Social value is the difference between monetized social impacts and related economic investments. Stimulating positive social value is a leading concern and focus for sport event stakeholders. However, insights on this socioeconomic phenomenon have concentrated on social or economic mechanisms, not both, and are siloed to host city residents, largely overlooking nonhost city residents central to events. Thus, we integrated social and economic mechanisms to examine host city and nonhost city residents' mega sport event social value. Data from 1,880 Canadians revealed varying social values (Vancouver and Provincial = negative; Venue-City = neutral; National = positive). Applying a reverse contingent valuation method, findings confirmed the need to integrate (monetized) social and economic mechanisms to calculate social value. Testing an augmented social exchange theory model, findings highlight residents' perceptual ambivalence to social impacts and the importance of income to estimate social value. Stakeholders should effectively leverage events for social impacts and reconsider event public funding allocation policies. [ABSTRACT FROM AUTHOR]

On the path to carbon neutrality by 2050, the expansion and improvement of high-voltage power transmission lines (HV-PTL) is a critical and unavoidable energy issue that may become a potential source of public conflict. However, the discussion on this issue in South Korea has been insufficient. In this study, we analyzed public attitudes toward HV-PTLs and classified people into subgroups based on their common characteristics using latent class models. In addition, we used the contingent valuation method to estimate the public's willingness to pay (WTP) for the conversion of overhead lines to underground cables, focusing on the differences among the identified subgroups. According to the empirical analysis, people in South Korea can be divided into four classes based on their perceived need for resident participation in the decision-making process, perceived health risk, and perceived property loss risk. According to the WTP analysis using the spike model, the estimated mean and median WTP values were KRW 4184 (USD 3.8) and KRW 2632 (USD 2.4) per household per month, respectively. In addition, we found a significant difference in WTP by class. Those who perceived HV-PTL as risky were less willing to pay for undergrounding projects compared with those whose perceived risk was relatively low. This study contributes to the understanding of academics and policymakers on the relationship between public attitudes toward HV-PTL and overhead to underground conversion. [ABSTRACT FROM AUTHOR]

We estimate the willingness to pay to escape different bundles of social restrictions imposed by the authorities in Iceland during COVID-19 using contingent valuation methods. Average willingness to pay to escape a bundle of social restrictions for 1 month is USD 139, amounting to approximately 2% of monthly GDP per capita in Iceland. We also find a net preference for substantial entry restrictions at the country's border. [ABSTRACT FROM AUTHOR]

Background: Transfusion-dependent β-thalassemia (TDT) is one of the global public health concerns highlighted by the World Health Organization. Patients with TDT require regular blood transfusion to survive. However, the availability of blood resources is extremely limited. The purpose of this study was to investigate transfusion burden and willingness to pay (WTP) for temporary remission of anemia status among patients with TDT and to explore the associated factors. Methods: Adult patients with TDT were recruited through cluster sampling across several high-incidence provinces in China. Consenting patients completed online questionnaires on demographic information, transfusion burden and WTP with real-time WeChat communication assistance from researchers. The guiding techniques of double-bounded dichotomous choices and open-ended questions in the contingent valuation method (CVM) were used to obtain participants' WTP for 1 unit of leukocyte-depleted red blood cells. WTP calculations were performed using maximum likelihood estimation, with further insights gained through subgroup analysis based on gender, family monthly income level and convenience of blood transfusion. Results: The analysis included 149 TDT patients from five high-incidence provinces, with an average monthly income of $198.5. Patients received an average of 3.7 units per transfusion, 15.4 times annually, with an average WTP of $70.4 per unit (95% CI [62.0, 78.9]). Estimated WTP for temporary anemia alleviation per transfusion totaled $260.6, exceeding monthly income by 1.32 times. Higher WTP was observed among males, higher-income households, and those with at least junior education. Lower WTP was noted among patients with lower transfusion volumes and those needing to travel for transfusion or during hospitalization for blood transfusion. Conclusion: High WTP indicated a strong desire for temporary anemia relief. Most TDT patients faced significant economic and transfusion burden. The evident gap in meeting clinical needed underscores the urgent demand for innovative treatments to reduce transfusion dependency, potentially transforming TDT care and improving socioeconomic well-being and clinical outcomes. These findings supported evidence-based decision-making for TDT pharmacoeconomics and efficient healthcare resource allocation in China. Key points: In China, patients generally had low economic levels and faced high transfusion burden and severe challenges in obtaining transfusion. They received an average of 1.4 blood transfusions per month. In addition, 25.5% of patients did not receive regular transfusion, and 91.9% experienced delayed transfusions. Chinese transfusion-dependent β-thalassemia (TDT) patients, aiming to temporarily alleviate anemic conditions, were willing to pay up to RMB 513.5 (USD 70.4) for 1 unit of leukocyte-depleted red blood cells. This finding may provide valuable insights for future health economic studies focused on TDT. Male gender, higher household income, and education beyond junior high school were correlated with higher WTP. Additionally, patients with lower single-transfusion volumes and more convenience of blood transfusion exhibited higher WTP. [ABSTRACT FROM AUTHOR]

This research used open-ended, single-bonded, and double-bounded dichotomous choice questions to determine consumer willingness to pay for chicken free of antibiotics in Yazd. 525 questionnaires were filled out as part of an in-store survey in June 2018 to gather the necessary data. This study's highlights include validating the fundamental hypotheses of the Tobit model for open-ended questions as well as using the best bid vector and a cheap talk script to lessen the bias in the contingent valuation method's findings for dichotomous questions. The findings demonstrated that, based on the open-ended question, the projected and actual proportion of people who would be prepared to pay extra for the characteristic of being antibiotic-free is more than 21%. Besides, the average willingness to surplus payment per kilogram of antibiotic-free chicken meat compared to conventional chicken meat for double-bounded, and single-bonded methods is 20% and 18%, respectively. According to the findings of several models' estimates, socioeconomic factors including household size, income, and socioeconomic characteristics like the age and education of the head of the household all significantly influenced consumers' willingness to pay for chicken meat free of antibiotics. The willingness to purchase chicken meat devoid of antibiotics reveals that people are concerned about the security and welfare of the chicken meat. This could be an opportunity to develop manufacturing and processing industries to provide products with desired characteristics. [ABSTRACT FROM AUTHOR]

