Determinants of Consumer Attitudes and Purchase Intentions With Regard to Genetically Modified Food – Results of a Cross-National Survey

Previous research has shown consumers to be highly sceptical towards genetic modification in food production. So far, however, little research has tried to explain how consumers form attitudes and make decisions with regard to genetically modified foods. The paper presents the results of a survey which was carried out in Denmark, Germany, Italy, and the United Kingdom to investigate the formation of consumer attitudes towards genetic modification in food production and of purchase decisions with regard to genetically modified yoghurt and beer. Altogether, 2031 consumers were interviewed in the four countries.Results show that attitude formation and decision-making are more comparable among Danish, German, and British consumers than with Italian consumers. Italian consumers turned out to be significantly less negative towards genetic modification in foods than particularly Danish and German consumers. Across countries, the attitude towards genetic modification in food production was deeply embedded in more general attitudes held by the consumers, in particular attitude towards nature and attitude towards technology. These general attitudes were found to influence perceived risks and benefits of the technology. Purchase decisions with regard to the two product examples were almost exclusively determined by attitudes towards purchasing the products. These were, in turn, significantly influenced by the overall attitude towards genetic modification in food production through their effects on beliefs held by consumers regarding the quality and trustworthiness of the products.The results suggest that attitudes towards genetically modified foods are quite strong, despite their lack of basis in actual product experience. Likewise, the strong relation of product-specific attitudes to the attitude towards using genetic modification in food production suggests that at present consumers reject the technology overall rather than evaluate products on a case-by-case basis. This situation may, however, be changed by a possible increased availability of genetically modified food products on the consumer market.     

Product attributes and consumer acceptance of nutritionally enhanced genetically modified foods

Using data from a national survey, this study analyses US consumers’ acceptance of genetically modified foods that provide additional nutritional benefits. Using an ordered probit model, this study examines the relation between the willingness to consume genetically modified foods and consumers’ economic, demographic and value attributes. Empirical results suggest that despite having some reservations, especially about the use of biotechnology in animals, American consumers are not decidedly opposed to food biotechnology. Consumers’ economic and demographic variables are only weakly related to their acceptance of food biotechnology, especially when technology involves plant‐to‐plant DNA transfer. However, public trust and confidence in various private and public institutions are significantly related to their acceptance of food biotechnology. Overall, consumer acceptance of bioengineered foods is driven primarily by public perceptions of risks, benefits and safety of these food products.     

Understanding the drivers of organic foods purchasing of millennials: Evidence from Brazil and Spain

This paper examines the antecedents of millennials' organic food purchasing. A conceptual framework, based on product characteristics, and consumers' concerns and consciousness, is proposed. Data collection was conducted through a survey in two culturally and socioeconomically distinct countries (Brazil vs. Spain) to increase the robustness and generalizability of the results. The results show that product characteristics and consumer concerns improve millennials’ health consciousness and increase their social consciousness, which, in turn, increase their willingness to pay a price premium and their purchase frequency of organic foods. The findings show that the proposed model has high validity, with only one significant difference between the two countries. Theoretical contributions and managerial implications are discussed.     

Young Chinese and Functional Foods for Mobility Health: Perceptions of Importance,Trust, and Willingness to Purchase and Pay a Premium

Consumers’ desire to enhance diet and health has become a driver for the development of functional food products. China, with one of the largest markets in the world, offers huge potential for these foods. In the context of functional foods, specifically related to mobility health, this study aimed to understand Chinese consumers’ perceptions of the importance of these foods, trust, and willingness to purchase and pay a premium for such foods. A mixed-methodological approach using both focus groups and a survey was used to collect data from Chinese living in New Zealand. Findings show Chinese consumers place a high level of importance on their mobility health. Level of importance increased when asked about the believed importance of this area later in life. Key factors influencing Chinese consumers’ willingness to purchase functional foods were also identified: the carrier/nutrient combination; trust in the product’s country of origin and in the various institutions that may be involved in the production of functional food products; trust in both the product brand and how it is advertised; health motivation; and price. The study offers the food industry insights into the development and marketing of mobility-related functional foods targeted to this market.     

