본 연구에서는 고유가대응 정책수단 사이의 적정 배분을 위한 비용-위험 기준 포트폴리오 모형에 근거하여 예산배분모형을 제시한다. 이와 함께 유가대응 정책수단별로 2000년부터 2006년까지 정부예산에 대하여 적정 배분안을 시산하였다. 시산결과에 따르면 선물시장을 활용한 대안에 일정 금액 이상의 예산이 배분될 필요가 있다. 전략비축 대안의 경우 과다한 비용으로 말미암아 비용-위험 기준 포트폴리오 전략에서는 제대로 고려되지 못하는 것으로 나타났다. 유전개발 대안은 본 연구에서 다른 대안들에 비해 소요비용이 상대적으로 낮게 설정되었기 때문에 비용-위험 포트폴리오 전략에서 절반 이상으로 편입되는 것으로 나타났다.

It is essential to carry out an economic analysis on public water supply projects so that policy makers and water enterprises are aware of the actual value of the project. However, many popular approaches based on discounted cash flow analysis do not capture the uncertainties inherent in cash flow. In order to analyze the economic values of the water supply project of local governments, we utilize real option model, which considers uncertainty in future water price behavior and captures the value of real life flexibility. The real option model is designed to incorporate the option to expand and abandon, and it is applied to a local government case. Furthermore, we assess the project by exploring Luehrman's option space to accommodate the more efficient decision making. The results show that substantial amount of potential value is included in the public water supply service, and the overall value is greater than the value obtained from the discounted cash flow model.

This paper experimentally studies the performance of negotiation considering individual and party, like a country, share of benefit over the best ones. It experiments two-stage bargaining games, internal and external negotiations. From the experimental results, this paper shows strong tendency to select fair allocation in the internal negotiations, but the tendency would be weaker with attractive outside option. In addition, the outside option may claim difference in individual benefit. From the regressions on individual performance in the negotiations, being a proposing party would matter to enhance the performance. However, relative individual performance within party fairness matters. Still attractive no-agreement options happen to break the tendency. As policy implication for trade negotiation, this paper warns that possible loss in individual benefit from not active participation to the external negotiations, no active role of proposer in case that players stick to internal allocations, and deviation of advantageous sector due to attractive outside options.

Recently, China & Japan have expanded their responding ADIZ(Air Defence Identification Zone) to implement each Government's maritime policy and to project their Air Power in preparation for maritime provocation & contingency, especially over the piled area where East Asia countries have claimed to have maritime jurisdiction one another. So this is to guide the Development Option for Korea Air Defence Identification Zone to cope with the maritime intentions of the neighboring countries, considering the international law for ADIZ, the maritime policy and the maritime sovereign & jurisdiction area of the Republic of Korea, etc.

In the soft drink industry, especially small and medium enterprises in Japan, there is a possibility of conversion from a labor-intensive industry to a capital-intensive. The demand for soft drinks may not be satisfied in the summer because the supply is too low to meet the demand. To address this situation, this paper proposes optimal investment that integrates demand uncertainty, based on real options approach (ROA) and seasonal autoregressive integrated moving average. Two alternative options are compared and evaluated. One is the Bermudan option: to employ additional workers to elevate efficiency in summer and laying off in winter, this attitude is repeated each year. The other is the American option: to replace equipment to increase machine ability throughout the year. Results in ROA show that the highest improvement is gained if the two options are in a symbiotic relationship. Soft drink producers should search for replacing equipment, using the employees repeatedly. A temporary decision is not equal to an infinite decision.

This paper's objective is to draw a decision guideline to continue research and development (R&D) investments in biotech start-ups facing the "Valley of Death" syndrome - a long negative profit period during a financial crisis. The data include financial indices as Net income, Revenues, Total stockholders' equity, Cash & equivalents, and R&D expenses of 18 major biotech companies (nine in negative profit and nine positive, in FY2008) and 15 major pharmaceutical corporations as benchmarks both in FY2008 and in FY2016 derived from the US SEC Database, EDGAR. A first methodology dealing with real options analysis assumes Total stockholders' equity as a growth option. And a second methodology, Bayesian Markov chain Monte Carlo (MCMC) analysis, is applied to test the probability relationship between the Total stockholders' equity and the R&D expenses in these three groups. This study confirms that Total stockholders' equity can play the role of a call option to support continuing R&D investments even in negative profits.

This paper analyses the investment options of groundwater development project under water price uncertainty. The optimal investment threshold price which trigger the investment are calibrated base on monopolistic real options model. Stochastic dynamic model is set to reflect the uncertainty of water price which follows the GBM (Geometric Brownian Motion) process. Our finding from non-cooperative investment decision model is that uncertainty of water price could deter the groundwater investment by considering the existence of option values. For policy markers, it is easy to manage 'charges for utilization of groundwater' rather than 'performance guarantee ratio' when managing groundwater investment with pricing policy. And it is necessary to make comprehensive and well-designed policies considering the characteristics of regional groundwater reservoir and groundwater developers.

기후변화 대응과 탄소중립 실현을 위해 산림 바이오매스의 에너지 이용은 중요한 과제이다. 이 연구의 목적은 목재칩 보일러를 주력으로 사용하는 산림에너지자립마을의 투자 타당성을 분석하고 시설의 지속적 운영을 위해 필요한 적정열 보조금 수준을 산출하는 데 있다. 분석을 위해 순현재가치법과 선택의 유연성을 고려한 콜옵션 가격결정모형을 이용하였다. 분석결과에 따르면, 현재와 같이 국비 50%를 지원하고 전력에만 REC를 인정하면 산림에너지자립마을의 순현재가치와 내부수익률은 모두 음(-)이며, 실물옵션 모형으로 평가한 투자가치도 0으로 나타났다. 따라서 에너지 시설의 지속적 가동을 위해 정부 보조금이 필요하다. 시뮬레이션을 통해 사업의 옵션가치를 0보다 크게 만드는 열보조금 수준을 도출하였는데, 최소 0.0248원/kcal으로 나타났다.

Defense offset is considered to be all effective way of acquiring defense critical technologies and arms components as a counter-trade obligation ill defense acquisition contracts. Although arranging the offset contracts is wide]y perceived as necessary, there hardly exists an acceptable model of valuation of the offset technology. By undertaking the technology valuation approach and applying the option approach tn the offset program, we present an offset technology valuation model that maximizes social net benefit of the countries transferring the technology. This article applies our model to an actual case of defense technology transfer in the Republic of Korea. The contribution of this paper is in applying the option approach to the valuation of defense onset technology, providing for the additional flexibility to tile analysis. Our research suggests several policy implications that can be applied to the actual process of defense offsets. Our results elucidate managers' role and responsibilities in designing such a process by applying option approaches.

This paper has an intention of proposing useful parametric tables of each industry group within Korea. These parametric tables can be insightful criteria for those who are dealing with the exact valuation of company, technology or industry through Real Option Analysis (ROA) since the identification of the movement of underlying asset is the very first step to be done. To give the exact estimations of parameters and the most preferred model in each industry group, we cover topics on ROA, stochastic process, and parametric estimation method like Generalized Method of Moments (GMM) and Maximum Likelihood Estimation (MLE). Additionally, specific industry groups, such as, Internet service group and mobile telecommunication service group defined independently in this paper are also examined in terms of its property of movement with the suggesting of the most fitting stochastic model.
