Using a Modified Payment Card Survey to Measure Chinese Consumers’ Willingness to Pay for Fair Trade Coffee: Considering Starting Points

Coffee consumption in China has increased rapidly in recent years. This study offers one of the few existing attempts to understand Chinese consumers’ coffee consumption behavior with a special focus on the viability of fair trade coffee in the Chinese market. A modified payment card approach was adopted to elicit consumer willingness to pay (WTP). Survey results suggest a positive attitude toward coffee and WTP for fair trade coffee. This study also explores the potential impact of starting point bias, which has been relatively well documented in the dichotomous choice literature, but less thoroughly in a payment card context. La consommation de café en Chine s’est accrue rapidement au cours des dernières années. La présente étude figure parmi les quelques tentatives déployées pour comprendre le comportement de consommation de café des consommateurs chinois et se penche sur la viabilité du cafééquitable sur le marché chinois. Nous avons utilisé une méthode modifiée de la carte de paiement pour déterminer le consentement à payer des consommateurs. Les résultats de notre étude montrent une attitude positive envers le café et un consentement à payer pour obtenir du cafééquitable. L’étude se penche également sur l’impact probable du biais de position initiale, qui est assez bien documenté dans la littérature sur le choix dichotomique, mais qui l’est moins dans le contexte de la carte de paiement.     

Willingness to Pay for Pesticide Free Fruits: Evidence from Pakistan

ABSTRACT

This paper analyzes factors influencing consumption decision of pesticide free fruits (PFF) and estimates the willingness to pay (WTP) price premium for PFF in Pakistan. A contingent valuation survey of 200 households was conducted using face to face interview and payment card method. Results suggested that 93.5% respondents were WTP higher prices for PFF. Remarkably, around 35% respondents were WTP 16–20% higher prices and 24% respondents were WTP 6–10% higher prices for PFF than the existed conventional price. In addition, our ordered logit regression suggests that demographic and socio-economic variables such as age, education, income, household’s size and perception about health benefits are significantly associated with higher WTP for PFF.     

Farmers’ Willingness to Pay for a Tuberculosis Cattle Vaccine

We use contingent valuation (CV) and choice experiment (CE) methods to assess cattle farmers’ attitudes to and willingness to pay (WTP) for a bovine tuberculosis (bTB) cattle vaccine, to help inform vaccine development and policy. A survey questionnaire was administered by means of telephone interviews to a stratified sample of 300 cattle farmers in annually bTB‐tested areas in England and Wales. Farmers felt that bTB was a major risk for the cattle industry and that there was a high risk of their cattle getting the disease. The CE estimate produced a mean WTP of £35 per animal per single dose for a vaccine that is 90% effective at reducing the risk of a bTB breakdown and an estimated £55 for such a vaccine backed by 100% insurance of loss if a breakdown should occur. The CV estimate produced a mean WTP of nearly £17 per dose/per animal/per year for a vaccine (including 100% insurance) which, given the average lifespan of cattle, is comparable to the CE estimate. These WTP estimates are substantially higher than the expected cost of a vaccine which suggests that farmers in high risk bTB ‘hotspot’ areas perceive a substantial net benefit from buying the vaccine.     

消费者对转基因食品的意愿支付:来自上海的经验证据

转基因食品在全世界引起激烈争论。了解消费者对于转基因食品的态度和接受程度，对于制定转基因食品的管制政策具有十分重要的作用。国外的研究使用了多种的方法估计消费者对转基因食品的态度，国内的研究还很少见。本论文使用假设评价法，通过对上海市300个家庭问卷调查，发现人们对于转基因食品的认知程度还比较低，普及农业生物科技知识非常必要。尽管消费者认为自己非常关注食品安全和营养问题，但在实际购买中，他们更多的考虑还是价格和收入。上海消费者对于为转基因加贴特殊标签持较强烈的支持态度，对转基因植物食品的反感程度要小于对转基因动物食品的反感程度。二元10git回归的结果表明，在传统大豆和转基因大豆烹调油之间，消费者更倾向于购买非转基因食品，而且只有当转基因食品的价格平均比非转基因的价格低28．55％时，消费者才愿意购买转基因食品。     

Willingness to Pay versus Expected Consumption Value in Vickrey Auctions for New Experience Goods

Over the past two decades, Vickrey auctions have been widely used to elicit willingness to pay for new food products. This article shows that in a multiperiod context, it can be optimal for consumers to bid higher than the expected consumption value for a new experience good to obtain information about how the new good fits into their preference set. The degree of uncertainty about the consumption value, the purchasing frequency, and expected future market prices affect both the expected value of the quality information and the subgame perfect bidding strategy in Vickrey auctions for new experience goods.     

