The term, “Cost-benefit analysis,” is used so frequently that we rarely stop to think about it. But relying on it can lead to some dubious conclusions, as Frank Ackerman points out in this eye-opening book. Inventing dollar values for human life and health, endangered species, and fragile ecosystems does not guide us to better policies, he maintains. Cost-benefit analysis, as practiced today, could have led to damming the Grand Canyon for hydroelectric power, leaving lead in gasoline, and other absurd and harmful decisions. In Poisoned for Pennies, Ackerman uses clear, understandable language to describe an alternative, precautionary approach to making decisions under uncertainty.
