Net present value (NPV) and return on investment (ROI) are commonly used to evaluate investment in new technologies. Sometimes, however, measuring the value of investment in new IT becomes very difficult due to its wide scope of application coupled with embedded options in its adoption. Therefore, comprehensive but easily understandable methodologies are needed to solve the complicated problems resulting from the complexity of new technologies. This paper employs a real option analysis to evaluate RFID adoption in the supply chain. Real options analysis should be a better way to evaluate a disruptive technology like RFID. However, the pure (probabilistic) real option rule characterizes the present value of expected cash flows and the expected costs by a single number, which is not realistic in many cases. To solve the problem, this paper considers the real option rule in a more realistic setting, namely, when the present values of expected cash flows and expected costs are estimated by trapezoidal fuzzy numbers.

In this paper, we propose the valuation frame of the IT(Information Technology) ventures using ROV(Real Options Valuation) model. Generally, ROV can comprises the traditional valuation method such as DCF(Discounted Cash Flow), which can measure only the tangible value of a firm from the expected future earnings, in that ROV can additionally measure the intangible value such as the strategic value of a firm in the uncertain environment. We set up the hypothetic IT venture future investment plan and assume that there are a growth option and a switching option consequently along the investment time horizon, which are caused by each characteristics of ventures and IT technologies, especially modularity. In the case that there are several embedded real options in the firm's investment plan in a row, we should apply the compound option pricing model as a real option valuation model in order to consider the value interaction between real options. In an addition, we present the results of optimal investment timing analysis using real options approach and compare them. with those of the original assumed investment timing.

파생금융상품이란 주식이나 채권과 같은 기준자산에 대해서 발행되는 2차 금융상품으로써 기존의 재무이론에서는 수리적 모형에 기반을 둔 가격결정모형을 이용하여 가치를 평가하였다. 그러나 이러한 전통적인 가격결정모형은 복잡한 현실세계를 단순화시키기 위한 제반 가정을 요구하기 때문에 이러한 가정이 현실에 부적합한 경우에는 모형가격이 실제가격으로부터 커다란 괴리를 갖게 된다. 본 연구에서는 전통적인 가격결정방법의 단점을 극복할 수 있는 자료 의존적인 인공신경망기법을 제시하고 대표적인 파생금융상품인 국내 전환사채의 가격결정에 적용해 봄으로써 그 가능성을 제시하였다. 인공신경망기법을 전환사채의 가격결정에 적용한 결과 전통적 가격결정방법에 비해 평균절대오차를 70%정도 줄일 수 있다.

Since 1996 when Kosdaq market was set up, serious doubt has been raised regarding the efficiency of the market. The most important question is whether this market can reflect the real value of the venture company quoted on it. In order to answer this question, this study aimed to evaluate venture companies in Kosdaq market adopting the concept of real option theory. From the results of empirical analysis, we found that in the early 2000, there was serious over-valuation problem. On the contrary, in the recent period of economic recession, under-valuation problem is quite prevalent. We also present our methodology and empirical results confirm the conjecture that option premium outweighs the DCF valor for the newly born and high-technology intensive venture companies. We hope that the empirical results shed some light on the policy prescription to improve the efficiency of Kosdaq market.

The valuation of patents is very important, since technology competitiveness is crucial for firms to maintain global competitiveness. But, the patent valuation is difficult and challenging because of the uncertainty affecting their returns. Hence, we propose a patent valuation method by incorporating game theory into the real option model, which can not only potentially recognizes the effect of uncertainty on patent value, but also consider investment decision in a competitive market, as a game between firms. With the model, we can consider dynamic strategy involving an option of patent leveraging strategies enabling the firm to switch among compete, cooperate, or wait modes under different demand or competitive advantage condition.

