This study aims at integrating economic tools and remote sensing for environmental impact valuation of the Isahaya Bay Wetland (IBW). In doing so, we have used potential behavioral economic valuation technique: contingent valuation method and satellite remote sensing technique: land cover mapping. From the results of the study, we are able to bracket a range of values from (22 to 200 billion yen) for arriving at the true economic value lost due to the initiation of reclamation project on the IBW and would provide a new dimension to get nearer to the more accurate environmental impact assessment.

Before the EIA was established in the Federal Republic of Germany, the impact mitigation principle - a planning instrument, which has its legal foundation in the German nature conservation legislation already had {and still has} the function to valuate environmental impacts. The valuation principles and methods which have been developed in correlation to this instrument are now also used in the EIA. Particularly for the valuation of alternating effects on the different ecological landscape functions and for the valuation of ecological mitigation and compensation measures this valuation methods are used. These methods base on a special kind of modelling nature and environment Following the aim of the nature conservation act, which is to save the capacity of the landscape to perform its essential functions, not the ecological factors (soil, water, air etc.) itselfs are evaluated but the ecological functions of the landscape, which are based on the ecological factors.

The objective of this research was to estimate residents' willingness-to-pay using contingent valuation method and to investigate their environmental sensibilities prior to conduct the costbenefit analysis on the watershed management program of integrated sewerage construction and operation in the catchment of Dam Chung-Ju. A set of questionnaire was prepared and asked to 1,200 residents at downstream area as well as upstream area of Dam Chung-Ju. As a result, environmental sensibility of the residents living in the catchment of upstream of Lake Chung-Ju seemed very high. However, the substantial practice in their own life for conserving their environment was inactive, although residents' efforts trying to collect and dispose garbages in separate containers and to minimize the waste discharge load were actually made. The willingness-to-pay on each month for 20 years was estimated as 4,841 wons for the openended question and 3,411 wons for the close-ended question. Factorial analysis was also performed to obtain correlation among the questions asked. Seven groups of the correlated questions were identified and their contribution to the estimated willingness-to-pay was analyzed.

The primary objective of the current study is to ascertain the effect of transparency and disclosure (T&D) on the value of banks operating in the Indian banking sector. It also includes finding the moderating impact of financial distress (FD) and environmental, social, and governance (ESG) on the association between T&D and the valuation of banks. The study employs Panel data analysis (PDA) to analyze data and produce novel results thereafter. The authors of the study have considered using data of secondary nature which is sourced from banks operating in the Indian banking industry. Data in the current study has been considered for ten financial years, i.e., 2010 to 2019. The results reveal that T&D positively impacts a firm's valuation. We have also found evidence that financial distress and ESG (Environmental, Social, and Governance) significantly impact the value of firms under the influence of T&D. As far as we are aware, no study of this kind has been done yet in any developing nation to determine the effect that T&D, FD, and ESG have on the value of Indian banks. This paper can help future researchers in their respective studies that will involve the study variables (FD, T&D, and ESG).

As United Nation (UN) declared 2010 to be the International Year of Biodiversity, the biodiversity issue has gained much attention since the issue of climate changes. Also, related researches for protecting and conserving the biodiversity are accompanied in the world. In this study, National Ecology Information is obtained from Ministry of Environment and Korea Forest Service and is utilized to valuate biodiversity and ecosystem services in Pyeongchang, Kangwon-do in Korea. For this, they are categorized into direct- or indirect-use value and nonuse value. Research results show that the biodiversity and ecosystem services in Pyeongchang are assessed as 2 trillion and 460 billion won. From this research, we evaluate the economic value of biodiversity and ecosystem services, and also suggest the possibility to utilize them as basic information for a decision making to establish the biodiversity protection plan.