This study aimed to analyze the carrying capacity of Curug Cimarinjung and Puncak Darma using the Douglass method and the willingness to pay for conservation fees using the Contingent Valuation Method Respondents to the research were 150 tourists and several tourism managers. Curug Cimarinjung can accommodate as many as 184 people day-1, and the Puncak Darma as many as 118 people day-1. Tourists who were willing to pay for conservation fees comprised 78% of the total respondents with a one-time payment mechanism through an entrance ticket. In total of 39.39% of respondents were not willing to pay as they believed that it was the responsibility of the government. The conservation costs were IDR 10,000 for Curug Cimarinjung and IDR 5,000 for Puncak Darma. The difference in conservation costs was because the attractiveness of the attractions in the two tourist spots varied, thus affecting the number of tourists and the nominal amount that tourists were willing to pay. If the tariff was adjusted according to the average Willingness to Pay, an entry fee at Cimarinjung Waterfall would have been charged, which was initially IDR 5,000 per person, would have been IDR 15,000 per person, while at Puncak Darma it would have been IDR 3,000 per person to IDR 8,000 per person. Determining ticket prices that had been adjusted to the average Willingness to Pay could control the number of visits so that they did not exceed capacity and did not disturb biodiversity conservation. In such conditions, tourists could carry out tourist activities comfortably and safely. [ABSTRACT FROM AUTHOR]

In the residential housing sector, energy conservation issues may arise in the relationship between landlords and renters (a.k.a. tenants) due to principal-agent and information problems. An example is the split incentive, where one party makes the energy efficiency decisions while the other pays the energy bill. Herein, we investigate whether the landlord and renter split incentive problem may be more likely and more challenging for college student renters than those who are not college students. This may occur from landlords perceiving that college renters lack sufficient demand for energy efficient improvements. There is a lack of studies regarding the possibility that college renters may face greater exposure to the split incentive problem. We surveyed landlords to better understand their prior energy efficiency investment decisions and used a contingent valuation question to further investigate their choices for a hypothetical return on investment scenario. The landlords had various mixes of college students and non-students in their properties. Landlords renting one single-family property exclusively to college students had, on average, completed fewer major upgrades to their rental properties and were less likely to invest in a hypothetical insulation upgrade.

Afforestation (AF) in farmland has been widely used as an alternative and sustainable land-use practice to address socioeconomic and environmental challenges. The aim of this study is to estimate farmers' willingness to accept (WTA) compensation and land, both of which are equally significant for policymakers to ensure the effective implementation of AF and achieve desired outcomes. This topic has not been sufficiently explored in previous research. This study focused on areas characterized by insecure farming conditions, backward economies, and fragile landscapes, where farmers are generally unfamiliar with AF or compensation for ecosystem services under payment for ecosystem services programs. It assessed their attitudes towards the WTA AF, compensation, and land as an alternative practice, which remains under-researched. This is crucial for designing effective AF programs in the future to improve livelihood and enhance the quantity and quality of the environment. This study used the contingent valuation method to estimate the minimum WTA compensation and maximum land for the forgone loss and alternative land-use practices. A questionnaire survey was conducted in Hupsekot municipality, Nepal, with 232 farmer households. The ordinal logistic regression model was used to analyze influencing factors of WTA compensation and land. The result showed that farmers' average WTA compensation was NPR 1268.67 (USD 9.76)/Kattha/year, with 2.64 Kattha land available for AF. The factors, including socioeconomic characters and attitudes toward the environmental situation and forests, significantly influenced WTA values and provided potential target factors to achieve maximum AF land within a lower budget.

The rise of sun and beach tourism has led to concerns about the environmental impact of sunscreens on marine ecosystems. Although the contaminants included in sunscreens are being studied from various perspectives, there are still gaps in the understanding of beachgoers' habits and sunscreen use, and their awareness of the problems these products can cause. But do we even know how much sunscreen ends up in the ocean when beachgoers apply it? To estimate the amount of sunscreen entering coastal waters during a summer season, a survey (n = 429) was conducted at two urban beaches in southern Spain (La Caleta and La Bajadilla). It was estimated that 76.3 to 109.3 mL of sunscreen per beachgoer enters the water during the season. For this estimation, it was crucial that we the analyze beachgoers' behavior statistically. Additionally, our study calculated their willingness to pay (WTP) for eco-labeled sunscreen alternatives. The results showed significant differences between the two sites, with La Bajadilla reporting higher sunscreen usage (11.9 mL vs. 7.9 mL per application) and a greater WTP for eco-labeled sunscreen (€14.2 vs. €11.5). These findings highlight the need for more field studies to better understand the input of sunscreen into coastal waters, which is closely linked to beach use and its social factors. This approach, which considers specific sunscreen input and characterizes beachgoers' habits, behaviors, and preferences for alternatives, provides valuable insights for decision-makers and may guide future research on the potential impact of sunscreens on marine ecosystems using behavioral data as well as alternative approaches to solving the problem.

This study evaluates the economic benefits of meteorological information services (MISs) provided by the Central Weather Administration (CWA) in Taiwan, specifically for Taiwan's capture fishery industry. Using the contingent valuation method (CVM) and conducting in-person interviews, we collected questionnaires from capture fishery practitioners nationwide to gather their subjective evaluations of the meteorological information services provided by the CWA. Based on these evaluations, we further investigated the respondents' willingness to pay (WTP) for the CWA's meteorological information services. An empirical analysis of the bid function was conducted to identify the key factors influencing the respondents' bidding behavior. The empirical findings indicate that the primary factors affecting bids include subjective perceptions (such as forecast accuracy ratings and the ratings of the impacts on fishing production), working location, fishing vessel tonnage, and fishing methods. The median WTP for Taiwanese capture fishery practitioners is Taiwan dollar (TWD) 2111.12 per person per year. Based on the number of capture fishery practitioners in Taiwan in 2019, the total annual economic value of applying MIS in coastal and offshore fisheries is estimated to be between TWD 376 million and TWD 496 million per year.

Introduction: Agricultural heritage, consisting of farmers' livelihood activities, experiential knowledge systems, and rural landscapes, is an integrated regional system with significant historical, cultural, and biodiversity value based on the natural environment and land use. Agricultural heritage is rich in traditional wisdom on the use of natural resources and is of great value in achieving the goals of sustainable agriculture and food security. The protection of agricultural heritage provides a favorable environment for farmers to engage in agricultural production, and provides a wide variety of potential agricultural production processes, thus adopting possibilities for the transformation of sustainable food systems. Ecological compensation can be an effective method for narrowing the development gap caused by heritage conservation. It can improve farmers' livelihoods in heritage sites and stimulate the enthusiasm of farmers to protect the agricultural heritage. Methods: Taking the mountainous Juglans hopeiensis planting system in Beijing as a case study, we evaluate the amount of ecological compensation using the contingent valuation method based on statistical data and interviews with farmers by combining with their willingness to accept compensation and income gap with other farmers. In addition, we analyze the factors affecting farmers' willingness to accept compensation. Results: The results show that ecological compensation at a standard of RMB 9823.13 yuan/(hm2·a) can meet the livelihood needs of farmers in heritage sites, thus bridging the income gap between farmers in and around the heritage sites. Whether farmers accept compensation is mainly influenced by five variables: gender, education level, per capita income, household members, and the proportion of therapy walnut income in household income. Discussion: We suggest that a concrete ecological compensation mechanism should be further constructed to ensure the effective implementation of ecological compensation and the longtime existence and development of agricultural heritage. This study can not only provide a reference for calculation of the ecological compensation amount and the establishment of ecological compensation mechanism for agricultural heritage in Beijing, but it is also crucial for the development of policies to ensure long-lasting conservation of agricultural heritage and continuous enhancement of farmers' livelihoods, and to improve the adaptation of global agricultural systems.

