Chinese consumer demand for food safety attributes in milk products

Little is known about emerging demands for food safety among consumers in developing countries. This study presents results of an investigation of consumer awareness, willingness to pay, and price premiums for milk products manufactured using Hazard Analysis Critical Control Point (HACCP) management, a quality management system used to reduce food safety risks. Chinese food processors initially sought HACCP certification to access export markets, but now HACCP is rapidly being adopted for domestic products and HACCP logos have begun to appear on labels in China. A survey of Beijing consumers found that less than one in five respondents was aware of HACCP, and most who had heard of HACCP had learned about it within the previous year. After receiving information on HACCP nearly all respondents were willing to pay a modest price premium for HACCP-certified products. Products with HACCP labels in Beijing supermarkets sold at a price premium of about 5% over products without such labels, holding other product attributes constant. The results indicate that demand for food safety is emerging as an attribute demanded by Chinese consumers.     

Estimating consumer preferences and willingness to pay for the underutilised indigenous chicken products

Indigenous chicken serves many functions, which include the provision of meat and eggs for home consumption and income from sales. The purpose of this study was to estimate the consumers’ responsiveness to an increase in prices of the indigenous chicken products and how much they are willing to pay for them in the market. The survey was conducted in the selected three regions of Kenya. A total of 930 respondents were interviewed both in the urban and rural areas. Contingent valuation experiment was used in empirical data collection. The two-step Heckman selection model was utilised to analyse consumers decisions and the amount they were willing to pay. The study results revealed that consumers are willing to pay 23.26% per kg more for indigenous chicken meat and 41.53% for eggs. Socioeconomic factors like age, income, education and family size significantly determines consumers’ willingness to pay. Other important factors include the indigenous chicken meat substitutes’ prices, attributes like taste/flavour and the product’s form on purchase. The yolk colour and size of eggs determined the consumers’ willingness to pay. Preferences for indigenous chicken products were found to be high. This information will assist in understanding both the urban and rural consumer’s behaviour. Therefore, useful for the indigenous chicken producers, breeders, marketers and policy makers in developing efficient production and marketing strategies. This would also provide a means of improving food security and livelihoods of the rural poor indigenous chicken farmers.     

Consumers’ valuation for food traceability in China: Does trust matter?

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China.     

Green market expansion by reducing information asymmetries: Evidence for labeled organic food products

We investigate how the provision of objective information about the environmental and health impact of organic labels by policy makers can influence the willingness-to-pay of consumers for labeled organic apples in Flanders (Belgium). Using a stated choice experiment, we initially find that Flemish consumers are willing to pay a positive price premium of some 33 eurocent per kilogram for labeled organic apples. After the provision of information on the actual environmental and health effects of organic apple production, this price premium becomes even more pronounced and increases to 57 eurocent per kilogram. Using a conditional logit model with covariates and a mixed logit model, we find evidence of preference heterogeneity. Also, the effect of information provision is more pronounced for certain groups of consumers such as non-vegetarians, infrequent buyers of organic products and members of a nature protection organization. As such, this paper illustrates that there is a role for policy makers and CSR producers in providing more accurate and reliable information about socially responsible production processes. Moreover, it is important to take the observed preference heterogeneity into account and tailor policies to specific consumer groups.     

Does nutrition information on food products lead to healthier food choices?

This paper examines the link between nutrition label use and consumers’ healthier food choices. Label use is considered for the two main types of labels currently found on food products; nutrition facts panels and nutrition/health claims. This link is tested using a three-equation multivariate probit model. Data were obtained from an ad hoc survey conducted in two medium-sized Spanish cities. The results indicate that the use of nutrition information by consumers, whether this involves the fact panel or the claim labels, does influence consumer choice of healthier food products to the same extent, although different types of consumers use the various types of labels considered.     

Consumers’ willingness-to-pay for food safety labels in an emerging market: The case of fresh produce in Thailand

Food safety systems in emerging markets are currently facing a transformation period, becoming more stringent because of an increasing demand for safer food. Consequently, policy makers need to find strategies to increase food safety while giving the industry time to improve their performance. In Thailand, policy makers have adopted the strategy of upgrading food safety standards gradually. Government and private food safety brands and labels were introduced onto the market but little is known whether Thai consumers have preferences for them or not. This study is aimed at evaluating Thai consumers’ preferences for food safety labels and brands on fresh produce, using a surveyed based on discrete-choice experiments. A sample of 350 Thai consumers was surveyed in Bangkok and Nonthaburi in 2013. Quota sampling according to the shopping outlets and convenience sampling methods were adopted. Two hundred respondents were recruited at fresh-food markets and 150 respondents were recruited at supermarkets. We found that consumers are willing-to-pay more for both government led food safety label and private brands, but that there is high heterogeneity in their preferences. The high degree of social desirability for food safety labels confirms that food safety labelling policy should be supported. However, the provision of information and credibility are vital in order to mitigate the risk of consumer deception by self-claimed labels.     

