The Hutchins Center Explains: Dynamic Scoring


A recent change to House rules requires the Joint Tax Committee (JCT) and the Congressional Budget Office (CBO) to use dynamic scoring—the practice of taking account for macro-economic effects—in calculating the official price-tag for certain major tax and spending bills.

To move beyond the debate over whether this is wise, and shed light on the way these important estimates are made, the Urban-Brookings Tax Policy Center and the Hutchins Center on Fiscal and Monetary Policy at Brookings will sponsor Dynamic Scoring: Now What? on Monday, Jan. 26. The event will feature, among other things, a presentation by JCT staffers on how they evaluated a recent major tax-reform proposal by former Rep. Dave Camp (R., Mich.) and responses by experts of different viewpoints as well as a panel on dynamic scoring of immigration, health-care, infrastructure, fiscal-stimulus and other non-tax legislations.

Below is a reading list of some of the recent congressional staff discussions of the issues surrounding dynamic scoring, and commentary by some of the panelists who will be at the January 26 event.
