In many industries like management consulting, IT consulting, or construction highly qualified employees, i.e., experts or executive managers, have to be assigned to temporary projects. In firms with many employees and various different projects, this assignment decision involves a complex...

The introduction of a common consolidated corporate tax base (CCCTB) and tax allocation via formula apportionment (FA) is hotly debated in the European Union (EU) since more than a decade. While the literature has thoroughly analyzed the economic effects of FA from a macro-level perspective, the...

We examine the combined effects of asymmetric taxation and limited liability on optimal risk taking of investors. Given an optimal risk level in the pre-tax case under full liability, loss-offset restrictions reduce, and limited liability enhances the incentives for taking risk. For every degree...

This paper analyzes the effects of symmetric and asymmetric taxation on performance-based versus fixed remuneration contracts. I integrate a proportional corporation tax and a proportional wage tax into a binary principal-agent model. The wage tax increases the remuneration costs and makes the...

We derive determinants of tax avoidance by means of a multi-task principal-agent model. We extend prevailing models by integrating both corporate and individual income taxation as well as by including tax planning effort in the agent’s action portfolio. Our model shows novel and apparently...

This paper deals with the effects of tax rate uncertainty on risk-neutral and risk-averse investment behavior. We analyze effects of stochastic tax rates on both real and financial investment. It emerges that under risk neutrality as well as under risk aversion, increased tax rate uncertainty...

In recent years stock option plans (SOPs) have become an important component of managerial remuneration in most industrialized countries. Commonly accepted, corporate as well as individual taxes have a major impact on the costs of a SOP. In contrast, the tax influence on the benefits of a SOP...

Tax legislation, fiscal authorities, and tax courts create tax uncertainty by frequent tax reforms and various different interpretations of the tax law. Moreover, investors generate model-specific tax uncertainty by using simplified models that anticipate the actual tax base incorrectly. I...

This paper analyzes the impact of particular loss offset limitations on intrastate and cross-border investment decisions. Investment can be realized in the investor’s domestic business, in a foreign branch or in a foreign subsidiary. The relative impact on the optimal real investment...

For mitigating the problems of transfer pricing formula apportionment (FA) is discussed intensively. However, FA could even be more harmful than transfer pricing because income shifting would require changing economic decisions instead of just taking advantage of accounting options. We analyze...