Background and Aims: This study aims to assess individuals' willingness to pay (WTP) for a human immunodeficiency virus (HIV) vaccine in Iran, focusing on key determinants influencing vaccine acceptance. Utilizing the contingent valuation method (CVM), we aim to provide insights into the economic and socio‐cultural factors shaping WTP in Iran. Methods: We conducted face‐to‐face surveys with 468 participants in Tehran province using purposive sampling. We analyzed demographic characteristics, perspectives on HIV/AIDS, and financial considerations alongside participants' WTP. Statistical analyses, including maximum likelihood estimation, identified factors influencing WTP. Mean WTP values were calculated to quantify the economic valuation of an HIV vaccine. Results: Higher education and monthly income significantly correlated with increased WTP, while gender, age, marital status, and health insurance showed no substantial impact. The mean WTP was 12,590.83 to 12,599.63 thousand Rials in different models, both showing statistically significant WTP values. Conclusion: Higher education and income levels are key determinants of WTP for an HIV vaccine in Iran. These findings provide valuable insights for policymakers to enhance vaccine accessibility and acceptance in Iran. [ABSTRACT FROM AUTHOR]

Using primary data collected from 389 sample households in Dangla district, Amhara region of Ethiopia, this study examined smallholder farmers' willingness to pay for ZM-GrowTM foliar fertiliser. The study employed the Tobit model to estimate the determinants of the maximum willingness to pay and a seemingly unrelated bivariate probit model to estimate the mean willingness to pay for foliar fertiliser. The results of the Tobit regression model showed that the education level of the farm household, total annual income, access to credit service, access to agricultural extension service, perception about fertiliser, and cost of the existing fertiliser have a positive and significant effect on farm households' willingness to pay. On the other hand, the age of farm households, availability of labour, and initial bid price have negative and significant effect on farm households' willingness to pay for ZM-GrowTM foliar fertiliser. The mean willingness to pay for ZM-GrowTM foliar fertiliser, estimated using the seemingly unrelated bivariate probit model, was 121.16 birr/litre (2.75 USD/litre). The corresponding mean willingness to pay amount estimated from an open-ended format was 161.105 Birr/litre (3.65 USD/litre). The results suggest that foliar fertilisers could be good alternatives to the existing fertilisers and its adoption can be further facilitated through improved access to knowledge and finance/credit.

The importance of valuing environmental resources, especially in ecotourism sites, has become increasingly important over the last two decades. Ecotourism is now considered as an important source of livelihood of local stakeholders in backward regions. Therefore, the preservation of ecotourism sites through community participation seems very important to maintain continued flow of tourists. This study aimed at recognizing the importance of community participation for the preservation of ecotourism sites. For this, this study executed a survey based on non-probability sampling in two ecotourism sites (Garpanchkot and Baranti) covering 100 respondents in Purulia District, West Bengal of India. The central issue of this study was to assess the tendency of community participation for the conservation of ecotourism sites and find the optimum condition for offering participatory labour time. This study showed that the participation of young people is high, and the majority of respondents are aware of the importance in protecting ecotourism sites. Because respondents were too poor to offer money, the contingent valuation method (CVM) was used to elicit their willingness to pay (WTP) participatory labour time for the conservation of ecotourism sites. Respondents' age, income, education level, caste, and their perceived environmental quality had significant relationship with their WTP participatory labour time by applying the ordinary least square (OLS) model. It was found that the mean WTP participatory labour time of each respondent in a month is approximately 3.64 h. The significance of this study is that community participation can improve the sense of belonging, trust, and credibility of ecotourism sites, making them more appreciative of the value and protection of these sites.

Cultural economics has largely looked toward environmental economics and used non-market valuation techniques such as contingent valuation to estimate the total economic value of cultural goods. These methods are well suited to the valuation of cultural heritage goods, where the benefits are mostly related to the level of supply and mainly take the form of existence and bequest values. This stands in contrast to cultural institutions such as theatres, libraries, exhibitions, and concerts, where the value is produced, when the goods are consumed. For this type of cultural goods, I suggest that cultural economics rather turn to find inspiration in the economics of education. The value of schooling can be divided into private returns and social returns (human capital externalities). Likewise, the value of cultural consumption can have a private and a public component, where I suggest labeling the public component cultural capital externalities. The idea is that when private consumption of arts and culture is taking place, the individual will accumulate cultural capital. This accumulated cultural capital can impact other people (e.g., through changed behavior, future decisions or interactions) and create externalities, i.e., the cultural capital externalities. The size of the externalities is expected to increase (or decrease) with the level of consumption. Without the consumption by the users, no externalities are produced. While this is one of the most fundamental arguments for cultural policy, it has not yet been extensively studied within cultural economics. [ABSTRACT FROM AUTHOR]

This study designs a double-bounded dichotomous questionnaire, and uses the Contingent Valuation Method (CVM) to estimate residents' willingness to pay(WTP) for water pollution control along the Taihu Lake Basin. The results of the returned questionnaire show that 82.76% of the residents are willing to pay. CVM estimation results show that the average WTP of residents for water pollution control is 138.86 yuan/year. In addition, the influencing factors of WTP are explored using a Logistic regression model, and the heterogeneity of WTP among residents of different genders is analyzed. The study found that: (1) The younger the residents, the higher their WTP; (2) The higher the income, the higher the residents' WTP for water pollution control; (3) Residents with higher educational level are more willing to pay; (4) The higher the degree of residents' understanding of water pollution control policies, the higher the WTP; (5) The higher the degree of residents' recognition of pro-environmental behavior, the higher the WTP; (6) Male residents' WTP is mainly affected by cognitive factors such as their understanding of governance policies and their approval of pro-environmental behaviors, while female residents' WTP is mainly affected by personal attributes, such as age, income, and the number of household laborers. Furthermore, this study proposes targeted measures to improve residents' WTP from three aspects: the government enriches the channels for residents to participate in water pollution control, the social media enriches the popularization of water environment knowledge, and the school strengthens the education of environmental protection knowledge, considering the differences in residents' characteristics. Therefore, this study can provide a theoretical reference and decision-making basis for encouraging residents to participate in water pollution control, promote the construction of a beautiful watershed, and provide a reference for other basins.

