How can information disclosure policies reduce market failure due to asymmetric information?

• A. Requiring clear labeling and transparent information reduces adverse selection and moral hazard.
• B. Withholding information improves competition.
• C. Disclosure has no impact on adverse selection.
• D. Prices alone fix information problems.

Answer: (A)

Information disclosure policies reduce market failure from asymmetric information by making relevant facts about products, services, and risks visible to everyone. When buyers can’t tell quality, markets can be flooded with low-quality goods (the lemons problem). Clear labeling and transparent information let buyers distinguish higher-quality options, leading to better pricing, more informed choices, and trades that reflect true differences in quality. They also help with moral hazard, because when terms, risks, and expected behaviors are disclosed and monitored, parties face clearer incentives and less opportunity to shirk or take excessive risks after a contract is signed. That combination—improved ability to assess quality and aligned incentives—reduces both adverse selection and moral hazard. Withholding information worsens information problems, while relying on prices alone cannot fully fix hidden attributes or incentives.
