The conventional approach to modelling family labour supply is to estimate a system of two-adult equations on micro data sets providing information on female and male hours of market work and aggregate family consumption of market goods. Information on all individual consumptions, including pure...

Household labour supply models are typically estimated on data sets containing information on family consumption and male and female hours of market work. The estimating equations are consistent with a theoretical model which assumes the maximisation of a household utility function defined on...

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...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

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...

This paper is a survey of the literature on theoretical models of the household, paying particular attention to some of the earlier contributions, and using them to place the current state of the theory in perspective. One of its aims is to suggest that the literature’s neglect of...

In many countries, fears that genetic testing may lead to a "genetic underclass" have led to restrictions on insurance companies' access to genetic information. This paper first shows that such restrictions are Pareto inefficient. The real problem appears to be that in the absence of such...
