We investigate the effects of a Financial Transaction Tax (FTT) in an order-driven artificial financial market. FTTs are meant to limit short-term speculative behavior by reducing the amount of excess liquidity in the system. To quantify these effects, adjustments in trading strategies and their...

Die vorliegende Studie untersucht die Zusammenhänge zwischen Erdölpreisen, Kraftstoffpreisen, verbrauchten Mengen und dem Energiesteueraufkommen. Wesentliche Ergebnisse sind, dass die verbrauchten Kraftstoffmengen mit der gesamtwirtschaftlichen Produktion und den Erdölpreisen schwanken. Vor...

It is argued that the German system of supporting low wage income earners by government transfers gives incentives for employers and employees to contract low wages and then to exploit the government. The paper analyses if such incentives do exist. It turns out that this is the case under...

Based on a description of the German system of taxes and transfers, the incentives to work are analyzed for several groups of the labor force. The effects of the “Hartz IV” reform (effective from 2005 onwards) on the incentives receive particular attention. It turns out that the marginal...

The tax burden of typical wage income earners in Germany is analyzed. It turns out that the overall tax rate (wage income tax, solidarity surcharge, contributions to social security) for selected singles will go up in the period 2013–2017 if the tax rules will not be changed. The main reason...

The income tax rate structure introduced in 2007 was changed in 2009. The income tax rates will be lowered in 2010, too. The effects on the wage income tax revenues and on the incentives to work are analyzed. It turns out that “bracket creep” will remain a problem in Germany

The paper includes data on the taxation of wage income (labor income tax and contributions to social security) and capital income in the Federal Republic of Germany. Average tax rates and marginal tax rates for typical wage income earners are shown for the 1977–1999 period; average tax rates...

Tax expenditures are granted for a variety of purposes in Germany. They were significantly reduced in December 2003. After the general election in 2005, additional reductions of the tax expenditures were decided upon; however, new measures were introduced, too. The paper presents data on the...

Tax reform in Germany is proposed by political parties as well as by specific research groups. The gross wage income distributions for different groups of taxpayers are used to find out the consequences of introducing alternative rules of taxation for the wage income tax revenues. The results...

The gross wage income distributions for different groups of taxpayers in 1998 are used to derive wage income distributions for 2001–2006. By applying alternative rules of taxation, revenues according to different tax rate structures are deduced. Introducing new tax rates in 2004 resp. in 2005...
