Discounted Cash Flow techniques are the generally accepted methods for valuing firms. Such methods do not provide explicit acknowledgment of the value determinants and overlook their interrelations. This paper proposes a different method of firm valuation based on fuzzy logic and expert systems....

The Economic Value Added formally translates the theoretical notion of excess profit (also known as residual income). Its use is so firmly entrenched in applied corporate finance and management accounting that its name is often used as a noun for denoting the concept of excess profit itself....

This paper presents a new way of measuring residual income, originally introduced by Magni (2000a, 2000b, 2003). Contrary to the standard residual income, the capital charge is equal to the capital lost by investors. The lost capital may be viewed as (a) the foregone capital, (b) the capital...

This work presents a notion of residual income called Systemic Value Added (SVA). It is antithetic to Stewart’s (1991) EVA, though it is consistent with it in overall terms: a project’s Net Final Value (NFV) can be computed as the sum of capitalized EVAs or as the sum of uncapitalized SVAs....

The internal rate of return (IRR) is often used by managers and practitioners for investment decisions. Unfortunately, it has serious flaws: (i) multiple real-valued IRRs may arise, (ii) complex-valued IRRs may arise, (iii) the IRR is, in general, incompatible with the net present value (NPV) in...

Accounting measures are traditionally considered not significant from an economic point of view. In particular, accounting rates of return are often regarded economically meaningless or, at the very best, poor surrogates for the IRR, which is held to be “the” economic yield. Likewise,...

This paper shows that (i) project valuation via disequilibrium NPV+CAPM contradicts valuation via arbitrage pricing, (ii) standard CAPM-minded decision makers may fail to profit from arbitrage opportunities, (iii) standard CAPM-based valuation violates value additivity. As a consequence, the...

This paper uses counterexamples and simple formalization to show that the standard CAPM-based Net Present Value may not be used for investment valuations. The reason is that the standard CAPM-based capital budgeting criterion implies a notion of value which does not comply with the principle of...

This paper presents a new way of valuing firms and measuring residual income. The method, originally introduced in Magni (2000a, 2000b, 2000c, 2001), is here renamed lost-capital paradigm. In order to enhance comprehension the presentation relies on a very simple numerical example which shows...

This paper shows that a decision maker using the CAPM for valuing firms and making decisions may contradict Modigliani and Miller’s Proposition I, if he adopts the widely-accepted disequilibrium NPV. As a consequence, CAPM-minded agents employing this NPV are open to arbitrage losses and miss...