Quest for the eco‐apparel market: a study of mothers' willingness to purchase organic cotton clothing for their children

The purpose of this study was to examine what consumer characteristics are related to willingness to purchase and selection of children's organic cotton clothing (OCC). A survey was conducted on mothers of pre‐schoolers to collect data on mothers' environmental characteristics, involvement with OCC and children's clothing, children's clothing purchasing behaviour and willingness to purchase OCC. A buying scenario experiment was used to examine whether price and other product characteristics influenced the participants' selection of OCC. It was found that a mother's environmental concerns, environmental purchasing behaviour and recycling behaviour significantly affected their involvement in OCC, which further significantly determined mother's willingness to purchase OCC. However, mothers were not willing to pay a premium for purchasing children's OCC. A majority (59.5%) of the mothers who selected OCC in the buying scenario indicated fabric softness was the main reason for their selection. Preparing environmental education materials for consumers and producing OCC with high quality and good performance would help improve the acceptance of OCC in the market.     

Genetically modified foods: Consumer awareness,opinions and attitudes in selected EU countries

The dynamic development of biotechnology in recent years has raised serious public concerns about the possible risks arising from genetically modified organisms (GMOs). The aim of this study was to investigate consumer opinions regarding genetically modified (GM) foods. The research also aimed at verifying the differences in the attitudes of respondents from two, relatively culturally diverse research sites. To obtain empirical data a face‐to‐face survey was conducted in 2015. It covered a total of 976 randomly selected individuals. The study was performed in the capital of the United Kingdom—London and the Polish capital—Warsaw. The results of the study show that almost half of the respondents were familiar with the GMO concept. According to the respondents, the greatest benefits arising from the genetic modification are: enhanced shelf‐life of food and crops' resistance to extreme climatic conditions. The main disadvantages were: unpredictable consequences of deoxyribonucleic acid (DNA) modification, production of species‐specific toxins and food allergenicity. Over two thirds of people surveyed support the idea of the obligatory labeling of GM foods. The information presented on food packaging should primarily include potential contraindications to the consumption, indication that food was produced using transgenic sources and a warning about potential allergenicity. An almost equal number of respondents showed intention for purchasing GM food products, an intention to act otherwise, or was not decided. As many as 27.7% of survey participants showed negative attitudes toward GM foods, whereas only 19.8% predominantly positive. It is worth noticing that, with only one exception, no statistically significant differences were observed between the opinions of Polish and British respondents.     

The mediation effects of consumers’ need recognition and pre-purchase evaluation in consumers’ decision-making on purchasing safe street food: The case in Nakhon Si Thammarat,Thailand

Nakhon Si Thammarat province is one of the largest cities in Thailand and offers various types of street foods in the city. However, the number of street vendors that pass food safety certification is very low. Nevertheless, there are many consumers who still purchase street food because of their lifestyle who are exposed to food safety risks. Therefore, this research aims to evaluate how consumers make their decisions about the safety of the street food. This study investigates the importance of the need recognition and pre-purchase evaluation stages in consumers’ decision-making in relation to their purchasing of safe street food. The results from the structural equation modeling analysis found that, at 95%, the confidential need recognition would act as a partial mediator between consumers’ motivation → pre-purchase evaluation on purchasing safe food and consumers’ food safety knowledge → pre-purchase evaluation. In turn, pre-purchase evaluation would act as a full mediator between consumers’ motivation and safe street food purchasing. The findings signify that the stages of need recognition and pre-purchase evaluation in the decision-making process are important in order to reduce consumers' food risk while purchasing street food. Therefore, encouraging consumers to recognize the importance of purchasing safe food and convincing them to be concerned when selecting food is necessary to prevent consumers from unsafe food consumption.     

