This teaching note shows the relationship between levered and unlevered betas and the general formulation for the cost of equity. It also shows, step by step, the procedure to estimate betas from data found in the stock market.It shows well known procedures for estimating betas: correlation...

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...

This paper presents a formal derivation of general expressions for Ke and WACC in perpetuities with constant growth, which do not make any assumption on what the proper discount rate is to be applied to the firm's tax shield, and are complemented with numerical examples of its application....

There are methods to match value added approaches (Residual Income Method, RIM and Economic Value Added, EVA) with discounted cash flow methods, DCF. In this note we use a real life case from an emerging country to illustrate the matching, with complexities such as unpaid taxes, losses carried...

Este trabajo muestra la relación entre las betas apalancadas y sin deuda y la formulación general para el costo del capital. También muestra, paso a paso, el procedimiento para calcular las betas a partir de los datos que se encuentran en el mercado de valores. Se muestran procedimientos...

This is a course material (slides in pdf format) for the chapter Financial Analysis and Control Financial Ratio Analysis already in SSRN. In these slides I present a detailed explanation of different financial ratios commonly used in financial management. We introduce some examples in the slides...

Llano-Ferro (2009) proposes a solution to avoid 'significant errors' when the Weighted Average Cost of Capital (WACC) obtained by the standard formula leads to significant errors in Net Present Value of the Firm calculations; particularly in those that apply to perpetual cash flow series. In...

Usually in financial textbooks and courses the theory of portfolio selection is taught in a strictly theoretical way. There is a model (Markowitz) that stipulates that an investor has preferences and that she will choose the best portfolio, given her preference curves and an efficient frontier....
