Regulations are often made during times of uncertainty and/or with haste in responding to an emergency of some kind. Ex post evaluation allows policymakers to assess whether regulations have led to the intended results that were espoused when they were first made. This recognises that all regulations are, to some extent, experiments and that some experiments fail, and others need adjusting, before the desired results materialise. As a core component of any regulatory management system, ex post evaluation is ultimately about ensuring that regulations maximise community well-being over time.
This report provides guidance on the key elements of a sound ex post evaluation system. It illustrates practical elements of ex post evaluation that policymakers should follow when designing ex post evaluation systems, as well as how evaluations themselves can be conducted. As such, this report is a useful tool for countries embarking on ex post evaluations as well as for entities responsible for conducting evaluations in practice.