U.S. Consumers’ Preference and Willingness to Pay for Country‐of‐Origin‐Labeled Beef Steak and Food Safety Enhancements

While previous studies have investigated country‐of‐origin effect from various angles, the extent to which Country‐of‐Origin Labelling (COOL) affects U.S. beef imports from specific countries remains unexplored. Using data from 1,079 consumers from the United States, we examined consumers’ willingness to pay (WTP) for Canadian and Australian beefsteaks. We also estimated WTP for bovine spongiform encephalopathy (BSE)–tested traceability‐enabled, tenderness‐assured, and natural beef. The results from both a mixed logit model and a latent class model (LCM) revealed unobserved taste heterogeneity and important differences in the WTP between the imported and domestic steak. The LCM, for instance, estimated the range of discount needed for consumers to switch from U.S. to Canadian steak as $1.09 to $35.12 per pound. This strongly suggested that U.S. consumers prefer domestic‐originated beef to imported beef. In addition, consumers were found to be willing to pay significant amount for BSE‐tested, traceability‐enabled, and tenderness‐assured beef. Bien que des études antérieures aient examiné les répercussions de l’étiquetage du pays d’origine sous différents angles, les répercussions de cet étiquetage obligatoire sur les importations étatsuniennes de b?uf en provenance de pays spécifiques ne l’ont pas été. À l’aide de données tirées d’un échantillon de 1079 consommateurs étatsuniens, nous avons examiné le consentement à payer (CAP) pour du bifteck en provenance du Canada et de l’Australie. Nous avons également examiné le CAP des consommateurs pour du b?uf provenant d’un animal ayant subi un test de dépistage de l’ESB, traçable, de tendreté assurée et naturel. Les résultats obtenus à l’aide d’un modèle logit mixte et d’un modèle à classes latentes ont révélé une hétérogénéité non observée du goût et des écarts importants dans le CAP pour du bifteck provenant des États‐Unis et de l’extérieur du pays. Le modèle à classes latentes, par exemple, a révélé que les écarts de rabais nécessaires pour que les consommateurs délaissent le bifteck américain pour le bifteck canadien variaient de 1,09 While previous studies have investigated country‐of‐origin effect from various angles, the extent to which Country‐of‐Origin Labelling (COOL) affects U.S. beef imports from specific countries remains unexplored.

Willingness to Pay for Multiple Quantities of Animal Welfare Dairy Products: Results from Random Nth‐, Second‐Price,and Incremental Second‐Price Auctions

Nonhypothetical experimental auctions are used to elicit willingness to pay for humane animal care‐certified dairy products: cheese and ice cream. We use second‐price, random Nth‐price, and incremental second‐price auctions in multiproduct, multiquantity, and multiround contexts. The results contrast participants’ bids across different auction mechanisms and different products. Differences in bidding patterns are detected across auction mechanisms as well as products. Our results suggest that subjects on average are only willing to pay a premium price for one unit of humane animal case‐certified ice cream but not for multiple quantities.     

The Effects of Selling Complements and Substitutes on Consumer Willingness to Pay: Evidence from a Laboratory Experiment

Basic economic theory predicts that a consumer's willingness to pay for a good is affected by the availability of complements and substitutes. In an auction setting, this theory implies that the presence of complements would increase bid prices for a good, while the presence of substitutes would decrease bid prices for a good. We designed an experiment that allows the calculation of inverse elasticities, the inverse-demand equivalent of conventional price elasticities. Our results show that the availability of complements and substitutes affects bids in the expected directions. This finding has important implications for researchers who design experimental auctions.
Selon la théorie économique de base, la volonté de payer d'un consommateur pour obtenir un bien est influencée par la disponibilité de compléments et de substituts. Dans un scénario de vente aux enchères, cette théorie implique que la présence de compléments ferait augmenter le prix offert pour un bien, tandis que la présence de substituts ferait diminuer le prix offert. Nous avons conçu une expérience qui a permis de calculer les élasticités inverses, l'équivalent de la demande inverse des élasticités-prix classiques. Nos résultats ont montré que la disponibilité de compléments et de substituts influence les offres d'achat dans les directions prévues. Cette observation a d'importantes répercussions pour les chercheurs qui conçoivent des ventes aux enchères expérimentales.     

Consumer Willingness to Pay for Dairy Products With the 100% Canadian Milk Label: A Discrete Choice Experiment

ABSTRACT

A component of the supply management policy governing the Canadian dairy sector is a requirement that all milk and cream sold in Canada be sourced from Canadian producers. Cheese, yogurt, and ice cream, however, can be made using imported milk components. Recently, the Dairy Farmers of Canada launched a 100% Canadian Milk label for products that contain only milk and milk ingredients produced in Canada. Featuring a discrete choice experiment, a Canada-wide survey of dairy consumers is used to elicit their willingness-to-pay for milk and ice cream carrying the 100% Canadian Milk label. The results show that Canadian consumers are willing to pay more for milk and ice cream products that carry the label. Consumer knowledge of the dairy sector affects their willingness to pay for this labeling information. Implications for the use of the Canadian origin label and suggestions for further research are discussed.     

