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...

The internal rate of return (IRR) and the corresponding criterion has well-known difficulties of applicability and reliability. Among other problems, a project may have no real-valued IRR. The latter problem has been recently solved by Magni (2010a), who shows that, for any project, a unique...

This paper shows how to proceed to find the optimal capital structure and value with period-to-period constant and variable leverage, when the discount rate for tax shields is Ke, the cost of levered equity. Numerical procedures and recursive closed-form non-circular expressions for the...

The internal rate of return (IRR) is used extensively in the real estate sector, notwithstanding certain nagging deficiencies taught in most business school texts, such as that the IRR may have multiple solutions which cannot be reconciled; or that it may lead to decisions that are not consistent...

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...

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...

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...
