Universal acclaim rarely comes to a theorist who tries to implement his ideas. As administrator of the White House Office of Information and Regulatory Affairs, he reviewed the rules implementing President Obama’s health care act and the Dodd-Frank financial regulatory reform law. He backed major environmental initiatives, including higher fuel efficiency standards for cars and trucks and new toxic emissions rules for power plants. He approved the revamping of the decades-old food pyramid (it is now a “plate”), the tightening of salmonella rules for eggs and a crackdown on prison rape. He midwifed a deal between appliance manufacturers and the Department of Energy to make refrigerators more energy efficient.