Value of parsimonious nutritional information in a framed field experiment

This study investigates consumers’ beliefs about the tastiness and healthiness of 173 food items in a framed field experiment designed to mirror a grocery shopping environment. Using data collected from 129 food shoppers in Grenoble, France, demand models are estimated to determine how product choice is affected by price, taste, and perceived healthiness, and how choices change with the provision of objective health information. Unlike previous studies focusing on relatively complex nutrition labels, we elicit and convey health information using simple nutritional indices meant to lower search and cognitive processing costs. The results indicate that consumers are willing to pay for tastier foods and for healthier foods, particularly if the consumers have objective information (as opposed to perceived, subjective information) on nutrient content. The estimates suggest that the value of the type of nutritional information provided in the experiment is €0.98 per day. The figure refers to the daily welfare benefits that arise from being able to make a set of choices that better reflect people’s preferences by receiving the nutrient index information on all 173 food items versus not having such information.     

Do Conspicuous Consumers Pay Higher Housing Premiums? Spatial and Temporal Variation in the United States

This study is the first to examine the relationship between conspicuous demand and housing price dynamics. We hypothesize that conspicuous consumers would want high‐end homes to signal their wealth and this housing consumption behavior would induce greater deviations from fundamental house prices. We test this by using a unique dataset that matches the consumers’ appetite for nonhousing luxury goods from Google Insights for Search to housing premiums that they pay for high‐end houses in U.S. Metropolitan Statistical Areas (MSAs) during 2004–2011. The estimation results demonstrate that controlling for a wide range of MSA demographic and economic characteristics, conspicuous demand has a significant, positive relationship with housing premiums. This relationship varies spatially and temporally. Conspicuous demand has a stronger relationship with a price increase in high‐end homes in MSAs with a steady, higher housing premium than in MSAs with a volatile, lower premium during the boom period. In MSAs with a steady, higher housing premium, the relationship remains significant even during the bust period, potentially contributing to maintaining higher housing premiums.     

Willingness-to-pay for natural,organic, and conventional foods: The effects of information and meaningful labels

Vague food labels and distorted product claims have persisted in the “natural” food industry, while organic claims can be certified by the U.S. Department of Agriculture (USDA). Using experimental methods and a sample of randomly selected subjects, we test food label and information treatment effects on subjects' willingness-to-pay (WTP) for organic, “natural,” and conventional foods. Random nth-price auctions are used to elicit WTP after subjects received one of five randomly assigned information treatments. We find large information effects, including asymmetric cross-market effects for natural and organic foods. Perhaps surprising is that organic premiums increase in response to subjects seeing the “natural” foods industry's perspective on its products. Demographics effects are also important. The results have practical implications for natural and organic food marketing and valuing products where there are vague claims about their attributes.     

Benefit evaluation of the country of origin labeling in Taiwan: Results from an auction experiment

This research is aimed at investigating the consumer’s preference for food produced in Taiwan and the economic benefits for the country of origin labeling (COOL). The study used Vickrey second-price sealed-bid auction to elicit the consumer’s willingness to pay (WTP) for products under COOL. The study compared the bid functions estimated with Tobit model and the premium functions estimated with ordinary least squares (OLS). Due to price affiliation, it is more reliable to use the estimated premium functions. The estimated premiums are 67.5%, 84.7% and 99% for Taiwan products over their alternatives of China olives, China oolong tea, and Vietnam oolong tea, respectively. The study concludes that enacting and rigorously enforcing a COOL law would increase economic benefits to consumers in Taiwan, and at the same time, placing the imported products in the leveled playing field.     

Are consumers at the base of the pyramid willing to pay for nutritious foods?