Global warming concerns have emphasized the need for carbon neutrality. Improving the efficiency of the electricity industry is one method of reducing CO2 emissions. There is a demand response policy that trades the saved electricity through voluntary adjustment of consumption patterns. The introduction of real-time pricing (RTP) based on advanced power supply systems is a method of transitioning to a demand-oriented power system. However, as Korea's power supply system is a relatively less efficient single-rate system, it is necessary to improve the efficiency of demand management. To transition to a demand-oriented power system in Korea, consumer preference is first investigated. This study evaluates the willingness to pay (WTP) for the introduction of RTP in Korea. Based on a survey of 500 households using the contingent valuation method, the monthly average WTP was found to be 2465 Korean won per household ($2.18 per household), which is approximately 7.8% of the electricity rate. Several additional factors influencing WTP were analyzed. Further analysis indicated that it is more effective to establish infrastructure for introducing RTP in local areas with low average electricity rates. These findings are beneficial for the development of future demand response policies. [ABSTRACT FROM AUTHOR]

There is increased call to demonstrate the benefits of EU Member States' river basin management plans, whose implementation has been delayed largely due to insufficient funding. This paper applies a contingent valuation study to investigate the benefit value of improved ecological status in river basins and the discrepancy between the quality of waters as perceived by river basin residents and as monitored under the Water Framework Directive. Respondents often reported worse quality for their focal water body than the monitored status indicated, a tendency established in a GIS analysis. The likelihood of such divergence increased most with degree of perceived deterioration of surface waters. Observed deterioration in waters, official status of one's focal water body and divergence between two quality measures had implications for welfare estimates. Describing water quality according to ecological criteria and as uniformly as possible would facilitate the use of valuation results in future benefit transfers. [ABSTRACT FROM AUTHOR]

This study examined the factors influencing visitors' willingness to pay for improved ecosystem services through the conservation of the Mudumalai Tiger Reserve (MTR) in the Nilgiris District, Tamil Nadu, India. The MTR plays a crucial role in providing and protecting various ecosystem services. However, it is vulnerable to negative externalities and drivers of ecosystem change, which affect the quality and quantity of ecosystem services, leading to the loss of valuable ecosystem services. To address this issue, it is necessary to understand the adverse effects of externalities and drivers of ecosystem change, as well as to consider people's preferences. To investigate the factors influencing visitors' willingness to pay for enhanced ecosystem services in MTR, this study used a dichotomous choice-contingent valuation method and a logit regression model. The study found that 64% of visitors expressed concern about mitigating adverse impacts and were willing to provide financial support. The results of the logit regression analysis further revealed that factors such as family size, respondent education, monthly family income, environmental awareness, and bid price significantly influenced visitors' willingness to pay. To enhance ecosystem benefits and address the challenges in tiger conservation within the reserve, our study suggests that several measures need to be implemented, including prioritizing education, awareness, the mitigation of human–wildlife conflict, and income-linked and dynamic pricing strategies.

The embedding effect represents one of the most challenging problems of the contingent valuation (CV) method. The purpose of this study is to address the issue of embedding effect in the context of museums, by estimating the size and extent of the problem. A CV study conducted in Denmark asked respondents to evaluate both the Danish museum-system (inclusive good) and the specific local museum in their municipality of residence (embedded good). Typically, an equal or very close willingness-to-pay (WTP) for the two goods would indicate the presence of an embedding effect. However, we show that this will only be the case for some respondents, while for others the similarity between the two WTP reflects an exclusive interest for the local museum. We demonstrate the existence of these two different types of respondents by using a latent class model where respondents are clustered based on answers to the CV survey. Consequently, the aggregate WTP and the bias associated with the embedding effect are estimated. Our results have implications in terms of the reliability of CV studies and its implementation in actual policy issues, demonstrating that the right questions and techniques will facilitate the separation of 'true' answers from biased ones.

When patients lack information about their medications, they are more likely to experience adverse events that may have costly health outcomes. One possible approach for improving the information that patients receive about their medications is to standardize the written information that pharmacies provide so that it is uniform and easier to read. While patients have expressed a preference for this standardization, no previous study has provided nationally representative estimates of its monetary benefits. In this paper, we estimate willingness to pay (WTP) to measure the potential benefits of standardizing the medication information leaflets that pharmacies provide to patients. We use data collected from an online, nationally representative, stated preference survey administered to non-institutionalized adults age 18 and over in the United States. Survey respondents were randomized to receive either open-ended valuation questions or referendum-style valuation questions. Responses from the open-ended questions suggest a mean WTP between approximately $3 and $13 per year depending on the treatment of outliers. Regression results suggest that those who received the referendum-style questions would be willing to pay, on average, just under $7 per year for the standardization. [ABSTRACT FROM AUTHOR]

Abstract Introduction Cataracts represent a significant public health issue and are the most prevalent vision disorder following refractive errors. They can restrict the economic, social, and psychological activities of those affected, thereby diminishing their quality of life. This study was undertaken to examine the willingness to pay for cataract surgery and the factors influencing this decision in selected medical centers in Urmia. The two-stage Heckman model was utilized to aid decision-making in financing this service. Methods This research was a descriptive-analytical study evaluating the economic aspects of health interventions, conducted from the patient’s perspective. In this cross-sectional study, a sample size of 217 patients with cataract issues was selected using Michel Carson’s table. These patients were from Imam Khomeini Hospital and Aftab Urmia Surgery Center in 2023. Data was collected using a conditional valuation approach to determine the maximum amount patients were willing to pay, as gathered through a questionnaire. The factors influencing the willingness to pay for cataract surgery were estimated using the two-stage Heckman regression model. The final effect value of each variable was calculated using Stata version 14 software. Results In this study, 81.11% of participants (176 individuals) expressed a willingness to pay for cataract surgery, with the average amount they were willing to pay being $206.3. However, out of the 217 respondents, 41 rejected the proposed amounts and were not willing to pay anything. The results of the Hemken model indicated that the income of patients and the size of their households significantly influenced their willingness to pay for cataract surgery. However, other variables investigated did not have a significant impact. Conclusion The study results revealed a significant influence of both income and household size on the likelihood of willingness to pay, as well as the extent of willingness to pay for cataract surgery. Consequently, it is crucial to formulate policies and provisions that guarantee access to cataract services, particularly for individuals from large households with low income and high costs.