A Meta-analysis of the Willingness to Pay for Cultural Services from Grasslands in Europe

We investigate the willingness to pay (WTP) for cultural ecosystem services from grasslands using a meta-analysis based on 32 eligible research papers that provide in total 79 estimates. The average WTP (corrected for purchasing power) across these studies is 38 Euros per person per year. Yet, our analysis reveals that the transfer of these results needs careful evaluation. More specifically, it is essential to frame the monetary valuation exercise in relation to the direction of grassland change. A switch from cropland to grassland reduces WTP by 90 Euros while an increase in less-intensive land-use in mountain regions raises WTP by 53 Euros. We conclude that for an adequate consideration of grasslands in holistic ecosystem services assessments, the direction of grassland change is important.     

Beef Credence Attributes: Implications of Substitution Effects on Consumers’ WTP

Consumers’ food choices are influenced by a wide variety of credence attributes, but the food industry faces problems assessing whether the price premiums that consumers are willing to pay for these attributes will be sufficient to offset higher production costs. In this context, consumers’ willingness to pay (WTP) for safer, cleaner and animal friendlier beef was investigated through a choice experiment. The relative importance of WTP for these attributes shows that consumers place the highest values on food safety, followed by animal welfare and finally environmental protection. WTP for different combinations of the three attributes cannot be obtained by independent valuation and summation due to the presence of significant substitution relationships. However, some suggestions for the relationships between these attributes can be proposed through an after‐survey analytical solution. The bias involved in separately valuing closely related attributes can potentially jeopardise the success of a differentiation strategy.     

Consumers’ Appreciation of Regional Certification Labels: A Pan‐European Study

Successful regional products, such as Florida oranges, Idaho potatoes and Parma ham, often have to compete against products passing themselves off as the authentic product using the exact same name. This unfair competition misleads consumers, discourages small‐ and medium‐sized enterprises (SMEs) from marketing products based on their region of origin, and may end up hurting rural economies. To protect consumers, and support SMEs and rural economies, many countries around the world have introduced regulations enabling SMEs to legally protect the names of their regional products. The success of these regulations largely depends on consumers’ appreciation of regional certification labels that inform consumers that the name of the regional product is protected and that it denotes the authentic product. To gain an understanding about consumers’ appreciation of regional certification labels, this paper investigates consumers’ image of these labels and proposes a model that relates this image to consumers’ willingness to buy and pay for protected regional products. The model is tested based on Regulation No. 2081/92 that was introduced by the EEC allowing European SMEs to protect their regional products and market their products with a protected‐designation‐of‐origin (PDO) label. Structural equation modelling results suggest that consumers’ image of regional certification labels consists of a quality warranty dimension and an economic support dimension, which positively relate to consumers’ willingness to buy and pay for the protected regional product. Protecting regional products and marketing them with regional certification labels may be beneficial for SMEs producing and marketing regional products. Policy and managerial implications are discussed.     

Willingness to Pay for Rural Landscape Improvements: Combining Mixed Logit and Random‐Effects Models

This paper reports the findings from a discrete‐choice experiment designed to estimate the economic benefits associated with rural landscape improvements in Ireland. Using a mixed logit model, the panel nature of the dataset is exploited to retrieve willingness‐to‐pay values for every individual in the sample. This departs from customary approaches in which the willingness‐to‐pay estimates are normally expressed as measures of central tendency of an a priori distribution. Random‐effects models for panel data are subsequently used to identify the determinants of the individual‐specific willingness‐to‐pay estimates. In comparison with the standard methods used to incorporate individual‐specific variables into the analysis of discrete‐choice experiments, the analytical approach outlined in this paper is shown to add considerable explanatory power to the welfare estimates.     

Sustainable Urban Landscaping: Consumer Preferences and Willingness to Pay for Turfgrass Fertilizers

