The phenomenon of midnight regulations refers to the surge of regulatory activity at the end of every presidential administration. This surge often includes sweeping and controversial regulations that are hard to repeal once approved. During this period, the quality of the agencies’ regulatory analysis drops and regulatory oversight by the Office of Information and Regulatory Affairs (OIRA) weakens. This page aggregates Mercatus research on this topic as well as the supporting data from Mercatus Regulatory Report Cards.
