Olin Program in Law & Economics Working Paper No. 135, 2001). en_US dc.identifier.uri http://nrs.harvard.edu/urn-3:HUL.InstRepos:12795530 dc.description.abstract What does cost-benefit mean, or do, in actual practice? When agencies are engaging in cost-benefit balancing, what are the interactions among law, science, and economics? This Article attempts to answer that question by exploring, in some detail, the controversy over EPA’s proposed regulation of arsenic in drinking water. The largest finding is that science often can produce only “benefit ranges,” and wide ones at that. With reasonable assumptions based on the existing science data, the proposed arsenic regulation can be projected to save as few as 0 lives and as many as 112. With reasonable assumptions, the monetized benefits of the regulation can range from $0 to$560 million. In these circumstances, there is no obviously right decision for government agencies to make. These points have numerous implications for lawyers and courts, suggesting the ease of bringing legal challenges, on grounds specified here, and the importance of judicial deference in the face of scientific uncertainty. There are also policy implications. Agencies should be given the authority to issue more targeted, cost-effective regulations. They should also be required to accompany the cost-benefit analysis with an effort to identify the winners and losers, so as to see if poor people are mostly hurt or mostly helped. en_US dc.language.iso en_US en_US dc.relation.isversionof http://chicagounbound.uchicago.edu/law_and_economics/487/ en_US dash.license LAA dc.title The Arithmetic of Arsenic en_US dc.type Research Paper or Report en_US dc.description.version Version of Record en_US dash.depositing.author Sunstein, Cass Robert dc.date.available 2014-09-08T19:51:05Z workflow.legacycomments DF en_US dash.contributor.affiliated Sunstein, Cass
