Template-type: ReDIF-Paper 1.0 Author-Name: Peichl, Andreas Title: Benefits and problems of linking micro and macro models – evidence from a flat tax analysis Abstract: The aim of this paper is to describe the state-of-the-art in simulation and to illustrate benefits and problems of linking micro and macro models by analysing flat tax proposals for Germany. The analysis shows that a personal income flat tax can indeed overcome the fundamental equity efficiency trade-off while simultaneously increasing the tax revenue. However, this result does not hold for a flat tax combining a personal income flat tax with a corporate cash flow flat tax, even when allowing for an ex-post loss in revenue as the top of the distribution still gains the most.
