As in many high-income countries, there is increasing awareness towards organic farming in many low- and middle-income countries. Sustained local demand is an essential requirement for further adoption of organic farming by smallholders, who typically have only limited access to export markets. Until now, only few studies have explored the local willingness to pay (WTP) for organic products in low- and middle-income countries in real purchase situations. This paper analyses the consumers' WTP for organic rice in urban and suburban Indonesia using an incentive-compatible auction based on the Becker–DeGroot–Marschak (BDM) approach. We further study the effect of income and a randomised information treatment about the benefits of organic food on respondents' WTP. Estimates suggest that respondents are willing to pay an average price premium of 20% compared with what they paid for conventional rice outside our experiment. However, our results also indicate that raising consumers' WTP further is complex. Showing participants a video about health or, alternatively, environmental benefits of organic food was not effective in further raising WTP. The results can be used as a basis for the design of alternative awareness measures to increase knowledge, interest and demand for organic food. 相似文献

ABSTRACT This study examines consumers' willingness to purchase pesticide-free fresh produce (PFFP) in Canada's Maritime Provinces. Households' decisions in purchasing organic foods are reflected in their willingness-to-pay (WTP) a premium for obtaining these types of products. WTP was modeled as a function of a series of explanatory variables including sociodemographic, socioeconomic, media, and public awareness about the impact of pesticide use on health and environment. Results suggest that Maritimes' consumers tend to pay the premium because they believe that the use of pesticide in conventional farming is life threatening. In addition, males and individuals with bachelor degrees are more willing to pay the premium, but those who visit farmers' markets on a regular basis are less likely to pay a premium for pesticide-free fresh fruit and vegetables. Finally, results show that media have no impact on consumers' decisions to purchase pesticide-free fresh produce. 相似文献

The discovery of bovine spongiform encephalopathy (BSE), commonly known as ‘mad cow disease’, in Japan caused anxiety about consuming beef and beef products. As a result, there was a sudden fall in sales of beef that hurt the Japanese beef industry as well as major beef exporters to Japan. We analyse factors that affect Japanese consumers' willingness to pay (WTP) price premiums for BSE‐tested beef and estimate the mean WTP for BSE‐tested beef using data obtained from a consumer survey in Japan. A single‐bounded dichotomous choice contingent valuation model is used to recover the premium amount. We find that attitudes to food safety, reduction in beef consumption following the BSE outbreak, and being female all have a statistically significant positive effect on the WTP for BSE‐tested beef. Interestingly, demographic variables such as age and income do not affect the WTP, possibly indicating that the BSE scare similarly affected multiple segments of the population. In our sample, consumers are willing to pay a premium on average of greater than 50 per cent for BSE‐tested beef. 相似文献

Genetically modified (GM) crops are popular in many regions of the world, but their deployment in Africa is hindered by safety concerns and regulatory issues, although the continent is in dire need of boosting its food production. Although consumers' acceptance of GM food has been analyzed in many continents, no such studies have been conducted in Africa. Therefore, a survey of 604 consumers was conducted in Nairobi, Kenya, in 2003, to gauge consumers' awareness of GM crops, their willingness to pay (WTP) for GM food, and the factors that influence their WTP. Consumers' knowledge of GM crops was limited and only 38% of the 604 respondents were aware of GM crops. People in higher education and income groups were more aware than others. Regardless, people were generally appreciative of the technology, and a large majority (68%) would be willing to buy GM maize meal at the same price as their favorite brand. Consumers were, however, concerned about possible side effects, especially on the environment and biodiversity. WTP was estimated using a double‐bounded dichotomous choice model, and the mean WTP was found to be 13.8% higher than the average price of non‐GM maize meal. Perceptions of health risk, and ethical and equity concerns had a negative influence on the likelihood of purchasing GM maize meal, whereas trust in government to ensure food quality had a positive influence on WTP. People with at least some secondary education and those in the high‐income category were more likely to purchase GM maize meal at the same price. The study concludes that, because awareness is still low, appropriate communications are needed to involve the consumer in the debate. Consumers' acceptance in this study was high, but the research needs to be expanded to rural areas, where most consumers live, and other survey methods need to be explored. 相似文献

