Ezra Klein focuses on this passage from John Judis’s review of regulatory policy in the Bush and Obama years:
“Bush stopped weighing the costs and benefits of deregulation and issued an executive order allowing OIRA to intercede before agencies made their initial proposals, thereby providing industry lobbyists with a back door to block regulations. OIRA also instructed agencies to discount the value of future lives in constructing cost-benefit analyses by 7 percent a year, so that 100 lives in 50 years would only be worth 3.39 current lives. (Such logic can be used by conservatives to argue that the present cost of regulating greenhouse gases outweighs the future benefits of stopping climate change.)”
There is a normative argument against valuing lives in cost-benefit analysis; some people think it’s just wrong. I don’t agree with that; I think that in practice, you either value lives implicitly or you do it explicitly, and so you might as well do it explicitly. And for what it’s worth, the practice of valuing lives is firmly entrenched in our legal system; the amount you pay in damages if you kill someone negligently depends primarily on that person’s future earning potential, and also on the monetary value of the benefits that other people gained from his or her life.
