This study is to investigate consumers' acceptance and their willingness to pay for clothes made of materials with low microplastic emissions as an alternative to synthetic fibers made of plastics by applying the contingent valuation method. A nationwide web-based survey was conducted for 1,052 respondents proportional to region, age, and gender during February 2021. More than 75% of the sample expressed intentions to purchase microplastic emission-reducing clothing instead of synthetic fiber clothing, and more than 80% of them have stated their willingness to pay for additional prices. A variation of Heckman's sample selection model was adopted to estimate factors affecting respondents' intentions to pay for additional prices, in which the probit model of intentions to purchase the clothing with alternative materials was used as a sample selection equation. While respondents were sensitive to the amounts of price increases suggested in the CV scenario, they expressed high acceptance and preferences for eco-friendly materials regardless of the microplastic emission-reducing levels. Consumers in the circular economy were willing to pay for the range of 41,000 to 51,000 won for a pair of clothing made with microplastic emission-reducing materials. In addition, as the microplastic emission-reducing rate has increased from 50% to 80%, the willingness to pay estimates were also significantly increased, ranging from 41,000~50,500 to 42,000~51,700 won.

The purpose of this research was to develop a typology of fair-trade apparel consumers and present a clear overview of the influence of product knowledge on consumer behaviors. A two-step cluster analysis was used to classify respondents into sub-groups based on their level of self-perceived knowledge and purchase experience. In addition, ANOVA was used to test the predictive validity of the cluster solution. Income was the only demographic variable that significantly differed across groups. The more familiar and more experienced group had higher income than the other groups. Psychographic data showed that attitudes and moral norms varied across groups. The more familiar and more experienced group had more positive attitudes and higher level of moral norms than the less familiar and less experienced group. In terms of behavioristic data, groups differed significantly in purchase intentions and willingness to pay more for fair-trade apparel. That is, the more familiar and more experienced group was willing to pay more and had higher purchase intentions than the less familiar and less experienced group. Overall, the level of product knowledge and purchase experience were considerably low. This study thus confirmed the need to increase consumers' familiarity related to fair-trade apparel products.

Local food reflects the identity and image of a specific region. It is also a core element for determining tourists' experience of a region. The purpose of the present study was to develop a Jeju food tour package using local foods and estimate the economic value of the suggested tour package using Contingent Valuation Method (CVM). Five food tour packages were developed by researchers. In order to modify and measure the value of each package, an expert panel survey was conducted, and 'package 5' was selected as a food tour scenario for the tourist survey. A survey was conducted on 295 domestic tourists who visited Jeju within the past 10 years in order to evaluate the economic value and feasibility of the Jeju food tour package. A total fo 72.9% of respondents answered that they were willing to pay for the Jeju local food tour, and the willingness to pay (WTP) range was between ￦45,000 and ￦105,000. The primary factors correlated with WTP was food expenses, followed by leisure experience expenses, interest in local foods, education level, visit frequency and age. The WTP of the Jeju local food tour was calculated with the significantly affected factors using stepwise regression model. The result of the present study reveal that tourists' WTP increased with higher food expenses, education level, and age group. The average value of food expenses, education level, and age were substituted into the formula derived from the regression analysis, yielding 58,385.752 KRW as the WTP. The expected economic value created by exploiting the Jeju local food tour was shown to be 700 billion KRW per year, calculated by multiplying WTP of the food tour packages by the number of tourists. This study examined the feasibility and plan of the food tour package to increase the economic value of Jeju local food. In the case of the culinary tour program based on Jeju local food launching, the estimated economic effect was great. Therefore, in-depth research to merchandise the Jeju local food tour program is needed.

The Korea Institute of Civil Engineering and Building Technology provides the documents and information on the construction technology through the Construction Technology Digital Library System to enhance the technological competitiveness of the construction engineers. The purpose of this study is to measure the monetary value of information service quality in order to improve the documents and information service quality provided by this system. For this purpose, a questionnaire model was designed to apply the DBDC- CVM. We surveyed the members of 300 this systems for the amount of information that they are willing to pay to maximize the quality of information service. The correlation between the dependent variable and the explanatory variables was analyzed with the basic statistics of the survey results. The independent variables affecting the dependent variable are statistically significant. The logit model is used to estimate the monetary value of individual respondents who are willing to pay for information service quality. In previous research, we measured the use value of information service. On the other hand, this study shows that the measurement of value based on information service quality is different from previous research.

