If one wants to evaluate the impact of an income tax on the value of a project or a firm the so called standard model of Johannson is usually applied. One important feature of this model is that the cost of capital are multiplied by a factor (1-s) where s is the income tax rate (assumed to be...

In this paper we consider firms having pension and other non-tradeable liabilities and we ask whether the methods of discounted cash flow (DCF) can be used for evaluation of the company. This question was so far not discussed in the literature systematically. We show how balance sheet are to be...

For the valuation of a company it is necessary to take the in come tax of its owners into account. When looking at a squeeze-out with investors who have different wealth this implies that fair compensation payments will be different. This is in contradiction to the German Stock Companies Act. In...

We generalize the classical concept of a certainty equivalent to a model where an investor can trade on a capital market with several future trading dates. We show that if a riskless asset is traded and the investor has a CARA utility then our generalized certainty equivalent can be evaluated...

A simple counterexample shows the the widely used WACC approach to value leverage firms developed by Miles and Ezzell can create an arbitrage opportunity. The only consequence to be drawn is that their WACC approach cannot be applied under the circumstances assumed by Miles and Ezzell. We show...

In capital budgeting problems future cash flows are discounted using the expected one period returns of the investment. In this paper we establish a theory that relates this approach to the assumption that markets are free of arbitrage. Our goal is to uncover implicit assumptions on the set of...

We extend the WACC approach to a tax system having a firm income tax and a personal income tax of the investor as well. We use an artificial tax system incorporating most of the G-7 national tax codes as for example the classical or the imputation systems. On our website (www.wacc.de) WACC...
