Socially Efficient and Inefficient Market Outcomes - AP Microeconomics
- Find the equilibrium price in a market.
- Price where quantity supplied equals quantity demanded. Where supply and demand curves intersect.
- What outcome is achieved by internalizing an externality?
- Achieves social efficiency. Makes external costs and benefits part of market decisions.
- Which diagram illustrates socially efficient outcomes?
- Supply and demand curve where MSC = MSB. Shows intersection where social optimum is achieved.
- Identify a cause of market failure.
- Externalities. When markets fail to account for external effects.
- What is the role of government in public goods?
- Provision and financing. Government must supply non-excludable, non-rivalrous goods.
- Which policy tool addresses positive externalities?
- Subsidies. Payments that encourage production with external benefits.
- What does MSB stand for in microeconomics?
- Marginal Social Benefit. Total benefit to society including external benefits.
- What happens when MSC exceeds MSB?
- Overproduction occurs. Market quantity above socially optimal level.
- What is a common solution for a positive externality?
- Government subsidy. Compensates for external benefits causing underproduction.
- Define a positive externality.
- A benefit received by a third party from a transaction. External benefits flowing to parties outside the transaction.
- Identify the impact of a negative externality on supply.
- Shifts supply curve leftward, increasing price. External costs raise true social cost of production.
- Find the socially optimal quantity on a demand curve.
- Where MSB equals MSC. Point where social marginal benefit equals social marginal cost.
- Which term describes failing to allocate resources efficiently?
- Market failure. When markets don't achieve socially optimal outcomes.
- What happens when MSB exceeds MSC?
- Underproduction occurs. Market quantity below socially optimal level.
- What is the outcome when goods are overproduced?
- Socially inefficient due to negative externalities. Market produces more than socially optimal quantity.
- What is the result of a subsidy on a positive externality?
- Increases consumption to the socially optimal level. Compensates for underproduction caused by external benefits.
- What defines a socially efficient market outcome?
- Marginal social cost equals marginal social benefit. This occurs where social costs and benefits are balanced.
- How does a Pigouvian tax affect supply?
- Increases the cost of production, reducing supply. Forces producers to internalize external costs.
- What does a deadweight loss indicate in a market?
- Loss of economic efficiency. Shows society is worse off than at optimal allocation.
- Define a negative externality.
- A cost suffered by a third party due to a transaction. External costs imposed on parties not in the transaction.
- Identify the market outcome if goods are underproduced.
- Socially inefficient due to positive externalities. Market produces less than socially optimal quantity.
- What is the formula for total social surplus?
- Total social surplus = Consumer surplus + Producer surplus. Combines benefits to consumers and producers in the market.
- What does internalizing an externality mean?
- Adjusting market incentives to reflect external costs/benefits. Making external effects part of private cost-benefit calculations.
- What does MSC stand for in microeconomics?
- Marginal Social Cost. Total cost to society including external costs.
- Which condition indicates a market failure?
- Marginal social cost differs from marginal social benefit. When social costs and benefits aren't equated.
- What is an external cost?
- A cost not reflected in the market price. Negative spillover not captured in market price.
- Identify a characteristic of a socially inefficient outcome.
- Resource misallocation occurs. Resources aren't allocated to their highest-valued uses.
- Which policy tool addresses negative externalities?
- Pigouvian tax. Tax that equals the marginal external cost.
- What is the Pigouvian tax designed to correct?
- Negative externalities. Tax equals the external cost to internalize the externality.
- State the Coase Theorem.
- Efficient outcomes can be achieved with private bargaining. Assumes low transaction costs and clear property rights.
- What does deadweight loss represent in a market?
- Loss of total social surplus due to inefficiency. Represents welfare lost when markets operate inefficiently.
- Which term describes a benefit to non-buyers and non-sellers?
- External benefit. Positive spillover effects to third parties.
- What is the effect of a price ceiling on social surplus?
- Leads to deadweight loss due to reduced transactions. Creates shortage and prevents mutually beneficial trades.
- What is the role of property rights in market efficiency?
- Clarified rights can lead to efficient outcomes. Clear ownership enables efficient bargaining solutions.
- Find the deadweight loss area on a graph.
- Triangle between supply and demand curves. Area showing lost welfare from market inefficiency.
- What is an example of a public good?
- National defense. Non-excludable and non-rivalrous good requiring government provision.
- What outcome results from a subsidy on production?
- Increases supply, reducing social inefficiency. Encourages more production when external benefits exist.
