Hi can you tell me the answer for these four questions A,B,C,D. Thank you!!

A. Coal provides benefits to consumers in terms of cheap energy. Assume that these benefits are $500 billion per year. However, coal releases GHGs which are responsible for climate change and will cause damage to future generations that are not even born today. An economist, Dr. Tsigaris, estimated that the damages are in the order of $1000 billion per year. What is the socially efficient level?

Select Answer

1.Coal is eliminated from the market 2.Coal is allowed to be extracted

B. Coal provides benefits to consumers in terms of cheap energy. Assume that these benefits are $500 billion per year. However, coal releases GHGs which are responsible for climate change and will cause damage to future generations that are not even born today. An economist, Dr. Tsigaris, estimated that the damages are in the order of $1 trillion per year. Assume that the current generation has the right to use coal and there is no government intervention, then

Select Answer

1.current generation will continue to use coal 2.the current generation will stop using coal

C. One of the best solutions to the above climate change problem is to give rights to future unborn generations not to be harmed by the current generation. Assume future unborn generations have a representative today that wants to protect them. The representative can

Select Answer

1.stop coal immediately which is the optimal solution 2.coal will continue to be used. 3.requires government intervention.

D. Assume property rights are well-defined, there is no transaction cost, no bargaining cost, and unborn generations have a representative today protecting and defending their rights.A solution between the two generations will evolve and the solution would be the best outcome for both. The solution is also independent of who has property rights. Namely, who has rights is irrelevant. It does not matter if the current generation has the right to use coal or if the future generation has the right not to be harmed.
