Tax saving´s valuation is crucial for discounted cash flow valuation and WACC estimation. There is an ongoing debate about the appropriate discount rate for tax savings under CAPM approach. On this paper we evaluate tax savings from a contingent claim approach in order to establish a framework...

In investment appraisal, uncertainty can be managed through intervals or fuzzy numbers because the arithmetical properties and the extension principle are well established and can be successfully applied in a rigorous way. We apply interval and fuzzy numbers to the Average Internal Rate of...

This paper expands Teichroew, Robichek and Montalbano's (TRM) (1965a, b) rate-of-return model into a complete and general model of economic profitability for investment decision-making. Specifically, TRM's assumptions are relaxed and a project rate of return is derived, expressing the project's...

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...

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 article explores the behavior of the stock market in Colombia with the information given by the Bolsa de Bogota Index (Indice de la Bolsa de Bogota, IBB). The index is analyzed from January, 1930 to December, 1998. The inflation rate covers the same period; the inflation rate as measured by...

This paper shows a formulation for the cost of equity and the WACC for growing perpetuities. Some authors have derived the general expressions for those formulas but not specifically for perpetuities with constant growth. The result obtained is that a previously general formulation for a finite...

Los ahorros en impuestos por deuda son un tema de obligado interés dentro de la literatura financiera porque desafían el supuesto de que la deuda destruye valor, al demostrar que genera subsidios de impuestos que representan valor para las compañías. Pocos son los estudios empíricos que se...

En Vélez-Pareja y Tham (2001), presentamos diferentes maneras de valorar los flujos de caja. Primero se utilizó el costo promedio ponderado de capital (CPPC) (Weighted Average Cost of Capital, WACC) para descontar el flujo de caja libre (FCL). Segundo, se descontó el FCL con el WACC ajustado....
