Deregulation has been a centerpiece of the Trump Administration’s agenda. One of the key initiatives that the Administration has used to attempt to advance deregulation is a regulatory budget. Modeled on ideas that have percolated in the academic literature for more than a generation, a regulatory budget puts a limit on the costs that agencies such as the Environmental Protection Agency and the Department of Homeland Security can impose on the public through regulation.
Executive Order 13771 outlines the details of the Trump Administration regulatory budget. The Order states, “all agencies are directed that the total incremental cost of all new regulations, including repealed regulations, to be finalized this year shall be no greater than zero, unless otherwise required by law.” The Office of Information and Regulatory Affairs (OIRA) later produced guidance on agency compliance with the regulatory budget and has since worked with agencies to develop annual regulatory budgets.
