Description: This paper uses the property-liability insurance companies as a research sample to investigate the relation between the enhancement of cost efficiency and the usage of reinsurance and financial derivatives as risk management tools. The stochastic frontier approach is applied to consider not only the mean of cost efficiency, but also its variance. The sample includes both organizational forms, namely, stock and mutual insurers.

Description: This research report study uses the property/liability insurance industry as a research sample to examine how risk management, financial management, and capital management are related to each another. This allows reflecting such relationships in: 1. the managerial decisions in the choice of derivative and reinsurance use. 2. the allocation of asset risks. 3. the determination of underwriting activities as well as liabiity risks. 4. the adequacy of capital levels.