Base of the Pyramid (BoP) consumers living in the urban informal settlements of developing countries spend over 60% of their income on food, yet malnutrition and micronutrient deficiency remain widespread among these populations, pointing to the inadequacy of the foods they consume in terms of quality and quantity. In this paper we examine BoP consumers’ willingness to pay (WTP) for nutritious multi-composite porridge flour (improved flour) in the informal settlements of East Africa. The analysis is based on experimental data collected from 600 households in the informal settlements of Kampala, Uganda and Nairobi, Kenya (300 in each country) in 2016. We use Tobit regression models to analyse determinants of WTP for the improved porridge flour. Results show that both Kenyan and Ugandan BoP consumers are willing to pay a premium for the improved porridge flour. In addition, providing nutrition information about the flour, characteristics of household head, economic status of the household, and presence of young children between six and 59 months in the household, influence WTP for the safe and nutritious porridge flour. The paper concludes by providing recommendations for enhancing nutrition among poor consumers in the informal settlements of developing countries.     

Valuing New Urbanism: The Case of Kentlands

This study assesses the impact of new urbanism on single-family home prices. Specifically, we use Duany and Plater-Zyberk's traditional neighborhood development (TND) of Kentlands and surrounding conventional subdivisions to estimate the premium, if any, that single-family homeowners are willing to pay to reside in a community with new urbanist features. Using data on 2,061 single-family home transactions and several hedonic price models, the empirical evidence reveals that consumers are willing to pay a premium to locate in Kentlands.     

Sustainability labels on food products: Consumer motivation,understanding and use

This study investigates the relationship between consumer motivation, understanding and use of sustainability labels on food products (both environmental and ethical labels), which are increasingly appearing on food products. Data was collected by means of an online survey implemented in the UK, France, Germany, Spain, Sweden, and Poland, with a total sample size of 4408 respondents. Respondents expressed medium high to high levels of concern with sustainability issues at the general level, but lower levels of concern in the context of concrete food product choices. Understanding of the concept of sustainability was limited, but understanding of four selected labels (Fair Trade, Rainforest Alliance, Carbon Footprint, and Animal Welfare) was better, as some of them seem to be self-explanatory. The results indicated a low level of use, no matter whether use was measured as self-reported use of different types of information available on food labels or as use inferred from the results of a choice-based conjoint analysis. Hierarchical regression indicated that use is related to both motivation and understanding, and that both motivation, understanding and use are affected by demographic characteristics, human values as measured by the Schwartz value domains, and country differences. The results imply that sustainability labels currently do not play a major role in consumers’ food choices, and future use of these labels will depend on the extent to which consumers’ general concern about sustainability can be turned into actual behaviour.     

Health information and diet choices: Results from a cheese experiment

This study reports results from a choice experiment on semi-hard cheese from Norway. About half of the 408 participants were exposed to diet-related health information before performing either a choice or a ranking task, while a control group did not receive such information. The effects of health information on marginal willingness to pay for low-saturated-fat, low-fat and organic cheese are analyzed using rank-ordered mixed logit models. Cheese preferences are clearly affected by exposure to health information. On average, the health information group is willing to pay a price premium of 27.2% (NOK 24.5 per kg) for low-saturated-fat cheese and 14.4% (NOK 13.0 per kg) for low-fat cheese. This is respectively 1.73 and 2.89 times more than corresponding price premiums in the control group. Non-college, medium–high income, age 50–70 and female participants are more clearly affected by health information than college, low income, age 30–49 and male participants. Subjective statements on diet-health knowledge and awareness are used to discuss these findings. Our results suggest that provision of health information is likely to reduce educational differences in diet-health knowledge and thus dietary behavior. Low income participants seem to be constrained by high food prices, but not by lack of knowledge or awareness. Finally, due to lack of diet-health awareness, reaching out to young people and particularly males through health information policies seems difficult.     

Front-label health claims: when less is more

Growing global attention has been directed toward labeling the ingredients, processing methods, and health claims of food. Accompanying this attention is an interest in how consumers process or understand the information on such labels. This article examines how the length of a front-label claim influences the nutritional beliefs and evaluation of a product when used in combination with complete back-label information. The results indicate that the presence of a shorter health claim on the front of the package (in combination with a more complete claim on the back) leads a person to generate more attribute-specific thoughts about the product and fewer general evaluative thoughts compared to longer health claims. These shorter health claims also led to more favorable beliefs about the product and to a more positive image of the product. This article concludes with a discussion of the implications of the findings for policy makers, consumers and researchers.     

