Abstract

Option pricing model in finance has been applied to price non-financial options, called real options. The real option valuation method is ideally suited to irreversible decision making under uncertainty, including the need to determine the optimal time to act and even change between alternative courses of action as information is collected. Therefore, the real option valuation method is expected to provide a superior and less subjective approach to determining optimal strategies for water resources supply projects, which have been reported to have huge risks due to uncertainties, and investors and policy makers need to build an optimal strategy - when and if to invest - with uncertainties and managerial flexibilities considered.

금융시장에서 옵션과 같은 파생상품의 가격 결정에 이용되는 옵션가격결정모델의 기본개념이 비금융 사업의 옵션가치 평가에 이용되고 있다. 본 논문에서는 실물옵션이라 불리는 이들 비금융 사업 옵션의 특성을 살펴보고, 실물옵션가치평가기법이 수자원 공급 사업의 경제성 평가에 이용되는 방안을 검토해 보고자 하였다. 수자원 공급 사업이 일반적으로 대규모 투자비용이 소요되고, 사업 기간이 긴 이유로 말미암아 경영상의 유연성이 요구되며, 미래의 수익과 비용 흐름이 불확실하다는 것을 고려할 때, 실물옵션가치평가기법은 운영 옵션의 가치를 평가하고, 이를 수자원 공급 사업의 가치 평가 과정에 포함시키므로써, 기존 현금흐름할인법의 단점을 보안할 수 있는 경제적 가치 평가 기법으로 이용될 수 있을 것으로 보인다.
