Description: This paper investigates the optimal multi-period proportional reinsurance strategy that minimizes the ruin probability of an insurer. Some conditions under which it is optimal to have no reinsurance are derived. Based on these results, a new concept, capital threshold of proportional reinsurance, is introduced. In the case of two periods, a lower bound of the capital threshold of proportional reinsurance is provided. Some economic implications and properties of this new concept are also discussed.

Description: Studies default risk through the two-sided exit problem of a time-homogeneous di§usion process with tax payments of loss-carry-forward type and obtains explicit formulas for the exit probabilities. If the lower boundary is understood as the default threshold, then the nondefault probability is solved as a special case. A sufficient and necessary condition for the tax identity is discovered.

Description: Many top-performing businesses aren’t just risk aware, but rather risk intelligent. Such a posture helps prepare companies for a major event and can demonstrate to a regulator or auditor that an appropriately strong control framework is in place. Better still, companies gain real strategic value from a “risk adjusted” understanding not only of their threats and vulnerabilities, but also the upside opportunities associated with various risks. It starts with having both qualitative and quantitative information to identify, assess and manage risks. Strategic risk management, at its core, is about creating value by increasing transparency and accountability, and quality of information. More than a mere compliance exercise, effective risk management enables more informed strategic decision making, increased accountability and transparency, a greater likelihood of organizational success, and – ultimately – competitive advantage, as borne out by many studies that correlate risk management and financial results.

Description: Investment Fallacies: The Misconceptions of Retirement Risks

Description: Presented at May 2005 Spring Meeting. This session examines financial, economic and traditional actuarial methodological approaches used for solving investment-risk problems.

Description: This session at the 1998 Valuation Actuary Symposium gives an overview of risk management. Two example company programs are described. The use of value at risk as a measure is discussed.

Description: This paper discusses a model that is used for the loss process, ratemaking problem and risk classification.

Description: This is a sequel to author's earlier paper on Installment Premiums. This paper explores the parallel case of apportionable premiums, another situation in which a special adjustment payment at death causes an otherwise somewhat complex policy to be identical with a more simple and familiar one. As with installment premiums, this will result in terminal reserves for the complex policy being exactly equal to those for its corresponding familiar policy.

Description: This paper thoroughly describes risk premium calculation based on an insurance portfolio consisting of policies risks insured over a finite time interval.
