Outline the role of government in correcting market failure

• A. The government should not intervene in markets.
• B. Taxation and regulation to curb negative externalities, subsidies for positives, provision of public goods, and establishing property rights to prevent overuse.
• C. Only monetary policy is used to correct market failure.
• D. Market failures are permanent; no policy can fix them.

Answer: (B)

When markets fail to allocate resources efficiently, the government steps in to improve outcomes by using tools that align private incentives with social welfare. This includes taxing activities that impose costs on others and regulating those activities to reduce negative externalities, while also subsidizing or supporting activities with social benefits, and providing goods that markets alone won’t supply.

Taxation and regulation help internalize external costs and benefits. A tax on pollution makes the polluter pay for the damage, encouraging cleaner production. Regulations set rules or standards that limit harmful activities (like emission limits or safety requirements). Subsidies encourage activities with positive spillovers, such as education, healthcare, or research and development, which individuals alone might undervalue.

Public goods are another area where the market under-supplies because they are non-excludable and non-rivalrous. The government provides these, such as national defense, public infrastructure, or basic research, to ensure everyone can benefit.

Property rights help prevent the overuse or depletion of shared resources. By clearly defining ownership or access rules (and sometimes using permits or quotas), the government reduces problems like the tragedy of the commons and ensures more sustainable use of resources like fisheries, forests, and clean air.

This combination of taxation, regulation, subsidies, public provision, and clear property rights explains why government intervention is often needed to correct market failures. The other options suggest no intervention, a single policy tool, or that nothing can be done, which doesn’t fit how governments address these issues.
