What is meant by non-rivalry?

A

One person benefitting from a good doesn’t stop others from also benefitting. Its benefit is non-diminishable. This means that public goods have zero marginal cost, there’s no additional cost to extending the good to one more person

Q

What is an example of a non-pure or quasi public good?

A

Roads appear to have the characteristics of a public good as they are often free for everyone to use and one person using a road doesn’t prevent another person from using it too. However tolls can make a road excludable by excluding those who don’t pay to use the road and congestion will make a road exhibit rivalry as there is a limit on the number of people who can benefit from the road at any one time

Q

What is the relationship between the price mechanism and free riders?

A

The price mechanism cannot work if there are free riders

17
Q

Why can’t the price mechanism work if there are free riders?

A

Consumers won’t choose to pay for a public good that they can get for free because other consumers have paid for it

18
Q

What are some of the problems caused by free riders?

A
  • Consumers won’t choose to pay for a public good that they can get for free because other consumers have paid for it
  • If everyone decides to wait and see who will provide and pay for a public good it won’t be provided
  • It’s also difficult to set a price for public goods because it’s difficult to work out their value to consumers
19
Q

What is the difference between consumers and producers valuing the benefits of public goods?

A

Producers will tend to overvalue the benefits of a public good in order to increase the price that they charge. Consumers will undervalue their benefits to try to get a lower price

20
Q

How do the problems caused by free riders lead to market failure?

A

These problems caused by free riders mean that firms are reluctant to supply public goods which causes market failure. As a result governments will usually have to intervene to provide the public good

21
Q

What is the relationship between positive externalities and the free rider problem?

A

Positive externalities are a form of public good. They are consumed by those who don’t pay for them so they are an example of the free rider problem

22
Q

Define resource depletion

A

Resource depletion is the reduction of available natural resources due to their overuse

23
Q

Define resource degradation

A

Resource degradation occurs when natural resources are made less productive by human activity

24
Q

What is the tragedy of the commons

A

The tragedy of the commons is the idea that people acting in their own personal best interests will overuse a common resource without considering that this will lead to the depletion or degradation of that resource

25
What is perfect information
Perfect information means that buyers and sellers are assumed to have full knowledge regarding prices, costs, benefits and availability of products
26
What is symmetric information
Symmetric information is perfect information which is equally available to all participants in a market
27
What will symmetric information allow in terms of the allocation of resources?
Assuming that buyers and sellers are rational in their behaviour this symmetric information will allow the efficient allocation of resources in an between markets
28
What is asymmetric information?
Asymmetric information is when buyers or sellers have more information than each other. Asymmetric information involves a lack of perfect information in a market.
29
Why may a provider of a service have a lack of information?
Providers of some services have a lack of information because the thing they provide a service for is unpredictable
30
What is moral hazard?
Moral hazard is another possible result of asymmetric information. This happens when people take risks because they won't suffer the consequences themselves if things go wrong
31
What is an information gap?
An information gap is where consumers, producers or the government have insufficient knowledge to make rational economic decisions
32
How do information gaps lead to market failure?
Information gaps can lead to market failure due to either consumers or producers having more market knowledge than the other about a particular good or service. This means that there is an unequal balance upon which to conduct economic transactions between them
33
What are the causes of imperfect information/information gaps?
- Misunderstanding the true costs or benefits of a product - Uncertainty about costs and benefits - Complex information when buying specialist products that some consumers will find difficult to understand - Inaccurate or misleading information - Addiction - Lack of awareness
