Consumer awareness and willingness to pay for safety of street foods in developing countries: a review

Street food vending is still popular in developing countries despite the giant stride recorded in the areas of food processing and global food supply in the last century. Its contribution to the socio‐economic development of the countries is evidenced by the volume of trade involved and provision of employment for significant portion of rural and urban populace. However, there has been persistent global concern on the risks of street food to the health of consumers because of the attitudes of practitioners throughout the chain. This review summarizes the findings of studies on awareness and perceptions of street food consumers to the hazards involved in street food, and their willingness to pay (WTP) premium for safety intervention. The major limitation to WTP is the extra cost that could result from the implementation of reports of WTP studies which could disenfranchise those consumers that may not be able to afford the premium. This review, therefore, recommends the formulation and enforcement of appropriate public policies that would cover the entire chain of street food vending for the safety of everybody along the chain and the protection of the health of the consumers.     

Using discrete choice experiments to estimate willingness-to-pay intervals

Willingness-to-pay has always been conceptualized as a point estimate, frequently as the price that makes the consumer indifferent between buying and not buying the product. In contrast, this article estimates willingness-to-pay (WTP) as an interval based on discrete choice experiments and a scale-adjusted latent-class model. The middle value of this interval corresponds to the traditional WTP point estimate and depends on the deterministic utility; the range of the interval depends on price sensitivity and the utility??s error variance (scale). With this conceptualization of WTP, we propose a new measure, the attractiveness index, which serves to identify attractive consumers by combining knowledge about their price sensitivities and error variances. An empirical study demonstrates that the attractiveness index identifies the most attractive consumers, who do not necessarily have the largest WTP point estimates. Furthermore, consumers with comparable preferences can differ in their purchase probability by an average of 16%, as reflected in differences in their WTP intervals, which yields implications for more customized target marketing.     

Factors Influencing Consumers’ Willingness to Pay for Organic Fruits and Vegetables: Empirical Evidence from a Consumer Survey in India

Numerous consumers confronted with increasing environmental problems, food safety issues, and augmentative health problems increasingly desire to have healthier and more natural foods grown in an eco-friendly manner. Hitherto organic foods only partly benefit from this increasing market environment, and their market share stays rather low despite high growth rates. This article aims to investigate consumers’ willingness to pay (WTP) for organic fruits and vegetables and relevant factors affecting consumers WTP. The contingent valuation method was selected to estimate WTP. Empirical data was drawn from a 250-consumer survey conducted in Bangalore during February 2013. A binomial logistic regression model was applied to obtain the value of WTP and determine the factors influencing it. The results indicated that about 90% of the consumers were willing to pay a premium price ranging between 5% to more than 100% in order to acquire better-quality fruits and vegetables; factors such as family income, size of the family, gender, and other opinion variables such as chemical residue in conventional foods, trust on retailers, taste, and environmental concerns significantly influence consumers’ WTP. More than 87% of the consumers indicated that high price, lack of availability, narrow range, and irregular supply are the major barriers for them to buy these products. The results provide useful evidence to pertinent governmental agencies in terms of assisting in the design of policies for the promotion of organic food production and marketing and reaching the target public. Furthermore, firms involved in the organic foods business may also see benefits when drawing information in order to calibrate marketing strategies.     

The Impact of Warnings,Disclaimers, and Product Experience on Consumers’ Perceptions of Dietary Supplements

Two experiments explored the impact of disclosures (warning and disclaimer) and product experience (heavy, light, and nonusers) on consumers’ perceptions of dietary supplements. In general, the government‐mandated disclaimer did not impact consumers’ beliefs about either the efficacy or the safety of dietary supplements; for most consumers, the disclaimer is unlikely to achieve its intended results. However, when product experience was examined, analyses show that heavy product users responded differently to the disclosures than did light product users and nonusers. Results point to the importance of understanding the influence of individual differences on the interpretation of product disclosures by specific consumer segments.     

