Suppose that a candy maker owns a building and is renting part of the building's space to a library. Further suppose that because the candy maker is the owner, he has the right to make noise during the day while he makes candy. While the library cannot insist on a quiet environment, it could move to a quieter building. However, rent in the next best building is $300/month more than rent in the noisy building. The candy maker can adopt a new technology that eliminates the noise for $225/month. Given this situation, can the library find a private solution with the candy maker that will make both better off

The best option is to opt for the new technology which eliminates noise for  $225/month.

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
