To estimate the WTP(Willingness to Pay) for consistent maintenance of rural multi-cultural families' contribution worth such as vitality of rural population, regional economic vitalization, cultural diversity of rural, maintenance of rural family society, and diversity of rural resource, a questionnaire survey was conducted by double-bounded dichotomous choice method based on Weibull model in 41 city county of rural. A estimation models based on Tunball models were developed and applied to WTP estimation with logistic analysis. WTP estimates for consistent maintenance of multi-cultural contribution worth by rural resident was 458 hundred million won. It means that each rural household can pay 13,840 won per annual. WTP estimates assessed by multi-cultural families' husband as a criteria for comparison was 502 hundred million won. It means that each household can pay 15,170 won per annual.

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.

This study aims to determine the value of the willingness to pay(WTP) admission fees through surveying the level at which visitors to national science museums in Korea are willing to pay for admission fees. The determination helps objectively identify ways to substantially increase admission-based revenues, thereby enhancing managerial efficiency of national science museums. Using the contingent valuation method(CVM), we analyzed the WTP for admission fees of 250 visitors to Gwacheon National Science Museum. The statistical analysis revealed that the average amount of WTP was far higher than the current admission fees(4,000 won for adults and 2,000 won for children and adolescents). WTP of questionnaire respondents was normally distributed at the mean of 8,447 won for adult admission and 6,535 won for non-adult admission to Gwacheon National Science Museum. This result can be used as basic evidence to redetermine admission fees of national science museums and ultimately improve financial vitality.

This study aims at estimating the consumer's demand and willingness to pay(WTP) for horse meat in Korea. Three econometric models are employed to examine the multiple layers of the demand, including the current demand, the potential demand and latent demand. Findings indicate a substantial demand for horse meat. Dichotomous choice contingent valuation method is used to elicit the WTP. We assess the mean WTP for horse meat using a double-bounded logistic model. As a result, consumers are willing to pay at 67.8 percent of the beef prices of the third quality grade to purchase horse meat. And, for the factors that influence on WTP, only sex, age and recognition of horse meat are statistically significant.

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.

The purpose of this study is to survey on parents' preference and estimate parents' Willingness to pay(WTP) for after-school rural experience program in daegu city by choice experiment(CE). The results of this study are as follows; First, we divided after-school rural experience program into three types, namely: nature seeing, play exercise and learning experience. Second, the study has shown that parents prefer learning experience among those after-school rural experience programs. Among attributes which form a experience program, instructor certificates, consuming time and expense for participant are statistically effecting significant impact. Third, the result of estimation on willingness to pay for development of after-school rural experience program is as follow. The willingness to pay for learning experience is 6,337won, willingness to pay for instructor certificates is 14,102won and it for consuming time is 2,926won. Therefore, composition centering learning experience is better and instructor who has expert certificate is required. It is much better to compose that the consuming time is longer and the expense for experience is lower. But there is limitation because this survey was conducted based on an assumption, so it could read over estimation problem. The result of this study may provide useful information to develop after-school rural experience program using rural resources and to improve rural tourism policy.