Consumer willingness to pay for sustainable apparel: the influence of labelling for fibre origin and production methods

This study of value‐based labelling for apparel products examined consumer willingness to pay (WTP) for three credence attributes of fibre: origin, type and production method. Experimental auctions were conducted with student subjects in Texas and used socks made from cotton and polylactic acid (PLA), a fibre manufactured from corn. The bid results of two rounds were compared. The first round was conducted without information about the credence attributes of the socks. The second round included varying levels of three types of attributes: fibre origin (imported, US and Texas), fibre type (cotton and corn) and production method [conventional, organic and non‐genetically modified (GM)]. Tobit regression analysis was performed using the attributes and subject demographics to determine consumer WTP for the various attribute levels and to profile consumers with interest in the attributes. In terms of origin, results show that participants were willing to pay a premium for socks with fibres produced in Texas, but not for those produced in the US. Fibre type mattered, with participants requiring a discount once they learned that socks were made with PLA fibre. The greatest premium ($1.86) was placed on socks labelled as organic, slightly more than the premium for socks labelled as non‐GM. The results also indicate that women were less willing to pay for US fibres than men, and Hispanics were less willing to pay for organic or non‐GM fibre production. A key finding of this study is that consumers value information about the local origin of fibres. The premium for organic fibres is not unexpected, given the success of the organic apparel market, but the premium on non‐GM fibres suggests that sustainable production systems that are not organic may be successful if they emphasize other attributes such as local or non‐GM.     

Employing a Dichotomous Choice Model to Assess Willingness to Pay (WTP) for Organically Produced Products

Abstract

This study employs a dichotomous choice model to identify the socio-economic characteristics and attitudes that influence consumers' willingness to pay (WTP) a premium for organically produced products (OPP). Considering consumers' growing interest in quality and safety of food, the study attempts to identify consumers level of awareness on OPP, the intention to buy OPP and the WTP a higher price for OPP. Results highlight consumers awareness and intention, revealing useful information for the development of OPP market. The estimated maximum WTP indicates that consumers are willing to pay a substantial extra price to purchase OPP. Finally, WTP seems to be affected by certain consumer attitudes and socio-economic factors.     

Perception of Risks and Preferences for Locally Grown Produce: A Marketing System Approach

In recent years, the “buy local” movement has escalated in popularity. This trend is redefining how value along the food chain is shared between producers, retailers, and consumers. A theoretical model was developed and used to evaluate how consumers formulate preferences for locally grown attributes, with an emphasis on consumers’ perceptions of food safety risk. Linkages between locally grown produce attributes, perceived macro outcomes, and value allocation to consumers are then examined using random utility discrete choice models. While results were mixed depending on frequency of purchasing locally grown produce, they do indicate that consumer preferences are driven by perceived food safety risk and other macro outcomes. For example, consumers who frequently purchase locally grown produce perceive these products to be environmentally friendly and to improve their quality of life.     

Effects on Nutrition Label Regulation on Consumer Choice

The U.S. government initiated food labeling reform in 1989, which culminated with the Nutrition Labeling and Education Act (NLEA) of 1990, emphasizing the provision of improved nutrition information on most food products. The goal of such labeling reform has been to provide consistent, readable, understandable and usable food labels that enable consumers to make more healthful food choices. This paper examines the theoretical impact of the new regulations on consumer food choice behavior. The paper first discusses the use and impact of food labels by/on consumers, and uses a choice model to desribe the effects of these new labels on consumer food choice decisions. In particular, the research focuses on two important food attributes, and the presence of information of these attributes through the new nutrition labels, which may influence consumer purchase behavior.     

