In Search of Skeptics: "There's a famous movement in the legal world called "law and economics." Originally a conservative cause (famously associated with Judge Richard Posner of the 7th Circuit Court of Appeals) but quickly attracting advocates of all stripes (including the decidedly unconservative Judge Guido Calabresi of the 2nd Circuit), the movement presses law to justify itself in terms of its consequences. What good does a particular regulation do? Does it achieve what it promises? Is there anything more to its authority than its pompous invocation of time immemorial?"
