings about Future Jumps: Properties of the Exponential Hawkes Model

We analyze jump risks in financial asset prices modeled by Ito semimartingales with an exponential Hawkes process as the jump counter.

First, using little information, we estimate the probability that an observed jump cluster is not yet exhausted. Second, we make explicit the conditional density of consecutive jump durations and prove that durations stochastically increase. Third, we provide bounds for jump probabilities in consecutive time intervals.

Application to 5-minute US returns shows that cluster depletion probabilities strongly correlate with the expected yearly jump count, and improve forecasts of jumps and realized variance.

Joint work with Rachele Foschi, University of Pisa, and Francesca Lilla, Bank of Italy

Manon Costa (IMT) Some limit theorem for inhibited Hawkes processes with finite memory.

In this talk, I will present some recent result on the long-time behaviour of inhibited Hawkes processes both in continuous and discrete time. In particular, we will stress the complex role of inhibition in the stability of Hawkes processes.
