Estimates of UK income inequality trends differ substantially according to whether estimates are based on household survey data (used for official statistics) or tax return data (used in the top incomes literature). We reconcile differences in variable definitions and combine survey and tax...

Atkinson, Piketty, and Saez (2011) survey an important new literature using income tax-based data to measure the share of income held by top income groups. But changes in tax legislation that expand the tax base to include income sources (e.g. capital gains, dividends, etc.) disproportionately...

Executors of estates for decedents in 2010 could choose between an estate tax regime and a basis carry-over regime. For most executors, this created a tradeoff between a current estate tax payment and a future capital gains tax liability for beneficiaries who inherited assets with...

We take stock of and compare tax revenue trends in Asia and Latin America. The tax revenues to GDP ratios increased significantly in both regions in the 2000s, although they remain visibly below European levels. Our analysis portrays a complex picture of the tax collection challenges facing...
