Study Notes
Market Imperfections and Government Intervention
- Market Imperfections: Imperfect competition (like monopolies), lack of information about product risks, externalities (effects on third parties), and economic instability (unemployment, inflation) justify government intervention.
- Information Asymmetry: Consumers may not have complete information about product safety or occupational risks. Government regulation can help by mandating testing for new drugs and setting safety standards.
-
Externalities: Market transactions can have unintended consequences on individuals not involved in the exchange. These effects can be positive or negative.
- Negative Externalities: Examples include pollution, noise from airplanes, and the decline in property values due to industrial waste.
- Positive Externalities: Examples include fire prevention efforts and smoke alarms, where the presence of these measures benefits the entire community.
- Coase Theorem: This theorem states that a Pareto-efficient allocation of resources can be achieved through bargaining, even in the presence of externalities, provided transaction costs are low. This means that the best solution may emerge through voluntary agreements between parties, without government involvement. However, it is important to note that the allocation of property rights can greatly impact the distribution of income, even though the efficiency outcome remains the same.
-
Free Rider Problem: Individuals can benefit from public goods without contributing to their cost. This arises because public goods are non-excludable (people cannot be prevented from using them) and non-rivalrous (one person's consumption does not reduce the amount available for others).
- Larger groups magnify the problem: As the group size increases, each individual is less likely to contribute, as they perceive their contribution to be less impactful.
- Compulsory Taxation: Governments use compulsory taxation to finance public goods, ensuring contributions and mitigating the free-rider problem.
Public Goods
- Pure Public Goods: Goods that are non-rival in consumption (one person's use doesn't prevent others from using it) and non-excludable (people cannot be prevented from using it). They often require government provision because private companies cannot effectively charge for them.
- Government Services: Not all government-provided goods are pure public goods. Some services can be priced and sold in the market. However, many involve some degree of collective consumption, making compulsory taxation necessary to avoid free riding.
Economic Stabilization
- Market Failures and Unemployment: Market imperfections can lead to excessive unemployment during economic downturns.
- Government Intervention: Governments use monetary and fiscal policies to stimulate demand and stabilize the economy.
- Inflation Control: Excessive inflation can erode purchasing power and harm financial markets. Government efforts to control inflation are often necessary.
Equity and Efficiency
- Trade-offs: Public policy often involves trade-offs between efficiency (achieving the most output with given resources) and equity (fair and just distribution of resources).
- Normative Economics: This field aims to understand and recommend policies to achieve societal goals, considering both efficiency and equity.
- Information Needs: Normative economists need information about the gains, losses, and transaction costs associated with policy changes to make effective recommendations for resource allocation and achieving equity goals.
Political Equilibrium
- Collective Choice: Governments use voting or other decision-making processes to determine the provision of public goods.
- Tax Shares: Voters consider tax prices per unit of the good being provided when evaluating government proposals.
- Political Equilibrium: An outcome reached when the level of production for one or more public goods satisfies the decision-making rule, tax shares, and individual preferences, resulting in an agreement.
Key Points
- Market imperfections exist: They do not always lead to efficient outcomes, justifying government intervention.
- Trade-offs exist: Efficiency and equity are often difficult to achieve simultaneously, making policy decisions complex.
- Information plays a crucial role: Understanding the implications of policy changes is essential for making informed decisions and achieving both efficiency and equity.
