How can government regulation address information asymmetry?

• A. Lowering taxes on insurance policies.
• B. Mandatory disclosures, licensing, quality standards, and certification programs.
• C. Providing subsidies to all producers regardless of quality.
• D. Allowing firms to operate without any regulation.

Answer: (B)

Regulation that addresses information asymmetry relies on giving buyers reliable signals about product quality and who is supplying it. Mandatory disclosures reveal important details that buyers would otherwise have to guess, such as risks, features, costs, and terms. Licensing screens who can offer a service, ensuring a minimum level of competence and trust. Quality standards set baseline requirements so every product or service meets a safe, acceptable level. Certification programs provide a recognized mark that helps consumers compare options and feel confident in what they’re buying. Together, these mechanisms reduce information gaps, deter misrepresentation, and lower the cost of evaluating options, which makes markets work more efficiently.

Lowering taxes, subsidizing all producers regardless of quality, or allowing firms to operate without regulation don’t fix the information gaps buyers face and can even encourage low-quality providers to fill the market, weakening overall welfare.
