Worst-Case Scenarios

"Worst-Case Scenarios is an important and timely book. -- Glenn C. Altschuler Baltimore Sun 20071230 Sunstein's book is best when he discusses how we weigh up the costs of protecting ourselves against the benefits of doing so. Many object to cost-benefit analysis, regarding it as cold and mechanical, particularly the placing of monetary value on human lives. Sunstein accepts it is a rough instrument, but he argues that many of us implicitly use it. -- Michael Skapinker Financial Times 20080202 Sunstein writes engagingly, though in a way that scolds us a little for our irrational foibles; and he can illuminate very complex areas of rational choice theory--controversies about future discounting, for example (most of us prefer the certainty of $10,000 now to the certainty of a larger sum ten years hence, even adjusted for inflation), and commensurability (the assessment of such diverse consequences as monetary loss, moral loss and the loss of a zoological species in some common currency of analysis)--so that intelligent thought about decision-making in conditions of uncertainty is brought within reach of the sort of non-specialist reader who is likely to have a practical or political interest in these matters...Sunstein illuminates a whole array of difficult and technical issues: the logic of irreversibility, the basis of low-level probabilistic calculations, the ""social amplification"" of large single-event losses, different ways of taking into account effects on future generations and ways of thinking about the monetisation of disparate costs and benefits. -- Jeremy Waldron London Review of Books 20080410"
