Consumer WTP for Blueberry Attributes: A Hierarchical Bayesian Approach in the WTP Space AgEcon
Shi, Lijia; House, Lisa; Gao, Zhifeng.
A stated preference experiment is conducted to elicit consumer WTPs for various blueberry attributes. The mixed logit model is employed to account for consumer heterogeneity. The model is set up in the WTP space where the distributions of WTPs are directly specified. Considering the high diversity of consumer perception and the remarkable benefits from differential marketing, we apply the hierarchical Bayesian approach and the discussion is based on the individual level WTP estimates. The results show that “local produced” attribute is preferred over simply “produced in the U.S.” by most respondents. By contrast, less than 50% of the respondents are willing to pay premium for organic blueberries. In addition, hardly any relationship between demographics...

Willingness to Pay for Traceable Meat Attributes: A Meta-analysis AgEcon
Cicia, Gianni; Colantuoni, Francesca.
Several researches evaluated consumers’ Willingness To Pay (WTP) for each meat traceable attribute, generating a great deal of information in this regard, although specific to the conditions of each study. In light of this, WTP estimates for traceability characteristics differ across the literature, leading sometimes to contrasting interpretations. Seeking a full, meaningful statistical description of the findings of a collection of studies, the meta-analysis allows us to analyze consistency across studies and control for factors thought to drive variations in WTP estimates. The meta-analysis has been conducted using 23 studies that, in aggregate, report 88 valuations for WTP. Our results, aside from releasing unconditional information on the WTP for...

Consumer Willingness to Pay for Food Safety in Beijing: A Case Study of Food Additives AgEcon
Liu, Yuanyuan; Zeng, Yinchu; Yu, Xiaohua.
Constructing a theoretical framework and using a survey data of 294 customers from 25 supermarkets in Beijing, this paper studies the willingness to pay (WTP) for additive-free Mooncakes in Beijing and finds that age and income are important for WTP for “food safety” in China. Income is positively correlated with the WTP and there is an inverted-U-shaped relationship between age and WTP. This study indicates that consumers in Beijing are willing to pay 5.80 Yuan more for an additive-free Mooncake, which provides a good policy benchmark for the government regulation on food additives. Furthermore, the theoretical framework also provides a good benchmark for understanding WTP in the future study of food safety.

Eliciting public preferences for managing the public rights of way AgEcon
Morris, Joe; Colombo, Sergio; Angus, Andrew J.; Stacey, K.; Parsons, D.; Brawn, M.; Hanley, Nick.
Public Rights of Way (PROW) in England and Wales, provides a wide range of social and economic benefits to those other than owners of land. The protection and extension of PROW are an important way of encouraging people to engage in informal enjoyment of urban and rural areas, with beneficial consequences for health and welfare. In urban areas they provide networks of mobility and interaction for people at the community level, helping to reduce reliance on motorised transport. In the rural context they define access to the countryside, critically linked to recreation and tourism, as well as providing mobility networks for local residents. This study describes the use of a Choice Experiment (CE) to derive monetary estimates the social benefits of PROW in an...

Valuing a Clean River: A case study of Musi River, Hyderabad, India AgEcon
Gayathri Devi, Mekala; Samad, Madar; Davidson, Brian; Boland, Anne-Maree.
The current study uses contingent valuation technique to estimate the value of clean water in river Musi in Hyderabad, India. The main source of pollution of the river is untreated domestic and industrial wastewater from the urban area of Hyderabad. Therefore, people’s Willingness To Pay [WTP] for the treatment of their wastewater to different quality levels (Level C, B & A) is estimated using a payment card method. Four variables were considered to influence the willingness to pay - number of years the household lived in Hyderabad; individual perceived importance of controlling water pollution; household income levels and proximity to the river. The results of the logistic regression confirmed that the variables - perceived importance of the...

