Consider the optimal dividend problem for an insurance company whose uncontrolled surplus precess evolves as a spectrally negative Levy process. We assume that dividends are paid to the shareholders according to admissible strategies whose dividend rate is bounded by a constant. The objective is...

This paper studies some asymptotic results for both finite and ultimate ruin probabilities in a discrete time risk model with nonconstant interest rates, under the assumptions that the individual net losses are bivariate upper-tail independent, identically distributed random variables having a...

This paper stidies the first passage times to constant boundaries for mixed-exponential jump diffusion processes. Explicit solutions of the Laplace transforms of the distribution of the first passage times, the joint distribution of the first passage times and undershoot (overshoot) are...
