‎'‎Regulatory policy debates often fail to serve a constructive role‎.‎ Advocates of risk and environmental regulation maintain that only with zero risk will we be safe‎.‎ Economic critics seek to impose cost‎-benefit tests on these policies that many believe ignore the distinctive character of safety and the environment‎.‎ In Risk and Reason‎,‎ Cass Sunstein eliminates the impasse in the regulatory policy debate with a balanced policy perspective that recognizes the legitimacy of these competing concerns‎.‎ Sunstein‎'‎s carefully crafted analysis shows how the limits on society‎'‎s resources can be reconciled with a vigorous effort to protect citizens and the environment‎.‎‎'‎ W‎.‎ Kip Viscusi‎,‎ Harvard Law School ‎'‎Cass Sunstein is an outstanding scholar and I have been vastly impressed by almost everything I have read of his‎.‎ This work explains and justifies the increasing use of cost‎-benefit analysis in American regulatory contexts‎.‎ It reveals how the technique‎,‎ when suitably adapted‎,‎ can counteract ‎'‎irrationalities‎'‎ in the perception of risks‎.‎ I appreciate Sunstein‎'‎s clarity of expression and fluidity of style‎;‎ and he is able to draw on empirical and other studies while remaining reader‎-friendly in his approach‎.‎‎'‎ Anthony Ogus‎,‎ University of Manchester ‎'‎Professor Sunstein has contributed a masterly and multifaceted analysis of government policy towards the protection of the population from risks‎.‎ The central theme‎,‎ the use of rational methods‎,‎ mainly cost‎-benefit analysis‎,‎ but also more market‎-based forms of regulation‎,‎ is analyzed from an extraordinary variety of viewpoints‎.‎ The author has drawn‎,‎ with deep knowledge and originality‎,‎ on recent developments in cognitive psychology and in legal doctrine to complement rationalistic and economic viewpoints‎.‎‎'‎ Kenneth J‎.‎ Arrow‎,‎ Stanford University ‎'‎In his fine book Risk and Reason‎,‎ Cass R‎.‎ Sunstein offers a wide‎-ranging analysis of the problem of managing environmental health risks‎.‎‎'‎ Science ‎'‎Sunstein offers a sophisticated argument as to how we should reason about risk through cost‎-benefit analysis‎,‎ and how this reasoning can improve risk regulation‎.‎ This book is worth reading‎,‎ both because of its comprehensive scholarship and because it exemplifies a particular approach to law and economics‎.‎‎'‎ Journal of Law and Society
