owns a dog whose barking annoys 's neighbor Jane. receives personal benefit from owning the dog, and Jane bears a cost of 's ownership of the dog. Assuming has the legal right to keep the dog, which of the following choices are true?

a. A private solution can always be arranged.
b. A private solution can be arranged only if the cost Jane bears exceeds the benefit gets from his dog.
c. A private solution can be arranged
only if Jane's cost equals 's benefit from the dog.
d. A private solution can be arranged only if 's benefit from his dog exceeds Jane's cost.

According to Coase theorem, an
economy can always reach an efficient
solution as long as transaction costs are low. So is the answer a)?

You have stated why the answer may not be a. Is a) true if transactions costs are high? (Unless you think that no change because transaction costs are high is, in it self, a private solution).

Unlike many other economics problems with a continuum of possible solutions. Here, either keeps the dog or he doesnt. (He cannot keep 1/2 a dog)

So, look again. What must be true for a transaction to occur where both parties are better off.

I believe is d?

No.

Ask these questions: How much does need to give up his dog? How much is Jane willing to pay to get rid of 's dog.

(Note that one could argue that, under d, an optimal private solution already exists; the value of the dog exceeds the costs from the dog. But, I don't think that's what the question is asking.)

ok, so for d) it means that if has the rights, and its benefit exceeds Jane's cost, wouldn't have to pay Jane anything at all.

Since as the rights, by your initial assumption, then Jane has to pay to get rid of the dog. Think opportunity cost here: Let X be the "cost" to Jane from the barking dog. That is, she would pay up to X to get rid of the dog. Let Y be the "benefit" from the dog to . He would need to be paid an amount of Y or more to get rid of the dog. So, a transaction will only take place if X>Y. Go with b)

a

Yes, you are correct. The correct answer is b) A private solution can be arranged only if the cost Jane bears exceeds the benefit gets from his dog.

Yes, you are correct. The correct answer is b) A private solution can be arranged only if the cost Jane bears exceeds the benefit gets from his dog. In this scenario, for a private solution to be reached, Jane would need to be willing to pay an amount greater than or equal to the benefit that receives from owning the dog.
