This paper presents the properties of optimal piecewise linear income tax systems for families based on joint and individual incomes respectively. It models the interaction between the wage rates of mothers as "second earners" and variation in child care prices and productivities as determinants...

This paper analyses optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. It models the interaction between wage rates and variation in child care prices and productivities as determinants of across-household heterogeneity in second...

In this paper, we analyze how top income earners (TIEs) respond to changes in personalincome taxation. Our identification strategy exploits a unique reform to Uruguay’s progressivelabor income tax schedule that affected differently the tax rates of taxpayers within the top 1%of the labor...

The adverse distributional effects of a flat tax are well known and have been documented by empirical research in several countries, including Belgium. Advocates of the flat tax argue, correctly, that many of these studies do not take into account agents' behavioural reactions and possible feed...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

Two traditional options for reforming Ehegattensplitting, the joint taxation of married couples with full income splitting, are de facto income splitting (Realsplitting) or individual taxation with a transferable personal allowance. However, these proposals do not significantly reduce the...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

Low labour market participation, together with the high effective tax wedge at low wage levels, create a fertile ground for the introduction of the in-work benefits (IWB) in Serbia. Our paper provides an ex-ante evaluation of the two IWB schemes, directed at stimulating the labour supply and...

We study the elasticity of taxable labour income in the Netherlands. We use a large and rich data set, including both financial and demographic variables, for the period 1999-2005. The 2001 tax reform generates large exogenous variation in marginal tax rates at different segments of the income...

Die Wahl des Spitzensteuersatzes wird seit jeher strittig diskutiert. Auch in Deutsch-land hat sich im derzeitigen Bundestagswahlkampf die Diskussion um einen höheren Spitzensteuersatz zu einem der zentralen Wahlkampfthemen entwickelt. Unter Verwendung administrativer Einkommenssteuerdaten...
