How to Design Rules for Ex-Post Evaluation


Abstract: Ex-ante cost-benefit analyses and other impact assessments are now a standard part of the rulemaking process. Yet some important effects of regulation are difficult—or impossible—to assess before a rule takes effect. In such cases, ex-post (or retrospective) evaluation, conducted after a rule is in effect, offers an opportunity to measure real-world outcomes that could not reliably be predicted in advance.
