Title: Valuation Models in Regulation
Abstract: This paper surveys and critiques the financial models of the firm used in rate of return regulation. The increasingly wide assortment of models used in rate of return cases might appear to promise a rich classification of contrasting assumptions and a diverse catalogue of model constructs. Nothing could be further from the findings of this paper. It is shown that all models considered have assumed either explicitly or implicitly the financial market conditions used in the development of the original Modigliani and Miller (M-M) model of 1961. Thus, the consequences, criticisms, and attributes of the Modigliani-Miller financial world seem to represent the current state of rate of return modeling.
