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.
