This study aims to estimate and calculate the ability to pay (ATP) and the willingness to pay (WTP) of households for wastewater management services (IPAL), the relationship between ATP and WTP, and factors that affect WTP. The location of IPAL construction is in the area of Lampung Province, Indonesia. There are 158 selected households for this study. The study employs a purposive sampling method in which the characteristics of households are classified into 3 categories - former households, newcomer households who had come to this area and have no experience of using water supply services, and newcomer households who have experience of using water supply services such as PDAM. The results of this study are, ATP and WTP values were not always in the same direction. The highest ATP was for newcomer households with experience of water supply services but the WTP was the lowest, on the contrary, the lowest ATP was for former households, but the WTP was the highest. Furthermore, experience and cognitive reference are positively correlated with WTP. Service quality perception, education/knowledge of respondents about environmental conservation, and level of income correlate with WTP.

본 논문은 정보재화로서 개인정보의 특징과 개인정보에 대한 경제적 고찰을 통해 개인정보 침해의 부정적 효과를 방지하기 위한 지불의사 비용, 즉 Willingness To Pay(WTP)를 분석하였다. 개인정보 보호를 위한 지불의사비용 결정요인에 대한 학술적 연구는 아직 미흡한 현실이다. 따라서 본 논문에서는 개인정보 보호를 위한 지불의사비용에 영향을 미치는 요인을 이중양분선택법(double-bounded dichotomous choice)에 근거하여 개인정보 침해를 예방하기 위한 비용을 결정하는 요인을 찾고자 하였다.

This study investigates the factors affecting Korean consumers' willingness to pay (WTP) for domestic and organic agricultural, livestock, and processed food products. The findings reveal that obesity status, drinking frequency, and dining out frequency positively influence WTP for both domestic and organic products across all categories, while higher personal income, a convenience-seeking lifestyle, and the tendency to make shopping lists have a negative effect. The factors influencing WTP for organic products differ partially based on the country of origin, with dining out expenditure, disease symptoms, purchase of processed foods, and avoidance of risky foods show different impacts between domestic and imported organic products. The category- specific analysis shows that the perceived nutritional value of domestic products significantly affects WTP, except for livestock products. Safety certification preference has a mixed impact, lowering WTP for domestic agricultural and livestock products but increasing it for domestic organic livestock and processed foods. These results provide valuable insights for developing segmentation and differentiation strategies in the domestic agricultural market.

This study used the contingent valuation method to determine how much consumers would be willing to pay to improve their city-gas safety and what factors influence consumers' willingness-to-pay (WTP). To elicit this information a mail questionnaire was sent to a randomly selected sample of 2,400 residents who use the city-gas. The survey results showed that individuals were willing to pay $4,750{\pm}342.8$ won per month for the city-gas safety improvement. The aggregate annual WTP was estimated at 121.5~318.0 billion won. To better understand how individual's socio/demographic characteristics affect the WTP, Censored Tobit analysis was used. The results show that higher income, more gas use (cooking and heating), willingness to install a safety instrument significantly increase consumer's WTP.

The study was conducted to examine consumers' awareness and perceptions on forest certification and their willingness to buy and pay price premium for certified wood products especially for selected four wood products. A total of 136 residents in Seoul and Gyeonggi Province were interviewed in the autumn of 2008. Although only 24.3 percent of the consumers are aware of forest certification, 82.4 percent of the respondents recognized the need and significance of forest certification. In general, 77.2 percent of the respondents were willing to buy certified wood products. Majority of the respondents, 84 out of 136 respondents (61.8%) expressed their willingness to pay (WTP) from more than 0 percent to less than 10 percent. Consumers' average WTP for certified wood products was estimated to be 5.6 percent. From the results of the study, lower priced wood products, such as copier paper (WTP=9.8%) and wood frame (WTP=11.6%), have higher price premiums than high priced products, such as wood table (WTP=6.8%) and wood flooring (WTP=7.6%). In conclusion, there could be feasible markets for certified wood products in South Korea as four out of five consumer are willing to pay more for such products. For the forest certification system to be adopted and widely accepted, the perceptions of forest stakeholders including consumers should be further increased.