Risk Belief, Producer Demand, and Valuation of Improved Irrigations: Results from Field Experiments in Mt. Kilimanjaro AgEcon
Muamba, Francis; Kraybill, David S..
This paper systematically estimates the potential benefit of introducing improved irrigation schemes in Mt. Kilimanjaro to help rain dependent farmers cope with the risks of climate change. The study uses Contingent Valuation Method (CVM) to elicit farmers’ Willingness to Pay (WTP) for eliminating the risks of crop loss by accessing improved irrigation schemes. Data for the analysis were gathered using a double bounded survey from over 200 randomly-sampled farmers in 15 villages. The study makes a contribution to the applied welfare literature and should also be useful for policymakers in Africa. The policy contribution consists of valuation of improved irrigation in the presence of climate change risks. The applied welfare contribution consists of...

Willingness to Pay for Emission Reductions with E85 AgEcon
Jensen, Kimberly L.; Marra, Adrienne; Clark, Christopher D.; English, Burton C..
This study examines consumers' WTP for reductions in greenhouse gas emissions from E85 as opposed to gasoline. Data were collected via a contingent choice exercise in a 2009 national online survey. As part of the fuel choice exercise, several fuel attributes were allowed to vary including emission reductions, import level, proximity of fuel availability, price, and fuel blend (E85 or regular gasoline). A random parameters model with demographics and attitudes interacted with emission reductions was estimated. The resulting estimates suggest that, overall the WTP for an emission reduction is not statistically significant. However, for some demographic and attitudinal profiles, the WTP is significant. An example profile includes younger age, female,...

Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop: A Stated Choice Approach AgEcon
Fewell, Jason E.; Bergtold, Jason S.; Williams, Jeffery R..
Farmers’ Willingness to Grow Switchgrass as a Cellulosic Bioenergy Crop: A Stated Choice Approach Agriculture’s role as a source of feedstocks in a potential lignocellulosic-based biofuel industry is a critical economic issue. Several studies have assessed the technical feasibility of producing bioenergy crops on agricultural lands. However, few of these studies have assessed farmers’ willingness to produce or supply bioenergy crops or crop residues. Biomass markets for bioenergy crops do not exist, and developing these markets may take several years. Therefore, an important, yet unaddressed question is under what contractual or pricing arrangements farmers will grow biomass for bioenergy in these nascent markets. The purpose of this paper is to examine...

Empirical Evidence Showing The Relationships Between Three Approaches For Pollution Control AgEcon
Wilson, Clevo.
Willingness to pay models have shown the theoretical relationships between the contingent valuation, cost of illness and the avertive behaviour approaches. In this paper, field survey data are used to compare the relationships between these three approaches and to demonstrate that contingent valuation bids exceed the sum of cost of illness and the avertive behaviour approach estimates. The estimates provide a validity check for CV bids and further support the claim that contingent valuation studies are theoretically consistent.

Consumer Acceptance of Genetically Modified Foods in Taiwan: Is Positive Discount the Same as Negative Premium? AgEcon
Kaneko, Naoya; Chern, Wen S..
This paper finds Taiwanese consumers' willingness to pay a premium on the non-GM food differs from their willingness to accept a discount on the GM food. It further finds that the non-GM choosers are more committed to the non-GM food than the GM choosers to the GM food.

Measuring Market Potential for Fresh Organic Fruit and Vegetable in Ghana AgEcon
Owusu, Victor; Owusu, Michael Anifori.
This paper examines the market potential for fresh organic lettuce and water melon with a recently collected data on consumers from Kumasi metropolis of Ghana. Using a doublebounded dichotomous choice contingent valuation technique, consumer’s willingness to pay is estimated with a Tobit model to address the zero willingness to pay responses in the sample data. As much as 71% of the consumers are willing to pay over 50% price premiums for organic vegetables and over 82% are willing to pay 1%–50% price premiums for organic fruits. The empirical results indicate that human capital, product attributes and consumer perception influence consumers’ willing to pay for organic food products. The estimated market potential for organic fruit is GH¢32,117,113 (US$...

