Lessons from 50 Years of the Clean Air Act, with Maureen Cropper

This week, host Daniel Raimi talks with Maureen Cropper, an economics professor at the University of Maryland and senior fellow at Resources for the Future (RFF). Raimi asks Maureen about a paper she recently coauthored, which takes a retrospective look at the Clean Air Act, as this year we mark the 50th anniversary of its 1970 amendments. With more than 50 years of data since the original Clean Air Act came into existence in 1963, Cropper et al.'s new paper reviews how the law has been implemented, drawing out key lessons and research questions that we may be able to apply to good effect in the next 50 years.
