A nuestros estudiantes de Finanzas les enseñan que lo más importante en ese área es saber calcular y utilizar la tasa de interés efectiva o capitalizada. Para algunos de nuestros profesores, eso es todo; si un estudiante llega sin saber esa ficción, no sabe Finanzas. Más aun, una gran...

We examine the proper valuation of perpetuities without real growth. The case of a 'pure' non growing perpetuity (zero real growth and zero inflation) is of academic interest but in practice it might be difficult to find. The findings contradict what is generally accepted in the literature. In...

A typical approach for valuing finite cash flows is to assume that leverage is constant (usually as target leverage) and the cost of equity, Ke and the Weighted Average Cost of Capital, WACC are also assumed to be constant. For cash flows in perpetuity, and with the cost of debt, Kd as the...

Although we know there exists a simpleapproach to solve the circularitybetween value and the discount rate,known as the Adjusted Present Valueproposed by Myers, 1974, it seemsthat practitioners still rely on thetraditional Weighted Average Cost ofCapital, WACC approach of weightingthe cost of...

En este trabajo explicamos el uso apropiado de perpetuidades y el cálculo de su valor. Consideramos dos casos: calcular el valor en el período cero cuando la perpetuidad comienza con un flujo de caja dado en el período 1 y cuando se conoce el flujo de caja en el período cero y crece en el...

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...

Este es material de curso del libro Decisiones Empresariales bajo Riesgo e Incertidumbre. El nivel del libro es basico. Se usan muy pocas matematicas y puede ser usado por gerentes. El capitulo ocho estudia uno de los temas mas importantes de las finanzas corporativas: el costo promedio...

I present a set of conditions for defining risky debt associated to cash flow and not to accounting earnings. I explain why realization of tax shields for finite cash flows in any period of time t are correlated to Earnings before Interest and Taxes and are not correlated to interest expenses at...

When calculating Tax Savings, TS, we are confronted with a strange mix of accounting accrual and market value when involving TS in the calculation of the Weighted Average Cost of Capital, WACC, or the Cost of Equity, Ke. Firms earn the right to TS once they accrue the interest expense and they...
