The key objective of insurance company on money management is asset liability management, as policy asset is solely for paying policy liability. It is true whether it is in case of life insurance, general insurance, or reinsurance. The difficulty of achieving such objective is that the exact cash flow and the exact duration of policy liability are unknown ex ante that requires the asset manager's a good quantitative, financial skill. What is worse is that the variations of cash flow and duration can be huge that is demanding on the asset manager's quantitative, financial skill. Quantitative problem is difficult but qualitative problem can be even more difficult. The specialist problem in insurance industry, which is also known as agency problem in information economics, is notorious. It is because a specialist may no longer work for the insurance company when the long term liability is due and the existing liability portfolio is always composed of myriad policies liability. / The purpose of this thesis is to try to provide solutions to three critical problems in insurance industry. (1) China is the most booming country for insurance at the moment. So, it is selected for discussing about the most difficult problem in modern finance---specialist problem. A structural approach is devised in this thesis to solve such problem. The solution can be generalized to all countries. (2) As many people argue about that modern finance is inapplicable to emerging market, such as China, especially when there are capital account and currency controls, the bond market of China is selected to provide evidence that modern finance is applicable to emerging market even both the capital account and the currency of the country are controlled by the government. (3) The last part of this thesis provides a breakthrough solution to price insurer default option, an embedded option, in insurance company using observable credit default swap price, as the traditional approach needs statistical assumption that is subjective. / Li, Wing Ping Desmond. / Adviser: Frank Youhua Chen. / Source: Dissertation Abstracts International, Volume: 70-06, Section: A, page: 2169. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 64-65). / Electronic reproduction.
