Reasons for government intervention in markets (1 questions)
Answer:
Market Failure with Public Goods: The core market failure with public goods is free-rider problems. Public goods are non-excludable (it's difficult to prevent people from consuming the good even if they don't pay) and non-rivalrous (one person's consumption doesn't diminish the amount available for others). This leads to a situation where private firms are unwilling to supply the good because they cannot capture the benefit from those who don't pay. Consumers, aware they can benefit without contributing, have an incentive to be free-riders. As a result, the market will under-allocate to public goods, leading to a level of provision below the socially optimal level. This is because the marginal social benefit (MSB) of a public good often exceeds the private benefit (PB), but the market price reflects only the PB.
Government Intervention: Governments typically intervene through direct provision (e.g., national defence, street lighting) or subsidies (e.g., for renewable energy). Direct provision ensures the good is available regardless of ability to pay. Subsidies encourage private firms to provide public goods by covering some of the production costs. Regulation can also be used, such as requiring certain levels of environmental protection.
Effectiveness: Government intervention can be effective in addressing the market failure. It can lead to a more efficient allocation of resources and provide benefits that the market would otherwise miss. However, there are potential drawbacks:
- Information Problems: Governments may lack the information needed to efficiently determine the optimal level of public good provision.
- Bureaucracy and Inefficiency: Government provision can be bureaucratic and inefficient, leading to higher costs than private provision.
- Political Capture: Government decisions can be influenced by political considerations rather than economic efficiency.
- Taxation: Funding public goods through taxation can disincentivize work and investment.
The effectiveness of government intervention depends on the specific public good, the design of the intervention, and the overall economic context.