Livestock products, such as dairy and beef, are increasingly regarded as resource intensive and concerns are raised about animal welfare and environmental sustainability. As a result, consumer awareness of these issues has led to an increasing demand for products with high quality credence attributes (CAs) that cannot be directly experienced or identified. A number of empirical studies have attempted to estimate consumers' willingness to pay (WTP) for CAs, which represents the additional value placed on the benefits that they derive from those products. However, there are significant differences in these WTP estimates, mainly because both consumers' perceptions of CAs and the conditions of the studies vary. We conduct a meta‐analysis to examine consumers' WTP for different CAs of livestock products based on a systematic review of relevant studies. Meta‐regression models are used to control for the heterogeneity of WTP estimates and investigate factors that affect the estimation of WTP. Overall 555 estimates derived from 94 papers reporting WTP are included in this study. Meta‐regression results establish the presence of systematic WTP variation associated with types of products, CAs, and locations, though also indicate that WTP is subject to systematic variation associated with study methodology. 相似文献

AbstractFood safety is one of the main concerns and the biggest challenge for consumers due to its direct influence on human health. In order to deal with unsafe food situation, the demand for food hygiene has increased in recent years as well as the consequent increase in price accepted by consumers. This study aimed to estimate consumers’ willingness to pay (WTP) and to examine the determining factors influencing their WTP for safe pork using double-bounded dichotomous choice contingent valuation method (DBDC CVM). The data were collected from a survey with a sample size of 134 respondents in Hanoi, Vietnam using two sets of questionnaires on the consumption of rib and shoulder of pork. The results revealed that the percentages of the consumers willing to pay a premium for more hygiene shoulder and rib of pork were 81.75% and 73.01%, respectively. The mean WTP was 129,000 VND (US$6.07) for both safe shoulder and rib, 48.7% and 37.8% higher than the regular market price, respectively. The results showed that consumers’ awareness of the risk of unhealthy pork, household income and expenditure were the positive determinants to WTP; meanwhile, the amount of pork consumption per month negatively affected the willingness to pay more for shoulder and rib of pork. 相似文献

We conduct a series of Becker–DeGroot–Marschak (BDM) auctions to elicit consumers' willingness‐to‐pay (WTP) for organic and local blueberries. Participants' intentions to purchase the auction product were collected to determine how purchase intentions for the auction products affect their partial bids (WTP for an additional attribute) as well as full bids (WTP for the auction product). The results suggest, as expected, that full bids from participants with purchase intention for the auction product are significantly higher than those from participants without purchase intention. However, the partial bids, which are inferred from the full bids, for organic and local attributes are consistent across participants with different purchase intentions. Therefore, if the focus of a BDM auction is consumers' WTP for product attributes, purchase intentions may not be an important influence on the value. 相似文献

In the analysis of stated preferences studies, it is often assumed that protesting is a discretely measured item only occurring among those who are not willing to pay. However, various studies have recently shown that protest beliefs are as well held by respondents who state a positive willingness to pay (WTP). Using latent class (LC) models, we investigate the extent of heterogeneity with respect to protest beliefs among all respondents of two contingent valuation studies. The advantage of LC models is that classes of individuals are endogenously identified and no selection bias is introduced by ad hoc definitions of protesters. Further we investigate whether it is possible to identify a class of non‐protesters. Finding a group of pure non‐protesters could indicate how strongly stated WTP in the whole sample is affected by protest beliefs. For both samples, we find a class with strong protest beliefs but no pure non‐protest class. Overall, our results suggest that LC models might not be the first choice to determine unbiased WTP measures, but they provide valuable insights into the degree of protesting expressed by different groups and corresponding determinants of group membership. 相似文献

The major objective of this study is to estimate Korean food shoppers’ willingness to pay (WTP) for imported beef with traceability. We use an experimental elicitation method, the random nth price auction, to identify consumers’ valuation for traceable imported beef. We also analyse the effect of different types of information on these valuations. Results indicate that consumers are generally willing to pay a 39 per cent premium for the traceable imported beef over similar beef without traceability. Results also suggest that in contrast to the insignificant effect of positive information, negative and two‐sided information about traceability significantly reduces WTP. 相似文献

