As absurd as it sounds to express the value of human lives, the environment, or conservation in dollars and cents, cost-benefit analysis requires it. Embraced by a growing number of politicians, economic analysts and conservative pundits as the most reasonable way to make decisions on proposed regulations, cost-benefit analysis attempts to convert all relevant factors into monetary terms. Written by economist CPR Member Scholars Frank Ackerman, economist at the Global Development and Environment Institute at Tufts University, and Lisa Heinzerling, professor of law at the Georgetown University Law Center, Priceless is a combative, no-holds-barred debunking of cost-benefit analysis and the derelict logic used to defend it.
