Question 9
0 / 1 pts
9. You have probably heard people (mainly from the realms of business and politics) say that we should not do anything about global climate change because it is too expensive and will hurt our economy. After experimenting with this model, do you agree with them, or do you think they are missing something (and if so, what is it they are missing)? Are they thinking about only the abatement costs and ignoring the costs related to climate damages? Which of the following best answers this question?
Correct Answer
These people are focusing on the abatement costs and ignoring the costs related to climate damages. In reality, the total costs to the economy are the sum of these two categories and the model shows that the best outcome for the economy comes from a policy that involves a dramatic reduction in carbon emissions.
You Answered
These people are correct in a purely economic sense — curbing carbon emissions is difficult and expensive and will damage the economy.
These people are wrong because they are ignoring the synergy between the discount rate and the optimal emissions control rate.
Question 10
0 / 1 pts
10. Remember that each ECR history reflects a different economic/political policy. Which policy is the best. In selecting your answer below, you have to think about what “best” means — the least environmental damage; the greatest economic gain per person; the easiest policy to implement; or some combination of these?
Correct Answer
The best policy is one that reduces carbon emissions as quickly as possible — resulting in the least environmental damage and the greatest economic gain per person. But, the best policy also has to be realistic and achievable.
You Answered
The best policy is one that optimizes the greatest economic gain per person even though that might result in greater environmental damage because if we are wealthier, we can afford the increased air conditioning costs.
The best policy is one that minimizes the environmental damage even though that would result in a great reduction in the size of the economy.
The best policy is one that requires us to do the least in terms of reducing carbon emissions because this will preserve jobs.
