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.

Description: In this paper population mortality rates are used to explore the question of whether a biologically determined maximum age actually exists for the human species. From Actuarial Research Clearing House 1993, VOL. 3.

Description: The differences between select and ultimate insurance mortality are usually explained in terms of: 1. deterioration of a person's physical condition which occurs due to aging, and 2. anti-selection which occurs as some policyholders allow their coverage to lapse [i.e., those policyholders who find their health has become poor keep their coverage, while those who remain healthy discontinue their insurance]. This paper explores the differences in mortality between companies related to the differences in lapse rates of the companies.

Description: This paper discusses a general model for calculating life contingencies including formulation of the model and net reserves and contingency reserves.

Description: There are three commonly used methods for compiling exposure and death data for use in obtaining crude mortality rates. They are lives, policies and amounts of insurance. This paper investigates the properties of estimators based on lives, amounts and robust alternatives. It is concluded that lives provide the best estimator, even when there is a moderate dependence of mortality rates on amounts of insurance.

Description: Statistical properties of interest, annuity and insurance functions are examined when mortality and interest are treated as having a random component. Several special models of interest rate fluctuation are examined in detail. It is hoped that such theory will be useful in developing fluctuation reserves and premium margins. Presented at the 13th Annual Actuarial Research Conference, Ball State University, August 31st. September lst, 2nd. 1978.

Description: The theory underlying the Moving Weighted Average graduation method is restated in the language of linear algebra which provides for an enrichment of the family of formulas. A comparison of the results of applying six members of the family to 100 simulated data sets is provided.

Description: This paper reviews data from the accident study for years 1930-1935 to see if there are any relationships between disabled worker mortality and standard mortality that might endure to the present. From the Actuarial Research Clearing House ARCH 1990 Vol. 1.

Description: This is the abstract of the referenced paper which studies the mortality of left-handed baseball players versus that of right-handed players by examining the times and ages of death of more than 6,000 players who died before 1990. From Actuarial Research Clearing House 1994, VOL. 1.

Description: This study provides statistical indications of trends in mortality at ages 10 through 34 for both males and females in Canada. Causes of death, with emphasis on suicide and accidental death rates, are explored.
