이 연구는 파각란 선별기 도입을 비용 편익분석 목적으로 수행되었다. 계란 파각란 선별기를 도입할 때의 총수입과 총비용 평가액의 추정결과는 다음과 같다. 총비용의 경우 구입가격, 고정비용 및 유동비용의 합계로 나타내었고, 할인율에 따라 5%, 10%일 때 각각 232,904천원과 242,904천원으로 산정되었다. 계란 파각란 선별기 평가액은 할인율에 따라 228,543천원(할인율 5%인 경우)과 218,543천원(할인율 10%인 경우)으로 추정되었다(Table 6). 파각란 선별기 기술가치에 대한 평가는 B/C비율, 순현재가치(NPV), 내부수익율(IRR)의 값으로 판단되었고, 내부수익율 IRR의 값은 가정했던 할인율보다 훨씬 높게 나타났고, 순현재가치도 0보다 큰 값으로 나타났으며, B/C비율도 1.0 이상으로 나타나 경제적 타당성을 가지는 것으로 판단되었다(Table 7).

Financial risks associated with capital investments are often measured with different feasibility indicators such as the net present value (NPV), the internal rate of return (IRR), the payback period (PBP), and the benefit-cost ratio (BCR). This paper aims at demonstrating practical applications of probabilistic feasibility analysis techniques for an integrated feasibility evaluation of the IRR and PBP. The IRR and PBP are concurrently analyzed in order to measure the profitability and liquidity, respectively, of a cash flow. The cash flow data of a real wind turbine project is used in the study. The presented approach consists of two phases. First, two newly reported analysis techniques are used to carry out a series of what-if analyses for the IRR and PBP. Second, the relationship between the IRR and PBP is identified using Monte Carlo simulation. The results demonstrate that the integrated feasibility evaluation of stochastic cash flows becomes a more viable option with the aide of newly developed probabilistic analysis techniques. It is also shown that the relationship between the IRR and PBP for the wind turbine project can be used as a predictive model for the actual IRR at the end of the service life based on the actual PBP of the project early in the service life.

본 연구는 최근의 금속가격변화를 고려한 36개의 시나리오를 작성하고 이에 대하여 망간단괴 채광, 제련의 경제성 평가를 수행하였다. 각 시나리오는 낙관/중립/비관의 채광 및 제련 비용전망과 2가지 생산규모, 그리고 6가지 금속가격 전망을 조합하여 작성되었다. 낙관/중립 비용전망에 따른 대부분의 시나리오에서 긍정적인 경제성 평가 결과가 도출되었다. 예로 300만 건톤의 망간단괴 채광의 경우, 중립적인 비용전망을 취하고 2007년 전반기의 금속가격을 가정하면 37.1%의 내부수익률을 얻는 것으로 나타났다.

본 연구는 해외조림을 통한 목재의 안정적 확보를 기하기 위하여 태국을 대상으로 투자환경과 수익성 분석을 하였다. 연구결과 태국은 정책적으로 산림률을 현재 25%에서 40%로 유지하려고 노력하고 있기 때문에 조림을 널리 장려하고 있으며, 조림과 목가공산업(합판, 베니어, Chip board, Hard board)은 최소한의 투자요건을 요구하는 업종으로 구분하고 있어 다른 분야보다 상대적으로 유리한 입장이다. 태국에서 현재 가장 역점을 두고 있는 조림수종은 유칼리로서 특히 펄프용으로 이용할 경우 유칼리의 벌기령은 4~5년으로서 매우 짧고 IRR도 29.1~59.3%로 매우 높게 나타났다.

국내 석탄화력발전에서 발생되는 바닥재 재활용의 경제성을 평가하고자 신설 500 MW${\times}$2기 유연탄 화력발전설비를 대상으로 바닥재 재활용이 가능한 건식처리시스템 도입의 경제성을 충수중력식 습식처리시스템과 비교하여 검토하였다. 신규발전설비에 건식처리시스템 도입 시 시설투자비는 습식처리시스템의 약 150% 수준으로 초기투자비는 더 소요되나, 바닥재 재활용을 통한 판매이익을 고려한 연간시설운영비는 습식처리시스템의 약 17%까지 절감되는 것으로 예측하였다. 이를 기초로 경제성 분석을 수행한 결과 건식처리시스템 도입 시 추가로 소요되는 초기투자비는 4.8년에 회수가 가능하며 투자이익률은 21.1%로 평가되었다.

