This paper shows that the notion of rate of return is best understood through the lens of the average-internal-rate-of-return (AIRR) model, first introduced in Magni (2010a). It is an NPV-consistent approach based on a coherent definition of rate of return and on the notion of Chisini mean, it...

In this note we make use of theAverage Internal Rate of Return (AIRR) approach, first introduced in Magni (2010), to introduce a pair of metrics, opposed to IRR and TWRR, which measure the manager's performance and the investor's performance on the basis of the market values of the fund. We also...

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

Italian Abstract: Questo pamphlet è un breviario di sopravvivenza intellettuale per difendersi dalla disinformazione e dal mito dell'Euro. Il disegno dell'Eurozona si fonda su un'architettura economica irrazionale derivata da principi di liberismo economico che da più trent'anni sono egemonici...

This paper focuses on inconsistencies arising from the use of NPV and CAPM for capital budgeting. It shows that (i) CAPM capital budgeting decision-making based on disequilibrium NPV is deductively inferred by the Capital Asset Pricing Model, (ii) the use of the disequilibrium NPV is widespread...

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...

This paper introduces a new method of investment performance analysis, based on the recent approach of Average Internal Rate of Return (AIRR). We show that the approach generates rates of return suitable for assessing both a fund´s (portfolio´s) performance and a manager´s performance. The...

Questo articolo si propone di dimostrare che il ROE (Return On Equity) ha un significato economico pregnante, al contrario di quanto sostenuto nella letteratura finanziaria e manageriale, nonché nella prassi aziendale. In particolare, un´opportuna media dei ROE è in grado di segnalare la...

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...
