Yesterday, the White House officially nominated law professor Cass Sunstein to head the Office of Information and Regulatory Affairs. Sunstein will be charged with overseeing everything from economic to environmental to health regulation, and he will also be tasked with monitoring government efficiency.

Will "nudges" be enough to improve the government's regulatory framework? An archive of Sunstein's writings for the Prospect can also be found here. --The Editors
