Chapter 5 Flashcards
How can we divide the 2 types of benefits of pollution control?
1.Market benefits
- Non market benefits
how do we measure non market benefits?
By inferring how much people would be willing to pay (or accept) for these benefits if a market for them did exist.
need to estimate the risk associated.
What is use value?
The value in something’s usage.
What is an option value?
Willing to pay for something to preserve the option that the resource might be valuable in the future.
What is the total value of an environmental resource?
The sum of its existence value, its option value and its use value.
What is the consumer surplus?
the difference between what one is willing to pay and what one actually has to pay for a service or product.
How do we calculate the consumer surplus from a graph?
For a unit: the area of the slot on the graph
For the total CS: adding the different areas
What is the relationship between the consumer surplus and the WTP?
the price that people are willing to pay is a close approximation to the increase in consumer surplus that they enjoy.
So, one can measure the benefits of environmental improvement simply by determining people’s WTP for such improvement and adding the results.
What are the ways to measure consumer surplus?
- WTP
- WTA
What is WTA?
The compensation in exchange for a degradation in environmental quality.
Why is WTA higher than the consumer surplus? Why is WTP lower?
WTA is higher because Individuals are actually made a bit richer when they are compensate for damage.
WTP is lower because as people will be made poorer if they have to pay for environmental improvement.
What explains the divergence between WTP and WTA benefit measure?
- People are more wiling to sacrifice to maintain the existing quality of the environment that they are to improve environmental quality beyond what is already experienced.
- endowment effect - Degree of substitutability between environmental quality and other consumption goods.
- there are no good substitutes
What is the endowment effect?
people may adopt the status quo as their reference point and demand higher compensation to allow environmental degradation than they are willing to pay for making improvements.
this would reshape the marginal benefit curve for pollution reduction - it would dramatically rise within the current levels of pollution.
How do we know whether to use WTP or WTA?
It depends on the property rights.
- WTA - common property resources that belong to “the people”
- giving someone compensation = will generate underestimates of the underlying resource value. - WTP - when an individuals gain benefits from environmental protection.
What is a concern for WTP and WTA?
Rich people because of their high income will be willing to pay more for environmental improvement and will require more to accept for environmental degradation.
