We analyze optimal income taxes with deductions for work-related or consumptive goods. We consider two cases. In the first case (called a complex tax system) the tax authorities can exactly distinguish between consumptive and work-related expenditures. In the second case (called a simple tax...

In der Literatur ist seit langem bekannt, wie man Ertragsteuern in die Unternehmensbewertung einzubeziehen hat. In dieser Arbeit klären wir, wie man ein Unternehmen bewertet, dessen Eigentümer eine Erbschaftund Schenkungsteuer zu leisten haben.

We look at the theory of arbitrage with taxation under certainty. The tax scale in our model is not linear. Under the premise that tax scale is convex, we analyze prices that do not exhibit arbitrage opportunities. It turns out that there are two kinds of arbitrage: unbounded as well as bounded...

Risk aversion in game theory is usually modeled using expected utility, which was criticized early on, leading to an extensive literature on generalized expected utility. In this paper we are the first to apply μ-σ theory to the analysis of (static) games. μ-σ theory is widely...

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 the standard CAPM with a riskless asset we prove existence of equilibria without assuming concavity of the investor's utility functions. Moreover, we give a uniqueness result using assumptions on the risk aversion of investors.

The best way to improve daylight performance is to take a closer look on the behaviour of lighting the interior of sample building spaces. Scale models are commonly used to assess daylighting performance of buildings using an artificial sky for purpose of research and teaching as well as...
