불법복제에 대한 규제가 콘텐츠 제작자의 수익에 미치는 영향

Effects of Regulation against Unlicensed Contents Sharing on the Contents Producers' Profit

  • 발행 : 2010.02.28

초록

소프트웨어 제작자들이 불법복제로부터 그들의 제품을 보호하기 위해 노력하는 것처럼 콘텐츠 제작자들도 사용자간 불법 콘텐츠 공유를 규제하기 위해 노력하고 있다. 본 연구는 이러한 시도가 과연 저작권자의 권익을 보호하고 그들의 수익을 극대화할 수 있는 근본적인 해결책이 될 수 있을 것인지에 대하여 경제적 측면에서 논의한다. 이를 위해 불법 콘텐츠 공유에 대한 규제가 제작자의 수익에 미치는 효과를 파악하기 위한 분석적 모형을 개발하고 규제와 비 규제하에서 콘텐츠 제작자의 수익극대화를 위한 최적 조건을 제시한다. 분석결과, 정품 콘텐츠와 불법 복제 콘텐츠간의 충분한 차별화가 어려운 경우에는 불법 복제의 규제가 긍정적인 효과를 줄 수 있으나 정품 콘텐츠와 불법 복제 콘텐츠 사이에 충분한 차별화가 가능한 경우에는 오히려 규제가 없는 경우에 저작권자의 수익이 극대화되는 것으로 나타났다.

As software producers have tried to keep their profit against illegal piracy, contents producers also want to protect their contents from unlawful sharing among users. Some researchers uncovered that the regulation on the unlicensed contents is not the best policy to maximize their profit mainly due to network effect but this issue has been still controversial. In this paper, we develop a model to investigate the effect of regulation against unlicensed contents sharing on the profit of contents producers and present the optimal condition to maximize profit of contents producers under the regulation and non-regulation of unlicensed contents. As a result, we analyzed that the firm's payoff under the regulation on unlicensed contents is not always greater than the payoff under the non-regulation because of network externality. If the additional utility from off-line purchase of type P consumers (who enjoy the additional benefit of off-line purchase) is large enough, then the firm's payoff is maximized without regulation.
