Tax uncertainty often negatively affects investment. Advance tax rulings (ATRs) are commonly used to provide tax certainty. We analyze ATRs from the taxpayers' and tax authorities' perspectives. Investors request ATRs if the fee does not exceed a certain threshold. We integrate this finding into...

Politicians and tax practitioners often claim that tax uncertainty negatively affects investment. In many countries, firms can request fee-based Advance Tax Rulings (ATRs) to mitigate tax uncertainty. We analyze theoretically the circumstances under which investors request ATRs, how tax...

The discussion about income versus consumption as the ideal tax base looks backon a long history. In recent years, the debate about income versus consumption as the bettertax base reemerged in the United States (2002) and in Germany (2006). In view of the longhistory of the debate, it is...

Kapitalmarktorientierte Unternehmen in Deutschland orientieren sich in zunehmendem Maße an der Konzernsteuerquote. Diese unterscheidet sich in wesentlichen Aspekten von den in der Forschung gängigen Maßen der effektiven Besteuerung, die auf dem neoklassischen Investitionsmodell basieren. Dies...

Effective tax rates (ETRs) are designed to indicate the influence of taxes on investments. Existing ETR models fail to generate ETRs that can be compared to a constant yardstick and to other ETRs. This paper develops a new ETR approach based on neutral tax systems. Integration of neutral...

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...

It is well-known that taxes affect risky investment decisions. Analytical studies indicate that tax rate increases can foster (accelerate) investment if there is flexibility, in particular when an exit option is available. We design an experiment that is based on an analytical model with...

Tax uncertainty is often claimed to be harmful for investments. Capital taxes, such as property and wealth taxes, are particularly exposed to tax uncertainty. Capital tax un- certainty emerges from expected tax reforms, the unclear outcome of future tax audits, and simplified estimates of...
