When discussing environmental regulations, “costs are brought to the forefront as reasons why we shouldn’t take a certain policy action, but benefits are often hidden, because they lie in health gains, mortality avoidance, or protection of a habitat or species,” said economist Nicholas Sanders. Sanders “speaks the language of regulation,” by comparing costs and benefits in dollar values. Among the topics he has studied are the long-term consequences of early-life lead exposure; how acid rain controls impacted agriculture; the interaction between influenza cases and air pollution; and improvements in fetal health attributable to the Clean Air Act. “Economics is not about money or finance – economics is about choice,” he said. “It’s easy to see the cost of making a sacrifice or an investment today, but what do we dodge in 50 years if we make that investment now? I try to bring to light the things that people can’t see, but that we all need and value.”
