Proposals to expand tax-deferred savings accounts are generally estimated to result in a loss of tax revenue, according to models used by the U.S. Treasury and the Congressional Budget Office. In this seminar in AEI’s tax policy series, Professor Jonathan Skinner of Dartmouth College presents evidence suggesting the opposite, namely that individual retirement accounts have actually increased tax revenue. Professor Skinner attributes this result to a rising stock market, and he discusses whether similar behavior can be expected in the future. Jane Gravelle and Paul Burnham will comment on his presentation. A question and answer period will follow the presentations.
