Consumer Perception of Genetically Modified Food: Empirical Evidence From India

Although the advent of genetically modified (GM) foods changed the agricultural scenario in developed countries, existing research confirms that consumer perception about the consumption of the same is often distorted. GM foods entered the Indian market amid widespread controversies and criticisms. There exists a host of studies that tried to establish the factors that shape favorable consumer perception toward GM foods indeed, but evidence from developing countries like India is still missing. The article undertakes an exploratory investigation of the factors that shape consumer perception about the consumption of GM foods in India and subsequently confirms the same with the aid of a measurement model. The study provides important implications for managers in directing efforts toward influencing consumer perception and instigating positive attitudes toward GM foods so that the benefits of their use can be extended to the masses in relatively nascent markets.     

Consumer Benefits of Labels and Bans on GM Foods—Choice Experiments with Swedish Consumers

The European Union has been relatively cautious about using biotechnology in food production. A label regime combined with the right of individual member states to ban introduction of new genetically modified (GM) strains means that GM food products in effect are banned in many countries. We show how it is possible to empirically test whether a ban can be motivated by reference to potential negative externalities. This is followed up by results from a choice experiment. We cannot reject the hypothesis of equal WTP for a ban and a labeling scheme.     

Consumers’ Response to Genetically Modified Ingredients in Processed Food in an Emerging Economy

Genetically modified (GM) foods are available in many countries including post–Soviet Union countries. However, empirical evidence on consumer acceptance for this region is scarce. In this study, we investigate consumers’ willingness to purchase a processed food containing GM ingredients. For this purpose, a consumer survey was conducted in 2015 in Tajikistan. In many aspects, our results confirm previous empirical findings showing that women are more skeptical toward GM food and a higher level of respondents’ education and the presence of minors in households are negatively correlated with their willingness to purchase a processed food containing GM ingredients. Moreover, a higher risk perception of GM food is negatively associated with the probability to purchase and consume such foods. However, our results indicate that risk perceptions of GM food seem to be relatively low in comparison to other studies with 41.5% of Tajik respondents connecting no risks with GM food. This result is surprising given the existing knowledge about post–Soviet Union consumers who are usually assumed to reject GM food due to their strong focus on naturalness.

Labeling Context and Reference Point Effects in Models of Food Attribute Demand

There is considerable interest in the effect of labels on food product demand. Labeling statements may convey new information about attributes and place consumers in different choice contexts; consumers' assessment of information in labels may be affected by reference points. We examine labeling context relating to genetically modified (GM) food as a factor in the stochastic component of a random utility model and assess reference points over a set of observable characteristics of consumers. We find that labeling context effects are present, although relatively small, while reference dependence is a very important factor that varies over observable characteristics of the sampled consumers.     

Risk Perceptions, Risk Preference, and Acceptance of Risky Food

Consumers' risk preferences are often overlooked in studies of consumer demand for risky food. We find that risk preferences elicited through context-less lottery choices are significantly related to consumers' stated preferences for genetically modified (GM) food. These results suggest risk preferences elicited in the laboratory are not artificial in the sense that they appear to be related to the same risk preferences that govern other individual decisions such as food choice. Consistent with theoretical expectations, risk perceptions and risk preferences were found to be significant determinants of acceptance of GM food, which has important implications for explaining consumer behavior.     

Consumer trust, risk and food safety: A review

Consumers' attitudes to trust and risk are key issues in food safety research and attention needs to be focused on clearly defining a framework for analysing consumer behaviour in these terms. In order to achieve this, a detailed review of the recent literature surrounding risk, trust and the relationship between the two must be conducted. This paper aims to collate the current social sciences literature in the fields of food safety, trust and risk. It provides an insight into the economic and other modelling procedures available to measure consumers' attitudes to risk and trust in food safety and specifically notes the need for future research to concentrate on examining risk and trust as inter-related variables rather than two distinct, mutually exclusive concepts. A framework is proposed which it is hoped will assist in devising more effective research to support risk communication to consumers.
