Following Mehra (1975) we indicate how some of the well known credibility models may be formulated as Kalman filters. The formulation yields recursive premium forecasts including recursive predictions errors which are of importance to practitioners.

This paper describes a consistent and justifiable means of establishing adequate claims provisions in General Insurance. The topic has created widespread interest amongst actuaries, accountants and regulatory authorities.

This paper presents an abbreviated history of the events leading up to Medicare and the impact of Medicare since its inception upon the health care system and health care costs. Because of the social pressures brought about by ever increasing health care costs, especially to the elderly, Medi Gap policies, their benefits and pricing, have come under close scrutiny of the regulator.

This paper discusses aggregate loss distributions from the perspective of collective risk theory. An accurate, efficient and practical algorithm is given for calculating cumulative probabilities and excess pure premiums. The input required is the claim severity and claim count distributions. One of the main drawbacks of the collective risk model is the uncertainty of the parameters of the claim severity and claim count distributions.

Aggregate losses are easily defined as the sum of individual claims, but the distribution of aggregate losses has not been easy to calculate. In fact, this has been a central, and perhaps the central, problem of collective risk theory.

This is a remarkable piece of synthesis! It finds a thread running through many significant papers in our Proceedings and weaves an entirely new fabric which, when reviewed on an overall or on a modular basis, should make life much simpler for both the student and the practicing actuary. The author recognizes that mathematicians constantly strive for generalizations which provide solutions for superficially different problems.

The paper is concerned initially with the admissibility of particular claim payment models. Admissibility is restricted by the requirement that, if claims escalation is excluded, the amount of outstanding claims at any epoch of development of a generation of claims should be independent of the future speed of finalization.
This simple requirement represents an invariance condition.

This paper proposes a new version of the collective risk model that allows for uncertainty in selecting the expected number of claims and the claim severity distribution. We provide two different methods of estimating the parameters of this model. It is demonstrated by computer simulation that one must combine the experience of several insureds in order to accurately quantify parameter uncertainty.

An application of the previous paper on multiple regression risk models to analysis of IBNR losses.

This paper starts with a risk-theoretic (frequency and severity distributions) model but allows the parameters of this model to vary. Albrecht uses maximum likelihood estimators for parameter estimation. The structure of the model allows the parameters to vary by accident year and thus introduce flavor of the adaptive models.
