Why policies should be based on careful consideration of their costs and benefits rather than on intuition, popular opinion, interest groups, and anecdotes. Opinions on government policies vary widely. Some people feel passionately about the child obesity epidemic and support government regulation of sugary drinks. Others argue that people should be able to eat and drink whatever they like. Some people are alarmed about climate change and favor aggressive government intervention. Others don't feel the need for any sort of climate regulation. In The Cost-Benefit Revolution, Cass Sunstein argues our major disagreements really involve facts, not values. It follows that government policy should not be based on public opinion, intuitions, or pressure from interest groups, but on numbers--meaning careful consideration of costs and benefits. Will a policy save one life, or one thousand lives? Will it impose costs on consumers, and if so, will the costs be high or negligible? Will it hurt workers and small businesses, and, if so, precisely how much? As the Obama administration's "regulatory czar," Sunstein knows his subject in both theory and practice. Drawing on behavioral economics and his well-known emphasis on "nudging," he celebrates the cost-benefit revolution in policy making, tracing its defining moments in the Reagan, Clinton, and Obama administrations (and pondering its uncertain future in the Trump administration). He acknowledges that public officials often lack information about costs and benefits, and outlines state-of-the-art techniques for acquiring that information. Policies should make people's lives better. Quantitative cost-benefit analysis, Sunstein argues, is the best available method for making this happen--even if, in the future, new measures of human well-being, also explored in this book, may be better still.

"If a paternity test were done on South Africa's widely admired Constitution, whose DNA would come up? Is the Constitution just a beautiful piece of paper? If Oliver Tambo were alive today, walking around South Africa, would he be pleased with what he saw? In this riveting, direct account of the genesis of South Africa's Constitution, former Justice Albie Sachs answers these crucial questions. In Oliver Tambo's Dream, Sachs writes about the years he spent working under Tambo's leadership in exile preparing for a post-apartheid constitutional order in South Africa and about the extreme crises that were overcome during the post-1990 constitution-making process to arrive at the document we have today. Tackling the burning issues that face our country today, he argues that the Constitution is a framework for struggle and decolonization that can be used to bring about land reform and true equality"--
