 Now consider pressure. Suppose \(B\) forgot her lunch at home. Her willingness to buy a sandwich from \(A\) is now greater than it would have been had she not forgotten her lunch; she’ll pay more for a sandwich given than she’s forgotten her lunch than she would had she remembered it. In this case, \(B\)’s hunger exerts a pressure on her that causes her to pay \(A\) a higher price for a sandwich. But there’s nothing unfair about having to pay for (or pay more for) lunch because you forgot your lunch. Pressure does not necessarily make a transaction unfair. Yet, like asymmetries of information, pressure can lead to transactions that are, intuitively, unfair. If \(B\) is drowning and \(A\) offers to save her only if she pays him $100,000, many would say \(A\)’s offer takes unfair advantage of the undue pressure that the threat of drowning places on \(B\).
