The purpose of this paper is to theoretically using two new models to analyze the effect of respondents’ uncertainty about their stated willingness to pay (WTP) on welfare estimates in the contingent valuation method (CVM) theoretically using two new models, and empirically to reveal consumers’ WTP to improve drinking water supply safety (WSS) in China.

In this paper, two alternative preference uncertainty treatment approaches are proposed to estimate consumers’ WTP theoretically and they are applied to China’s WSS improvement program from a payment card method, which depends on how consumers’ certainty level about their valuation is. Furthermore, four regression models are presented to investigate the determinants of consumers’ WTP.

Theoretically, the alternative approaches that proposed in this research can remove overestimation bias from traditional CVM method but with lower estimation efficiency. In addition, the empirical results of the uncertainty adjusted models show that the expected WTP to improve drinking WSS is from 0.55 to 0.56 Renminbi yuan/ton, which are lower than the estimates from the conventional standard CVM models. Consumers’ preferences for their concerns about WSS, attitudes toward WSS improvement programs, trusts in implement authorities and their knowledge of WSS have significant effects on the WTP for improving drinking WSS and on respondents’ uncertainty too.

Theoretically to the authors’ knowledge, it is the first attempt to compare alternative approaches to treat respondent uncertainty using numerical certainty scale combined with payment card format valuation questions in CVM. Empirically it is the first study at this large scale that investigates consumers’ WTP for improving drinking WSS incorporating with respondent uncertainty in China. In addition, to assess consumer preferences for improved drinking water safety and the sources of uncertainty, information on consumers’ attitudes toward WSS are considered at the first time.

Currently, there is a conflict in developing countries between the requirements for the self-development of forestry and the insufficient investment in the forestry sector, and the forest ticket system is an innovative forestry management method to solve this contradiction. In the research on the forest ticket system, the study of its price formation mechanism is relatively important. The key issues of the forest ticket system are how to form the forest ticket price and whether the forest ticket pricing methods are reasonable. Solving these problems is the purpose of this study.

This study will use three methods, namely the forest ecosystem service value evaluation index method, the ecosystem service value based on per unit area evaluation method and the contingent valuation method, to study the forest ticket price formation mechanism, filling the gap in the current research on forest ticket pricing methods. It will analyze how these three pricing methods specifically price the forest ticket and evaluate whether these pricing methods are reasonable. This study will then summarize and comprehensively study the forest ticket price formation mechanism and provide policy recommendations for decision-making departments.

The contingent valuation method and the forest ecosystem service value evaluation index method should be mainly used and given priority in the forest ticket pricing process. When the forest ticket is mainly issued for local residents' willingness to compensate for the forestry ecological value, the contingent valuation method should be mainly considered; when the forest ticket is mainly issued for compensating for the ecological value of local used forest land, the forest ecosystem service value evaluation index method should be mainly considered. The ecosystem service value based on per unit area evaluation method does not need to be the focus.

Compared with existing research studies, which focus more on the forest ticket system itself and the definition of forest ticket, this study mainly focuses on the forest ticket price formation mechanism, emphasizing how to form the forest ticket price and whether the forest ticket pricing methods are reasonable, which has a certain degree of innovation and research value and can partially fill the gap in related fields. At the same time, this study has certain help for the enrichment of the forest ticket system and the extension of related research studies.

The Fresh Milk Logo certifies that dairy product sold in Taiwan really is fresh milk. However, the logo represents only a moral pledge by the manufacturer. No method exists for inspecting whether products are fresh milk or reconstituted milk, and the label does not represent a commitment to the same level of quality and consumer health protection as found in organic foods. The purpose of this paper is to analyze consumer perceptions of organic certified agricultural standards (CAS) and estimates consumer willingness to pay (WTP) a premium should the Fresh Milk Logo be transformed into an organic CAS certified label.

Exploratory factor analysis is adopted to extract the main determinants of respondent perceptions and preferences. Additionally, the double-bounded dichotomous choice of the contingent valuation method (CVM) and survival function is used to measure consumer WTP a premium for organic fresh milk.

Consumer consumption preferences for buying fresh milk extracted four main factorial dimensions: Fresh Milk Logo, price/promotion, organic, and product/brand. Respondents are willing to pay US$21.95 extra per year to buy organic CAS milk and the factors affecting WTP are “Fresh Milk Logo” and “organic”.