Studies have combined contingent valuation and attitude theory in models directly predicting willingness to pay recreation fees. Little research, however, has modeled predictions of attitudes toward fees on both the intention to pay (WTP) and stated payment amount ($WTP) simultaneously. This article addresses that knowledge gap using onsite survey data from 1068 recreationists at the McDonald-Dunn forest in Oregon. Attitudes toward paying an annual fee at this forest were directly associated with WTP and were among the strongest predictors of WTP. Respondents with supportive attitudes toward paying the annual fee were more willing to pay than those who were opposed. The strength of attitudes also influenced WTP, with those respondents having stronger opposition being least likely to pay. Attitudes toward paying a fee were indirectly (i.e., mediation) related to the stated payment amount ($WTP), suggesting that payment is influenced by intention to pay (WTP), and this intention is partially a function of attitudes about fees. 相似文献

This paper examines the value of reducing foodborne risk. Previous research on the valuation of health risk has been dominated by the study of mortality risk. However, in most cases foodborne illnesses are non‐fatal, so we focus on individuals' preferences for reducing morbidity risk, while also including a realistic, if remote, chance of death. We use a contingent valuation method on a Swedish sample and we estimate a value of a statistical illness consistent with previous findings in the literature. We also examine how willingness to pay (WTP) varies with the expected change in quality‐adjusted life years (QALYs) and estimate the WTP per QALY. We find that WTP increases with, though less than proportionally to, a change in QALYs. However, our results also suggest that respondents may have found it difficult to evaluate compound risks of both morbidity and mortality simultaneously. 相似文献

Could the future French eco‐label for fresh seafood products find its place in the French market? This study employs a contingent valuation method to estimate French consumers’ willingness‐to‐pay (WTP) for eco‐labeled fresh seafood products. We exploit original data from a survey carried out in 2010, where 626 participants responded to a double‐bounded dichotomous choice model, through an ascending or descending bid system. Controlling for shift and anchoring effects in random effect probit models, we significantly improve estimation of WTP and its determinants for the three species studied (monkfish, lobster, sole), in particular when using heterogeneous anchoring. We show that WTP is positively correlated to respondents’ income, and also to their environmental concern, to living alone, to living far from the coast, and to trusting NGOs or public institutions more than producer organizations to implement an eco‐label. We also show that the mean price premiums do not differ between species. Finally, on average, the maximum premium consumers accepted to pay is approximately 10% of the product price. 相似文献

Abstract This study explores the economic benefit from labeling milk and milk products and its impact on the supply and demand for fluid milk. The empirical estimate measures the economic value of milk market segmentation based on consumers' willingness to pay for hormonefree milk. The study uses survey data from Kansas households and applied a Probit model for willingness-to-pay and an ordinary least square model for demand analysis. The empirical results show that as long as consumers are willing to pay a higher price for bSTfree milk society would benefit from milk market segmentation. 相似文献

Credence attributes such as environmental impact, origin, fairness/unfairness, and food safety/health are not available with certainty prior to or at the time of the consumer purchase decision. This creates a problem of imperfect or asymmetric information, leading to suboptimal supply and demand for products with these desirable attributes. Using a representative sample of 2001 Canadian consumers, we adopt, within an attribute-based decision-making framework, the asymptotically efficient double-bounded stated preference approach, to estimate Canadian consumers' willingness to pay for origin, fairness, environmental impact, and food safety attributes associated with pork chops and fresh apples. We find that, on average, consumers are willing to pay significantly more for pork chops and fresh apples that are farmers-advantaged, sourced from their own province, grown or raised under a production system designed to be environmentally sustainable, and chemical-free. However, these findings differ significantly by the province of origin, gender, age, and income of the respondents, as well as by product type and attributes being valued. 相似文献

Aflatoxins are a common health hazard in tropical countries, especially in rural areas. New methods to reduce aflatoxin levels in food staples, as well as cheaper test methods, are being developed, but consumers’ willingness to pay (WTP) for these improvements is unknown. A survey was conducted with a representative sample of rural consumers (1,344 in total, 63% women) in all major maize‐production zones of Kenya. The survey included an experimental auction with maize products of different qualities. The results showed that many rural consumers were aware of aflatoxins, but few understood their health risks. Respondents were willing to pay a premium for maize tested for aflatoxins and labeled, but asked a high discount for maize that was visibly contaminated with moldy grain. The premium was higher for respondents with education and in regions with aflatoxicosis outbreaks. Knowledge of aflatoxins substantially reduced the overall WTP, but did not increase the WTP for tested maize. Welfare analysis indicates that mandatory testing would result in substantial benefits if the cost of testing can be lowered to below the premium. 相似文献

