Health-health analysis (HHA) posits a seemingly unassailable criterion for regulatory assessment: policies intended to protect human health ought to exhibit positive health benefits. Despite the apparent logic of this criterion, it is important to ask whether it would aid in the quest for better public policies. In the context of environmental issues, we find that HHA can be useful by reminding us that it is the net health impact of a proposed regulation that can be important. However, we also find that in most applications the health impacts of regulatory compliance costs are unlikely to be significant. Conventional benefit-cost analysis ought to remain the principal tool of economic assessment of environmental laws and regulations.
