Imagine that you are you with your neighbour in the countryside in a big house.

Suppose that your neighbour decides to learn to play the piano. He plays it loudly and this distracts you.

The diagram below illustrates the situation. Your marginal costs tend to increase in the number of hours he plays the piano, while your marginal benefit in this case is zero for all hours. Your neighbour is marginal cost of playing the instrument is zero regardless of the number of hours. His marginal benefit declines if he increases the number of hours he plays.

A) how much money your neighbour should pay for you if he wants to play more hours (from ... To)? What do you want to pay this money?
