Market Failure Notes

What is market failure?

Market failure occurs when the market fails to provide a Pareto-optimal level of any good.

What does Pareto-optimality mean?

Pareto-optimality is achieved when no one can be made better off without making someone else worse off.

What are price-takers?

In perfect competition, all buyers and sellers are price-takers, meaning they cannot influence the market price.

What is a price-setter?

A price-setter is someone who can influence the price of a good, usually leading to a higher price than in perfect competition.

What is an incentive compatible institution?

An incentive compatible institution is one that aligns individual self-interest with the general interest, such as a perfectly competitive market.

What causes market failure?

Market failure can be caused by monopolies, public goods, intellectual property, and negative externalities.

What is consumer surplus?

Consumer surplus is the difference between what consumers are willing to pay for a good and what they actually pay.

How does monopoly affect consumer surplus?

Monopoly destroys consumer surplus and creates deadweight loss by setting prices above competitive levels.

What is deadweight loss?

Deadweight loss is the loss of economic efficiency when the equilibrium outcome is not achievable or not achieved.

What is monopsony?

Monopsony is a market situation where there is only one buyer or a coalition of buyers.

What is the relationship between perfect competition and profit?

In perfect competition, real profit is impossible; firms earn zero economic profit in the long run.

What is rent seeking?

Rent seeking is the pursuit of economic gain through manipulation or exploitation of the political environment, rather than through trade and production.

What is the role of game theory in market structures?

Game theory analyzes strategic interactions between buyers and sellers, especially in monopolistic and monopsonistic markets.

What are public goods?

Public goods are characterized by non-excludability and non-rivalrous consumption, meaning they are available to all without diminishing their availability.

What is the Prisoner's Dilemma in relation to public goods?

The Prisoner's Dilemma illustrates how rational agents may refuse to contribute to public goods, opting to free ride on others' contributions.

What is the laissez-faire approach to monopoly?

The laissez-faire approach suggests doing nothing about monopolies, as excess profits will attract new entrants that undermine monopolistic power.

What is the significance of 'rents' in economics?

'Rents' refer to profits earned above the normal competitive level, often resulting from monopolistic practices.

What happens when there is market failure?

When market failure occurs, there is often a presence of price-setters who can manipulate prices away from Pareto-optimal levels.

What are the two conditions that indicate Pareto-optimality fails?

1. Less of a good is provided than consumers are willing to pay for. 2. A higher cost for the good is imposed than would be required under perfect competition.

What is a public good?

A good that is non-excludable and non-rivalrous, meaning that individuals cannot be effectively excluded from use and one person's use does not reduce availability for others.

What is the primary issue with public goods in a competitive market?

Public goods are often undersupplied because individuals have an incentive to free ride, leading to market failure.

What does the term 'free riding' mean?

Free riding occurs when individuals benefit from resources, goods, or services without paying for them, leading to under-provision of public goods.

What is a negative externality?

A negative externality occurs when a producer's actions impose costs on third parties who are not involved in the transaction.

Give an example of a negative externality.

Pollution from a factory that affects the health and environment of nearby residents.

What is the 'Prisoner's Dilemma' in the context of public goods?

A situation where individuals acting in their own self-interest do not cooperate, leading to a worse outcome for all, such as not contributing to public goods.

What is the Schelling diagram used to illustrate?

It illustrates the relationship between the percentage of others cooperating and the payoff to action, showing how cooperation can lead to better outcomes.

What happens when all individuals defect in a public goods scenario?

When all defect, everyone is worse off than if they had cooperated, as the benefits of cooperation are lost.

What is the role of government in addressing market failures?

The government can design incentive-compatible institutions to encourage cooperation and mitigate the effects of market failures.

What is the 'second best' solution in economic terms?

A solution that is not Pareto optimal but aims to come close to efficiency in the presence of market failures.

How do intellectual property rights relate to public goods?

Good ideas are similar to public goods; they are non-rivalrous and difficult to exclude, leading to under-supply in competitive markets.

What is a patent?

A government-granted monopoly that allows an inventor to exclusively produce and sell an invention for a certain period, incentivizing innovation.

What are the conditions for granting a patent?

1. The idea must be practically useful, 2. It cannot be obvious to experts, 3. Full disclosure of the idea is required.

What is the problem with monopolies in the context of patents?

Monopolies can stifle innovation and create inefficiencies, as they can charge higher prices and limit access to new ideas.

What is the impact of a steel mill imposing pollution costs?

The steel mill can sell steel at a lower price because it does not account for the external costs of pollution, leading to inefficiencies in the market.

What is the 'real' supply curve when accounting for negative externalities?

The 'real' supply curve includes the external costs of production, leading to higher prices and lower quantities than the original supply curve.

What strategies can be used to address externalities?

1. Government regulation, 2. Collective action by affected parties, 3. Negotiated agreements between producers and affected individuals.

What challenges arise in calculating the cost of suffering from externalities?

It is difficult to quantify the economic impact of suffering without a market to establish prices.

What is the incentive compatibility of a perfectly competitive market?

In a perfectly competitive market, all agents are price takers, leading to total efficiency without strategic interactions.

What is a strategic action problem in the context of market failures?

A situation where buyers and sellers must consider the actions of others when making decisions, complicating market dynamics.

What is the significance of the concept of 'Pareto efficiency'?

A situation is Pareto efficient when no individual can be made better off without making someone else worse off.

How does the presence of externalities affect Pareto efficiency?

Externalities can lead to situations where resources are not allocated efficiently, resulting in a loss of overall welfare.

What is the relationship between competition and the provision of public goods?

In a competitive market, public goods are often undersupplied due to the free-rider problem and lack of incentives for individual contributions.

What is the role of full disclosure in the patent system?

Full disclosure allows others to understand the benefits of using the patented idea, facilitating informed decisions in the market.

What is the impact of strategic interactions in markets with externalities?

Strategic interactions complicate decision-making, as individuals must consider the potential responses of others to their actions.
