The number of insurance company has grown rapidly in Taiwan due to insurance deregulation since 1992. The main challenge insurance industry face is the declination of profit due to the increasing of competitors. The operator of insurance company is able to face this question and offer the solution, then a company has better solvency. So we explore two issue, one is to investigate the relationship between asset risk and capital adjustment decision in Taiwan¡¦s life insurance industry from 1993 to 2005, and the other is to provide some empirical evidences of retention limit of excess of loss reinsurance in Taiwan¡¦s property insurance industry.
In the first issue, a life insurance company is in less risk and has better solvency when it has more capital or higher ratio of capital; however, this also brings higher opportunity cost which means in long run, the average profit will be lower. There is no conclusion how to balance the relationship between capital adjustment and risk taking decision in life insurance industry though this topic is intensively discussed these days. Therefore, with the methodology of panel data threshold regression, we divide life insurance companies into two categories according to ¡§life insurance and annuity insurance premiums to total premiums ratio¡¨. One is life insurance Company of indemnification, and the other is the one of savings. In conclusion, we identify the negative correlation between capital ratio and risk of life insurance company of indemnification and the positive correlation between capital ratio and risk of life insurance company of savings.
In the second issue, because of the increase of natural disaster in Taiwan recently, the property insurance company has to face what the reinsurance companies are not willing to underwriter, so excess of loss reinsurance has become the viable solution in Taiwan¡¦s property insurance industry. We apply extreme value theory to the tail of Taiwan property insurance claim for VaR estimation and calculate retention limit of excess of loss reinsurance. The empirical results show that the distribution of Taiwan property insurance claim is fat-tailed. We suggested using Generalized Pareto Distribution (GPD) to model the data with extreme loss and conclude retention limit of excess of loss reinsurance.
