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 income...

Given its significance in practice, piecewise linear taxation has received relatively little attention in the literature. This paper offers a simple and transparent analysis of its main characteristics. We fully characterize optimal tax parameters for the cases in which budget sets are convex...

We set out a general framework for cooperative household models, based on Samuelson's idea of a household welfare function, but extending it to incorporate the key insight from Nash bargaining models - the idea that the household's preference ordering over the utility profiles of its members...

The existing literature suggests that when the saving decision of two-earner households under risk is analysed, standard results on the existence of precautionary saving no longer apply: precautionary saving is obtained if and only if very stringent conditions hold. This paper shows that when...

This paper presents for the first time 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 of second earner wage differences, variation in prices of bought-in...
