Observed fiscal policy varies greatly across time and countries. How can we explain this variation? This paper surveys the recent literature that has tried to answer this question. We adopt a unified approach in portraying public policy as the equilibrium outcome of an explicitly specified...

This paper investigates the distributional and efficiency implications of a tax-mix change involving a reduction in personal income taxation financed by a board based consumption tax.

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...

This paper considers more major structural reforms which could address such problems in a systematic manner, and allow the implementation of a designed set of effective tax rates (ETRs) for social security clients and taxpayers.

This paper considers options for addressing problems in the way the tax and social security systems interact.

This paper considers how asymmetric tax treatment, where labour market earnings are taxed but household production is untaxed, aspects educational choice and labour supply. We show that taxes on labour market earnings can generate a large (non-marginal) switch to home production and the ensuing...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...

We develop a framework for optimal taxation when agents can earn their income both in traditional activities, where private and social products coincide, and in rent-seeking activities, where private returns exceed social returns either because they involve the capture of pre-existing rents or...