The purpose of this article is to evaluate the water company in Algeria (ADE) subscribers’ Willingness To Pay (WTP) for a better service offer. This study assessed the WTP for improved drinking water in the department of Souk-Ahras (Algeria), using contingent valuation survey data of 5,342 households, with a response rate of 10.86% (greater than 10% of each municipality's total number of subscribers). Then, Probit and Tobit models were applied to analyze the determinants of WTP. The results show that the majority of respondents (62.84%) testified that they were not satisfied with the quality of the service provided in terms of quantity and quality of the water distributed. This research revealed that the WTP for an improved water supply service was approximately 16.18 Algerian dinar (DZD)/m3 (approximately 0.11 US$/m3) instead of the current tariff (6.3 DZD/m3–0.04 US$ /m3). With this new water tariff, the average water charge for a household is around 1.37% of the average monthly income. HIGHLIGHTS The households reported an average WTP of 0.11 US$/m3.; The determinants of WTP were analyzed using the Probit and Tobit models.; 62.84% of respondents stated that they were dissatisfied with the service in terms of the quantity and quality of the water distributed.; The application of the new tariff increased the water bill from 220%.; If the ADE applies the new tariff, the annual revenue will be 1,691,056.62 US$.;

Abstract Public support is critical for the incorporation of farm animal welfare (FAW) standards into national food policies. Multiple pathways, e.g., market-based policies, political mandates, and donations to animal charities, exist for the public to influence these standards. The challenge often remains that citizens may express significantly different regulatory preferences from consumers thereby disproportionally overburdening the latter. For food, this consumer–citizen role is directly linked to dietary choice. Although a large body of research has examined the determinants of dietary choice on the one hand, and FAW policy preferences, on the other, no attempt has been made to address these issues side by side. This study explores the preferences for FAW regulatory mechanisms and strategic behavior among dietary groups. Preferences for private labeling, political mandates, and donations to charities in support of and against conventional agriculture are examined. Data are from an online survey of 1020 residents conducted in the US. The results show a proclivity among segments of the public who do not consume livestock products for political mandates and the tendency to behave strategically. Regulatory preferences are embedded within distinct human value orientations. Urban—non-urban, generational and gender divides in regulatory preferences are also identified. These insights are relevant for the ongoing development of FAW standards given the portfolio of mechanisms at the disposal of stakeholders.

Introduction: Cataracts represent a significant public health issue and are the most prevalent vision disorder following refractive errors.

The results of the Hemken model indicated that the income of patients and the size of their households significantly influenced their willingness to pay for cataract surgery. However, other variables investigated did not have a significant impact. Conclusion: The study results revealed a significant influence of both income and household size on the likelihood of willingness to pay, as well as the extent of willingness to pay for cataract surgery. Consequently, it is crucial to formulate policies and provisions that guarantee access to cataract services, particularly for individuals from large households with low income and high costs.

The value of statistical life (VSL) reflects the trade-off between money and the risk of death. It is a key indicator for conducting regulatory impact assessments. The main purpose of this study was to estimate the VSL in the field of food safety. At the same time, it investigates respondents' willingness to pay (WTP) for reducing the risk of death from foodborne illnesses and explores the impact of factors such as the average household monthly income, health status, and education level on WTP. We conducted a survey using an open-ended contingent valuation method among 1307 respondents aged 18 and above to determine their WTP. Based on the WTP survey results, we calculated the VSL in the food safety sector. We used binary logit and Tobit models to analyze the influencing factors. The results of the study show that the median WTP for reducing the risk of foodborne illness is CNY 100 (USD 16), and the estimated VSL is approximately CNY 9.09 million (USD 141 million). Indicators such as the average household monthly income, health status, and education level are important factors affecting WTP. This study will help practitioners, researchers, and policymakers understand the current population's attitudes towards food safety regulations and determine the priorities for regulatory implementation. Future research can explore the effects of different elicitation methods, cultural differences, and regional variations on WTP and VSL. [ABSTRACT FROM AUTHOR]

Since the early 2000s there has been an increase in detection and awareness of per- or polyfluoroalkyl (PFAS) substances chemicals in groundwater and drinking water in the United States. In stark contrast to other known harmful chemical pollutants, little is known yet about the specific epidemiological and toxicological effects of prolonged intake and consumption of PFAS chemicals in environmentally occurring levels. New Hampshire has encountered two high-profile episodes of PFAS contamination with hotspots in Merrimack, NH, because of factory pollution and Pease International Tradeport in Portsmouth, NH, because of military activity. These instances have brought increased attention to the issue from both the state legislature and residents. The purpose of this study is to gather information on how New Hampshire residents value the removal of PFAS chemicals from their public drinking water systems to reduce the risk of possible negative health outcomes that come with PFAS intake. Using data from an online survey of New Hampshire (NH) residents and employing the contingent valuation method, we used several regression techniques to determine that NH residents are willing to pay an additional $13.07 to their existing water bill to remove the risk of negative health outcomes stemming from PFAS consumption. The most important confounding factor influencing higher willingness-to-pay values was the presence of moderate or major existing health concerns about drinking tap water. [ABSTRACT FROM AUTHOR]

Understanding visitors' willingness to pay (WTP) for natural ecosystems can assist policymakers in managing the environmental assets that form the foundation of nature-based tourism. To earn the highest economic return from limited budgetary resources, tourist-dependent destinations must identify sustainable sources of conservation funding and prioritize spending across ecosystems and initiatives. The purpose of this study is to assess the potential for visitor donations to serve as a source of conservation funding and investigate preferences and willingness to pay for multiple ecosystems concurrently, using data from a stated preference survey administered in Grenada, a small island state in the southern Caribbean that relies on nature-based tourism. Results from a discrete choice experiment and a contingent valuation exercise reveal a reluctance to donate to conservation initiatives by more than half of respondents. Visitors place the highest value on improvements to coral reefs, followed by rainforests, mangroves, and beaches. Average willingness to donate to a conservation trust fund ranged from US $8.00 to US $15.00, and from US $17.00 to US $52.00 for conservation plans targeting improvements to specific ecosystems. Few factors are found to be associated with willingness to pay. Scale heterogeneity may be a more significant source of variation than preference heterogeneity. [ABSTRACT FROM AUTHOR]

Understanding and estimating the economic value that society places on agricultural soil quality protection and improvement can guide the development of policies aimed at mitigating pollution, promoting conservation, or incentivizing sustainable land management practices. We estimate the general public's willingness to pay (WTP) for agricultural soil quality protection and improvement in Spain (n = 1000) and the UK (n = 984) using data from a cross-sectional survey via Qualtrics panels in March–April 2021. We use a double-bound dichotomous choice contingent valuation approach to elicit the individuals' WTP. We investigate the effect of uncertainty on the success of policies aiming at achieving soil protection. In addition, to understand the heterogeneity in individuals' WTP for agricultural soil quality protection and improvement, we model individuals' WTP through individuals' awareness and attitudes toward agricultural soil quality protection and the environment; trust in institutions; risk and time preferences; pro-social behavior; and socio-demographics in Spain and the UK. We found that there is significant public support for agricultural soil quality protection and improvement in Spain and the UK. We also found that the support does not vary significantly under uncertainty of success of policies aiming at achieving soil protection. However, the individual's reasons for supporting agricultural soil quality protection and improvement are found to depend on the level of uncertainty and country. Hence, promoting public support for soil protection needs to be tailored according to the level of the general public's perceived uncertainty and geographic location. [ABSTRACT FROM AUTHOR]

Contingent valuation surveys generally elicit stated preferences by asking how much a respondent would be willing to pay for an environmental improvement. By drawing on linguistic theory, we propose that the modal phrasing of this question establishes a particular type of commitment towards a hypothetical payment, namely a subjective want or desire. Based on the idea that beyond subjective desires, considerations about what is morally adequate may guide expressed values and that elicitation of these can be linguistically facilitated, we employ an experimental framework to investigate the effects of different modals (willing, should and appropriate) in the elicitation question on stated preferences. We find that elicited amounts with appropriate are higher than those elicited with willing and should for environmental improvements more associated with use values, while differences are non-significant for environmental improvements more associated with non-use values. We discuss the implications of our findings for stated preference studies, as well as the potential broader theoretical implications that our study entails regarding linguistic representations of the moral entrenchment of environmental values.

