The purpose of this study is to analyze willingness to pay (WTP) for organic agricultural products. To accomplish the objective of the study, a consumer survey was conducted. Based on the pilot survey results, parametric survival model was used to analyze the WTP for organic products. The estimation results showed that the WTP for organic agricultural products is 1.4-fold when compared with the conventional products, which is lower than the current price by about 30 percent. The analytical results also showed that such variables as gender, recognitions for organic agricultural products, and consumers' income have very significant effects on the WTP, and that there are no differences among WTPs by consumption goals. Based on major findings, the most effective countermeasure was suggested for expanding of organic food consumption through the premium reduction of organic products. Reducing the costs of production and distribution, supporting farmers' income by direct payment system were presented. Furthermore, it is needed to allocate more budget for promoting the consumption and distribution of organic agricultural products, and for enhancing conservation of agricultural environment.

농촌의 인구활력화, 지역경제 활성화, 농촌의 문화다양성, 농촌 가족사회의 유지, 그리고 농촌자원의 향상과 같은 다문화가족이 농촌사회에 미치는 영향 및 기여가치에 대한 WTP(Willingness to Pay)를 추정하기 위해, 농촌지역 41개 시 군에서 weibull model에 기초한 이중이선선택법으로 조사가 이루어졌다. 이어 추정모형을 개발하고 로지스틱(logistic)을 이용해 WTP를 추정하였다. 추정결과, 다문화가족의 기여가치 유지를 위해 농촌지역민이 평가한 WTP는 458억원이었고, 이것은 개개 농촌가구가 연간 13,840원을 지불할 수 있음을 의미한다. 비교준거로서 다문화가족 남편이 평가한 WTP는 502억원 이었고 이것은 개개 농촌가구가 연간 15,170원을 지불할 수 있음을 의미한다.

The objective of this study was to estimate social cost on rehabilitation of existing water pipes by investigating the willingness-to-pay (WTP) of residents at INJE County to avoid the loss and inconvenience of transportation and business resulting from the sudden failure and leaks of old water pipes. Contingent valuation method was used through conducting survey to 180 residents in Inche County, with questions of double-bounded dichotomous choice. The resulting WTP of residents at Inche was 7,682 won/month/household. The annual social cost could be estimated as 960 million won, which might be caused by the failure of the old water pipes at INJE County.

The objectives of this study were to analysis willingness to pay (WTP) for environmental-friendly agri-product (EFAP) food service of child-care centers. To analysis preference about EFAP and WTP, parent' survey were conducted residing in Asan city. The sample size of the survey is 143 respectively. As a result, most of parents really recognized that EFAP is good for their children as well as they want to change food material from general agri-product to EFAP. Moreover, additional willingness to pay fur EFAP food service is 8,360 won on average per month. Therefore, environmental-friendly agri-policy to be more focused on the promotion of the consumer's interests and food security needs.

To estimate the annual WTP for risk reduction of environmental problems such as outdoor and indoor air pollution, and drinking water contamination, a questionnaire survey was conducted by dichotomous contingent valuation method in Seoul. Several covariate models based on Turnbull, Weibull and Spike models were developed and applied to WTP estimation with uncertainty analysis. WTP estimates for risk reduction of air pollution were 13,000 won, 12,000 won, and 10,000 won per month in low-bounded Turnbull, Weibull and Spike models, respectively. The estimates for indoor air pollution were 17,000 won,20,000 won and 21,000 won and these for drinking water contamination were 10,000 won, 13,000 won and 14,000 won in each model, respectively. Goodness of fit for Weibull model was better than those for other models. WTP estimates for indoor air pollution were higher than those for other pollution problems.

본 연구의 목적은 국립과학관 상설전시관 입장료에 대해 관람객이 지불할 수 있는 수준을 조사하여 입장료의 가치를 추정하는 것이다. 이러한 추정은 국립과학관의 경영 효율성을 높이기 위해 입장 수익을 증대하는 것이 합리적인지 아닌지를 판단하는데 있어서 중요한 논거를 제시할 수 있다. 국립과천과학관을 방문한 관람객 250명을 대상으로 조건부가치추정법(CVM)을 활용하여 입장료에 대한 지불의사(WTP)를 분석한 결과, 평균 지불의사 금액은 성인 요금 8,447원, 어린이·청소년 요금 6,535원으로 현재의 국립과천과학관 상설전시관 입장요금 4,000원과 2,000원보다 각각 2배와 3배 이상 높게 추정되었다. 이러한 추정은 국립과학관 입장료를 체계화하고 국립과학관의 재정 자생력을 확보하는 기초 자료로 활용될 수 있을 뿐만 아니라, 나아가 양질의 공공전시서비스(국공립 과학관, 미술관, 박물관 등)를 효율적이고 효과적으로 국민에게 전달할 수 있는 방안을 모색하는데 도움이 될 수 있을 것이다.

