 For many products bought and sold in markets, sellers offer an item at a certain price, and buyers take or leave that price. But in some cases there is negotiation over price (and other aspects of the transaction). We see this in the sale of “big ticket” items such as cars and houses, and in salaries for jobs. While there are many ethical issues that arise in negotiation, one issue that has received special attention is “bluffing”, or deliberately misstating one’s bargaining position. The locus classicus for this discussion is Carr (1968). According to him, bluffing in negotiations is permissible because business has its own distinctive set of moral rules and bluffing is permissible according to those rules. Carson (2010) agrees that bluffing is permissible in business, though in a more limited range of cases. Carson’s argument appeals to self-defense. If you have good reason to believe that your adversary in a negotiation is misstating her bargaining position, then you are permitted to misstate yours. A requirement to tell the truth in these circumstances would put you at a significant disadvantage relative to your adversary, which you are not required to suffer. An implication of Carson’s view is that you are not permitted to misstate your bargaining position if you do not have good reason to believe that your adversary is misstating hers.