Local emergency managers play a significant role in mitigating, preparing for, responding to, and recovering from disasters. However, the fiscal stress that local governments often face limits their ability to hire and retain emergency managers within their jurisdiction. In this article, we aim to investigate public demand and support for hiring full-time, paid local emergency managers, a critical step to enhancing local emergency management capacity. We utilize the Contingent Valuation Method (CVM) to examine the average amount of additional local taxes that citizens are willing to pay in order to have a full-time, paid emergency management professional in their local government. Our analysis indicates that the average willingness to pay (WTP) for hiring a full-time, paid emergency manager ranges from $24 to $28 per household in extra local tax dollars. The estimated cost-benefit ratio suggests that hiring full-time paid emergency managers could be a cost-effective option for enhancing local emergency management capacity. Furthermore, our findings show that public willingness to pay for this policy change is correlated with social trust, political beliefs, and income level. [ABSTRACT FROM AUTHOR]

We use a nested constant elasticity of substitution utility function to introduce a private environmental substitute in a theoretical model. We find that a buyer's income elasticity of willingness to pay (WTP) increases with the price of the substitute and decreases with income. A higher price and a lower income also discourage purchase of the substitute, reducing the proportion of buyers in population. We must therefore consider both dimensions when discussing societal mean WTP. An empirical check based on a contingent valuation survey confirms our theoretical findings. Projected income-WTP curves reveal inequality further reduces the mean WTP in the presence of private environmental substitutes. [ABSTRACT FROM AUTHOR]

The structure and types of social networks created by entrepreneurs are important factors influencing business performance. This study examined how social networks influence the performance of agribusinesses owned by young women, as well as the moderating effects of business environments on these relationships. Data were collected from a sample of 365 young women agri-food processing business owners in Benin. Moderated multiple regression methods were used to test the suggested hypotheses including the interaction effects of business environment. Network size, network centrality, competitive network, and supportive network each has a positive effect on the performance of agribusinesses owned by young women. Network size and network centrality are more beneficial when barriers in business environment are low than when they are high. The two-way interactions of network types (competitive and supportive) and business environment on business performance were not significant. Drawing on social capital theory, this study provides a contingent perspective of network size and network centrality in a developing country context. The findings of the study provide useful guidelines for young women agribusiness owners on which social ties to develop. Rules and regulations on taxes need to be streamlined and made more flexible.

Taiwan's awareness of environmental conservation and biodiversity has been increasing in recent years. As frog plays a vital role in the environment and recreational activities in Taiwan, this study aimed to quantify the willingness‐to‐pay (WTP) of the public for conserving the selected endangered frog species. Respondents were asked using a semistructured questionnaire with auxiliary audio and video files. After deleting incomplete responses following regular data handling, 585 valid responses were used in the estimation. Using the contingent valuation method and single‐bounded dichotomous choice model, the results showed that people are willing to pay an amount of 32.01 USD (922.85 New Taiwan Dollars) per person annually. Factors affecting the public's WTP include price, age, support for establishing conservation areas, payment through donations, number of trips in ecotourism, and the place of residency in Taiwan. The result of this study can be used as a benchmark for the government for the implementation of the conservation and rehabilitation of the habitat of the endangered frog species in the future. Recommendations for Resource Managers: Involvement of people in recreation like traveling, their location of residency, and their age are critical factors in the government's policy formulation.The government should promote endangered frog species conservation in the Northern part of Taiwan, towns near the conservation areas, and younger and middle‐aged populations for the immediate implementation of rehabilitation.An ecological compensation scheme shall be implemented to mitigate the impact of development on ecosystems and provide aid to those residing near conservation areas.The research focused only on Taiwan's three most representative endangered frog species. Future research direction can also focus on the ecology and quantity of the remaining endangered species subject to the study on willingness‐to‐pay the conservation value. [ABSTRACT FROM AUTHOR]

The study aims to evaluate the demand for forest bathing in northern Italy's regions, underlining the willingness to pay and the potential tourists' habits and flows on attending alpine contexts. Several studies have analyzed the psychophysical benefits of forest bathing, and there is a growing interest in assessing its economic value for tourism purposes. The sample's answers have been analyzed employing a stratified sampling methodology considering three different macro areas (northwest regions, northeast regions, and the Friuli Venezia Giulia region). After analyzing the sample's attitudes, the research approached the estimation section by calculating the flow as the number of potential forest bathing hikes per year and the willingness to pay through the contingent valuation method. The main results indicate that forest bathing activity in northern Italy has a considerable monetary value, and it is generally compared with positive feelings, particularly concerning well-being and fascination factors.

Background: Foot and mouth disease is a contagious, transboundary, and economically devastating viral disease of cloven-hoofed animals. The disease can cause many consequences, including decreased productivity, limited market access, and elimination of flocks or herds. This study aimed to assess farmers' willingness to pay (WTP) for foot and mouth disease (FMD) vaccines and identify factors influencing their WTP. A cross-sectional questionnaire survey was conducted on 396 randomly selected livestock-owning farmers from three districts in the central Oromia region (Ambo, Dendi, and Holeta districts. The study utilized the contingent valuation method, specifically employing dichotomous choice bids with double bounds, to evaluate the willingness to pay (WTP) for the FMD vaccine. Mean WTP was assessed using interval regression, and influential factors were identified. Results: The study revealed that the farmer's mean willingness to pay for a hypothetical foot and mouth disease vaccine was 37.5 Ethiopian Birr (ETB) [95% confidence interval [CI]: 34.5 40.58] in all data, while it was 23.84 (95% CI: 21.47–26.28) in the mixed farming system and 64.87 Ethiopian Birr (95% CI: 58.68 71.15) in the market-oriented farming system. We identified main livelihood, management system, sales income, breed, keeping animals for profit, and foot and mouth disease impact perception score as significant variables (p ≤ 0.05) determining the farmers' WTP for the FMD vaccine. Conclusion: Farmers demonstrated a high computed willingness to pay, which can be considered an advantage in the foot and mouth disease vaccination program in central Oromia. Therefore, it is necessary to ensure sufficient vaccine supply services to meet the high demand revealed. [ABSTRACT FROM AUTHOR]

