Study Notes

Market Failures

Market failures occur when the market does not efficiently allocate resources.
This results in either overproduction or underproduction of goods and services.
Overallocation occurs when resources are used to produce more of a good than desired.
Underallocation occurs when resources are used to produce less of a good than desired.

Types of Market Failures

Externalities: Costs or benefits that affect third parties not directly involved in a transaction.
- Negative externalities: Costs imposed on third parties (e.g., pollution).
- Positive externalities: Benefits received by third parties (e.g., education).
Public Goods: Goods that are non-excludable (difficult to prevent people from consuming) and non-rivalrous (one person's consumption doesn't reduce another's).
- Examples include national defense, public parks, and street lighting.
Imperfect Information: When one or both parties to a transaction have imperfect information regarding a product or service.
Market Power: The ability of a single firm or a small group of firms to influence the market price.
- This can lead to underproduction and higher prices.
- Examples include monopolies and oligopolies.

The Coase Theorem

The Coase Theorem suggests that, under certain conditions, private bargaining can solve externality problems without government intervention.
These conditions include well-defined and enforceable property rights, a small number of parties involved, and low transaction costs.

Government Intervention

Government intervention may be necessary when private bargaining is not an effective solution.
It can involve taxes, subsidies, regulations, or market-based solutions like cap-and-trade systems to correct externalities.
Government intervention can involve unintended consequences and high costs.

Efficient Markets

In efficient markets, resources are allocated in a way that maximizes societal welfare.
This occurs when the demand curve reflects consumer willingness to pay and the supply curve reflects all production costs, including externalities.
An efficient market produces the equilibrium quantity of goods and services at the lowest cost.

Surplus

Consumer surplus: The difference between the maximum price a consumer is willing to pay for a good and the actual price they pay.
Producer surplus: The difference between the price a producer receives for a good and the minimum price they are willing to accept.

Productive Efficiency

Productive efficiency occurs when goods and services are produced at the lowest possible cost, using available resources efficiently.
This typically corresponds to producing at the minimum point of the average cost curve.

Allocative Efficiency

Allocative efficiency occurs when resources are allocated to produce the goods and services that society values most.
This corresponds to producing where marginal cost equals marginal benefit.
