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...

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 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...

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...

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...

The traditional literature on the CAPM assumes that investor's tax payments simply vanish from the model. This assumption is not at all consistent with the actual behavior of the Treasury. The theory of general equilibrium states that an interest rate rf = 0 will not affect prices if taxes are...

Zuweilen wird die Meinung vertreten, dass es Investoren um jeden Preis vermeiden sollten, Steuern zu zahlen. Im Rahmen eines einfachen Portfoliomodells mit Steuern wird untersucht, ob Steuervermeidung tatsächlich auf μ-σ2-effiziente Lösungen führt. Für vier verschiedene Konzepte der...