The Influence of Endogenous Nutrition Knowledge on Consumers’ Willingness-To-Pay for Grass-Fed Beef AgEcon
Xue, Hong; Mainville, Denise Y.; You, Wen; Nayga, Rodolfo M., Jr..
The relationship between nutrition knowledge and consumers’ food behavior has been debated for years. This may be partially attributed to the difficulty introduce by endogeneity of nutrition knowledge in econometric modeling. Using grass-fed beef as a vehicle, this paper investigates the impacts of consumers’ nutrition knowledge on their willingness to pay by accommodating the endogeneity problem using instrumental variable approach. Our results suggest that consumers’ nutrition knowledge significantly influences their willingness to pay for grass-fed beef. Gender and education are influential factors of consumers’ nutrition knowledge level.

Combining Consumer Valuation Research with Sensory Science Techniques: A Laboratory Experiment AgEcon
Gustafson, Christopher R.; Lybbert, Travis J.; Sumner, Daniel A..
In this research, we integrated an experimental auction with sensory science techniques—namely, trained sensory panels used to analyze the sensory attributes of wines—to examine the effects of objective and sensory information in the market for California-produced Cabernet Sauvignons. The experiment permitted observation of consumer valuation for sensory attributes of wine, appellations, expert ratings, and wineries. Participants submitted bids each time they received new information about the wines. The balanced experimental design permits evaluation of the effects of consumer characteristics on attribute valuation. We had 236 people participate in the research, which consisted of nine rounds of bidding and one round of hedonic liking scores. Rounds...

Emerging Markets for GM Foods: A Study of Consumer's Willingness to Pay in India AgEcon
Deodhar, Satish Y.; Ganesh, Sankar; Chern, Wen S..
A random utility approach is used to estimate logit equations which indicate what factors affect the likelihood of consumption of non-GM and GM foods, and, whether or not consumers are willing to pay a premium for non-GM/GM foods. Ceteris paribus as the price difference between non-GM and GM food rose, people were more likely to consume GM foods. Likelihood of GM food consumption was higher in the middle income brackets. Consumers were willing to pay an expected premium of 19.5% and 16.12% for golden rice and GM edible oil respectively. In case of chicken, consumers seemed to pay a very negligible premium for non-GM fed chicken. Overall, it appears that GM foods may be acceptable in the Indian market. However, basic awareness about the GM foods may...

Modeling Certainty-Adjusted Willingness to Pay for Ecosystem Service Improvement from Agriculture AgEcon
Ma, Shan; Lupi, Frank; Swinton, Scott M.; Chen, Huilan.
The public demand for ecosystem services measured by willingness to pay (WTP) in contingent valuation studies provides important information for designing Payment-for-Ecosystem-Service (PES) programs. However, the hypothetical markets for contingent valuation and respondents’ unfamiliarity with certain ecosystem services may increase their preference uncertainty, which may increase variance and even cause bias in WTP estimates. Taking advantage of a unique stated preference data set that includes a follow-up question rating the respondent’s certainty level, this study evaluates alternative methods of modeling certainty-adjusted WTP for cleaner lakes and abated global warming. Results suggest that the incorporation of self-reported uncertainty into binary...

Valuing Farmland Protection with Choice Experiments That Incorporate Preference Heterogeneity: Does Policy Guidance Depend On the Econometric Fine Print? AgEcon
Johnston, Robert J.; Bergstrom, John C..
Although mixed logit models are common in stated preference applications, resulting welfare estimates can be sensitive to minor changes in specification. This can be of critical relevance for policy and welfare analysis, particularly if policymakers are unaware of practical implications. Drawing from an application to agricultural conservation in Georgia, this paper quantifies the sensitivity of welfare estimates to common variations in mixed logit specification and assesses practical implications for policy guidance. Results suggest that practitioners may wish to reevaluate modeling and reporting procedures to reflect the welfare and policy implications of common but often unnoticed variations in model specification.
