Consumers' Willingness to Pay for Quality and Safety in Clams

The aim of the research is to estimate the potential demand for certified clams in Italy and to investigate the determinants of maximum amount that respondents are willing to pay for this product. Quantitative analysis was used based on 1,067 face-to-face interviews collected in 3 Italian regions in the north bordering the Adriatic Sea (Friuli-Venezia Giulia, Veneto, and Emilia-Romagna) carried out during 2008. The consumers' willingness to pay (WTP) is measured using a contingent valuation method. In order to estimate separately the determinants of the probability that respondents are willing to pay and the maximum that they are willing to pay, a generalization of Tobit model was adopted. The results indicate that consumers are willing to pay a premium price mainly to purchase better quality products. The research provides some initial insight into consumers' WTP that can be useful for certified fish farming.     

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.     

Willingness to Pay for Quality Labeled Meat in a Rural Area

The aim of this study is to identify consumer perceptions and attitudes toward quality labeled pork and beef using cross-sectional consumer data. Given the dramatic changes over the last years in the meat sector as a result of the recent food scares, the study can facilitate better communicating with consumers and gaining insight into their perceptions and behavior toward meat products. A consumer survey was conducted in the rural region of Thessaly in Greece in order to investigate (a) food quality perceptions, (b) attitudes toward pork and beef quality labels, and (c) intentions to purchase higher priced certified pork and beef. The findings suggest that sociodemographic and personal characteristics have an impact on consumer willingness to pay for such products and different market segments can be targeted by marketers and food policymakers.     

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.

居民参与农地保护的认知程度及支付意愿研究——以湖北省为例

作为人类赖以生存和发展的物质基础，农地提供粮食、蔬菜、木材等实物型产品，以及开敞空间、景观、文化服务等非实物型生态服务，为人类带来巨大的社会福利。从社会公众参与农地保护的认知及支付意愿（willingness to pay，WTP）出发，估算农地非市场价值，并将其纳入资源成本核算体系中，不仅能够弥补市场机制作用不足给农地流转决策带来的影响，而且通过提高土地资源农业利用的比较效益，能够缓解我国农地流失形势。文章在调查分析湖北省武汉、宜昌、荆门、仙桃、汉川5市县1255户居民家庭对农地保护认知程度及支付意愿的基础上，运用条件价值评估法对湖北省农地非市场价值进行估算。     

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.     

基于支付意愿的有机食品需求分析

本文以山东省济南等5个城市的588个消费者为调查对象,利用计划行为理论(Theory of Planned Behavior,TPB)研究了消费者有机食品的购买意愿,构建Logit回归模型分析了影响城市消费者购买有机食品的主要因素.研究结果表明,城市消费者有机食品购买意愿受收入状况、对有机食品的信任度、有机食品的价格、消费者对自身健康的关注程度等因素的影响比较显著,而消费者的年龄、文化程度、对环境保护的关注程度等因素影响较弱.

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。     

Estimating Willingness to Pay for Improved Water Quality in the Presence of Item Nonresponse Bias

This article deals with the problem of item nonresponse in contingent valuation surveys using a payment-card method, by applying a grouped-data sample-selection estimation technique that is capable of imputing the missing values conditional upon a respondent's decision to answer a willingness-to-pay question. The advantage of the technique lies in its ability to utilize all of the information in the sample, permitting a more efficient estimation in the presence of item nonresponse bias. The major determinants of willingness to pay appear to be household income, number of children, education, perception of existing water quality, and identification with environmental issues.     

European Consumers' Willingness to Pay for U.S. Beef in Experimental Auction Markets

Consumers' willingness to pay for Irish, Norwegian, U.S. hormone-free, and U.S. hormone-treated beef was studied in an experimental auction market. We ran four simultaneous second-price auctions to elicit efficiently the complete distribution of willingness to pay differences among our four alternatives. Most participants preferred domestic to imported beef, and half the participants preferred Irish to U.S. hormone-free beef. Hormone-treated beef received the lowest mean bid, but 28% of the participants were indifferent or preferred U.S. hormone-treated to U.S. hormone-free beef.

Systematic Variation in Willingness to Pay for Aquatic Resource Improvements and Implications for Benefit Transfer: A Meta-Analysis

Researchers are increasingly considering benefit transfer approaches that allow welfare measures to be adjusted for characteristics of the policy context. The validity and reliability of such adjustments, however, depends on the presence of systematic variation in underlying WTP. This paper describes a meta-analysis conducted to identify systematic components of WTP for aquatic resource improvements. Model results reveal systematic patterns in WTP unapparent from stated preference models considered in isolation, and suggest that observable attributes account for a substantial proportion of the variance in WTP estimates across studies. The analysis also exposes challenges faced in development, estimation, and interpretation of meta-models for benefit transfer and welfare guidance. These challenges remain salient even in cases where the statistical performance of meta-models is satisfactory.
