In this paper, we explore the optimal price, default ratio, and capital for insurance companies under social welfare maximization from regulators' perspective. By comparing cases under symmetric and asymmetric information in the insurance market, we find that an optimal regulatory objective...

In this article, a model of optimal insurance pricing and investment strategies is established. The insurance price, investment returns and insured losses are assumed to be correlated stochastic processes. N kinds of invested risky assets following multi-Vasicek model with time-varying...

In this paper, time-inconsistent model was established under stochastic differential game framework. The investment portfolio includes multi-risky assets, whose returns are assumed to be correlated in a time-varying manner and change cyclically. The claim losses of insurance companies and...

This work considers stochastic models of defined benefit pension plans. Stochastic growth rate of salary, and stochastic mortality is allowed to evaluate pension plan. Especially important thing is that based on Momon (2004), we extend Vasicek model to multi-dimentional cases and use it to mode...