Winning ugly: Profit maximizing marketing strategies for ugly foods

Ugly foods meet nutritional and safety benchmarks but deviate from cosmetic and size standards. The marketability of ugly food is a major factor that frustrates field-level food rescue efforts. We investigate opportunities to promote ugly foods in a way that converts uniform negative preferences towards ugly food to more diverse and horizontally differentiated preferences where some consumers prefer ugly food to standard offerings and pay a premium. We conduct an online discrete choice experiment and find a portfolio of marketing strategies that significantly enhance respondent willingness to pay for ugly carrots. Dual messages that simultaneously (1) link the purchase of ugly food to reductions in food waste and (2) suggest ugly food is natural and authentic significantly improve willingness to pay. We also find respondents tolerate some level of mixing of ugly with standard carrots. We find the most profitable strategy is to form bunches that include 40% ugly and 60% standard carrots and to sell the bunches with green leaves attached at farmers markets where consumers receive dual marketing messages. Profit simulations confirm that, in the absence of such marketing strategies, farmers rationally create waste by discontinuing harvest when the percentage of remaining carrots that are ugly is high.     

Structural Equation Modeling of Consumer Purchase Intention Toward Synthetic Functional Foods

Functional foods are gaining greater popularity around the world. They are not just a new category of food products marketed for their health benefits, but their competitive market has made consumers become more favorable toward firms that are involved in this industry. The public is increasingly concerned about health and food-related risks. They tend to make decisions on food consumption, food storage, and food preparation on a more ideal perspective based on health and safety. Therefore, the objective of this study is to determine the factors and intention of Malaysian consumers to purchase synthetic functional foods. Structural equation modeling is used to accomplish the objectives of this study with the feedback received from the 2,004 households who were interviewed through a structural questionnaire. The results show that the most influential factors influencing consumer purchasing intention toward synthetic functional foods are perceived benefits followed by attitude and subjective norms.     

Classifying Consumer Purchasing Decision for Imported Ready-to-Eat Foods in China Using Comparative Models

This study aims to identify factors influencing consumer purchasing decision for imported ready-to-eat foods by investigating marketing factors and lifestyles in China (Beijing and Shanghai) using comparative models. Consumers in each city showed different specific lifestyles but shared consumption culture and traditions in common. Regarding lifestyles, consumers who usually buy instant food products face long commutes to work and prefer less cooking time were more likely to buy imported ready-to-eat foods. Findings suggest that product development, labelling with quality guarantees, packaging design, the production process, and multichannels are the prominent factors persuading Chinese consumers to purchase imported ready-to-eat products.     

Food or Medicine?

Abstract

Functional foods offer consumers a range of products that contain modified ingredients to treat specific diseases. The value of this product category has grown considerably since its introduction over a decade ago. This paper reports on qualitative research conducted into the choice criteria used for functional foods. It then compares these to the categories outlined in Khan's food choice model (1981) in order to determine whether functional foods should be treated as a food choice purchase. The findings of this research show that functional food can be treated as a food purchase because most of the choice influences found can be categorised into Khan's conceptualisation. However, additions and redefinitions are suggested. A separate category for family influence was found, as was the requirement to redefine “nutrition” within the model to accommodate the curative benefits of functional foods.     

Analysis of Snack Food Purchasing and Consumption Behavior

This exploratory research examines the purchasing and consumption behavior of snack food consumers. A structured questionnaire and intercept interviews were used to collect quantitative data from respondents inside supermarket stores. For marketers, a key contribution of this study is the importance of the price attribute and certain product claims. Sugar and total fat were found to be the most important nutritional factors that consumers consider when making a purchase decision, but it was also found that only around one half of all consumers actually read product labels when purchasing snack foods. Matters of particular concern that are highlighted by this study are that one third of consumers do not consider their snacking behavior to be healthy, and one quarter of consumers choose to snack in secret. This study addressed a number of gaps in current knowledge by identifying the snack food products that are most frequently consumed, the reasons for consuming snacks, whether consumers read snack food product labels, the importance of various attributes and product claims, whether consumers regard their snacking behavior to be healthy, and whether they snack in secret.     