Consumers’ attitudes,trust and willingness to pay for food information

Market failure can be corrected using different regulatory approaches ranging from high to low intervention. Recently, classic regulations have been criticized as costly and economically irrational, and thus, policy makers are giving more consideration to soft regulatory techniques such as information remedies. However, despite the plethora of food information conveyed by different media there appears to be a lack of studies exploring how consumers evaluate this information and how trust towards publishers influence their choices for food information. In order to fill such a gap, this study investigates questions related to topics that are more relevant to consumers, who should disseminate trustful food information, and how communication should be conveyed and segmented. Primary data were collected both through qualitative (in‐depth interviews and focus groups) and quantitative research (web and mail surveys). Attitudes, willingness to pay (WTP) for food information and trust towards public and private sources conveying information through a new food magazine were assessed using both multivariate statistical methods and econometric analysis. The study shows that consumer attitudes towards food information topics can be summarized along three cognitive‐affective dimensions: the agro‐food system, enjoyment and wellness. Information related to health risks caused by nutritional disorders and food safety issues caused by bacteria and chemical substances is the most important for about 90% of respondents. Food information related to regulations and traditions is also considered important for more than two‐thirds of respondents, whereas information about food production and processing techniques, lifestyle and food fads are considered less important by the majority of respondents. Trust towards food information disseminated by public bodies is higher than that observed for private bodies. This behaviour directly affects WTP for food information provided by public and private publishers when markets are shocked by a food safety incident. WTP for consumer association (€1.80) and the European Food Safety Authority (€1.30) are higher than WTP for the independent and food industry publishers that cluster around zero euro. Furthermore, trust towards the type of publisher also plays a key role in food information market segmentation together with socio‐demographic and economic variables such as gender, age, presence of children and income. These findings invite policy makers to reflect on the possibility of using information remedies conveyed using trusted sources of information to specific segments of consumers as an interesting soft alternative to the classic way of regulating modern food markets.

Malleability of taste perception: biasing effects of rating scale format on taste recognition,product evaluation,and willingness to pay

Product-related cues, such as brand or price, can influence consumers’ taste perception. Going beyond this observation, we examine the extent to which a stimulus-extrinsic factor, such as the format of the measurement tool on which consumers describe attributes of a taste sample, influences concurrent taste perception, and in turn, later taste recognition, overall product evaluation, and willingness to pay (WTP). The results of two experiments show that rating scale format (i) influences consumers’ concurrent impression of a taste sample, (ii) systematically biases later identification of the sample in a taste recognition test, and (iii) affects overall product evaluation and WTP. However, scale format (iv) does not influence ratings and downstream judgments when consumers are highly knowledgeable in the product domain. These findings demonstrate that the experience of taste is fleeting and not well represented in memory, and that like other subjective experiences, taste needs to be reconstructed based on accessible cues.     

Assess the impact of subjective norms of consumers' behaviour in the Greek olive oil market

The objective of the research was to highlight the role that socio-economic and spatial attributes of consumers – households exert on their choices regarding not only the supply modes but also the price they are willing to pay for different categories of olive oil. Regarding WTP for different olive oil labels, consumers are willing to pay premiums only for olive oils being processed by either private companies or cooperatives, with the latter to gain 34% of them in case they would decide to change the olive oil they usually purchase. The most important consumer profile is the young educated consumer one.     

The Effect of Information on Willingness to Pay for Canned Tuna Fish with Different Corporate Social Responsibility (CSR) Certification: A Pilot Study

The objective of this study was to assess the role of information in consumers' willingness to pay (WTP) for food products with corporate social responsibility (CSR) certification. The item used for the experimental design was canned tuna fish, a product on the market that is already exhibiting various kinds of certification related to social and environmental attributes. Two different kinds of certifications were examined, namely Friend of the Sea, which involves environmental aspects, and SA8000, related to workers' rights and more general social attributes. We implemented experimental auctions, taking into account three information treatments. The initial findings show that the WTP for both CSR labels is higher than the WTP for tuna fish without any CSR certification. Nevertheless, the information provided on CSR certification did not change consumers' WTP among the certification schemes. Our findings could also serve to fine‐tune marketing strategies to consumer preferences and determine which CSR activities are worth undertaking.     

Effects of social responsibility labelling and brand on willingness to pay for apparel

This study examined changes in consumer willingness to pay (WTP) for apparel products as labour‐related information and brand were added. Tobit analysis of auction bids from 121 university students for t‐shirts showed men, Hispanics and consumers who believe in social responsibility and fair trade had significantly higher WTP once labour‐related labelling was added. The amount and complexity of information did not matter, leaving substantial leeway to companies in crafting their message. Adding brand significantly increased WTP for two better‐known brands while not changing WTP for the social responsibility messages. Results suggested brands can benefit from stressing social responsibility‐related attributes of products.     

