"Provides an authoritative guide to evidence-based social policy by some of the leading scholars in the field. For anyone who wants to know what works, what's worthwhile, and what research would have the greatest payoff, this book has benefits far exceeding the cost."-Philip Cook, ITT/Sanford Professor of Public Policy, Duke University"This book sets out ideas about the kinds of information that could and should be available when major social policy decisions are being made. But, more than that, it provides a broad review of what is available now and of what might be desired in the short and long run. The logic is compelling."-Eric Hanushek, senior fellow, Hoover Institution, Stanford University"This volume contributes to the new burst of interest in the topic of benefit-cost analysis, especially as applied to social policies. The editors have chosen outstanding authors, and their contributions are both enlightening and provocative. The book makes a major contribution toward furthering the application of sound analysis across [a] range of options."-Robert Haveman, professor, Robert M.
