英文摘要:
We prove that a large class of discrete-time insurance surplus processes converge weakly to a generalized Ornstein-Uhlenbeck process, under a suitable re-normalization and when the time-step goes to 0. Motivated by ruin theory, we use this result to obtain approximations for the moments, the ultimate ruin probability and the discounted penalty function of the discrete-time process.

中文摘要:
我们证明了一大类离散时间保险盈余过程在适当的重新规范化下,当时间步长为0时,弱收敛于广义Ornstein-Uhlenbeck过程。受破产理论的启发,我们利用这一结果获得了离散时间过程的矩、最终破产概率和贴现惩罚函数的近似值。
