Explanation

Since Roberto has the right to play loud music, Thomas can negotiate by paying Roberto an amount between €100 (Roberto's valuation) and €150 (Thomas's valuation) to persuade him to stop playing music. This payment makes Roberto better off by compensating for his loss, and Thomas gains by enjoying quiet, resulting in an efficient solution where Roberto ceases playing loud music.
