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...

While acknowledging the importance of fairness and the need to avoid creating disincentives in the design of tax reform, the Henry Review recommends a simplified Personal Income Tax and child payments withdrawn on a single family income test. This paper shows that the proposed reforms would...

This paper focuses on a 1999 reform to the UK tax credit system, which increased the value of the credit and reduced the...

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...

We examine the case for maintaining welfare and income redistribution programs even when their adverse general equilibrium effects reduce total earnings of poor households. Using a Cournot model of intra-household decision-making, we show that even if welfare cutbacks generate large increases in...

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...

The Fukushima disaster has lead the French government to release novel cost information relative to its nuclear electricity program allowing us to compute a levelized cost. We identify a modest escalation of capital cost and a larger than expected operational cost. Under the best scenario, the...

In the early 1980’s Australia had a highly progressive, individual based income tax and families received support for dependent children in the form of universal family allowances. The introduction of income tests for child support payments based on family income (now in the form of Family Tax...

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...
