Which statement about information disclosure policies is correct?

• A. Disclosures can reduce adverse selection.
• B. Disclosures always solve all market failures completely.
• C. Disclosures have no effect on market outcomes.
• D. Requiring standardized, transparent information reduces both adverse selection and moral hazard.

Answer: (D)

Information disclosure policies tackle asymmetries in what buyers and sellers know. Adverse selection happens before a transaction when one side has more or better information than the other, so low- or high-quality participants crowd the market. When disclosures are standardized and transparent, everyone can compare risks, quality, and guarantees more easily, which narrows the information gap and makes it harder for low-quality participants to dominate. Moral hazard occurs after a contract: once insured or protected, a party may take more risks or shirk effort because the costs aren’t fully borne. Clear, standardized disclosures create verifiable benchmarks and monitoring signals, making hidden actions easier to observe or deter and reducing the incentive to take on extra risk. So, requiring standardized, transparent information helps address both adverse selection and moral hazard. It’s not a perfect cure for all market failures—there are costs to providing disclosures and limits to what information can reveal—but it targets the main information problems that cause misallocation.
