We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is independent of the social welfare function and...

Considering a finance constrained economy, we discuss the stabilization role of variable labour and capital income taxes under a balanced-budget rule in the presence of consumption externalities of the "keeping up with the Joneses" type. We find that sufficiently procyclical labor and/or capital...

Within an efficiency wage framework, we study the effects of two revenue-neutral tax reforms that change the progressivity of the labour tax system. A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the...

In-work support through the tax-benefit system has proved to be an effective way of increasing labour supply of lone mothers and first earners in couples in a number of OECD countries. At the same time these instruments usually create negative employment incentives for secondary earners. This in...

The current Italian income support policies are defective with respect to both efficiency and equity. A more effective design must face five crucial choices: universal vs. categorical policies; transfers vs. subsidies; unconditional vs. means-tested policies; coverage; flat vs. progressive tax...

The individual voting behavior on the abolishment of single income-tax exemptions crucially depends on how strongly agents are affected by other deduction possibilities that are not at stake in the reform plans of the government. The interactions depend (i) on the shape of the tax schedule, and...

The purpose of SWEtaxben is to evaluate the impact of changes in the tax/benefit systems on households as well as the central governmental budget. Relating to the micro simulation literature this model can be labeled a static micro simulation model with behavioral changes. This behavioral change...
