Important figures include the Nobel Prize–winning economists Ronald Coase and Gary Becker, U.S. Court of Appeals for the Seventh Circuit judges Frank Easterbrook and Richard Posner, Andrei Shleifer and other distinguished scholars such as Robert Cooter, Hans-Bernd Schäfer, Henry Manne, William Landes, and A. Mitchell Polinsky. Guido Calabresi, judge for the U.S. Court of Appeals for the Second Circuit, wrote in depth on this subject; his book The Costs of Accidents: A Legal and Economic Analysis (1970) has been cited as influential in its extensive treatment of the proper incentives and compensation required in accident situations.[7] Calabresi took a different approach in Ideals, Beliefs, Attitudes, and the Law (1985), where he argued, "who is the cheapest avoider of a cost, depends on the valuations put on acts, activities and beliefs by the whole of our law and not on some objective or scientific notion" (69).
