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...

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...

Prior to the last three decades, regular surveys on household income were rare or non-existent in many developed countries, making it difficult for economists to develop long-run series on income distribution. Using taxation statistics, which tend to be available over a longer time span, I...