Estimating the effects of nutrition label use on Canadian consumer diet‐health concerns using propensity score matching

The overarching goal of nutrition labelling is to transform intrinsic credence attributes into searchable cues, which would enable consumers to make informed food choices at lower search costs. This study estimates the impact of nutrition label usage on Canadian consumers’ (n = 8,114) perceived diet‐health concerns using alternative propensity score matching (PSM) techniques. We apply a series of tests and sensitivity analyses to overcome issues of endogeneity and selection bias frequently found in studies of diet‐health behaviour and to validate the impact of exposure to nutrition facts labels for users vs. non‐users. Our results support the notion that consumer uncertainty and related food‐health concerns are linked to their information behaviour, but not in straightforward manner. Dominant subjective food attributes, such as taste, convenience and affordability, may in fact outweigh the benefits of information about healthier, alternative food choices. In order to change dietary health behaviour, food manufacturer and policy makers alike need to adopt communication instruments that better account for differences in preferences, shopping habits and overall usage patterns of nutrition labelling information.     

Quality-Labeled Vegetable Consumption in Malaysia: Factors Affecting Attitude and Purchase Intent

The rising rate of foodborne diseases has caused not just consumers but also food producers to become increasingly concerned about food safety. As a result, the government of Malaysia, together with relevant bodies, have introduced quality-assurance agencies to certify food products that are produced, processed, and handled with methods that are acknowledged by the certification agencies as clean and safe for consumption. This study aims to identify the factors influencing consumer purchasing behavior toward quality-labeled vegetables. A survey was conducted using a self-administered questionnaire and distributed randomly to consumers in public places in the Klang Valley. Four hundred and sixteen respondents were approached. The results indicate that most of the respondents are aware of food quality labels. Using factor analysis, four latent factors that influence consumer attitude toward quality-labeled vegetables were identified, and the importance of quality attributes (sensory, health, safety, and social attributes) in shaping those attitudes was also shown.     

Development of functional food with the participation of the consumer. Motivators for consumption of functional products

The purpose of the study was (1) to define the most important characteristics of functional food affecting purchasing decisions; (2) diagnose the importance of the healthful properties of functional food; (3) identify preferences for carriers (base product) and the importance of the functional components essential in the choice of functional products; and (4) get to know the motives by which consumers are guided when purchasing functional food. The data were collected through direct interview (n = 200). The research tool was a questionnaire divided into four sections. The first one included quality attributes. The second one included healthful properties, functional components and carriers. The third one concerned the motives for purchasing functional food and included the consequences and values. In the fourth section the participants were asked about gender, age and education. The results of this study allowed determining the most important attributes of functional food products. Among quality attributes the most important are safe food, natural product and healthy product. The most important organoleptic attributes include nice taste. Very important attributes of packaging and labelling include expiry date and information on the healthful properties of the product. The most important healthful properties are associated with the attributes (1) strengthens the immune system; (2) reduces the risk of certain cancers; (3) reduces the risk of cardiovascular diseases; (4) helps maintain the correct body weight; (5) strengthens eyesight; (6) improves memory; and (7) improves physical condition. The functional components concern mainly vitamins and minerals, omega‐3 fatty acids and dietary fibre. As the best base products, consideration was given to bread, dairy products, cereal products, mixtures of fruits and vegetables and meat products. In the motivation system there were distinguished functional consequences that included improvement of health, needs of the organism, and healthy eating and psychological consequences such as conscious choice and health promotion. The most important autotelic values include good health and long life, health safety, inner harmony, self‐respect and self‐confidence. The means to achieve these goals are responsibility for health and care for health. The study provides bases for a better understanding of the consumer's needs and optimization of activities related to the development and consumption of functional food. The results of this study may provide valuable support for actions connected with the promotion and marketing of food products.     

