In the excellent historical sections describing the (non-partisan) spread of CBA in US government, Sunstein gives some persuasive examples of how to use CBA well... It's worth the read for anyone interested in the role of reason in policy making.

Clear, well-argued....As Sunstein notes, cost-benefit models have become progressively less wrong and more useful over time, and will surely continue to improve. The cost-benefit revolution may be incomplete and its pace of progress uncertain, but it's far from over. ¡Viva la revolucion!

The book makes three valuable contributions: it relates the history of cost-benefit analysis in US policymaking; it tackles the economist Friedrich Hayek's argument that technocrats simply don't know enough to weigh costs and benefits; and it makes a case that cost-benefit analysis could reduce political tribalism.

[Sunstein's] insights and conclusions are broadly applicable to wherever benefit-cost analysis is practiced...Sunstein thinks deeply, writes engagingly, and is often provocative...[The Cost-Benefit Revolution] is likely to lead to much interesting debate as well as to new developments in the field.
