We explore learning and change in standard form contracts. We hypothesize that drafters (sellers) are more likely to revise the terms they offer when they have an opportunity to learn about their value. These opportunities arise only for those types of terms that allow drafters to experience the relative costs and benefits of offering them. Consider a warranty. Sellers offering a warranty in an initial period will be exposed to claims about malfunction by purchasers and will learn whether it is desirable to offer it going forward. When drafters are unable to learn, either because they fail to offer such learning-enabling terms initially, or because the term in question is one where there is no increased opportunity to learn, we expect that such terms will be revised less frequently. Indeed, a reduced opportunity to learn might create contractual “black holes,” where terms that are less likely to be revised might lose their meaning over time or appear less related to the rest of the contract. Our results support this hypothesis. Using a large sample of changes in consumer standard form contracts over a period of seven years, we find that sellers are more likely to revise terms that offer an opportunity to learn than those that do not. The results suggest that standard form contract terms evolve over time as sellers learn about their benefits, costs, and risks. Our results have normative implications for the design of default rules.
