This grant supports a project led by Richard Morgenstern of the nonpartisan think tank Resources for the Future (RFF) to study the effects of specific regulations governing food safety, industrial water pollution, air toxics, and municipal water pollution. Morgenstern will also commission up to six additional regulatory assessments by outside academics whose research techniques meet high scientific criteria. The studies will focus not only on the evaluation of the specific regulations themselves, but on how new datasets and measurement capabilities can improve regulatory design and support more effective regulatory assessment. Results will be disseminated through a formal report and workshop targeted at relevant stakeholders in the government, academic, and NGO communities, and through a series of online outreach activities.