본 연구는 말고기에 대한 소비자 수요와 지불의사액을 추정하는데 연구목적이 있다. 먼저 말고기에 대한 소비자 수요를 현재수요(current demand), 잠재추가수요(potential demand) 그리고 잠재신규수요(latent demand)로 구분하여 조사하였으며 로짓 모형을 이용하여 소비자 수요별 설명변수와의 유의성을 검토하였다. 다음으로 이선선택형 가상가치법(DC-CVM)을 이용하여 말고기에 대한 지불의사액을 추정하였다. 말고기에 대한 소비자 지불의사액은 한우 3등급 등심부위 가격의 67.8% 수준이었으며, 이들 지불의사액에 미치는 영향은 남자일수록, 연령이 낮을수록, 그리고 말고기에 대한 인지도가 높을수록 지불의사액이 높았다.

This paper investigated customers' willingness to pay (WTP) for the integrated news platform, which is a paid digital news service provided by Korean newspapers. The integrated news platform has been widely employed and regarded as an alternative to recover dramatically decreasing sales of newspapers since N-Screen era began. This study employed a conjoint analysis to examine WTP for the integrated news platform and its attributes. According to the results, WPT for the integrated news platform was estimated as 4543.6 won, which is only 30.3% of the real price. Digitalized newspaper and premium news were found to be significant attributes explaining customers' WTP. The results of this paper implies that present marketing strategies for the integrated news platform of Korean newspapers should be reconsidered and revised.

To assess the economic value of pharmaceutical therapy with Kremezin, we investigated the maximum amount of willingness-to-pay (WTP) of patients with chronic renal failure (CRF) for a hypothetical effect of Kremezin in delaying the initiation of dialysis treatments. A face-to-face survey was carried out in a sample of 141 CRF patients from 2 dialysis centers, composed of 82 hemodialysis patients, 38 peritoneal dialysis patients, and 21 non-dialysis CRF patients. Using a bidding game method with a starting point of 320,000 Won, which is the average monthly out-of-pocket payment for dialysis treatment, we asked the study subjects how much they would pay per month to receive Kremezin therapy. The mean out-of-pocket monthly WTP for Kremezin was 310,000, 430,000, and 520,000 Won (p<0.05, repeated one-way ANOVA)) when Kremezin delays the initiation of dialysis treatments by 1, 2, and 4 years. Significant correlation between the respondent's WTP and income $(r=0.266{\sim}0.368,\;p<0.05)$ confirmed the construct validity of the WTP instrument. Regression results showed that patients with a higher education, with diabetes as a major causes of CRF, and undergoing hemodialysis treatments tended to express higher WTP for Kremezin. The economic value of WTP from the perspective of patients varied from 310,000 to 520,000 Won depending on the effect size of Kremezin. The mean WTP was higher than 32,000 Won, only when the hypothetical effect of Kremezin in delaying the initiation of dialysis is for 2 years. This implies that Kremezin might be the preferred choice of therapy by CRF patients if it delays the initiation of dialysis treatment for at least 2 years.

Building deterioration reflects the degradation of basic building performance including structural performance, energy performance, durability, and safety, and it also includes perceived deterioration, which considers a user-based perspective. More than 50% of the existing buildings in Korea are over 15 years old and public buildings compose 2.5% of all buildings domestically. Therefore, there are several different problems, such as poor energy efficiency, structural performance, and safety. To address the challenges of increasing stock in deteriorated buildings, it is necessary to make decisions about reconstruction or renovation. In this study, we propose a new method to evaluate public building value with a contingent valuation method (CVM). By estimating willing-to-pay (WTP) from users of private buildings in similar situation with the public building, it is possible to compare market prices and calculate a correction factor to adjust the WTP data. Finally, we apply the correction factor to the WTP of a public building and estimate market price, willingness to pay (WTP). Finally, we apply the correction factor to willing to pay (WTP) of public building and estimate market price.