The problems of the CVM include hypothetical and starting point for price bidding. The double-bounded dichotomous choice contingent valuation model and pre-testing can reduce the biases. The survival function is more flexible, yields more information and permits assumptions regarding parametric distributions without additional costs. The collaboration of survival function with the double-bounded method produces a reliable result that incorporates fewer statistical errors.

Consumers are willing to pay a premium for fresh milk with an organic CAS label that certifies its good quality and safety.

Marketing managers can use the study findings to develop effective marketing strategies and refine advertising campaigns to promote organic fresh milk to attract more consumers.

Organic food labels certify food safety, and are associated with the trend toward increasing awareness of environmental and health issues. Perception of organic food labels are introduced into double-bounded dichotomous choice CVM to estimate consumers’ WTP, an approach which has successfully dominated traditional methods, using Likert scale-type measurement.

The purpose of this paper is to estimate an individual’s probability of preservation of the night view of Han-River bridge tax using the contingent valuation method (CVM) and to present the effects of 4Es on experience economy theory.

The on-site survey was conducted in the 11 district Han-River parks: Gwangnaru, Jamsil, Ttukseom, Jamwon, Banpo, Yeechon, Yeouido, Mangwon, Nanji, Ganseo and Yanghwa district, including 24 bridges such as Banpo, Olympic bridge during 8-9 pm around the lighting and 9-10 pm peak time of lighting.

Truncated mean willingness-to-pay indicates that the economic value of the night view of Han-River bridge is 49,575 won (about USA $50) per household, which implies the significance of the preservation value of the night view.

This study sets a hypothetical market, and there are limitations on hypothetical bias of the dichotomous choice CVM. For the future study, a survey with a specific real payment vehicle in an attempt to reduce hypothetical bias can be a tool for the prevention of the overestimation.

Through the study, Seoul city has to invest aggressively on the night view landscape business of Han-River bridge, which can become a landmark and has lots of attraction for tourists. As this study’s core aim was to justify the economic value of the night view of the Han-River bridges, the estimated amount strongly supports the lighting business of the Han-River bridge.

The results of this research may help policy-makers of Han-River to establish practical decisions as to whether improving and preserving the Han-River’s night view lighting business are worth the value.

In the study, an attempt was made to estimate the social benefits resulting from three non-mega sporting events organized in Ergo Arena located on the border of two cities in Poland. By attributing a value to intangible social benefits, the intangible effect was determined and compared to the expenditure incurred in the construction of Ergo Arena Hall.

In order to value social intangible effects of three non-mega sporting events the Contingent Valuation Method was applied. Each time, the Contingent Valuation Method study covered the area of the two cities: Gdańsk and Sopot and was conducted on a sample of 500 people – 250 per city. The mean values of Willingness-to-Pay were used in order to obtain aggregate values of intangible benefits. Finally, the aggregate results were compared to expenditure incurred in connection with the construction of Ergo Arena Hall.

It appeared that intangible effects were eagerly valued by the residents of Gdańsk and Sopot. The aggregated value of all three sporting events was estimated at PLN 8.8 million. The obtained results question the equal share of both cities in financing but confirm that under certain circumstances, hosting non-mega sporting events may justify the use of public funds. In the case of the two cities, the reasonable reason for the employment of public means is the size of Gdańsk compared to Sopot.

The paper fulfils the research gap which arises regarding Willingness-to-Pay in estimating the intangible social effects of non-mega sporting events and considering these effects in the net effect valuation. The findings have implications for policy makers since they show to what extent it may be justified to use public means in order to host non-mega sporting events.

