In this paper we generalise the risk models beyond the ordinary framework of affine processes or Markov processes and study a risk process where the claim arrivals are driven by a Cox process with renewal shot-noise intensity. The upper bounds of the finite-horizon and infinite-horizon ruin...

In this paper, we study a generalised CIR process with externally-exciting and self-exciting jumps, and focus on the distributional properties and applications of this process and its aggregated process. The aim of the paper is to introduce a more general process that includes many models in the...

In this paper, we study a bivariate shot noise Hawkes process. This process includes both externally excited joint jumps following a homogeneous Poisson process and two separate self-excited jumps, which are two Poisson cluster processes. A constant rate of exponential decay is included in this...
