报告内容:We consider a risk process as the unique solution to stochastic differential equation driven by both a Brownian motion with two-valued drift and a symmetric local time process at a certain level. Such a process can be identified as a toy model with regime switching that depends on whether the process takes values above or below the level.
In this talk we first present some fluctuation results for such a process and then apply them to study a stochastic control problem that is motivated by the optimal dividend problem for risk processes. We identify conditions for different barrier strategies to be optimal and observe that certain band strategies involving two dividend barriers can be optimal.
This talk is based on joint work with Zhongqin Gao.