Background: Fibromyalgia is a chronic rheumatic disease of unknown aetiology, highly disabling and mainly affecting women. The aim of our work is to estimate, on a national scale, the economic impact of this disease on the employment of patients and non-professional (informal) care dimension. Methods: Survey on Disabilities, Autonomy and Dependency carried out in Spain in 2020/21 was used to obtain information on disabled individuals with AD and their informal caregivers. Six estimation scenarios were defined as base case, depending on whether the maximum daily informal caregiving time was censored or not, and on the approach chosen for the valuation of informal caregiving time (contingent valuation and replacement time). Another six conservative scenarios were developed using the minimum wage for the estimation of labour losses. Results: Our estimates range from 2,443.6 (willingness to pay, censored informal care time) to 7,164.8 million euros (replacement cost, uncensored informal care time) (base year 2021). Multivariate analyses identified that the degree of dependency of the person suffering from fibromyalgia is the main explanatory variable for both the probability of being employed and the time spent in informal care. Conservative scenarios estimates range from 1,807 to 6,528 million euros. Conclusions: The high economic impact revealed should help to position a health problem that is relatively unknown in society and for which there are significant research and care gaps to be filled. Key Points: We estimate at national level (Spain) the economic impact of fibromyalgia on two dimensions: labour losses of patients and the value of informal care. Our estimates range from 2,443.6 (more conservative scenario in the base case) to 7,164.8 million euros (less conservative scenario in the base case) (base year 2021). The degree of dependency of the person suffering from fibromyalgia is the main explanatory variable for both the probability of being employed and the time spent in informal care.

Optimising the interaction between society and the environment is one of the fundamental directions of recreational forest management. To improve the efficiency of using ecosystem services of recreational and health-improving forests, there is a need to develop new approaches and tools for management decision-making, a key component of which is the assessment of these beneficial goods. The aim of the study is to analyse public opinion regarding the expressed and identified preferences for the characteristics of recreational forests and recreational facilities, as well as to assess the willingness to pay for preferred forest characteristics and the maintenance of recreational facilities in proper condition. The study was conducted from June to August 2022 using a direct and anonymous online survey. It was found that respondents are willing to pay an average of 1-100 UAH/year to create and maintain the preferred characteristics of the forest and 101-500 UAH/year to create and maintain recreational facilities. As for the respondents' perception of forest characteristics that affect the choice of a place to relax, preference is given to mixed forests (74.8%), in which three tree species grow (57.9%), and forests up to 20 meters high (40.2%). On the other hand, only 15.9% of respondents preferred forests taller than 20 meters. The presence of deadwood in the forest is positively perceived by 51.4% of respondents, and 10.3% do not pay attention to the presence or absence of standing dead and drying up trees in the forest. The most important needs for which respondents visit recreational forests were walks, family recreation, and observing forest landscapes. The integration of the identified perceptions and preferences regarding recreational forests and objects into innovative decision-making in the field of forestry ensures a synergy of benefits, such as increasing the attractiveness of recreational forests and forest landscapes, increasing the resilience of forests to climate change, and meeting the local demand for wood biomass.

Background and objectives: To express the role and importance of the environment and convert it to monetary values, these resources need to be valued using appropriate methods. Environmental attitude is a crucial factor in improving the description and prediction of economic models. The new environmental paradigm (NEP) is the most widely used measure of environmental attitude among the variables used in contingent valuation and willingness to pay. This study aims to estimate the recreational value and willingness to pay of tourists, considering the new environmental paradigm in the Helen Protected Forest, located in Chaharmahal and Bakhtiari province, Iran, using the contingent valuation method. Methodology: This study examines the visitor population of the Helen Protected Forest. To estimate the sample size, a pre- questionnaire was designed and completed by the tourists to determine the variance of the trait under investigation. The number of 230 samples was determined using Cochran’s formula and the information obtained from the pre-questionnaire. The contingent valuation method was applied to assess the willingness of forest tourists to pay, using the Double-bounded Dichotomous Choice questionnaire. In this method, the estimated value is determined based on the conditions of a hypothetical market. Additionally, to investigate environmental attitude, the new environmental paradigm questionnaire was used. This questionnaire contains 15 items in the form of a Likert scale. The required statistics and information were collected through random sampling on different days of the week in different seasons of 2022 with face-to-face interviews of visitors from the mentioned area. In the contingent valuation method, the logit regression model was used to investigate the effect of explanatory variables on visitors’ willingness to pay, and the parameters of this model were estimated based on the maximum likelihood method. Furthermore, using the truncated average willingness to pay, the visitors’ willingness to pay was calculated. For data analysis and estimation of the logit regression economic model, as well as for statistical analysis, the software packages Shazam and Excel were employed. Results: The results showed that 83.04% of visitors are willing to pay for recreational use of the Helen Protected Forest. The logit model indicated that the variables of the proposed amount and the number of annual visits have negative effects, while the variable of the new environmental paradigm has a positive and significant effect on people’s willingness to pay. The willingness of men and native people of Chaharmahal and Bakhtiari province to pay was significantly higher than that of women and non-native people. The variables of age, education, and income have positive and significant effects on people’s willingness to pay. The environmental statement (Ethics and Consequentialist) showed that the average willingness to pay of ethics people was higher than that of consequentialist people. The contingent valuation method estimated an average WTP of 199,793 IR Rials per household per visit and 519,461.8 IR Rials annually per family. The total annual recreation value for the Helen Protected Forest was estimated at 2,374,683,2564 IR Rials. Significantly, visitors’ environmental attitude emerged as a key factor influencing WTP. Analysis of the NEP scale revealed the highest average score (4.28) for the item “Plants and animals have as much right as humans to exist,” suggesting that visitors recognize the intrinsic value of nature. Conclusion: The use of the new environmental paradigm, along with socio-economic variables, is one of the most important factors affecting people’s willingness to pay for recreational use of Helen Protected Forest. The high percentage of willingness to pay for using the recreation service of this forest is promising from a management perspective. These results indicate the possibility of expanding recreational services, which may consequently increase economic, social, and cultural development. Additionally, the findings from this research can help adopt a suitable pricing policy to protect the natural resources of Helen Forest. [ABSTRACT FROM AUTHOR]

