    <p>To address the aging farming population, farmers’ markets have implemented a pickup service for collecting agricultural products. However, previous research has shown that it is unprofitable. Moreover, it is unclear whether the pickup service was designed optimally in the previous study. Given the aging farming population, the spatial distribution of pickup service users is expected to become sparse in the future, and the demand for pickup services is anticipated to expand spatially. In this regard, designing an economically sustainable and efficient pickup route with multiple pickup points is necessary.</p><p>In this study, first, we design a farmers’ market pickup model using a Vehicle Routing Problem (VRP). Previous research on VRP did not take the loading and unloading times into account. However, in the farmers’ market pickup service, inspecting agricultural products and loading and unloading them from the truck is necessary. The driver also has to transmit information to the users of this service. To reflect such reality, we establish a pickup time constraint equation that considers truck running times and loading and unloading times.</p><p>Second, we demonstrate that the time limit in the constraint equation is valid for adjusting the designed model for planning pickup services in the mountainous areas of Fukuoka Prefecture.</p><p>Finally, we examine the economic viability of the case study. After verifying the balance between total pickup costs and usage fees, we conclude that operating the pickup service on Saturdays, Sundays, and holidays is economically viable.</p>

  • Consumer acceptance and valuation of quality-improved food products derived by genome editing technology. A case study of rice in Vietnam

    Unlike genetic modification, genome editing (GE) technologies can be used to yield transgene-free outcomes, which is an important aspect in promoting consumer acceptance of GE foods. In addition, with the advent of the clustered regularly interspaced short palindromic repeats/Cas9 (CRISPR/Cas9) system, which is known to be exceptional among genome editing tools, GE has numerous potential applications in plant breeding technology to create diverse desirable traits, especially consumer-targeted traits such as improved product quality and nutrition. It is expected that the GE foods market will overtake that of genetically modified (GM) foods. Although few GE products have been introduced to the market, some studies have already evaluated consumer acceptance and valuation of GE foods in comparison with GM and conventional foods. However, these studies mainly focused on traits relevant to cultivation efficiency and ignored consumer preferences for desirable traits. Further, it has been shown that consumers evaluate GE foods somewhat higher than GM foods; yet, as observed for GM foods, consumers expect a discounted price for GE foods. GE application for consumer-targeted traits could, however, have a potentially positive effect on consumer acceptance. This study was conducted to evaluate consumer acceptance and valuation of quality-improved consumer-targeted GE products. We defined the determinants and estimated the willingness to pay a price premium for GE rice compared to GM and conventional rice by using the double-bounded contingent valuation method under different information treatments. The survey was conducted in Vietnam, where consumers have not been exposed to information regarding GE via social media that could lead to a biased perspective. This context is ideal for investigating the effect of information provision during the introductory stage of GE products to the market. Our main findings suggest that consumers will widely accept quality-improved GE foods targeted at consumer preferences, as well as the positive influence of in-depth information provision on potential consumer acceptance.

    This paper focuses on the determinants of genome-edited foods by identifying trends in the application of CRISPR/Cas9 to major crops and reviewing consumer and regulatory studies on both GE and genetically modified (GM) foods. Findings show that GE crops have not been only targeted in input traits like GM crops, but also strengthened production ability in harsh environmental conditions, improving product quality and enhancement nutrition. Especially, these consumer-targeted traits pursued in GE applications could rise consumer acceptance. Consumer-targeted traits coupled with transgene-free crops has created a more balanced risk-benefit perception and given momentum to GE foods production. Nevertheless, the public has failed to distinguish bio-technologies, and regulators are treating GM and GE foods alike. Thus, it is vital to increase knowledge, communication and policy orientation. Policymakers should carefully assess novel bio-technologies and apply an appropriate regulatory approach to GE foods to promote the agricultural system and food safety.

    Purpose: Expanding the market share of safe food through a modern retail system has faced a lot of difficulties in Vietnam. Thus, a further understanding of consumer behaviour and loyalty towards such food is essential for food retailers. This study aims at exploring segments of consumer loyalty and its influential factors towards safe food brands in the country. Design/methodology/approach: Based on a sample of 250 consumers buying safe food in Hanoi city in February 2019, two-step cluster and multinomial logistic regression analyses were applied. Findings: The results show that four segments of brand loyalty were formed from the interaction between attitudinal and behavioural loyalty as the framework of Dick and Basu (1994), namely, true loyalty, spurious loyalty, latent loyalty and disloyalty. Notably, over 60% of the consumers were in latent loyalty and spurious loyalty, indicating variety-seeking behaviour, multi-brand loyalty or low recognition of the brand. Consumer satisfaction was the most vital motivating consumers to higher loyalty levels. Additionally, brand trust and brand familiarity played significant roles in developing true brand loyalty. An attractive selling store and friendly staff were also important in enhancing brand loyalty. Originality/value: This study is one of the first to elicit consumer loyalty and identify factors driving the loyalty towards brands of safe food in a developing country like Vietnam.

  • Implicit and Explicit Attitudes toward Foods Derived from Genome Editing and Genetic Modification Technologies under Different Information Treatments

    Nguyen, TH; Ben Taieb, S; Moritaka, M; Fukuda, S

    Genome editing technologies represent a potential revolution in plant breeding methods. However, there is a limitation in understanding the consumers’ attitudes toward foods derived from this novel technology. Especially, the lack of knowledge and confusion in differentiating with genetically modified (GM) products could potentially restrict further development of genome-edited (GE) foods. Therefore, a survey of 407 Vietnamese consumers was conducted to analyze the implicit and explicit attitudes toward GE foods compared to GM foods under different information treatments. The implicit association test (IAT) was used for implicit evaluation, and semantic differential scales were used for explicit evaluation. As our important results, under the context of condensed information, the implicit measure shows a high correlation between attitudes toward GE and GM foods. This result is one of the initial pieces of evidence that has been shown about the relationship among consumers’ attitudes toward GE and GM foods. And as our result has been pointed out that providing in-depth information help to reduce the correlation between attitudes toward GE and GM foods. This evidence is important to suggest effective risk-benefits communication to help reduce negative attitudes toward GE food and increase consumers’ acceptance.

    The olive oil market in Japan has been growing at a fast pace since the late 90s. Indeed, the olive oil is now one of the most consumed oils in Japan. However, this growth in popularity remains unexplained. Indeed, our knowledge on the Japanese consumer of olive oil is pretty limited. In this research, we studied the effect of the health consciousness on the consumption of olive oil. To do so, a hierarchical Bayesian model, with a tobit base, was employed to analyze scanner panel data. These data were combined with attitudinal data that were collected through a survey. The results showed that consumers with a high level of health consciousness do indeed buy more olive oil than those who are not health conscious. Additionally, the health status of consumers had a significant effect on consumption, indeed, consumers suffering from diabetes buy smaller amounts of olive oil.

    The objective of this study was to assess the effects of health consciousness on consumption of olive oil in Japan. To do so, an experimental auction was conducted where participants were divided into several groups ranging from 6 to 9 people. The process of the experiment started with an explanation on how the auction works followed by a practice round to get the participants to fully understand the auction mechanism. once the practice round was over, the participants took a quiz to assess their understanding of the auction and finally the actual auctions were conducted. Inbetween the 2 rounds, the participants were given information on the health benefits of the olive oil. The results of this research showed that participants with better understanding of the benefits of olive oil had a higher willingness to pay for it. This suggests that even relatively young people are becoming more health conscious, wanting to prevent diseases in the future.
