Final versions all to appear on the Mirrlees webpage at IFS within the next week or so What of the Review Recommendations? Based on lessons from new developments in theory Optimal tax Dynamic fiscal policy Behavioural economics Political economy Founded on what we have learned from empirical

analysis Labour supply Savings Taxable income Corporate investment and R&D Drawing on what we have learned from policy experience Theory, Policy and Data Interactive - theory often lags policy initiatives and

the discovery of empirical regularities; e.g. Earned income tax credits (WFTC and WTC) Policy developed in 70s and 80s. Empirics on extensive elasticity for low skill workers in 80s and 90s Optimal tax foundations developed in 2000+! But feedback in to policy improvements? Asset tests or similar conditions on eligibility to welfare benefits incapacity and disability Optimal dynamic fiscal policy in the last few years points to the potential optimality of asset tests. Optimal tax provides a logical framework Neutrality remains a central theme

Across assets Across goods Across time Across organisation form, location, . Distortions are inevitable but We know better how and where these should occur Each has to be argued strongly and needs to pass the political economy, transparency, salience and implementability test The expenditure tax ideas of the Meade Report

remain a powerful organising principle Special Session: The Mirrlees Review Reforming the Tax System for the 21st Century Stuart Adam (IFS): The Design of Household Taxes Steve Bond (Oxford & IFS): The Taxation of Companies Paul Johnson (IFS & Frontier): Making Change Happen Royal Economic Society March 17th 2008 http://www.ifs.org.uk/mirrleesreview