Residential lawns provide diverse benefits, including social (e.g., enhancing humans’ physical and psychological well‐being), economic (e.g., increasing real estate values), and environmental (e.g., supporting local ecosystems) benefits. However, improper lawn fertilizer applications can cause adverse environmental consequences, such as excessive chemical runoff into adjoining watersheds leading to water contamination. Currently, the importance of eco‐friendly fertilizers to homeowners has not been assessed. This study uses a discrete choice experiment to test whether eco‐friendly fertilizer attributes influence homeowners’ preferences for sustainable landscape management. The findings show that eco‐friendly fertilizer attributes positively influence homeowners’ preferences and willingness to pay, supporting the premise that the promotion of eco‐friendly fertilizer features could improve local ecosystems through increased adaptation. Furthermore, this study tests whether certain fertilizer attributes influence homeowners’ preferences in states with and without fertilizer restrictions. Since the regulatory environment affects homeowners’ preferences for sustainable landscaping, this study compares the results between regulated and unregulated states. The findings reveal that homeowners are more likely to use and are willing to pay higher premiums for sustainable fertilizers in states with residential fertilization regulations. This suggests that with strict fertilizer ordinances, homeowners are more geared toward eco‐friendly landscaping options and that related educational programs should be made available. Les pelouses résidentielles offrent divers avantages, incluant les avantages sociaux (comme la valorisation du bien‐être physique et psychologique humain), économiques (comme la valeur immobilière), et environnementaux (comme l'appui des écosystèmes locaux). La mauvaise application des fertilisants a parfois des conséquences environnementales négatives comme le ruissellement chimique excessif dans les bassins hydrographiques attenants menant à la contamination des sources d'eau. En raison de l'importance des fertilisants respectueux de l'environnement pour la protection de ce dernier, cette étude emploie une expérience avec choix discrets pour évaluer si les attributs écologiques des fertilisants influencent les préférences des consommateurs et leur volonté de payer pour une gestion durable de l'aménagement. Les résultats indiquent que les attributs écologiques des fertilisants influencent positivement les préférences des consommateurs et leur volonté de payer, appuyant ainsi la prémisse selon laquelle la promotion des attributs écologiques des fertilisants de gazon pourrait améliorer les écosystèmes locaux. De plus, cette étude évalue l'influence des attributs de certains fertilisants sur les préférences des propriétaires résidentiels dans les états avec et sans restrictions sur l'application des fertilisants. Puisque le cadre règlementaire peut avoir un impact sur les préférences des consommateurs pour une gestion durable de l'aménagement paysager, cette étude compare les prévisions des états avec et sans cadre règlementaire. Les résultats démontrent que les consommateurs sont plus aptes à utiliser, et sont disposés à payer un surplus pour les fertilisants durables dans les états où des règlements concernant l'utilisation de fertilisants résidentiels sont en vigueur, portant donc à croire que les programmes éducatifs concernant l'aménagement paysager respectueux de l'environnement devraient être accompagnés d'ordonnances strictes en matière de fertilisants.     

Consumer Willingness to Pay for Cue Attribute: The Value Beyond Its Own

Using Certified U.S. Product as a product cue, we show that consumer willingness to pay for other identifiable search and experience attributes change. Certified U.S. Product serves as a substitute for Guaranteed Tender and a complement of Guaranteed Lean. Results have important implications for policymakers and food companies interested in food labeling programs in the presence of cue attributes such as Certified U.S. Product. The substitute effects of a cue attribute on other product attributes may contribute to deteriorating product quality and the complement effects of a cue attribute could improve product quality in the market.     

Willingness to Pay for Reduced Risk of Foodborne Illness: A Nonhypothetical Field Experiment

This paper focuses on estimating willingness to pay for reducing risk of getting foodborne illness using a nonhypothetical field experiment utilizing real food products (i.e., ground beef ), real cash, and actual exchange in a market setting. Respondents were given information about the nature of food irradiation. Single-bounded and one and one-half bounded models are developed using dichotomous choice experiments. Our results indicate that individuals are willing to pay for a reduction in the risk of foodborne illness once informed about the nature of food irradiation. Our respondents are willing to pay a premium of about $0.77 for a pound of irradiated ground beef, which is higher than the cost to irradiate the product.
Le présent article porte sur l'estimation de la volonté de payer des consommateurs pour diminuer le risque de contracter une maladie d'origine alimentaire. L'étude a été réalisée en effectuant une expérience sur le terrain à l'aide de vrais produits alimentaires (à savoir du bœuf haché), d'argent réel et d'échange réel en situation de marché. Les répondants avaient reçu de l'information sur l'irradiation des aliments. Nous avons mis au point des modèles à une limite et à une limite et demie utilisant la méthode des choix dichotomiques. Nos résultats ont montré que les consommateurs étaient prêts à payer pour diminuer le risque de contracter une maladie d'origine alimentaire, une fois informés sur l'irradiation des aliments. Nos répondants étaient prêts à payer une prime d'environ 0,77$ la livre pour obtenir du bœuf haché irradié, soit une somme supplémentaire supérieure au coût de l'irradiation du produit.     

Consumers’ preferences for fresh broccolis: interactive effects between country of origin and organic labels

While international trade in organic products has grown significantly, understanding consumers’ preferences for imported organic foods has remained limited. This research examines the impact of country‐of‐origin labeling on US consumers’ choices of organic foods. Results show that consumer valuation of domestically produced organic broccoli was significantly higher than that of imported organic broccoli. Adding information about USDA organic certification standards/rules for imported products mildly increases consumer valuation of imported organic broccoli in some cases. These findings suggest that providing such information may have a positive impact on consumer willingness to purchase imported organic products.
