Applying benefit-cost analysis in the White House regulatory oversight process served as a basic mission of the Council on Wage and Price Stability (CWPS) during its seven-year lifespan (1974–1981). This paper reviews that CWPS experience, which involved filing comments in over 300 proceedings at more than 25 federal regulatory agencies. The paper draws on those CWPS public comments (filings), identifying persistent and pervasive deficiencies in the economic analysis regulators then and now often use as support for new regulation. CWPS filings fostered greater acceptance of benefit-cost analysis in regulatory decisions; such analysis is now required by executive order.
