This note specifies some results found in [Magni 2010. The Engineering Economists, 55(2), 150-180] where the Average Internal Rate of Return (AIRR) is presented, which overcome all the IRR difficulties. In particular, the AIRR approach enables to prove that (1) a project is not uniquely...

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,...

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

Abstract: In the standard Weighted Average Cost of Capital (WACC) applied to the free cash flow (FCF), we assume that the cost of debt is the market, unsubsidized rate. With debt at the market rate and perfect capital markets, debt only creates value in the presence of taxes through the tax...

In a forthcoming paper, Fernandez (2002) claims to derive a formula for the valuation of debt tax shields for firms with cash flows that grow perpetually at a constant rate. We show that his formula is incorrect and provide an example where his valuation would admit arbitrage.

We derive and present the formula for optimal debt under the assumption that tax shields are discounted at the cost of levered equity, Ke and cash flows are on perpetuity. The formulation is consistent and is derived from basic financial principles. This formulation is valid for non-growing...

In cash flow valuation (CFV), there are two main categories of mistakes: derivation of the appropriate cash flows and estimation of the cost of capital. A simple-minded view of the world would suggest that with near perfect capital markets, the presence of arbitrage would severely punish...

Se presenta la derivación de costo de capital bajo la premisa del ahorro deimpuestos de riesgo descuento con el costo de capital apalancado. Se demuestraque la formulación es coherente y se deriva de los principios financieros básicos. Esta formulación es válida para los flujos de caja...

This is a case for teaching. This case shows through several examples that the Net Present Value for project evaluation should be calculated based on estimates at current prices. It has been a widespread practice to evaluate projects at constant prices with a great deal of -today- unnecessary...
