The Urban-Brookings Tax Policy Center, American Tax Policy Institute, and Tax Analysts cosponsored a conference entitled Taxing Capital Income: Do we? Should we? Can we? (Can we not?). The one-day conference brought together leading economists, lawyers and accountants from across the political spectrum to discuss issues surrounding the choice of income or consumption as a tax base. Sessions addressed each question in the title. Douglas Holtz-Eakin, Director of the Congressional Budget Office, presented the luncheon address, and a wrap-up panel featured Henry Aaron, Leonard Burman and Dan Halperin. Drafts of the conference papers are available at the ATPI website, http://www.americantaxpolicyinstitute.org/.
