Abstract
In 2012, Psy's music video 'Gangnam Style' spread through parodies, and gained explosive popularity. In 2016, there was a case so-called as 'baseball ground cheering song' in which a author(songwriters) claimed an infringement of the 'right of integrity' related to cheering songs used by professional baseball teams. In response, the court denied violating the right of integrity in 2019. These cases have different effects depending on whether or not the 'right of integrity' is claimed. This study attempted an economic analysis in addition to a legal analysis of the right of integrity. Korean copyright law regards even simple changes that go against the author's will as a infringement of the 'right of integrity' even if they do not harm honor or reputation. Such legislation is one of the most strongly protected forms in the world, so it cause many problems. Meanwhile, we analyzed the cost-benefit analysis of Psy's 'Gangnam Style' case and the 'baseball ground cheering song' case. As a result of the analysis, the right to integrity is inefficient in quantitative and qualitative aspects. Therefore, the right of integrity should be reconsidered with the focus on 'popular music'. In particular, considering the development of information communication technology and changes, a revision direction is needed to meet the purpose of the copyright act. Furthermore, in order to solve the legal issues under the Copyright Act, the requirement for infringement of the right of integrity should be relaxed. Then, we proposed the establishment of a proviso clause on the right of integrity.
