Description: Since detailed claim information is not readily available to the Committee on Group Mortality and Morbidity on an annual basis, a special investigation of group hospital expense experience has been conducted. That investigation is summarized in this paper, and covers plan descriptions, morbidity and cost data, and continuation tables.

Description: This paper investigates the accuracy of loss reserves by comparing some reserves with the actual results five years hence. The ultimate purpose was to provide an estimate of the amount of variability which cannot be explained by listed factors. The resulting amount of variability gives an indication of the amount required for a provision for adverse deviation. From Actuarial Research Clearing House 1991, VOL. 1

Description: This paper presents population hospital utilization data concerning the proportion of total hospital days that is due to injury and the proportion of total hospital days that is spent in intensive care units for use in obtaining reserve factors. The paper also presents continuation data for hospitalizations. From Transactions of Society of Actuaries 1979, Vol. 31.

Description: At the end of 1963 health insurance claim reserves and liabilities held by companies on this continent totaled well over one billion dollars. This paper seeks to study the problems involved in calculating these reserves and liabilities and to describe the methods in use. From Transactions of Society of Actuaries 1964, Vol. 16, Pt. 1, No. 44 AB.

Description: This paper examines the details of group major-medical expense insurance, a disability coverage, also labeled as catastrophe coverage. From Transactions of Society of Actuaries 1951, Vol. 3, No. 7.

Description: This paper presents a procedure for calculating aggregate stop-loss premiums that takes parameter uncertainty into account. From Actuarial Research Clearing House ARCH 1988, Vol. 3

Description: A mathematical framework for benefits and choices must be created, in order to model flexible benefit selection. This paper creates such a framework by defining benefit plans as reimbursement functions. These are then used with a defined choice function to calculate the cost deviation due to selection. From Actuarial Research Clearing House 1992, VOL. 1.

Description: In this paper, a model is proposed as a potential explanation for the steady deterioration in loss ratios often observed on blocks of individual health insurance policies. This model, which incorporates assumptions of anti-selective lapses, can be used for morbidity projections and projections of the effects of rate increases. Discussions of this paper are included.

Description: This paper develops a parametric model for health care insurance claims using currently available software to fit parametric models to the data. Model selection is based on the Chi-squared goodness-of-fit test and a comparison of the empirical limited expected value function to parametric limited expected value functions. From Actuarial Research Clearing House 1993, VOL. 3.

Description: This paper presents a method involving re-sampling 'with replacement but without random numbers', numerical convolutions for sums and quotients, and estimation of confidence intervals for trend in average size claim. In this paper, this method is applied to major medical claims.
