Die Steuerplanung internationaler Unternehmen, die durch geschickte Kombination von Regelungen ihre Steuerbelastungen gegen null senken, und die Steuerpolitik einiger Länder stehen in der öffentlichen Kritik. Johanna Hey, Universität zu Köln, verweist darauf, dass es bei der Bekämpfung sog....

We characterize the Pareto-frontier in a simple Mirrleesian model of income taxation. We show how the second-best frontier which incorporates incentive constraints due to private information on productive abilities relates to the first-best frontier which takes only resource constraints into...

This paper studies the impact of a financial transactions tax on a financial market where financial institutions trade with each other. Assets are marked to the market and financial institutions with negative equity are forced out of business. There are two main results: First, if all banks have...

This paper derives a version of the Samuelson rule which takes into account that a distortionary Ramsey-tax system is used to finance public-goods provision. Individuals have private information about their public-goods preferences. Moreover, individuals differ in their productive abilities. The...

We propose a new approach to the normative analysis of public-good provision. In addition to individual incentive compatibility, we impose conditions of robust implementability and coalition proofness. Under these additional conditions, participants' contributions can only depend on the level of...

We study the provision of public goods. Different public goods can be bundled provided there is enough capacity, i.e. resources to pay for all the public goods in the bundle. The analysis focuses on the all-or-nothing-mechanism: Expand provision as much as resource feasible if no one vetoes -...

We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or...

We study a large economy model in which individuals have private information about their productive abilities and their preferences. Moreover, there is aggregate uncertainty so that the social benefits from taxation and public goods provision are a priori unknown. The analysis is based on a...

This paper extends the model of optimal income taxation due to Mirrlees (Mirrlees, J., 1971. An exploration in the theory of optimum income taxation. Review of Economic Studies 38, 175-208) and includes private information on public goods preferences. A mechanism design approach is used to...

The literature on public goods has shown that e?cient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions e?ciency considerations justify that individuals are forced to pay for...