Gender differences in consumers’ acceptance of genetically modified foods

Research has shown that women are less accepting of genetically engineered products than men. We expect two mechanisms to be at work here. First, in consumer behaviour theory, more knowledge is assumed to lead to more acceptance. We assumed that for genetically engineered foods, this general principle does not apply since long‐term consequences are not known yet. The well‐informed consumer is likely to be comparatively more concerned with this lack of knowledge. We call this the information paradox. Theory on the topic is relatively recent. The results of this study will help to distinguish consumer behaviour with regard to new types of food as compared with traditional foods. Second, we assumed that there is a gender factor included in attitudes toward foods. In general, women still plan food and household purchases. A tentative attitude and an accompanying reluctance toward food innovation are adopted when buying food for children. We call this the gender paradox. In this exploratory study we use data from the Eurobarometer. Eurobarometer surveys have been executed since 1973 by the European Commission among the adult population of European Union member countries (n > 10 000), monitoring the evolution of public opinion. Analysis of these surveys shows that gender differences exist in the acceptance of genetically modified (GM) foods in Europe. Women tend to be less accepting toward genetically modified foods. This supports our gender hypothesis. However, no evidence was found to support the assumed information paradox. It seems that knowledge leads to acceptance, also of GM foods, but more so for men than for women.     

Influencing consumer purchase likelihood of organic food

Organic food is a fast‐growing niche market in the US. Information in the marketplace tends to promote organic by describing either the potential benefits from organic methods (positive framing) or the potential negative consequences of conventional agriculture (negative framing). For this research, a survey was designed to test the effect of positive and negative framing on the self‐reported change in purchase likelihood of organic food. Respondents were asked to directly evaluate whether the information in the survey made them more or less likely to purchase organic food, or if there was no change. Over 40% of the respondents reported greater likelihood of purchasing organic as a result of the survey information, and less than 4% said they would be less likely to buy it. Tobit regression results revealed that positive framing and perceived risk from conventional agricultural methods increased the influence of the survey. African‐Americans and those with more prior knowledge of organic methods reported less influence from the survey. Overall, information and knowledge variables had more effect on the impact of the survey than demographic variables.     

Billion Dollar Baby: Local Foods and U.S. Grocery

This study reviews consumer purchasing of locally produced foods in retail grocery stores. A U.S. sample of 590 consumers was drawn via an online survey, with structural equation modeling used to assess hypothesized relationships of attitude, subjective norms, perceived behavioral control, intention to purchase, extent of purchase, and the moderating effects of shopping channel type. Results from structural model testing suggested that all hypothesized relationships except that of purchase intention and extent of purchase were found to be significant, with group differences existing between supercenters/warehouses and farmers’ market shopping channels. Implications and future research directions are provided.     

Adolescents’ attitudes towards organic food: a survey of 15‐ to 16‐year old school children

Adolescents are the consumers of tomorrow; therefore policies aimed at increasing organic food consumption should address the needs of this group. To discover their attitudes towards organic food and their knowledge of the subject, a survey among almost 700 school children aged 15–16 years was conducted. Four main groups of questions were used: adolescents’ knowledge of organic food, attitudes, whether they bought organic food and the perceived influences they exerted on the buying patterns of their parents. From the survey it can be concluded that adolescents’ attitudes towards organic food are positive, but their knowledge of and their willingness to buy it are low. Campaigns aimed at encouraging the purchasing of organic food targeted at adolescents should particularly emphasize those characteristics of organic foods that they can relate to their interests and ethical preferences, for example, animal welfare and environmental considerations.
