Satisfaction Guaranteed: When Moral Hazard meets Moral Preferences

NBER Program(s):IO, LE, PE

Theorists and policy analysts have convincingly argued that greater trust makes a more efficient society by eliminating costly contracts or expensive reputations. Concurrently, experiments suggest that reciprocity is a potent substitute for law when compliance with contracts is imperfectly enforced. This paper examines these issues within the context of a common trust-building contract device: satisfaction guaranteed. We find that satisfaction guaranteed indeed builds trust and improves efficiency. Interestingly, sellers offering a guarantee are more trustworthy than those who don't, even when honoring it is fully voluntary, but the guarantee only elicits the trust of buyers when it has legal backing.
