A Two-Phase Dynamic Contagion Model for COVID-19

Zezhun Chen, Angelos Dassios, Valerie Kuan +4

In this paper, we propose a continuous-time stochastic intensity model, namely, two-phase dynamic contagion process(2P-DCP), for modelling the epidemic contagion of COVID-19 and in…

Parisian excursion with capital injection for draw-down reflected Levy insurance risk process

Budhi Surya, Wenyuan Wang, Xianghua Zhao +1

This paper discusses Parisian ruin problem with capital injection for Levy insurance risk process. Capital injection takes place at the draw-down time of the surplus process when i…

Generalized Phase-Type Distribution and Competing Risks for Markov Mixtures Process

B. A. Surya

Phase-type distribution has been an important probabilistic tool in the analysis of complex stochastic system evolution. It was introduced by Neuts \cite{Neuts1975} in 1975. The mo…

Optimal double stopping of a Brownian bridge

Erik J. Baurdoux, Nan Chen, Budhi A. Surya +1

We study optimal double stopping problems driven by a Brownian bridge. The objective is to maximize the expected spread between the payoffs achieved at the two stopping times. We s…
