Zentraler Gegenstand der Arbeit sind die Steuerwirkungslehre sowie deren allokationstheoretischen Grundlagen und Implikationen. Auf der Basis eines allgemeinen Gleichgewichtsmodells werden die Auswirkungen unterschiedlicher Formen der Besteuerung auf die Ressourcen- und Einkommensverteilung...

This paper analyses the implications of a currently publicly debated issue, namely the introduction of a bonus tax. We shed light on the effects of the bonus tax on compensation components and study its incidence. We use the Principal Agent model within a two-country framework and consider two...

When we analyse the labour market consequences of labour tax reforms in a model of firm-union wage bargaining, minor changes in the formulation of the union's fallback option can have drastic effects. This paper compares two variants of the model in which either workers have no reemployment...

We present an applied general equilibrium modelling approach to analyse employment and unemployment effects of labour tax cuts in an economy where wages are determined through firm-union bargaining at the sectoral level. In such a labour market regime, simulations for Germany show that labour...

Many developing countries have introduced sector-specific taxes on the consumption of mobile services, which apply on top of general taxes, and therefore discourage the positive externalities that have been estimated to be associated with the use of mobile technology on workers' productivity and...

We study the optimal tax system when taxpayers earn different kinds of income by supplying different inputs. Imperfect substitution between inputs allows for general equilibrium effects. We consider any type of cross-base responses to tax changes such as income-shifting. Formalizing the tax...