본 연구는 KOSPI 200 선물을 이용하여 옵션복제방식에 의한 포트폴리오 보험전략을 구축하고 KOSPI 200 지수와 KOSPI 200 구성주식의 일부로 이루어지는 개별 포트폴리오들을 대상으로 실증분석을 하였다. 본 연구의 결과에 의하면, 포트폴리오 보험전략의 성과는 헤지의 대상이 되는 현물포트폴리오별, 보험수준별, 재조정 기준별로 차이가 있는 것으로 나타났다. KOSPI 200 지수포트폴리오에 대한 헤지는 대체로 약세시장에서 포트폴리오 가치하락을 감소시키면서 시세상승에 편승할 수 있는 것으로 나타났다. KOSPI 200 구성주식의 일부로 이루어진 포트폴리오에 대한 헤지는 수익성이 높고 베타값이 높으면서 시가총액이 큰 제조업이나 전기통신업에 속하는 기업의 주식으로 포트폴리오가 구성되었을 때 대체로 헤지성과가 높았다. 또한 KOSPI 200 지수포트폴리오는 보험수준을 낮게 할수록 헤지성과가 높은 것으로 나타난 반면, KOSPI 200 구성주식의 일부로 이루어진 포트폴리오의 경우에는 보험수준과 헤지성과간의 관계가 일정치가 않았다. 재조정 기준별로는 3% 재조정 기준을 적용하였을 때 헤지성과가 가장 높았으며, 가장 빈번하게 재조정을 해야하는 일별 재조정 기준에 의할 경우는 거래비용이 상대적으로 높았다.

The transition from fossil to renewable energy is inevitable due to fossil depletion. So, Renewable energy is very important for energy security and economic growth although it's R&D is long-term and high risky project. We propose new valuation method which combined system dynamics and compound real option method for long-term and high risk projects such as renewable energy. This method can show dynamic valuation results for the complex causal interaction and be easy for Monte-Carlo simulation to estimate volatility. And it can reflect the value of flexible decision for uncertainty. We applied the empirical analysis for Korea's photovoltaic industry by using this method. As results by empirical analysis, photovoltaic's R&D has high valuation using this method compared by traditional valuation methods such as DCF.

Hydrogen energy is emerging as an important means of carbon neutrality in the various sectors including power, transportation, storage, and industrial processes. Fuel cell power plants are the fastest spreading in the hydrogen ecosystem and are one of the key power sources among means of implementing carbon neutrality in 2050. However, high volatility in system marginal price (SMP) and renewable energy certificate (REC) prices, which affect the profits of fuel cell power plants, delay the investment timing and deployment. This study applied the real option methodology to analyze how the dual uncertainties in both SMP and REC prices affect the investment trigger price level in the irreversible investment decision of fuel cell power plants. The analysis is summarized into the following three. First, under the current Renewable Portfolio Standard (RPS), dual price uncertainties passed on to plant owners has significantly increased the investment trigger price relative to one under the deterministic price case. Second, reducing the volatility of REC price by half of the current level caused a significant drop in investment trigger prices and its investment trigger price is similar to one caused by offering one additional REC multiplier. Third, investment trigger price based on gray hydrogen and green hydrogen were analyzed along with the existing byproduct hydrogen-based fuel cells, and in the case of gray hydrogen, economic feasibility were narrowed significantly with green hydrogen when carbon costs were applied. The results of this study suggest that the current RPS system works as an obstacle to the deployment of fuel cell power plants, and policy that provides more stable revenue to plants is needed to build a more cost-effective and stable hydrogen ecosystem.

In recent years, advanced countries in energy sector are emphasizing the importance of the development and deployment of renewable energy to cope with the global environmental crisis such as depletion of fossil energy, climate convention to control emissions of greenhouse gases. In this paper, we evaluate the economic value of the investment in new and renewable energy R&D in Korea and optimal deployment timing of new and renewable energy by using the real option approach. The real option model adopted in this paper assumes that a decision maker has a compound option to abandon, deployment, or continue the R&D. As a result by using empirical data of Korea, it is found that there exists a considerable amount of positive real option value (ROV) in the investment of new and renewable energy R&D while its net present value (NPV) calculated by traditional discounted cash flow (DCF) model shows negative value.

This study presents a new real estate value analysis model considering the changes in the population structure. We propose a new model that takes advantage of the binomial option model one of the techniques of real options and considers the changes in the population structure. The real estate market price data of Seoul city from year 2001 to 2012 were extracted and the correlation analysis between real estate prices and changes in the population structure was performed. The result shows that they have positive correlation with one year time lag. The coefficient between the real estate prices and demographic changes was estimated using the OLS analysis and included in the traditional binomial option model to calculate the value of the property. It is assumed for the future price prediction that real estate invested in Seoul in January, 2013 will be sold within five years. Analysis result shows that the values of real estate in September of 2013 were predicted as 583.5 million won in the new model and as 582.4 million won in the traditional model. This reflects that the new model considering the change of population change gives better realistic performance than the traditional one.
