Oren Bar-Gill has written Seduction by Contract: Law, Economics and Psychology in Consumer Markets (Oxford University Press 2012). The Introduction is available here. Here's the abstract:
Consumers routinely enter into contracts with providers of goods and services. These contracts are designed by sophisticated sellers to exploit the psychological biases of consumers. They provide short-term benefits, while imposing long-term costs – because consumers are myopic and optimistic. They are excessively complex – because complexity allows sellers to hide the true cost of the product or service from the imperfectly rational consumer. Using both general theory and detailed case studies, this book explains the costs – to consumers and society at large – imposed by seductive contracts, and outlines a promising legal policy solution: Disclosure mandates. Simple, aggregate disclosures can help consumers make better choice. Comprehensive disclosures can facilitate the work of intermediaries, enabling them to better advise consumers. Effective disclosure would expose the seductive nature of consumer contracts and, as a result, reduce sellers’ incentives to write inefficient contracts.