We study the willingness to pay (WTP) for a large set of improvements in water service related to quality, continuity, and securing access for people with no house piped water during the COVID-19 pandemic. Using primary survey data from urban Peru, and the contingent valuation method, we estimate a mean WTP of around PEN 4.3 (USD 1.05), 3.7 and 1.8, respectively, for the aforementioned sets of improvements, with the combined WTP representing a 23% increase in the households' water service monthly bill. The WTP for all sets of improvements is influenced by the expenditure in bottled water (a substitute for tap water, generally perceived as unsafe) and a proxy for household assets. The influence of the individual characteristics typically scrutinized by the literature (e.g., sex, age, and education) varies with the type of improvement examined. We find a significant heterogeneity in WTP across providers and calculate the users' contribution to a water fund that could crowd-in the public investment in water services' upgrades. We further discuss the implementation of such water fund. [ABSTRACT FROM AUTHOR]

Using an original contingent valuation, this study compares the Willingness-To-Pay (WTP) of households for three water pipes renewal programs focused respectively on water quality, reducing leaks in networks and preventing breaks. A survey was conducted in southwest France: respondents were asked to rank the different renewal programs and then state the maximum amount they would be willing to pay in order to benefit from each. Results of a Heckman model suggest that variables influencing the probability of refusing to pay for a non-economic reason and the WTP differ from one program to another, which validates this choice of model. WTP estimates are not of the same order of magnitude whatever the program, and remained relatively low when compared to the actual water bill. While asset management is often only seen as an activity calling for specialised technical knowledge, users are able to perceive the outcome of that management process. [ABSTRACT FROM AUTHOR]

Background: Willingness-to-pay (WTP) estimates are useful to policy makers only if they are generalizable beyond the moment when they are collected. To understand the "shelf life" of preference estimates, preference stability needs be tested over substantial periods of time. Methods: We tested the stability of WTP for preventative dental care (scale and polish) using a payment-card contingent valuation question administered to 909 randomized controlled trial participants at 4 time points: baseline (prerandomization) and at annual intervals for 3 years. Trial participants were regular attenders at National Health Service dental practices. Participants were randomly offered different frequencies (intensities) of scale polish (no scale and polish, 1 scale and polish per year, 2 scale and polishes per year). We also examined whether treatment allocation to these different treatment intensities influenced the stability of WTP. Interval regression methods were used to test for changes in WTP over time while controlling for changes in 2 determinants of WTP. Individual-level changes were also examined as well as the WTP function over time. Results: We found that at the aggregate level, mean WTP values were stable over time. The results were similar by trial arm. Individuals allocated to the arm with the highest scale and polish intensity (2 per year) had a slight increase in WTP toward the latter part of the trial. There was considerable variation at the individual level. The WTP function was stable over time. Conclusions: The payment-card contingent valuation method can produce stable WTP values in health over time. Future research should explore the generalizability of these results in other populations, for less familiar health care services, and using alternative elicitation methods. Highlights: Stated preferences are commonly used to value health care. Willingness-to-pay (WTP) estimates are useful only if they have a "shelf life." Little is known about the stability of WTP for health care. We test the stability of WTP for dental care over 3 y. Our results show that the contingent valuation method can produce stable WTP values.

The US Environmental Protection Agency (EPA) bases its estimate of the value of statistical life (VSL) on 17 hedonic wage studies and five contingent valuation studies conducted between 1974 and 1991. We summarize advances in the mortality risk valuation literature since these papers were published, focusing on studies conducted in the United States that value risks to adults. We review hedonic wage, other revealed preference, and stated preference studies, identifying papers that satisfy appropriate validity criteria. We conclude that the recent literature is sufficiently rich to permit a revision of EPA's baseline estimate. Importantly, VSL estimates from both the averting behavior and stated preference studies we review reflect the preferences of a wider range of demographic groups than the current VSL, and newer studies better target causes of death relevant to EPA regulations.

Ecosystem service values are divided into three categories: direct use values, indirect use values, and non-use values. In this research, the economic value of ecosystem services in canola (Brassica napus L.) fields was investigated during 2020–2021. These fields are located in Gorgan County (Sorkhankalateh region) north of Iran. We calculated the carbon sequestration by the carbon emission tax policy as shadow value of carbon, and to estimate some ecosystem services including the oxygen supply, grain yield and soil conservation, we applied the substitute cost methods, direct market method and replacement cost, respectively. Also, the value of pollination service was estimated along with the effect of pollinators on yield production, and the value of agrotourism estimated based on contingent valuation method. In this research, the logit model was used by the maximum likelihood method to investigate the influencing factors on people's willingness to pay. The required data for each of these variables were collected through field methods, questionnaires and face-to-face interviews with 117 visitors from the mentioned region. The results showed that the average total value of ecosystem services was equal to 3,685.91$ ha−1 yr−1. In this research, the value of the provisioning service was equal to 1,720.81$ ha−1. Also, the grain yield had the highest value among ecosystem services and accounted as 46.69 percent of all the ecosystem services. While, atmospheric services (oxygen production and carbon sequestration) included 1,155.12$ (31.34%), pollination 516.24$ (14.01%) and soil conservation 292.19$ (7.93%) of the total economic value. The share of agrotourism service from the total value of services was about 1.53$ (0.04%). In general, canola fields are more important in terms of provisioning services (grain yield) than regulating services such as oxygen production, carbon sequestration, soil conservation and pollination, as well as agrotourism services. Therefore, maintaining and enhancing market and non-market services in the canola fields of the study area is crucial for both the human and economic aspects. [ABSTRACT FROM AUTHOR]

This study surveyed household decision makers to determine the willingness to pay (WTP) a premium price for certified high-iron common beans and the underlying determinants in the urban areas of West Pokot County, Kenya. The data were collected from 384 respondents selected through a stratified multistage sampling technique using a pretested semi structured questionnaire. A one-and-one-half bounded contingent valuation method was utilized to assess WTP. The data were analyzed in R Software. Household decision makers were willing to pay an average price premium of Kenya Shillings 281 per kilogram. WTP was significantly influenced by age, the proportion of monthly income allocated to food items, access to nutrition information, relative trust in nutritional claims, relative trust in certification agencies and awareness of food certification. Interventions for implementing lower pricing and enhancing the trust and awareness levels of public certification agencies could be appropriate. Prices may gradually be raised once trust and familiarity with high iron common beans, have diffused among consumer segments. [ABSTRACT FROM AUTHOR]

The impacts of the COVID-19 pandemic on private grassroots music venues (GMVs) increased the difficulties in their business model, showing the vulnerability of their economic sustainability. This paper proposes ways to measure the economic value of GMVs in the city of Rio de Janeiro (RJ), Brazil, seeking to highlight the important role of such venues and of public and private support for their maintenance. To this end, an online survey was applied to 180 GMVs goers and 188 non-goers, based on the contingent valuation method. The data shows GMVs play an important role within the musical ecosystem and generate positive externalities for the city. Both goers and non-goers tend to understand this importance and identify GMVs as businesses that generate cultural and economic value for the city, showing a non-use value of the good.