This study attempts to suggest an economic analysis model for SNG projects, which can reflect the future uncertainty objectively and applies the real option valuation incorporating the flexible investment decision. Based on this analysis model, net present value and internal rate of return were estimated by using preliminary feasibility study report of SNG project. And economic evaluation of SNG project was performed with real option valuation using binomial option model. Through this, the difference of analysis results between the real option valuation model and the discounted cash flow model were compared and the usefulness of the real option valuation model was confirmed. From the actual proof analysis, it is confirmed that the real option valuation model showed higher SNG project value than the discounted cash flow model did. It was confirmed that by applying the real option valuation model, economic analysis can be performed on not only the current straightforward SNG project, but also various future portfolios having options such as expansion, modification, or decommission.

This study seeks to examine the main factors, external and internal to the bank, that enhance bank lending. Bank lending is one of the connecting bridges in sustaining society. Internal factors consist of ROA, DPK, and CAR. External factors are economic growth and interest rate of Bank Indonesia. The population of this research consists of traditional commercial banks listed on the IDX over the 2014-2017 period. Samples were chosen by purposive sampling method. This study uses secondary data with 56 samples; data analysis uses multiple linear regression. The findings of the study show that internal factors have a greater impact on increasing bank lending than external factors. The main variable among internal factors that influences increase in bank lending is ROA. DPK is the internal factor with the smallest impact on increasing bank lending. The implication of the study is that determining the bank lending should take more account of CAR, DPK, ROA, BI interest rates, and economic growth in making decisions about the amount of lending. These variables can only have a slight effect on increasing lending, though. Besides, internal factors such as NPL, LDR or non-economic factors also need to be considered in channeling bank credit.

경제성 분석에 의한 재무타당성 분석은 이론적으로나 실무적으로 그 타당성이 인정되고 있으나, 할인율 추정이 어려운 관계로 경제성 분석과 결과해석이 실무적으로 쉽지 않다. 따라서 본 연구는 신규호텔 건설 시 경제성 분석에 의한 재무타당성 분석의 구체적인 틀과 실무적용방법 및 기술을 제시하는데 근본적인 목적을 두고 연구하였다. 연구의 결과, 첫째, 대용베타방식에 의한 할인율(자본비용)을 실무적으로 추정하는 방식을 제시하여 경제성 분석결과에 대한 신뢰성과 타당성을 증대시킬 수 있었다. 둘째, 할인율과 현금흐름을 이용한 경제성 분석기법(순현가법, 내부수익율법, 수익성지수법 등)에 의한 재무타당성 분석의 전체적인 틀을 설명할 수 있었다. 셋째, 재무타당성 분석의 각 단계에서 요구되는 실무적인 분석기술을 제시할 수 있었다.

The economic feasibility analysis including benefit-cost ratio and internal rate of return of a land consolidation and on-farm development project was mainly depended upon the direct benefits and costs arising during project life. Therefore the projects were neglected in allocating the government's financial funds and loans on account of the low economic rate of return of the project. Accordingly the extended benefit-cost analysis method should be introduced and adapted to cover not only the benefit s such as non-market values of environmental and food security fun ct ions of the project but also market values of the project outputs. The main purposes of this study are (1) to prepare a guide line for economic feasibility analysis based on the IBRD and ADB guidelines, (2) to estimate the benefits from productivity increase, labor saving, savings of O&M cost of farm mechanization and project facilities, savings of farmer's burden for their public health, increasing environmental and public functional value of paddy fields, improving food security condition and formation of peaceful and uncontroversial rural society by implementing the land consolidation and on-farm development, (3) to introduce the newly adapted analytical method as the extended benefit cost analysis which could make possible to be included the values of non-market goods such as the food security and the environmental public function of paddy fields. To carry out this study, the existing publications on the guidelines for economic agricultural projects were reviewed and consultation was made with a For the post evaluation study of the land consolidation and on-farm development project, field survey in Jigok and other comparative area were made to get available information. According to the project completion report, Jigok land consolidation and on-farm development project has 55ha of benefit area out of 69ha of gross area. The project was started in November 11th, 2000 and completed october 30th, 2001. The total project costs were amounted to 2,548 million won and the annual project benefits were estimated at 335million won evaluated by domestic market prices. The ERR(Economic Rate of Return) and SRR(Social Rate of Return) of the project based on the shadow pricing system were estimated at 4.4% and 16% respectively. On the other hand, the ERR and SRR based on the domestic market value system were amounted to 6.37% and 14.62%. In conclusion, Korean land consolidation and on-farm development projects have not carried out from the view point of economic rate of return under shadow pricing system but from the view point of domestic pricing system. For the future feasibility studies on land consolidation projects have to be carried out including the non-market values as environmental and food security function of the projects.
