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...

This paper presents a formulation for the cost of equity, the WACC, and the value of equity and firm for growing perpetuities without circularity, using some previous results. We also derive a relationship between leverage, D%, and growth, given a value of debt at instant zero.

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, residual...

The IRR problem. As widely known, the IRR has serious flaws: (i)multiple real-valued IRRs may arise, (ii) the meaning of each IRR may be ambiguous (rate of return or rate of cost?), (iii)complex-valued IRRs may arise, (iv) the IRR is, in general, incompatible with the net present value (NPV) in...

Vélez-Pareja and Tham, 2003a, Vélez-Pareja and Tham, 2003b and Tham and Vélez-Pareja, 2004 showed the matching between discounted cash flow (DCF) methods and value added methods. They departed from the net operating profit less adjusted taxes NOPLAT and net income when using market values to...

Usualmente los textos de finanzas presentan por lo menos un capítulo sobre análisis financiero, entendido como análisis de razones financieras. Se enseñan muchos cursos en análisis financiero y se gasta una enorme cantidad de tiempo en cómo calcular las razones financieras basados en...

cash flow and time value of money. In this note we specify very clearly what has to be included in those cash flows and the reasons why they should be included. The main issue is related to the inclusion or exclusion of some items in the working capital and the current practice to consider that...

We present the derivation of cost of capital under the assumption of risky tax shields discounted with the cost of levered equity. We show that the formulation is consistent and is derived from basic financial principles. This formulation is valid for finite cash flows and non growing...

En Vélez-Pareja y Tham (2003), se presentó la forma de hacer coincidir los métodos de valor agregado (utilidad económica (UE) (Residual Income Method, RIM) y el valor económico agregado (VEA) (Economic Value Added, EVA)) y los métodos de flujo de caja descontado (discounted cash flow,...
