Environmental concern has been an important issue for a few decades, and the extent of consumer demand for eco-friendly consumption has been increased. This study seeks to investigate consumers' willingness to pay (WTP) a premium for eco-friendly cosmetics. This study evaluates how much more a consumer is willing to pay for eco-friendly cosmetics and examines significant factors influencing consumers' WTP for eco-friendly cosmetics. Consumers' WTP is measured using four different ecofriendly cosmetics: low-priced skin care cosmetics, low-priced makeup cosmetics, high-priced skin care cosmetics, and high-priced makeup cosmetics. This study uses the contingent valuation method (CVM) to estimate consumer's WTP for eco-friendly cosmetics. Survey questions were designed using both dichotomous choice and payment card method of CVM. Through face to face interviews and on-line surveys, the data were collected from women between 20 and 49 years old residing in Seoul and Kyeonggi area, Korea, in May 2010. A total of 226 questionnaires (132 from interviews and 94 from on-line) were included for the analytical sample in this study. The data were analyzed using descriptive analysis, T-test and Log-Logit analysis. The findings are as follows: First, the WTP measured by dichotomous choice method was estimated using the Log-Logit analysis. The results showed that the estimated WTP for low-priced skin care cosmetics was 19,152 won, which was 27.7% higher than the reference price, 15,000 won. For low-priced makeup cosmetics, the estimated WTP was 18,524 won, and its green premium was 21.0%. The estimated WTP for high-priced skin care cosmetics was 59,128 won, which was 18.3% higher than the reference price, 50,000 won. For high-priced makeup cosmetics was 57,666 won, and its green premium was 15.3%. Second, the WTP measure by payment card method was estimated using descriptive analysis. The results showed that the respondents were willing to pay 17,955 won for low-priced skin care cosmetics, which was 19.7% higher than the reference price, 15,000 won and 17,595 won for low-priced makeup cosmetics, which was 17.3% higher than the reference price. For high-priced skin care cosmetics, the average WTP was 56,950 won which was 13.9% higher than the reference price, 50,000 won. For high-priced makeup cosmetics, the average WTP was 55,650 won, which was 11.3% higher than the reference price. Overall, the WTP was higher in order of low-priced skin care, low-priced makeup, high-priced skin care, and high-priced makeup. It means that consumers decide degree of premium based on the price and the attributes of eco-friendly products. Third, the findings showed that age, monthly income, and having children or not were statistically significant factors that influenced consumers' willingness to pay for eco-friendly cosmetics. Other explanatory variables such as education, marital status, job, purchase experience of eco-friendly products, and environmental concerns did not show any statistical significance. The major contribution of this study is the investigation of the value of green attributes of the products by using CVM. Unlike most previous researches, this research used two methods of CVM, the dichotomous choice and the payment card, so it enhanced the reliability of research. According to this study, consumers showed price sensitivity when they pay green premium. These findings can be used as useful information to establish marketing strategies for green cosmetics.

The paper is to estimate willingness-to-pay (WTP) for tap water quality improvement in Busan, using parametric approach in contingent valuation method(CVM). For parametric approach linear logit model and log logit model are employed in double-bounded dichotomous choice format of CVM. For the reliability and the validity of contingent valuation method a survey was conducted for 665 respondents, who were sampled by stratified random sampling method, by personal interview method. The result of mean WTP for the tap water quality improvement in Busan was estimated to be 3,687 won and 3,660 won per month per household, while median WTP being 1,884 won and 1,892 won per month per household, respectively by linear logit model and log logit model. Provided that our sample is broadly representative of the Busan's population, an estimate of the annual aggregated benefit of residential water improvement for all Busan households is approximately 29.7 billion won to 29.8 billion won based on median WTP.

The two competing underlying mechanisms of anchoring, anchoring-and-adjustment and selective accessibility, have very different managerial implications for the effect of price as an anchor on willingness-to-pay (WTP). To clarify their relative roles in inducing the anchoring effect, path analysis modeling in which two paths are included in a single model was utilized. The first path proceeds directly from anchor price to WTP, representing anchor-and-adjustment. The second path, representing selective accessibility, includes a mediator formed by various explanatory variables of WTP. The results consistently show that only the direct path, anchoring-and-adjustment, is significant. The results also show that the level of available product information has no significant moderation effect on both of the paths, which implies the robustness of the result with respect to information level.

