Description: This paper addresses the autoregressive model and shows that the boundedness restriction can be removed from the basic result on the probability of ruin. From Actuarial Research Clearing House 1991, VOL. 1.

Description: This paper studies the internal rate of return of a finite series of cash flows in terms of three natural axioms. Examples of rate of return functions are constructed and their economic significance is discussed. From the Actuarial Research Clearing House 1992 Vol. 1.

Description: The goal of this paper was to establish the main results of assigning internal rates of retum to arbitrary financial projects in a more general setting than that found in the theory of Teichrow, Robichek, and Montalbano. From Actuarial Research Clearing House 1993, VOL. 1

Description: This is an abstract of the paper entitled 'Axioms for the Valuation of Payment Streams: A Topological Vector Space Approach' by Approach by S. David Promislow. From Actuarial Research Clearing House, 1994, Vol. 1

Description: Given a financial transaction we are often interested in the number of internal rates of return [yield rates] and their location. From an actuarial point of view, the fundamental question is to identify those transactions with a single yield rate, or a single rate in some interval such as the positive reals. In this paper we are concerned with this counting problem. We survey various results concerning this problem, and provide a unifying approach together with some new insights.

Description: This is the abstract of a paper that builds on previous work concerned with measuring equity, and considers the problem of using observed claim data or other information to arrive at premiums which maximize equity. When these optimal premiums are used, it is shown that gathering more information or refining the risk classification must always increase equity.