The purpose of this study is to estimate the utility value of boat fishing experience marine tourism activity in Jeju Island's Chagwido. The utility value is estimated by single bounded and double-bounded dichotomous choice contingent valuation method. The contingent valuation method is used to estimate economic values for all kinds of coastal ecosystem services. The method involves directly asking people, in a survey, how much they would be willing to pay for specific environmental services. So, the method has great flexibility, allowing valuation of a wider variety of non-market goods and services than is possible with any other non-market valuation technique. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island's Chagwido. The results show that the average willingness to pay amount(WTP) is estimated to be about 17,000 Korea won by single bounded and double-bounded dichotomous choice contingent valuation method. This indicates that the utility value of boat fishing experience marine tourism activity is estimated to be about 17,000 Korea won in Jeju Island's Chagwido.

Objectives: Recent movements in urban planning propose a promotion of health condition as one of its emerging topics as growing body of evidence suggests that individual health is correlated with the built environment. The concept of healthy city was introduced in Korea and many local governments were tried to implement relevant policies. However, empirical studies were insufficient for understanding the relationship between health and the built environment. Most studies and policies were viewed and implemented from public health perspective. The purpose of this study is to estimate a value of healthy city as an activity-friendly environment. Methods: The 195-respondent survey data in Seoul Metropolitan Area was used for estimating the perception of healthy cities. Results: Survey results reported that more than 90% of respondents did walking and/or biking regularly. Moreover, they were willing to pay won3,695 per month for creating healthy cities. Conclusions: This study confirmed that the consideration of built environmental factor was necessary in policies of healthy city. This can offer insights into how to manage and develop the policies of healthy city to help promote individual health conditions.

In recent days, most of the lagoons in Korea have been lost on account of indiscreet development and pollution. Thus, this study measures the conservation value of the Songji lagoon, a representative lagoon in Korea by using the contingent valuation (CV) method and specifies the non-use value of Songji lagoon. The survey was carefully desigrled and implemented to meet a number of recommendation rules suggested in the literature. The overall results show that the respondents well accepted the contingent market and would be willing to pay a significant amount for the proposed program to conserve Songii lagoon. Total Conservation value of Songji lagoon amounted to approximately 21.2 billion Korean won per year. Moreover, the non-use value of Songji lagoon amounted 15.7 billion Korean won per yew. The results of measuring the conservation value provide decision-makers with data indispensable to devising a conservation and management policy.

The development of information technology provides us with more useful information but it arose to protect such information from inappropriate users. In the course of analyzing and managing the risks associated with information, it should be needed to accurately measure the value of information. We try to consider the contingent valuation method for this purpose. The contingent valuation method which is used to assess the value of public goods or nonmarket goods makes an statistical estimation for the willingness-to-pay. We show with an example how we can estimate the value of information by calculating the amount we are willing to pay the value of information that exists on the information system. Calculation is carried out by using R.

In implementing transportation projects, benefits have been estimated using conventional benefit components. However, these components have a lot of assumptions and limitations for benefit estimations and thus it seems to be difficult to obtain values of parameters as well as to overlook benefits of non-market goods in calculation process. In other words, current benefit estimations are considered that can be solely measured by directly depending on traffic volumes. Existing economic analysis do not reflect the full benefits, including direct and indirect of the project implementations. To illustrate this fact, bicycle road construction can result in various functional benefits, including improved quality of life, balanced regional development, and good scenery composition. These benefits can not be explained with conventional economic analysis. The objective of this research is to estimate valuation of bicycle road construction using Contingent Valuation Method (CVM). CVM can evaluate user's direct willingness-to-pay as well as maximize bicycle utilization with balanced regional development. This research used the coastline bicycle road construction project for example. The proposed method can be well calculated or estimated benefits for non-market goods of bicycle road constructions using CVM.

The paper is to estimate the economic value of ecotourism in Anmyeondo tidal wetlands using a double-bounded dichotomous choice (DBDC) model of the Contingent Valuation Method (CVM). For the reliability and the validity of CVM a survey was conducted for 511 visitors by personal interview method in Anmyeondo during August 2000, and respondents were asked for maximum Willingness-To-Pay (WTP) to buy a ticket fer the tidal flat's ecotourism. Overall, respondents answered that they would be willing to pay 55,879 won for a ticket under the study. All equations and results estimated are statistically significant at the 1% or 5% level. For the aggregation of WTP estimates, the sample values are extended to the total annual number of visitors in Anmyeondo area during 1998. A conservative estimate, which considers the calibration factor (0.5) recommended by NOAA (1994) and a positive response rate (83.17%), is 73 billion won.
