The recent notion of Average Internal Rate of Return (AIRR) [Magni 2010, The Engineering Economist, 55(2), 150-180] completely solves the long-standing problem of the internal rate of return (IRR). While the AIRR is a return measure, this paper presents a cash-flow measure, namely the ratio of...

This paper analyzes the net-present-value (NPV) model, a keystone in economics: Behaviors and lines of reasoning of NPV-minded decision makers are observed and analyzed. As a result, one finds out that the NPV methodology is biased and its decision makers fall prey to various forms of fallacies...

This paper proposes a method for evaluating a project under certainty by means of a systemic outlook, which borrows from accounting the way of representing economic facts while replacing accounting values with cash values. The investor's net worth is regarded as a system whose structure changes...

This paper generalizes Makeham’s formula, allowing for varying interest rates and for a non-flat structure of valuation rates. An average interest rate (AIR) is introduced, as well as an average valuation rate (AVR), which exist and are unique for any asset. They can be computed either as...

This paper aims to provide a foundation for the notion of economic rate of return and investigate its relations with accounting rates of return. Introducing the notion of depreciation class (the set of depreciation schedules with the same aggregate book value) it is shown that the mean of the...

Evaluating an industrial opportunity often means to engage in financial modelling which results in estimation of a large amount of economic and accounting data, which are then gathered in an economically rational framework: the pro forma financial statements. While the standard net present value...

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...

Residual income as commonly described in academic papers and in real-life applications may be formally described as a function of three variables: (i) the capital invested, (ii) the rate of return, (iii) the opportunity cost of capital. This paper shows that a different paradigm of residual...

This paper deals with with capital budgeting decisions under uncertainty. We present an Aggregate Return On Investment (AROI), obtained as the ratio of total (undiscounted) cash flow to total invested capital and show that it is a genuine rate of return which, compared with the risk-adjusted...

This paper deals with the CAPM-derived capital budgeting criterion, and in particular with Rubinstein’s (1973) criterion, according to which a project is profitable if the project rate of return is greater than the risk-adjusted cost of capital, where the latter depends on the project’s...
