'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
