Description: This paper describes risk-factor-dependent multiple decrements and actuarial cost functions as a general compartment model, a discrete time and discrete state stochastic model of morbidity and mortality processes. For large numbers of risk factors, the model is extended to its natural continuous time and state form. From Transactions of Society of Actuaries 1991, Vol. 43.

Description: This is a discussion on the paper of the same name.

Description: This paper will investigate the problem in estimating mortality rates using data obtained from insurance company records.

Description: This is a discussion about substandard mortality vs. standard mortality and the effects it will have on substandard premiums. Topics included: A. Statistical evidence on the trend of substandard mortality. Does it generally follow the trend of standard mortality? B. Effect this should have on substandard extra premiums. C. Does a lowering of substandard extras require any changes in underwriting rules, either as to the range of substandard classes or as to the ratings applied to some of the major impairments?

Description: This study covers all standard regular Ordinary issues of 1919 through 1951 exposed between 1948 and 1952 anniversaries, issued by the Prudential Insurance Company. There is a comparison of male to female mortality.

Description: In an increasing population the number of persons falls off from age to age more rapidly than does the stationary population of the life table. This can introduce a systematic bias into life table calculations. The first part of the paper describes an iterative procedure to correct for the bias, extends the method to multiple decrement and associated single decrement life tables, and demonstrates the magnitude of the bias involved. The second part of the paper summarizes the results of applying iterative life table techniques to 165 populations which encompass over a century's experience and include countries from all parts of the world. Followed by discussions submitted by several people

Description: This is the digest from the informal discussion reviewing the 1951 Impairment study. It is the latest in a series of studies covering mortality of impaired risks. It covers the experience under Ordinary insurance issued from 1935 to 1949 traced to the anniversaries in 1950. Standard and substandard policies were studied separately.

Description: This paper presents mortality rates by sex at ages 90 and above for persons who received retired worker benefits from the social security program for the first month that such benefits were paid. Followed by a discussion paper

Description: This paper examines the effects of selection procedures used in epidemiologic studies and suggests that similar procedures could be employed to select standard ordinary insurance risks at the older ages. The experience in this paper was developed from a prospective epidemiologic investigation launched by the American Cancer Society in the fall of 1959 to learn how personal characteristics, living styles, and environmental conditions influence health and longevity.
