报告题目: Optimal reinsurance control under continuous time models

报告人: 孟辉(中央财经大学)

摘要: Based on a class of premium principle (including exponential premium principle, expected value premium principle and variance premium principle, etc.), we consider some optimal reinsurance problems to minimize the probability of ruin and to maximize the expected utility under a diffusion process and jump risk process. The optimal reinsurance strategy with nontrivial structure, different from proportional reinsurance strategy and excess of loss reinsurance strategy, etc., is given. Then the optimal value function is obtained also. Finally, we provide some numerical analysis.

报告题目: Time-consistent mean-variance portfolio selection: a log-return model

报告人: 陈平(澳大利亚墨尔本大学)

摘要: This paper investigates a continuous-time mean-variance portfolio selection problem based on a log-return model. The financial market is composed of one risk-free asset and multiple risky assets whose prices are modelled by geometric Brownian motions. We derive a sufficient condition for an open-loop strategy via the forward backward stochastic differential equation (FBSDE) framework. The equilibrium strategy is derived by solving a system of FBSDEs. To illustrate our result, we consider a special case where the interest rate is given by the Vasicek model. We also derive the close-loop equilibrium strategy through the dynamic programming approach. A comparison between the open-loop and close-loop strategies are conducted.

报告题目:The general draw-down times for spectrally negative Levy processes

报告人:Xiaowen ZHOU (Concordia University)

摘要: A draw-down time for a stochastic process is a downward first passage time that depends on the running maximum of the process. In this talk, for spectrally negative Levy processes we find expressions of several joint Laplace transforms involving general draw-down times. The results are expressed in terms of scale functions. Applications in risk models will be discussed. This talk is based on joint work with Florin Avram, Bo Li and Nhat Linh Vu.