The aim of this paper is to introduce an approach to estimating the marginal willingness to pay (WTP) for food quality and safety using data on actual consumer purchases. Marginal WTP for specific food product varieties can be derived from estimated demand functions by inverting the relations, thereby expressing the prices consumers are willing to pay as functions of quantity demanded. The task addressed in the paper is isolation of the WTP for quality attributes embedded in the varieties. Two models based on the AIDS-specification are proposed and discussed. To illustrate the applicability of the models, the case of five varieties of eggs is presented. It is found that Danish consumers are willing to pay a relatively high premium for improved animal welfare and organic production methods and somewhat less for food safety. 相似文献

Consumers’ willingness to pay (WTP) price premiums for environmentally certified wood products has been frequently estimated using stated preference methods. Estimates of WTP premiums for certified wood products over non-certified options reported in the literature range from 1.0% to 39.3%. This paper describes a meta-analysis used to determine the key factors associated with WTP price premium estimates by examining data from 19 different studies conducted around the world. Results of Bayesian hierarchical models show that frequently purchased wood products and wood products with lower base prices tend to capture higher percentage premiums. Survey administration method was also a statistically significant factor influencing variations in WTP estimates. Results show that conjoint analysis elicited inflated WTP estimates toward certified wood products compared with contingent valuation methods. Reported WTP estimates have increased in recent years. Recommendations to reduce the error of WTP estimates toward certified wood products and improve the validity of experimental studies are provided. 相似文献

Using data collected from a survey conducted in Jiangsu Province, China, we study consumer perceptions of and attitudes toward food traceability systems (FTS). Through econometric analysis, we examine the main factors that influence the willingness of consumers to pay a price premium for certified traceable food, as well as the actual premium these consumers are willing to bear. Our results indicate that an overwhelming majority of consumers in China are concerned about food safety, but consumers’ willingness to pay (WTP) a price premium for certified traceable food is limited. Income, education, perception of and attitudes toward FTS, as well as the degree of concern over food safety, have significant effects on the consumer's WTP a price premium for certified traceable food. However, the effects of these factors on the actual premium a consumer is willing to pay are quite different. Conditioned on the consumer being willing to pay a positive price premium, income level and the degree of concern over food safety are the only two factors that have significant effects on the actual premium consumers are willing to pay. À partir de données tirées d’un sondage mené dans la province du Jiangsu, en Chine, nous avons étudié la perception et l’attitude des consommateurs envers les systèmes de traçabilité des aliments. À l’aide d’analyses économétriques, nous avons examiné les principaux facteurs qui influencent le consentement des consommateurs à payer un prix supérieur pour des aliments dont la traçabilité est certifiée ainsi que le prix réel qu’ils sont prêts à payer. Les résultats de notre étude indiquent qu’une très grande majorité de consommateurs en Chine sont préoccupés par la sécurité alimentaire, mais que leur consentement à payer un prix supérieur pour des aliments dont la traçabilité est certifiée est limité. Le revenu, le niveau de scolarité, la perception et l’attitude envers les systèmes de traçabilité, de même que le degré de préoccupation concernant la sécurité alimentaire, ont des effets considérables sur le consentement des consommateurs à payer un prix supérieur pour des aliments dont la traçabilité est certifiée. Toutefois, les effets de ces facteurs sur le prix réel qu’un consommateur est prêt à payer sont très différents. Lorsque des consommateurs consentent à payer un prix supérieur, le niveau de revenu et le degré de préoccupation concernant la sécurité alimentaire sont les deux seuls facteurs qui influencent fortement le prix réel qu’ils sont prêts à payer. 相似文献

Using online surveys to elicit consumer preference is gaining popularity because of several advantages offered by this method. Past research mainly focuses on the comparison between online surveys and other survey modes. Few have explored methods of using online survey tools to improve data quality for consumer willingness‐to‐pay (WTP) estimates. This article determines the impact of using a validation question (VQ) approach that asked survey respondents to select a particular answer on improving online survey data quality across six countries. Results show that survey data quality is a common problem in online surveys across countries and the severity of this problem differs significantly. Using VQs might detect the respondents who are less careful in answering survey questions, thus providing less reliable answers. The econometric models for respondents who correctly answer VQs (pass VQs) perform significantly better than the models for respondents who incorrectly answer VQs (fail VQs). The WTP estimates for respondents who pass and fail VQs differ significantly; and in general the WTP estimates for respondents passing VQs have smaller variances than those for all respondents and for respondents failing VQs. 相似文献
