In this paper we study the taxation of car ownership, car use and public transport in the presence of externalities within the framework of a discrete/continuous choice model. We first derive optimal taxes in a simplified setting, emphasizing the specific role of fixed car ownership taxes and...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

We provide a welfare based interpretation of the capital tax ambiguity result (due to Guo & Lansing, 1999). We show that the sign ambiguity of optimal capital tax rate in an imperfectly competitive economy is mainly due to the welfare cost of investment. The substitution and income effects of...

The purpose of this paper is to present an exercise where we identify optimal income tax rules according to various social welfare criteria, keeping fixed the total net tax revenue. To this end, we estimate a microeconomic model with 78 parameters that capture heterogeneity in...

The purpose of this paper is to present an exercise where we identify optimal income tax rules under the constraint of fixed tax revenue. To this end, we estimate a microeconomic model with 78 parameters that capture heterogeneity in consumption-leisure preferences for singles and couples as...
