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...

This paper argues that increasing the GST, by raising the rate above 10 per cent while retaining the current tax base, or by broadening the base to include all forms of consumption expenditure, does not offer a solution to the widely perceived problems of the Australian tax system. The direct,...

This paper introduces a static structural model of hours of market labor supply, time spent on child care and other domestic work, and bought in child care for married or cohabiting mothers with pre-school age children. The father's behavior is taken as given. The main goal is to analyze the...

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...

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...

The Mirrlees Review of the UK tax system, together with its companion volume of research papers, can be expected to influence future discussions of tax reform. Indeed, this can already be recognised in the Henry Review. As far as income taxation is concerned, the most substantive recommendation...

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 an analysis of the 2005-06 family tax system comprising the personal income tax, the Medicare Levy, Family Tax Benefits Parts A and B and tax offsets. The results show that most families are now taxed, in effect, on the basis of joint income. Through a succession of reforms...

The tax policy agenda in Australia for more than a decade has been largely driven by a perceived need to reduce the level of income taxation and the progression of marginal rates, financing the revenue shortfall with a broad based consumption tax. A major reform of this kind is now being...
