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...

This paper introduces a new method of investment performance analysis, based on the recent approach of Average Internal Rate of Return (AIRR). We show that the approach generates rates of return suitable for assessing both a fund´s (portfolio´s) performance and a manager´s performance. The...

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 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...

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...

The purpose of this work is double. On one side, we wish to examine if subsidizing the cost of debt has some influence on the firm value (debt plus equity) or if it is just a transfer from debt holders to shareholders. On the other hand, we wish to show that research in Finance, as in many...

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...
