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.

본고는 산출물 시장에 있어서 독점적으로 행동하는 기업을 고려하여 담보(유담보 융자, 무담보융자)에 의한 차입계약이 차주인 기업의 비용최소화를 통해 비용함수의 형태를 결정하는 모델을 구축하였다. 또한 기업이 금융시장에서의 차입계약이 산출물시장에서 시장균형과 경제후생에 미치는 영향에 대한 분석을 통하여 자기자본이 열악한 기업이 금융기관으로부터 유담보융자에 의해 차입을 실시하면 담보의 범위 내에서 신용을 받을 수 밖에 없는 차입제약에 직면하게 된다는 사실을 증명하였다. 따라서 기업이 생산요소인 자본재를 담보로 설정할 때 생산 요소의 투입비율에 왜곡현상이 발생하며 기업이 금리가 높은 무담보 융자에 의해 대출행위가 이루어지면 한계비용은 상승하기 때문에 기업은 자기이윤을 최대화하는 차입계약을 선택하게 된다. 그러나 기업이 차입계약을 선택할 경우 소비자와 경제전체에 바람직한 현상은 아니며 전체적으로 경제후생을 악화시킨다는 것이 본고의 이론분석을 통한 결과로 볼 수 있다.

The main objective of this study is to analyze problems of the Country of Origin Labeling(COOL) in small live fish(SLF) trade by applying the asymmetric information theory which is called ${\ulcorner}$Lemon Market Theory${\lrcorner}$. The purpose of importing SLF is to enhance fishing household income and import substitution effect as well. SLF importation is quite different in its nature from importing general fish and fish products for final/direct consumption. SLF are imported for the purpose of domestic aquaculture and naturalization where domestic production/supply of SLF is less than domestic demand for or such species are not native to Korean waters. Information asymmetric problems arise even in SLF trade as the same way in general goods and services. However, the information asymmetry issues in SLF trade are much more complex than non-living goods because SLF are traded in the live state. To alleviate such problems the Korean government initiated the general COOL scheme to imported SLF. However, many experts argues that such policy on SLF would not be appropriate because of SLF's very nature. Applying the lemon market theory, we can analyze how information discovery schemes are able to signal correct information to SLF trading parties and to result in more symmetric information in SLF trade markets. This research carried out a case study about small live eel(SLF) trade and its farming. The results showed that applying the COOL to small live eels just right upon coming into fish farms tends to increase substantially fish farmer's income and at the same time to lower unnecessary transaction costs. In particular, such transaction costs by imposing simply the general COOL on SLF may easily outweigh its benefits. For instance, to resolve the problems, the Korean ministry of agriculture and forestry(KMAF) has developed a quite different COOL rules from the general ones and has applied them to imported live cattle and medium/small livestocks. The KMAF's differentiated COOL policy on some imported livestocks may be a good case which can be applied to imported SLF. In addition to the differentiated COOL on SLF, Sanitary and Phytosanitary (SPS) and traceability system would play crucial complementary roles in alleviating information asymmetry problems in SLF trade. Advanced fisheries tend to strengthen their SPS system rather than to adopt the general comprehensive COOL schemes into imported SLF trades and domestic market exchanges.

As growing importance and concern of waterfront, we have tried to study its landscape, accessibility, landuse and so on as well as its environmentally sound and sustainable development. In fact we had been under the false thought that it always gaves what we wanted, and it was neglected in its economic value. This paper/looks at one alternative, the non-market value generated by management of waterfront as public resources. We consider the question : how much are people willing to pay to improve, how much are people want to improve\ulcorner The contigent valuation method was implemented during Sep. 9 to 14 in 3 beaches ; haeundae, Gwanganri, Songjeong. They are representative waterfronts which have been widely known and visited. We find out that households are willing to pay about 12,000-16,000 den per year for improving nature elements and inviting more valuable functions about 3 beaches. Especially Ive pay attention to difference between cognitive and comprehensive satisfaction 3 beaches and their substructural factors satisfaction such as natural environment, public facilities, recreational facilities and etc.

Purpose - The purpose of this paper is to examine the welfare effects of standards harmonization between technologically asymmetric countries, and to determine optimal harmonization strategies for a country with mid-level technological advancement. Design/methodology - Following Salop's circular city model (Salop, 1979), this study constructs a simple, horizontally-differentiated oligopoly model in which three firms and three countries exist. Each country adopts different compatibility standards and each firm incurs conversion costs for foreign market access due to differences in standards. The conversion costs are related to technology; standards harmonization removes these costs between participating countries. The paper considers three cases: i) no harmonization; ii) harmonization with the more technologically-advanced country and iii) harmonization with the less technologically-advanced country. Findings - The paper first considers a scenario in which all three firms occupy some share of the market in each country. It shows that standards harmonization with both the technologically moreor less-advanced country always increases consumer surplus and social welfare. In addition, the producer surplus will increase if the harmonization partner has a higher technology level, whereas it may decrease if the partner has a lower technology level. It also shows that if most domestic export goods are in sectors with conversion costs above a certain level, harmonizing standards with a technologically more-advanced country should be prioritized. Such strategies, moreover, should be emphasized when there exists a large technology gap among countries. Lastly, the paper considers another scenario, in which harmonization leads to the foreclosure of the non-member firm from the member countries' markets. It shows that harmonization improves the social welfare of a mid-level technology country regardless of its partner's technology. It also shows that the country should prioritize harmonization with the technologically less-advanced country. Originality/value - Though some of the existing studies consider the welfare effects of harmonization, their main assumption is that firms have the same conversion technology. Since complying with standards often requires substantial technological advancement and technical expertise, harmonization of compatibility standards between countries with gaps in technological ability carries different implications. This paper investigates the welfare effects of this harmonization and determines an optimal harmonization strategy while considering technological asymmetry among countries in standards compliance.

지구 온난화 현상 이후, 지구환경 변화에 따른 자연 재해는 세계적 규모의 대형 참사로 이어지고 있다. 그중에서도 특히 폭풍해일에 따른 피해가 크게 늘고 있으며, 이에 관한 많은 연구가 진행되고 있다. 우리나라도 예외가 아니어서, 2003년 태풍 '매미' 등이 한반도에 상륙하면서 그로 인한 폭풍해일과 침수 피해로 큰 타격을 입었는데, 특히 마산 지역의 침수는 그 피해 정도와 범위가 가장 막대했다. 이에 따라 국내에서도 향후 폭풍해일 발생에 대한 철저한 대비책 마련의 필요성이 제기되었다. 이에 본 연구는 항만 재해방지시설 건설 시 편익액 산정에 사용되는 대표적인 두 가지 방법론, 즉 비시장 재화의 가치를 추정하는 조건부가치측정법(CVM)과 홍수나 댐 등의 사업에서 주로 이루어져왔던 다차원 홍수피해산정기법(MD-FDA)을 이용하여 마산항 폭풍해일 발생 시 피해액의 편익을 산정, 비교하고자 하였다. 이에 30년 비용의 편익액을 추정한 결과, 조건부가치측정법(CVM)은 2조5689억 원, 다차원홍수피해산정방법(MD-FDA)은 2조9596억 원으로 나타나 재해방지시설의 편익액 차이는 크지 않았다. 하지만 이를 토대로 재해방지시설에 대한 편익 산정에 있어 다차원홍수피해산정방법(MD-FDA)이 이미 비시장 재화를 대상으로 검증받은 방법인 조건부가치측정법(CVM)을 대신할 수 있는 방법인지는 추후 심층검증을 통하여 알아볼 필요성이 있을 것으로 판단된다.
