This paper presents for the .rst time the properties of optimal piece-wise 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 di¤erences, variation in prices of bought-in...

Given its signiÖcance in practice, piecewise linear taxation has received relatively little attention in the literature. This paper o§ers 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 show that measurement error in the constructed price of child care can explain why previous Australian studies have found partnered women’s labour supply to be unresponsive to child care prices. Through improved data and improved construction of the child care price variable, we find child...

The supply of formal childcare has expanded in many developed countries. There is ambiguity, however, in the theory that the entry of care providers increases consumers’ surplus and the welfare of households in a market with differentiated services, such as childcare. This study empirically...

Do income taxes levied at a state or regional level affect the after-tax distribution of income? Or do workers merely move between regions, causing pre-tax wages to adjust? This question is relevant both in across states in the United States, and across countries within the European Union. Using...
