Description: In this paper the authors analyze data from group medical expense insurance claims and show that many insurance loss distributions have very 'heavy tails' because large losses represent a disproportionate fraction of the total cost. They also present a simple model to reproduce and explain the large loss behavior. From Actuarial Research Clearing House 1990, VOL. 2

Description: This report has been assembled by the Task Force as a comprehensive guide to practicing actuaries in evaluating the impact of AIDS on the solvency of life and health insurance companies in the US and Canada. From Transactions of Society of Actuaries 1988, Vol. 40, Pt. 2.

Description: This paper provides a method for estimating long-tailed unpaid losses from paid loss development using trended generalized bondy development. From Actuarial Research Clearing House 1993, VOL. 3.

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: 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: 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.
