초록
신제품 개발은 기업의 지속적 경쟁우위 및 기업 생존을 위한 핵심요소로 강조되어 왔다. 또한,기존 연구들은 기업 경영의 투명성이 기업 자원의 효율적 활용을 위한 바탕이 됨을 제시하고 있으나, 기업투명성이 신약개발의 효과에 미치는 영향에 대한 실증적 연구는 없는 실정이다. 이에, 본 연구는 제약업체의 기업투명성이 신약허가 발표시 해당 종목의 조사기간 수익률에 어떠한 영향을 미치는가에 대해서 규명한다. 투자자들이 기업 내부정도에 노출된 정도를 통제했을 때, 신약의 혁신유형은 각기 상이한 경제적 부가가치를 창출하는 것으로 보인다. 또한, 주가수익률 동기성으로 추정된 기업투명성이 높은 제약업체일 수록 산약 허가발표시의 누적초과수익률 또한 개선된다.
Abstract
New product innovations are a key source of sustainable competitive advantage and firm survival. Although corporate transparency has been emphasized for efficient use of firm resources, we know little about the link between corporate transparency and firm value effect of new product innovations. In response, we assess whether corporate transparency of NYSE-listed pharmaceutical companies affects event-study returns upon announcements of FDA approvals. Controlled for investors’ relative exposure to inside information potentially pertaining to approval procedure, innovation types are priced in the announcement returns. Lastly, announcement returns are lower with a pharmaceutical firm lower in corporate transparency, proxied for by stock return synchronicity.