응답자들에 따라 지불의사액(willingness to pay : WTP) 조사에서 응답한 WTP에 대한 확신도, 즉 선호의 강도가 다를 수 있다. 본 연구는 선호강도의 정도에 대한 정보를 얻기 위해 응답자가 응답한 WTP에 대해 선호강도가 어떤지에 대한 응답을 이끌어 내었다. 선호강도를 반영한 WTP 자료의 분석을 위해 본 논문에서는 Type 3 토빗모형의 적용을 고려한다. 이 모형을 추정하기 위해서는 통상 동분산 및 이변량 정규성을 만족하는 오차항 구조를 가정한 모수적 2단계 추정법을 적용한다. 하지만 이 가정들이 만족되지 않는다면 추정치는 비일치적이게 된다. 동분산과 정규성 가설에 대해 검정한 결과 유의수준 1%에서 두 가정은 모두 기각되었다. 따라서 모수적 Type 3 토빗모형을 추정하는데 요구되는 가정은 너무 제약적이라 할 수 있다. 본 연구에서는 이 모수적 모형에 대한 대안으로 준모수적 Type 3 토빗모형을 적용한다. 분석결과 준모수적 추정은 모수적 추정보다 유의하게 우수하였으며, 더욱더 중요하게는 모수적 모형으로부터 계산된 평균 WTP 추정치는 준모수적 모형으로부터 계산된 것과 유의하게 다름을 알 수 있었다.

It will become more and more popular to use the long-term care facilities and home health care services with the chronic disease increasing. It depends on how much the consumers would pay and purchase the services. They might get more benefits from that kind of services than from ordinary hospitalization. So far, the study of determining the medical service price has focused most often on the efforts from the providers' view. But it must be reasonable to include the consumers' value for the service. This study was performed to assess WTP(Willingness to Pay) for home health care service in order to apply to the determination of nursing price in a reasonable manner. In this study, respondents were asked if they would pay for the service's intangible benefits under the four different types(open-ended minimum WTP, open-ended maximum WTP, bidding WTP, referendum WTP). The contingent valuation method is a potentially useful tool in understanding how people value the benefits of the service. As a result, average open-ended minimum WTP was W16,015 per day among 65 respondents. Average open-ended maximum WTP was W29,154 per day among 65 respondents. Average bidding WTP was W26,300 per day among 65 respondents. Average referendum WTP was W22,200 per day among 70 respondents. The results of regression analyses were also consistent with theoretical prediction, e.g., increasing WTP with consumers' value for the service, state of patients, and household income. This study demonstrated that it was more reasonable to consider the consumers' value in determining the services' price. In addition, a further study is needed to test the validity of this CV method and to determine a proper nursing price based on the consumers' view.

Blockchain can be highly secured by design and efficient for huge data so that many researchers and practitioners have been interested in blockchain in nature. The principles and applications of blockchain have been investigated by numerous studies and projects, however little is coincident regarding estimating about security investors' additional willingness to pay (WTP) and analyzing relationship with socio-economic characteristics of the investor for blockchain in the securities industry. This study surveyed on 1,000 heads of the household or homemakers that represents population well and estimated additional WTP using one-and-one-half-bounded (OOHB) dichotomous choice (DC) contingent valuation (CV) method. About 63% of respondents had additional WTP for blockchain. The mean WTP was KRW 48,206.92 and the median WTP was KRW 30,967.76. In addition to, the people who are high-income, highly-educated and having more financial asset were more likely to pay extra for their utility from using blockchain. The aggregated additional WTP was about 13% of the 2017 fiscal net income of the security industry. Consequently using blockchain, the strategic developing of securities targeting high-income, highly educated investors having more financial assets can increase commission income, which in turn can increase the company's revenues.

The contingent valuation method (CVM) was used along with a questionnaire survey and field research methods to analyze the factors affecting willingness to pay (WTP) for urban parks in Tai'an. The results indicated that roughly 50% of the residents visited the urban parks weekly. Doing physical exercises and viewing topped the list of activities. Residents of different characteristics had different WTPs for the service functions of urban parks. From the two surveys, 60.1% and 61.4% of residents would be willing to pay. The average individual WTPs were 42.2 $yuan{\cdot}a^{-1}$ and 43.1 $yuan{\cdot}a^{-1}$ in the two surveys, and the medianin dividual WTP was 20.0 $yuan{\cdot}a^{-1}$. WTP was mainly affected by satisfaction, and WTP value was mainly affected by education level and income. Other factors had some correlation, but none were significant. Finally, some useful suggestions and references were given to the government in order to enhance the urban park services proposal.
