Description: The classical approach to life contingencies has treated actuarial functions as fixed quantities. In point of fact, these functions really represent the mean or expected values of random variables which are functions at the length of time to death of a life aged x. In this paper, we will present some examples of this approach. Talk given at the thirteenth annual Actuarial Research Conference held at Ball State University, Muncie, Indiana, September 1, 1978.

Description: This is a proof on Lidstone's theorem. It contains formulas for calculating policy dividends.

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

Description: In a paper entitled ‘Using Cash Flows to Allocate Investment Income’ [ARCH 1979.1] reference was made to the conversion of investment rates [and capital gain and loss rates] from rates based upon periods of original contribution to rates based upon dollars of original contribution. Thus arose the topic of this note.

Description: In a recent Society of Actuaries' regional meeting, there was a discussion on an age-old actuarial problem. Within the same company, should the return on equity ROE target vary by profit center depending upon the risk of the profit center?

Description: Thailand has been experiencing a high and rapid HIV infection growth rate due to a combination of exotic new strains of the HIV, heavy intravenous drug use, a flourishing commercial sex industry and entrenched high-risk behavior by Thai males. Although major uncertainties remain about the HIV/AIDS epidemic in Thailand, one thing is certain: HIV infection will continue to spread. Therefore Thai life insurance companies have to make plans for coping with the consequences of this epidemic.

Description: This paper reviews Redington's theory of immunization and sketches how it may be extended to the general case of stochastic flows by means of modern option-pricing theory. From the Actuarial Research Clearing House 1992 Vol. 1 .

Description: Interest rate modeling is discussed in this paper with special emphasis on the long and short rate model of Brennan and Schwartz. Comment is made on an unexpected aspect of the solution of the resulting partial differential equation. Also, an analysis is made of the predictive power of the term structure of interest rates. From the Actuarial Research Clearing House 1991 Vol. 1.

Description: The objectives of this paper are to determine the extent to which Makeham's or Gompertz's laws describe recent insurance and population mortality analyze how the constants in the two laws vary with respect to some factors and propose a simple extension to Makeham's law to account for recent departures from the laws, related to difference in sex.
