I review 150 textbooks on corporate finance and valuation published between 1979 and 2009 by authors such as Brealey, Myers, Copeland, Damodaran, Merton, Ross, Bruner, Bodie, Penman, and Arzac, and find that their recommendations regarding the equity premium range from 3% to 10%, and that 51...

The document starts with 100 questions that students, alumni and other persons (judges, arbitrageurs, clients…) have posed to me over the past years. They were recompiled so as to help the reader remember, clarify and, in some cases, discuss some useful concepts in finance. Most of the...

In this paper, we quantify shareholder value creation for 276 American companies. We provide the created shareholder value for each and every company for years 1998, 1999, 2000 and 2001. The market value of the 276 companies was 8,716 billion dollars in 2001 and 9,729 billion dollars in 2000. We...

In this paper, we quantify shareholder value creation for 274 American companies. We provide the created shareholder value for each and every company for years 1998, 1999, 2000 as well as for 1993-2000. The market value of the 274 companies was 9,680 billion dollars.We define created shareholder...

We value a company that targets its capital structure in book-value terms. This capital structure definition provides us with a Value of Tax Shields that lies between those of Modigliani-Miller (fixed debt) and Miles-Ezzell (fixed market-value leverage ratio). If a company targets its leverage...

This paper corrects some equations of Farber, Gillet and Szafarz (2006). The WACC is a discount rate widely used in corporate finance. However, the correct calculation of the WACC rests on a correct valuation of the tax shields. The value of tax shields depends on the debt policy of the company....

We develop valuation formulae for a company that maintains a fixed book-value leverage ratio and claim that it is more realistic than to assume, as Miles-Ezzell (1980), a fixed market-value leverage ratio. The value of tax shields depends only on the present value of the net increases of debt....

The value of tax shields depends only on the nature of the stochastic process of the net increases of debt. The value of tax shields in a world with no leverage cost is the tax rate times the current debt plus the present value of the net increases of debt. By applying this formula to specific...