진술선호법의 가상적 지불상황으로 초래되는 가상편의(hypothetical bias)는 설문 응답자에게 사회규범적 부담으로 작용하여 설문 응답에 영향을 줄 수 있다. 본 연구에서는 도심하천복원의 경제적 편익을 추정하기 위해 전통적으로 사용되고 있는 주관적 질문과 함께 객과화된 질문을 적용하여 가상적 편의(사회규범편의)를 검정하였다. 대전광역시의 하천이 복원되는 사례를 이용하여 전국의 응답자 1,000명을 대상으로 데이터를 수집하여 조건부가치평가법(CV)과 선택실험(CE)을 함께 적용하여 지불의사액을 추정하였다. 사회규범편의를 검정하는 방법으로 관련 문헌에서 일반적으로 쓰이는 표본분할과 파라미터화 방법을 함께 적용하여 그 함의를 비교하였다. 전통적인 방법으로 추정된 하천복원의 한계가치는 CV의 경우 10,500원, CE의 경우 수질 개선 18,600원, 하천내부 개선 2,200원, 하천주변 개선 8,900원, 생물다양성 개선 5,800원으로 추정되었다. 검정 결과에 의하면 응답자들의 선호도 이질성을 설명하는 원인으로서 질문의 차이를 파라미터화하여 모형에 포함시킬 경우에는 가치평가기법의 차이에 관계없이 사회규범편의가 5% 수준에서 모두 유의하게 나타났다. 반면, 질문의 유형에 따라 데이터가 독립적으로 분석되는 표본분할의 경우 대부분의 경우에서 사회규범편의가 유의하지 않았다. 비록, 본 연구에서 Cheap-talk가 사전에 적용되어 가상적 편의가 1차적으로 걸러졌을 가능성이 있겠지만, 검정법에 따라서 전혀 다른 결론이 도출될 수 있어서 앞으로 주의가 요구된다. 실질적 효과성 차원에서 사회규범편의를 검정하는 표본분할의 사용을 권한다. 특히, 사회규범이 강한 상황에서는 Cheap-talk 이후에도 가상편의가 강하게 잔존할 가능성이 높기 때문에 향후 비시장가치평가에서 객관적 질문의 역할이 강조된다.

Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a Lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem or landscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

Purpose - This paper examines the value relevance of socially responsible activities in the Korean retail firms. Recent studies predict positive relationships between socially responsible activities and the value of corporation. Research design, data, and methodology - We use the environmental score, social score, governance score and the sum of these three scores to represent a fim's effectiveness of socially responsible activities. These scores are published by the Korean Corporate Governance Service. This paper adopts a share price valuation model to evaluate the effect of socially responsible activities on a firm's share price, which controls for the book value of assets and current earnings. The ordinary least square method is employed to examine the relationship. The sample of Korea retail firms is examined from 2011 to 2016. We also conduct sub-sample analysis based on the categorization of chaebol affiliates and non-chaebol affiliates. Results - The entire sample analysis finds neither negatively nor positively significant relationship between socially responsible activities and the value of a corporation. In contrast, our examinations find a significantly positive valuation effect of social score within non-chaebol retail firms. Conclusions - The results weakly support the positive valuation effect of socially responsible activities. The results are consistent with recent studies that highlight heterogeneous effects of socially responsible activities on corporate policies and valuation.

This paper aims to design a policy-assessment tool liking the Environmental Impact Assessment(EIA) and the Cost Benefit Analysis (CBA). As a step towards the incorporation of environmental and economic considerations, the approach used herein takes the form of integrating quantitative information on environmental benefits and costs associated with implementing the project into the existing framework of the EIA. Our case study is an project appraisal of a solar energy plant. It is confirmed that the technique is operational, however, there are certain limitations for a complete assessment. The difficulty mainly originated from the omission of important information from each step of the valuation process. Alternatively stated, some environmental services are not identified, nor quantified, and nor monetized in the process. More case studies are warranted in the future along with elaboration in methodology of techniques. In addition, the construction of a database on environmental values will be required to accumulate reliable and systematized data. These are the necessary conditions to improving quality in application of techniques as well as providing comprehensive and balanced information to decision makers.
