A research article by CARD economist Dave Keiser and Joseph Shapiro of the University of California, Berkely was picked as an Editor’s Choice article by Science magazine. Keiser and Shapiro’s article “Consequences of the Clean Water Act and the Demand for Water Quality” was originally published by Quarterly Journal of Economics in September.
Keiser and Shapiro assembled the most comprehensive set of files ever compiled on U.S. water pollution and its determinants for their study. They found that the Clean Water Act has been effective in reducing pollution. More information about their study can be found here.