Consumer valuation of information about food safety achieved using biotechnology: Evidence from new potato products

This study focuses on the role of food labels and information for affecting consumers’ valuation of food safety achieved through application of biotechnological (biotech) methods. In 2002, potato products cooked to a high temperature were first reported to contain the human carcinogen acrylamide. Research discoveries using genetic engineering can substantially reduce carcinogenic-forming potential, and thereby increase food safety of potato products. Adult consumers from three distant regions of the U.S. were the subjects in lab auctions of potato products. They engaged in distinct rounds of bidding, first without packaged information and again after receiving information about the food safety risks and benefits of new biotech potato products. The study finds that willingness-to-pay (WTP) for these new potato products are not significantly different from conventional potato products under no information. However, exposure to a scientific perspective and scientific plus industry perspectives increases participants’ willingness-to-pay for the new potato products and reduces willingness-to-pay for conventional products. Exposure to the negative perspective on the new technology significantly reduces willingness-to-pay. Consumer valuation of the new potato products is affected by food labels, information, and consumer attributes. A consumer information program could be needed to gain consumer acceptance of these potato products or other foods that have been genetically modified to increase certain food safety dimensions.     

Putting their money where their mouths are: Consumer willingness to pay for multi-ingredient,processed organic food products

In response to dramatically increasing adoption in consumer markets, the National Organic Program (NOP) initiated novel labeling standards for food products in the US in 2002. This program is a particularly relevant standardization effort for multi-ingredient processed foods. Rather than a simple binary message (organic or not), gradations of organic content are now codified. No existing published study evaluates consumer willingness to pay or motivation to purchase in response to such a rich organic label. This article presents evidence of the impact of the NOP through analysis of data collected in seven central Ohio, USA grocery stores. Results suggest that consumers are willing to pay premium prices for organic foods, even those with less than 100% organic ingredients. The magnitudes of WTP premia varied significantly among consumer groups, suggesting that targeted marketing may be effective for organic merchandisers.     

Switching costs in the US seed industry: Technology adoption and welfare impacts

We evaluate the role of brand and technology switching costs in the US soybean seed industry using a unique dataset of actual seed purchases by about 28,000 farmers from 1996 to 2016. Using a random coefficients logit model of demand, we estimate brand and technology switching costs, characterize the distributions of buyers’ willingness to pay for seed brands and the glyphosate tolerance (GT) trait, and assess the implications of brand and technology switching costs for farmers’ welfare, technology adoption, firm profits, and firm market shares. We find that farmers are willing to pay large premiums for brand labels, and even larger premiums for the GT trait, although there is considerable heterogeneity in these values. Switching costs play an important role in the soybean seed industry. Eliminating these costs would significantly increase buyers’ welfare, reduce seed prices and firm profits, decrease adoption of the GT trait, and impact industry consolidation by expanding smaller firms’ market shares.     

Health claims and consumers’ behavioral intentions: The case of soy-based food

This research evaluates the impact of two soy-specific health claims (highlighting FDA approval along with scientific results and simply describing scientific results) on stated behavioral intentions toward soy-based food using a survey administered by Ipsos-Observer to a nationally representative web panel in the summer of 2007. Our research design randomly assigned respondents to a health claim. Three ordered probit models (non-soy users; infrequent soy users; regular soy users) show that non-soy users and infrequent soy users who were exposed to either FDA health claim or general health claim are significantly more likely to eat soy-based food products. FDA or general health claim, however, did not change the behavioral intentions of regular soy users. These results suggest that soy consumption status moderates the impacts of health claims on behavioral intentions. However, the impact of FDA health claim did not differ from that of general health claim, indicating that the word ‘FDA’ did not add any additional information to consumers beyond the general health claim.     

Demand for farm animal welfare and producer implications: Results from a field experiment in Michigan

This study utilizes a Becker-DeGroot-Marschak (BDM) mechanism to assess Michigan consumer demand for animal welfare practices. Results are examined in the context of changing farm production costs and producer marketing margins. We find that while consumers are willing to pay significant premiums for animal welfare standards, failing to account for the costs associated with producing the entire animal under the new system could lead to suboptimal policy that negatively affects producer welfare. Our results suggest that consumer premiums for animal welfare are product specific and that WTP estimates should not be generalized to the entire animal. We discuss policy implications of our findings and highlight the importance of considering producer costs when evaluating consumer demand for farm animal welfare practices.
