The Doctrine of Double Effect, Deadly Drugs, and Business Ethics
本文讨论双重效应原则在商业伦理中的应用，认为该原则允许企业销售致命产品，只要警告消费者风险，并主张自由市场是权衡商业决策利弊的最佳方式。
Manuel Velasquez and F. Neil Brady apply the doctrine of double effect to business ethics and conclude that the doctrine allows a pharmaceutical company to sell a drug with potentially fatal side effects only if it also has the good effect of saving lives. This forbids the sale of many common products, such as automobiles and alcohol. My account preserves the virtues of the doctrine of double effect without making it too restrictive. I apply the doctrine to a pharmaceutical company’s decision to market a drug with dangerous side effects and argue that free markets often offer the best way to compare the good and bad effects of business decisions. I conclude that the doctrine does allow a business to sell a potentially fatal product that does not save lives, provided that it warns consumers about the danger.
