한국지질자원연구원에서 1998년부터 2002년까지 기본사업으로 5년간 수행한 대도시 지역 지하수 오염저감기술연구사업의 경제적 파급효과로서 조건부가치측정법을 활용하여 연구사업성과의 비용, 편익, 순현재가치, 비용편익비, 내부수익률을 산정하였다. 분석과제의 주요성과 중 계량화가 가능한 직접 편익은 지하수 음용화 시설 구축에 따른 편익 및 지하수 데이터 가치 편익 두가지로 분석되었다. 이들 편익에 대한 경제적 파급효과를 2002년도 현재가치로 환산한 결과, 비용은 50.9억원, 편익은 676.9억원, 순현재가치는 626.0억원, 비용편익비는 13.3, 내부수익율은 152%로 나타났다.

본 연구의 목적은 농식품부 농어촌종합개발사업의 일환으로 이뤄지고 있는 제주도 한립읍 판포권역의 해거름영농조합법인의 소득기반사업인 콩류 가공(콩나물+두부)의 경제적 타당성분석을 하는 것이다. 구체적인 경제성 분석방법은 순현가와 투자수익률(내부수익률)을 이용한 기본적인 경제성분석과 주요변수들의 변화에 따른 순현가의 변화를 파악하기위한 민감도분석이다. 분석결과에 따르면, 콩나물, 두부 등 콩류 가공사업의 경제적 타당성은 순현가기준 38억 9천7백만원, 내부수익율(IRR) 기준 47.2%로 경제적 타당성이 매우 높은 것으로 나타났다. 사업규모의 변화에 대해서도, 콩나물콩의 사업규모 1,100가마를 고정시킨 상태에서 두부콩 수준의 처리규모를 3,600가마에서 1,400가마까지 처리규모를 축소해 나가도 경제적 타당성이 있고, 또한 기본시나리오에서 콩나물과 두부의 평균가격이 현재가격 대비 75% 수준이 될 때까지는 모든 할인율 수준에서 경제적 타당성이 있는 것으로 나타났다.

This paper examines the pecuniary effects stemming from insider trading in the equities of firms targeted for acquisition. Illegal exchanges by those having advantageous information are found to result in excessive returns to stockholders of the sought firms. However, unusual market activities are not typical immediately subsequent to the illegal trading date, suggesting that nonpublic information is synthesized by market mechanisms with sufficient speed so that others cannot profit by imitating the better informed traders. The obtained evidence does not support the contention that insider trading on nonpublic information harms the outsider stockholders of involved firms.

This study performed a benefit cost analysis of an automatic eggshell crack detection system. Based on various cost benefit analysis methods, including the net present value (NPV), internal rate of return (IRR), and benefit cost ratio (B/C Ratio), the automatic eggshell crack detection system was confirmed to have economic validity. The NPVs were 175,035,645 won at a 5% discount rate and 129,082,393 won at a 10% discount rate. Plus, the IRRs were 0.686 at a 5% discount rate and 0.660 at a 10% discount rate. Finally, the B/C ratios were 1.981 at a 5% discount rate and 1.900 at a 10% discount rate.

This study evaluated the economic value of the development of a new variety of Citrus unshiu using the income approach, Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit/Cost (B/C) ratio. The new variety of Citrus unshiu was developed by the national institute of horticultural and herbal science in Korea, rural development administration. The technological evaluation of the development of a new variety of Citrus unshiu can be used to improve the efficiency and practicality of the development of a new variety of citrus. From the research results, the technological value of development of a new variety of Citrus unshui was evaluated at 109,455(discount rate=8%, minimum), 195,040(discount rate=4%, maximum), and 145,375(discount rate=6%, average) million won. The IRR was 51.4%, which was greater than the discount rate(4~8%). The NPV was evaluated at 145.3 billion won(discount rate=6%, average), 195.0 billion won(discount rate=4%, maximum) and 109.4 billion won(discount rate=8%, minimum), all of which were greater than 0. The B/C ratio was evaluated at 60.9(discount rate=6%, average), 81.3(discount rate=4%, maximum) and 46.1(discount rate=8%, minimum), all of which were greater than 1. Therefore, the economic validity of the development of a new variety of Citrus unshiu was identified by this technological evaluation.

