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...

We provide a critique of the standard methodology which bases welfare comparisons between households on deflating household income and consumption by an equivalence scale. We argue that this leads to support for tax/transfer policies that significantly disadvantage low to middle in-come...

Transferring public benefits to people in no need of them appears to be a waste of public money. Thus, there seems to be support for a move away from universal child benefits and towards means testing. This study presents a critique of this overly-simplistic view and proposes a very simple...

Given its significance in practice, the piecewise linear tax system seems to have received disproportionately little attention in the literature on optimal income taxation. This paper offers a simple and transparent analysis of its main characteristics. -- Piecewise linear ; income ; taxation

This paper presents the properties of optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction between second earner wage differences, variation in the price of child care and...
