초록
본 연구는, 경쟁기업 간 기술이전이 빈번하게 일어나는 ICT 산업에서, 중간재를 독점 공급하는 공급자에 의한 가격차별의 사회후생 효과를 분석한다. 특히 선행 연구들이 생산배분 왜곡(allocational inefficiency)에 근거하여 중간재 가격차별이 사회후생 수준을 저하시킨다고 결론지었던 것에서 출발하여, 본 연구는 양(+)의 기술이전 효과를 새롭게 조명하고 중간재 가격차별이 사회후생 수준을 향상시킬 수 있는 필요충분조건을 제시한다. 이와 더불어 기술투자를 통해 신기술의 습득과 이전이 가능한 경우 중간재 가격차별은 기업들의 기술투자 의욕을 감소시킴을 밝힌다.
Abstract
This research analyzes the effect of input price discrimination in the vertically-related market where a downstream firm shares its cost-saving technology with its competitor through technology licensing. First, it shows that whether input price discrimination by the upstream monopolist is banned or not, the licensor chooses the royalty contract. Second, banning input price discrimination improves social welfare if and only if the licensor’s technical advantage is maintained after technology licensing. Third, banning input price discrimination encourages the downstream firms’ technology investment in the long run. In summary, if the firm having advanced technology is more likely to develop further cost-saving technology, banning input price discrimination improves social welfare both in the short run and in the long run.