We all understand the everlasting harmful effects of pollution. A larger proportion of this pollution gets generated from industrial units due to use of backward technologies along with intentional or unintentional economic policies that has allowed such industries to grow over the years. Many of these industries are poor, in many cases, they do not have the ability to install abatement technologies or use emission-free green technologies for their huge cost. In many cases, they do not do so intentionally just to enjoy higher profit and due to faulty planning. But, the pollution generated from such industries makes us all suffer, especially those who live in those industrial areas. They are more exposed to the emission directly. Again, growing consensus among people about pollution has increased the consumption of eco-friendly, less-polluting products which could have a wide-ranging impact on the production techniques and can force the producers to change their production techniques, In this chapter, by applying contingent valuation method (CVM), the authors have looked to capture how far people of two very renowned industrial belts in West Bengal, Howrah and Barrackpore, are willing to contribute to the reduction of such emission level by consuming eco-friendly products and paying the emitting producers to force them to adopt pollution-free technology. The authors have applied close-ended dichotomous choice (DC) bidding technique by using logit regression and have also applied open-ended bidding process by using ordinary least square (OLS) method. In both cases, the authors have found the mean willingness to pay (WTP) is quite high which shows that people are very much willing to move towards using eco-friendly goods and technologies.

This study aims to present a new approach to measuring the economic value of special libraries, including certain time‐saving effects that the contingent valuation method application cannot exclusively prove.

A cost‐benefit analysis is used as a tool to determine whether the benefits of special libraries outweigh the cost incurred in providing the services. The benefits of such libraries are based on estimates of how much the user is willing to pay for the service, as well as the cost of time saved as a result of his contact with library services. A case study was conducted to show how special libraries could apply the proposed model to their library setting to measure the value of the library's services.

According to the case study involving the KDI School Library, the economic value of its library services measured in terms of a B/C ratio was 1.97, serving as strong justification for the library's existence.

This study is more specific and accurate than previous studies in that it enables an individual analysis for each service special libraries offer and focuses on the types of benefit derived. It is hoped that the model will help analyze the strength of each library service as well as the total economic value of the library.

The contingent valuation method (CVM) for assessing non‐use values has undergone significant criticism recently on various fronts. In this paper, the author analyses the notion that imposing reasonable bounds on the rationality of agents might undermine the basis for any method that attempts to elicit non‐use values on environmental goods from individuals, including CVM. The model of bounded rationality applied is that of Gans (1996). On the basis of that model, it is argued that in complex and unfamiliar situations one would not expect individuals to be able to express their true preferences. Following this line, the author discusses the possibilities for using experts for valuation as well as for providing information for decision making on the preservation of public resources.

The purpose of this paper is to identify a list of underlying considerations in choosing the appropriate economic valuation method for use in the conservation of historic property and to highlight the importance of non‐use values in making decisions.

A thorough literature review is conducted to provide a concise overview of the most commonly used economic valuation methods in the cultural heritage field. The stated and revealed preference methods were analyzed. Their theoretical basis, methodology and analysis procedures are described. By highlighting the strengths and limitations of these evaluation methods for use in the different context, a list of underlying factors for choosing the appropriate method for different decision‐making problems in managing historic properties were deduced.

The underlying considerations in choosing the appropriate evaluation method in historic properties include “Matching the objectives ”, “Evaluate use or non‐use values ”, “Scope of evaluation ”, “availability of data”, “Time and cost of conducting the methods”, “Methodological procedures”, “Analysis of the methods”, and “Local contexts where the techniques will be applied”.

The long‐term significance of this study is to enhance a holistic understanding of the quantitative approach to evaluate the value of historic properties. This enhanced understanding should help to inform the decision‐makings on comparing and prioritizing the management of heritage facilities when confronted with limited resources.

Considering built heritage as public goods demands a lot of planning as usually historic sites and monuments are administrated by governments. The purpose of this paper is to propose and apply contingent valuation method (CVM) for the value assessment of historic sites as public goods.

The aim of this research is to apply CVM to assess the total value as well as sub values, use and non-use values of a historic site. Ferdowsi mausoleum in Tus historic area near Mashhad city in Iran has been chosen as a case study.

The paper indicates that historic sites meet all the criteria for being considered as public goods and obtained high amount of willingness to pay proves the significance of Ferdowsi mausoleum to the people of Mashhad city and its tourists. Non-use values comprise the highest share of value and cultural identity has the highest value among non-use values.

It is recommended that CVM be applied in cost-benefit analysis of historic sites. This is useful in the process of prioritization of restoration and maintenance of historic sites and could be used by policy makers in policy crafting processes.

CVM has been used for the first time for a mausoleum and for a site in Iran and sub values have been measured for the first time for a historic site.
