Description: In writing this note on the relationship between total return, duration and convexity, it was author's intent to produce a better understanding of Redington's theory of immunization. From Actuarial Research Clearing House 1991, VOL. 2.

Description: Option bounds are obtained in a discrete-time framework with transaction costs. The model represents an extension of the Cox-Ross-Rubinstein binomial option pricing model to cover the case of proportional transaction costs. The method proceeds by constructing the appropriate replicating portfolio at each trading interval. From Actuarial Research Clearing House 1991, VOL. 1.

Description: This paper presents the application of the asset share technique of pricing to Home Equity Line of Credit insurance. The paper's objective is to provide useful tools when developing a new HELOC product including projections for marketing and underwriting, distinctions between desirable and undesirable product design features, and development of premium rate structures. From Actuarial Research Clearing House 1990, VOL. 2

Description: This abstract describes a paper that considers an optimal investment and risk control problem for an insurer under the mean-variance criterion.

Description: This paper describes a new approach of calculating duration by taking a portfolio perspective utilizing the idea of internal rate of return. It is presumed the user has a model for projecting cash flows under different interest rate scenarios and knows the current market value of the portfolio. From Actuarial Research Clearing House 1993, VOL. 3.

Description: This is a summary of the talk given at the 27th Actuarial Research Conference regarding ruin theory. From Actuarial Research Clearing House 1993, VOL. 1.

Description: Many seniors who own houses in the United States have most of their wealth in their houses. Home Equity Conversion Mortgages are designed to allow seniors to borrow money against their house. This paper describes a stochastic simulation approach used to estimate the amount of a level-payment annuity payable as long as the senior is alive and living in his/her home. From Actuarial Research Clearing House 1990, VOL. 2.

Description: This report looks at closed form models or 'exact solutions' in which calculus produces 'simple' formulae. The conclusion is that for Gaussian interest rate models we can solve the problem of an American option provided the option holder behaviour can be described by a force of option exercise which is linear or quadratic in the state variables.

Description: This paper discusses simple interest, amortization and simplicity. The author asserts that compound interest is an improvement upon simple interest that makes the calculation of interest simpler. Likewise, exponential amortization is an improvement upon linear amortization that makes the calculation of amortization simpler. From Actuarial Research Clearing House 1990, VOL. 2.
