Law & Economics Working Papers
Judge Frank Easterbrook's opinion in ProCD v. Zeidenberg has been heavily criticized for ignoring the law and making unrealistic assumptions about the ability of consumers to read and understand contract terms. This contribution to a symposium on Judge Easterbrook's judicial output argues that the opinion is a classic example of the manipulation of legal doctrine to advance a policy goal— here, enabling sellers to communicate contract terms when buyers' time and attention are limited. Contrary to the conventional wisdom, Judge Easterbrook implicitly assumes that buyers are fallible, not hyperrational; his doctrinal solution persuasively addresses the problem of cognitive overload while endorsing a valuable business tool—the "terms later" or "rolling" contract—that reduces the cost of transacting.