The objective of this study was to develop a GIS application model for analyzing site-specific suitability and investment efficiency of major plantation tree species. The model was designed to choose the best plantation species in terms of both potential stand growth and investment efficiency. Site index and IRR were used as the criteria for the potential of stand growth and investment efficiency, respectively. In the model, the conditions of forest stand management and site index are estimated as the function of site-environmental factors extracted by a series of spatial analyses of digital maps of FGIS. Based on site index values of tree species, the model screens out all the high potential tree species, in terms of stand growth, as the candidates for species selection and, then, calculates IRR for managing plantation forest stands for all the candidate tree species. The tree species of the highest IRR would be chosen as the one possessing the highest potential in terms of stand growth and profit. The model was applied to a case study for analyzing the site-specific suitability of 6 tree species in Taehwa University Forest of Seoul National University and the results are given in this paper.

It is evident that a financial feasibility study based on the economic analysis has been theoretically and practically accepted in the aspect of its adequacy. However, it is not easy to apply in the practical business affairs since there exist some difficulties on the economic analysis and the interpretation of the result because of the difficulty of the estimation of the discount rate. This study aims to suggest a method of the financial feasibility study based on the economic analysis. The results of this study are as follows. First, this study can increase the reliance and adequacy of the economic analysis result by suggesting a method of estimating the discount rate by means of the proxy ${\beta}$ method in the practical way. Second, this study can provide the overall frame of the financial feasibility study based on the economic analysis method (namely, Net Present Value Method internal rate of return, profit index method and payback period method)which use discount rate and cash flow. Third, this study can suggest an practical analysis skill required in each step of the financial feasibility study.

The purpose of this research is to suggest economic feasibility of cultivating Acer Mono by using profitability analysis to forest owners. To achieve this research objective, forest owner household survey with intensive cultivating has been conducted about a sap production on its age of tree. And input costs and sap production costs are calculated with silvicultural system from plant to regeneration cutting. Total income is the sum of its sap sales and thinning and regeneration cutting. The method of profitability analysis was used on the NPV(Net Present Value) and IRR(internal rate of return). Finally, when 3% discount rate is applied, NPV is about 59,436 thousand won and IRR value is 9.22% at this point. This result, therefore, proves that cultivating Acer Mono is economical feasibility to forest owners.

올해(2004년) 연말로 예정된 남북철도 연결이 동북아 지역의 물적교류에 미칠 영향에 관한 연구는 TSR, TCR. TMGR, TMR에 관한 연구와 함께 국내에 이미 상당한 수준 축척 되었지만 물적교류와 함께 동북아 교류협력에 또 한축을 이루고 있는 인적교류 즉 여객수송에 관한 연구는 거의 없는 실정이다. 본 연구에서는 인구가 조밀하고 경제성장속도가 빠른 서울↔북경 축에 국제 여객열차를 운행할 경우를 가정하여 기존의 항공$.$해운에서 철도로의 수요 전환량을 실제 설문조사를 통하여 구하고 이를 수송할 열차운행 계획을 세운다. 나아가 국제 여객열차 운영자의 입장에서 예상수입 및 비용을 현실성 있게 분석하고 수익성 여부도 유동성, 순현재 가치, 내부수익율 세가지로 검토하여 한$.$중간 국제 여객열차 운행의 가능성을 검증한다.

본 연구의 목적은 농촌진흥청 국립원예특작과학원 감귤시험장에서 개발된 감귤신품종인 하례조생의 개발의 기술가치를 평가하는 것이다. 이는 농업 R&D사업의 효율성과 실용성 제고를 위하여 이용될 수 있을 것이다. 분석결과에 따르면, 감귤신품종 개발에 따른 기술가치평가액은 할인율 수준에 따라 최소 638.7억 원 (할인율 10%)에서 최대 1,088.7억 원(할인율 6%), 평균 829.17억 원(할인율 8%)으로 추정되고, 내부수익율 IRR의 값은 가정했던 할인율(6%~10%)보다 훨씬 크고, 순현재가치(NPV)는 영보다 훨씬 크며, B/C 비율도 60 이상으로 나타나 신품종개발사업의 경제적 타당성은 있는 것으로 판단된다.