Information search behaviour and its determinants: the case of ethical attributes of organic food

Daily decisions on food purchase are known to be undertaken using limited information search. However, when confronted with ‘ethical’ products, consumers often become more involved, and this results in a more extensive search for information. This research focuses on the information search behaviour of European consumers with regard to ethical attributes like animal welfare or environmental aspects of organic food by means of an Information Display Matrix. Row‐wise information search by product characteristics (attributes) was widely preferred over information search by product alternatives (column‐wise). Therefore, information (e.g. in the Internet) should increasingly be provided by attributes. The majority of consumers use simplifying and selective search strategies when looking for information on organic food with additional ethical attributes. Consumers tend to start information search in the top, left hand corner and move towards the bottom, right hand corner. Thus, principal attributes should be placed in the upper left corner and be followed by the next most important and so on when presenting information on an array of different products. Our results show that information search patterns of consumers depend on socio‐demographic characteristics like gender and age and, to a lesser extent, also on attitudes regarding environmental or social aspects of food production. Thus, marketers, particularly those using the Internet, should revise their systems of information provision and focus increasingly on consumers' needs.     

An exploration of the influence of food labels on South African consumers' purchasing behaviour

New labelling legislation in South Africa is expected to help consumers sustain a healthy lifestyle through the food choices they make. This study was undertaken to explore a sample of South African consumers' reasons for reading labels and the influence of food labels on their purchasing behaviour. The study was conducted using focus group discussions held with label reading consumers in Potchefstroom in the North West Province of South Africa. Findings suggested that these participants read food labels to assess the nutritional value, personal benefits, health attributes and product quality. Various purchasing influences were also identified, suggesting that consumers are in some cases motivated by food labels to purchase a product, or may be unresponsive to the label or indifferent by being aware of the information but not reluctant to buy a product that does not indicate essential information. Several indirect consideration factors such as situational factors (e.g. family), extrinsic (e.g. price) and intrinsic (e.g. taste) may contribute to the purchasing behaviour of some consumers. These findings are useful to propose a perceptual model of the way in which food labels influence purchasing behaviour of a sample of South African consumers and explain the role of food labels in the purchasing decision of label‐reading consumers. This information is especially significant for new packaging and labelling initiatives as it highlights the reasons why label‐reading South African consumers read label information.     

Socio‐demographic basic factors of German customers as predictors for sustainable consumerism regarding foodstuffs and meat products

An important step in promoting sustainable purchase behaviour is to explore the understanding of responsible consumerism from the consumers’ point of view. For this purpose, a study among 1040 German consumers was carried out using a two‐pronged approach. First, open‐ended questions were used to explore the characteristics of sustainable food consumption in general as well as the willingness and meaningfulness of a low‐meat diet from the consumers’ point of view. After that the interactive structure behind the term was studied using a quantitative empirical method. As standard of evaluation the four underlying socio‐demographic factors gender, age, wealth and education are used. Apart from the consumers’ financial situation, the applied statistics show significant correlations of the propensity for sustainable consumerism to each of the above factors. Women, middle‐aged and well‐educated consumers show a greater tendency to purchase environmentally and socially sustainable products. Accordingly, the suitability of socio‐demographic factors is confirmed in this study. The open‐ended questions fathom what attributes consumers connect with sustainable food consumption, in particularly with regard to the consumption of meat. It is clear that attributes that affect consumers directly and attributes which can be directly influenced by their actions are better perceived by the consumer. Altruistic factors or abstract aspects of food consumption (e.g. climate protection) are generally of less significance. Conversely, factors which concern the value added chain, like for example, origin and processing, have priority. To conclude, the findings enable the identification of the variables determining the sustainability construct. This allows policy makers to develop customized incentive systems. Similarly, private sector stakeholders are enabled to adapt marketing activities and their product mix to consumer demands.     

Consumer Willingness to Pay for Local Designations: Brand Effects and Heterogeneity at the Retail Level

This study examines consumer willingness to pay (WTP) for packaged ice cream with local, private label, and national brands at the retail level. Data were collected through in-person surveys conducted at retail grocery outlets in Utah in 2012. Study results suggest that shoppers are willing to pay significantly more for the national and local brands over the retailer’s private label brand. In fact, the local brand with the state-sponsored designation (Utah’s Own) had a WTP equal to that of the national brand. The use of local designations or labels is important as shoppers were not willing to pay a premium for the local brands in absence of the locally produced or state-sponsored designation label. Additionally, consumer WTP for different brands and the degree of response to local designations varies substantially by consumer attributes. These differences suggest that locally designated products do not compete directly with private label products in the market. This study provides clear evidence of the value of state-sponsored designations, as well as locally produced labeling for food products marketed in a traditional retail setting.
