Retrospective Evaluation of Chemical Regulations
Ex-ante regulatory impact assessment has a long tradition in many OECD countries, with established analytical steps and oversight as well as opportunities for public engagement to hold governments accountable for conducting analysis before regulations are issued. But ex-ante analyses necessarily depend on unverifiable assumptions and models of how the world would look absent the regulation, and how responses to regulatory requirements will alter those conditions. This paper attempts to address the challenges to evaluating regulatory outcomes and learning from those evaluations.