According to rapid increase of the population of senior citizens, there has been growing concern of Long-Tenn Care(LTC) services recently. Long-Tenn Care services, however, haven't been established systematically in Korea and the supply of LTC services is not sufficient despite the increase in the current social demand. This study aims to estimate the 'Willingness to Pay(WTP)' for LTC insurance which the government plans to introduce by means of social insurance, using Contingent Valuation Method(CYM). In addition, this study analyzes the factors affecting WTP for LTC insurance. An interview survey was carried out to derive WTP for LTC from 450 people who lived in Seoul aged 20 and above during the period from 16th to 21st of June 2003. Double-Bounded Dichotomous Choice Method was applied among several CVMs available to estimate both use value and no-use value of goods. There was pilot survey carried out prior to the main survey. The results show that the average monthly. WTP for LTC provided in home and residential setting is 18,192Won and 19,293Won, respectively. In the case of home care, WTP goes higher depending on reliability of LTC insurance policy and need for LTC insurance, as well as marital status, education and average monthly income. On the contrary, WTP is conversely affected by higher age and higher bids. In the case of institutional care, the factors affecting WTP are similar to those of home care, except age. This study followed NOAA's suggestions generally and the value derived through survey could be reliable. However, there can be the least bias in the process of survey because the CVM should be used under the supposed circumstances. Despite those limitations, it can be concluded that the amount the citizens are willing to pay for LTC is high enough to meet the costs needed to provide LTC.

비시장재의 변화에 의한 후생변화 측정치로서 쓰이는 지불의사(WTP)와 수용의사(WTA) 개념은 경제이론적으로는 소득효과가 크지 않다면 서로 크게 다르지 않을 것이라고 예측되고 있다. 그러나 실증분석결과들은 WTA 측정치가 WTP의 측정치보다 훨씬 큰 것으로 관찰되고 있다. 본 연구는 우리나라에서는 처음으로 실험시장접근법을 사용하여 비시장재의 하나인 먹는 물에 잔류가능성이 있는 유해물질(비소, 납, 트리할로메탄 중의 하나)로부터의 건강위험변화에 대한 WTP와 WTA를 측정하고 이 두 측정치에 차이가 존재하는지 실증적으로 분석하였다. 대학생들 15명씩의 참가자들을 대상으로 총 여섯 번의 실험시장을 개설하였다. 시장거래경험의 유무에 따른 차이를 검증하고자 사적 시장재인 캔디바 실험경매도 도입하였고, 반복경험에 따른 학습효과를 관찰하기 위하여 20번의 실험경매를 시도하였고, 정보제공효과를 관찰하기 위하여 10번째 경매 후에 객관적 건강위험에 관한 확률정보를 제공하였다. 시장재 비시장재의 구분없이 첫 번째 실험경매에서는 WTA가 통계적으로 유의하게 WTP를 초과하였다. 실험경매가 진행됨에 따라 사적 시장재는 WTA와 WTP의 차이가 사라지고 시장평균가격에 수렴하였다. 그러나 비시장재인 건강위험변화에 대한 결과는 혼재되어 있었다. 건강위험이 가장 큰 비소에 대해서는 건강위험 감소에 대한 WTP가 건강위험 증가에 대한 WTA보다 통계적으로 유의하게 적었다. 반면에 건강위험이 상대적으로 적은 납과 트리할로메탄에 대해서는 WTP와 WTA의 평균이 같다는 귀무가설을 기각할 수 없었다. 실험참가자들은 실험경매 중간에 제공된 건강위험정보에 대해 합리적으로 반응하였고, 실험경매가 진행됨에 따라 경험획득에 의한 학습효과도 긍정적이었다. WTP는 실험 초반에 학습효과가 주로 관찰된 반면에 WTA 측정치는 실험경매 후반에 학습효과가 관찰되었다.

Contingent valuation method(hereafter CVM) is generally believed to be one of the most popular methods used for quantifying the value of non-market goods or services particularly by asking respondents of willingness to pay. This study deals with how to use CVM in calculating the value of mobile telephone service by suggesting methodology of estimation and eliminating biases. This study represents an attempt to estimate the WTP(Willingness To Pay) of the mobile telephone service using the face-to-face interview which is the qualitative technique is used. In this study, by using the single bound dichotomous choice model(SBDC) in order to analyze the valuation of mobile telephone service, WTP was estimated. Also we analyze the factors to pay for mobile service in which it becomes the important factor of demanding services. We used logit model. In order to provide robust estimates of WTP, we have used the Method of Montecarlo Simulation. Consequently, consumers showed that WTP about the mobile communications service is generally high. And it could know that the WTP will fell down as the specialized knowledge about the mobile communications frequency was high. It will be able to become the important part to not only the business carrier but also the policy maker to estimate the economic value of mobile telephone service.

전력은 인간생존에 있어 기본적인 요소이다. 본 논문에서는 주택용 전력에 대한 가구의 지불의사액(WTP)을 분석하고자 한다. 주택용 전력에 대한 WTP는 전력의 실제 가격과 추가적인 WTP의 합으로 정의된다. 전자는 시장에서 쉽게 관측되지만, 후자는 시장에서 관측이 불가능하므로 직접적인 가구조사를 통해 추정해야만 한다. 이를 위해 2010년 11월 전국 1,000가구를 대상으로 조사를 실시하였다. 분석 결과 주택용 전력 한 단위에 대한 추가적인 평균 WTP는 11.24원/kWh로 나타났다. 조사시점인 2010년 주택용 전력 평균가격은 98.07원/kWh이므로 주택용 전력에 대한 경제적 편익은 이 둘의 합계인 109.31원/kWh으로 추정된다. 이 값은 주택용 전력 1kWh 공급비용과 비교할 수 있을 것이다.
