Suppose that a mechanic owns a building and is renting part of the building's space to a library. further suppose that because the mechanic is the owner, he has the right to make noise during the day while he fixes cars. while the library cannot insist on a quiet environment, it could move to a quieter building. however, rent in the next best building is $400/month more than rent in the noisy building. the mechanic can adopt a new technology that eliminates the noise for $325/month. given this situation, can the library find a private solution with the mechanic that will make both better off?
