This paper deals with the problem of modelling in a formal way the concept of excess profit, also known as residual income. A common idea is that excess profit is an unequivocal concept, being the diference between profit and costs, where all types of costs are taken into account, included the...

In Magni [Eur. J. Operat. Res. 137 (2002) 206] I present some inconsistencies implicit in the net-present-value criterion, as currently used in finance. This paper shows that the standard use of CAPM for capital budgeting, based on disequilibrium values, is at odds with arbitrage theory, and...

This paper presents a new approach to real options. The current options-based models have provided new insights into capital-budgeting decisions. Unfortunately they are not widely used by corporate managers and practitioners as they are formally complex, rather difficult to understand and rest...

This paper analyzes the relations among different concepts such as earnings, profit, interest, rate, consumption, dividend, installment, cash flow, capital. It aims atembracing these notions in a unique conceptual "umbrella" , consisting of five perspectives: (1) accounting, (2) economic theory,...

Two measures of excess profit (residual income) are currently available in the literature: the standard one, of which Economic Value Added (EVA) (Stewart, 1991) is a major instantiation, and Systemic Value Added (SVA) (Magni, 2003, 2004, 2005), also named lost-capital residual income (Magni,...

Il presente lavoro tratta del classico criterio di capital budgeting derivato dal CAPM, secondo il quale un investimento è conveniente se e solo se il suo tasso di rendimento atteso è maggiore del costo del capitale. Tale criterio è esposto, tra gli altri, da Rubinstein (1973) ed è...

Practitioners and some academics use potential dividends rather than actual payments to shareholders for valuing a firm’s equity. We underline the differences between the two methods and present some arguments supporting the thesis that firm valuation with potential dividends overstate the...

Practitioners and academics in valuation include changes in liquid assets (potential dividends) in the cash flows. This widespread and wrong practice is inconsistent with basic finance theory. We present economic, theoretical, and empirical arguments to support the thesis. Economic arguments...

This paper shows that the Internal-Rate-of-Return (IRR) approach is unreliable, and that the recently introduced Average-Internal-Rate-of-Return (AIRR) model constitutes the basis for an alternative theoretical paradigm of rate of return. To this end, we divide the paper into two parts: a pars...

The internal rate of return (IRR) is a widely used benchmark for assessing the reliability of the accounting rate of return (ROA) as a measure of economic profitability. We turn this reasoning process on its head by demonstrating that a suitable (weighted average) aggregation of ROAs better...
