Lecture 06: Cost/Benefit Analysis

The lecture provides a comprehensive and rigorous introduction to cost-benefit analysis, a cornerstone of public policy evaluation. Prof. Gruber’s expertise is evident in his clear explanations and use of real-world examples. The content is well-structured, starting with the three valuation methods and then applying them to time and lives. The discussion of contingent valuation’s pitfalls is particularly strong, highlighting the importance of method choice. The revealed preference approach is well-motivated, and the gas crisis example is a classic illustration of a quasi-experiment. The lecture also tackles the ethical dimension of valuing lives, presenting compelling cases that demonstrate the necessity of such valuations in policy. The sources are reliable, primarily the textbook and academic literature, and the lecture is part of MIT OpenCourseWare, ensuring high educational standards. The only minor weakness is the lack of a formal derivation of the value of statistical life, but this is appropriate for an introductory course. Overall, the lecture is excellent in both content and delivery.

The title accurately reflects the content, which is a detailed lecture on cost-benefit analysis methods and applications.
