    About Mercatus Regulatory Studies

    The Mercatus Center has developed several tools to help stakeholders analyze and critique proposed regulations and comment on them in a way that will make agencies more likely to respond. In addition to RegData, these tools include the Regulatory Cost Calculator, which helps stakeholders assess the prospective costs of new regulations proposed by agencies; Regulatory Report Cards, which identify the degree to which agencies follow best practices for regulatory analysis; and Mercatus public interest comments, which concisely critique the Regulatory Impact Analysis for many economically significant federal regulations.
