Germany is in a dilemma. Low wage competition via product and factor markets increases the demands on the welfare state, but increased systems competition in the context of international factor mobility reduces the possibilities of maintaining it. The welfare state has important allocative...

Several recent studies suggest that equalizing transfers in a federal system may distort the tax policy decisions of states. We study this issue for the German federal fiscal system.

Gas exports to the Continent are regulated by long term take-or-pay contracts. The contracts are described and analyzed.
