Tax uncertainty often negatively affects investment. Advance tax rulings (ATRs) are commonly used as a measure to provide tax certainty. Rulings are currently controversially discussed in the context of tax planning activities of multinational firms (Luxembourg Leaks). We analyze ATRs as tax...

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...

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...

An investment that is characterized by exit flexibility requires both decisions on investment and holding period. As selling an investment often leads to tax-liable capital gains and capital gains crucially depend on the duration of an investment we investigate the impact of capital gains...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

This paper provides necessary and sufficient conditions for the existence of Pareto-improving tax reforms. The conditions can be expressed as sufficient statistics and have a wide range of potential applications in public finance. We discuss one such application in detail: the introduction of...

We present a conceptual framework for the analysis of politically feasible tax reforms. First, we prove a median voter theorem for monotonic reforms of non-linear tax systems. This yields a characterization of reforms that are preferred by a majority of individuals over the status quo and hence...

Der vorliegende Beitrag untersucht den Ein?uss der Besteuerung auf die Bereitschaft von Investoren, riskante und irreversible Investitionen durchzuführen. Als Erweiterung der vorliegenden Literatur wird ein einfaches Ertragsteuersystem in ein realoptionsbasiertes Modell irreversibler...

In this paper we analyze the impact of various minimum taxation concepts on corporate investment decisions. These investments can be realized in the form of either a real or a financial investment. In a quantitative analysis we refer to the future values of the investments as an indicator of...
