Consumer acceptance of and willingness to pay for food nanotechnology: a systematic review

The inclusion of insects as a protein source in feed production is not only related to technical, economical, and normative restrictions but is also affected by consumer acceptance. In this study, we evaluated consumers’ attitudes, intention to purchase and eat, and willingness to pay for meat obtained from a farmed duck fed with insect-based meal or a live insect diet. We conducted a survey among a sample of 565 consumers to test the effects of information about the benefits of using insects as feed on consumers’ attitudes towards animal-based products fed with insects. Providing information on the sustainability and nutritional benefits of using insects as feed increased both attitude towards and intention to purchase and eat meat products made from animals fed with insects. In the treatment group, we found a significant reduction from 21.9 to 14.0% in those who wanted to be compensated for buying a duck fed with an insect-based meal and an increase in those willing to pay the same price—from 64.9 to 72.7%. The information treatment significantly increased the intention to eat such products, suggesting that increasing consumers’ knowledge might help in reducing the fears and misconceptions around the topic of using insects as a feed source.

Observed Behaviour

Using push notifications, companies can address their smartphone app users with advertising messages. Each of these notifications can mean added value for smartphone users in terms of content, but also disruption and interruption. It is therefore important for advertisers to understand how the frequency of message delivery influences consumer acceptance. The systematic review is based on the PRISMA method and initially identifies a total of 18,725 potentially relevant scientific papers. The 17 research articles included in the qualitative synthesis show that push notifications are suitable for encouraging users to use an app and establish new habits. App usage increases with frequency, with particularly active users tolerating higher frequencies. At the same time it is also shown that too high a frequency can be perceived as disturbing and users should therefore be given the opportunity to determine the frequency with which they receive notifications. A gap in research has been identified in particular in studies that look at real observed behaviour of app users instead of behaviour reported via questionnaires and examine the interaction of frequency, content and presentation of notifications.

Underlying Structure

Fermented beverages have become a powerful player in the global beverage sector because of the increased demand for health products and their nutritional benefits to societies. This study aimed to identify consumer acceptance and willingness to pay for fermented drinks developed by MARDI. It also will evaluate the market potential of products among industry players. In this study, the data was collected using structured questionnaire and face-to-face interviews focused on the population in Peninsular Malaysia. The population's selection by stratified random sampling technique and the major survey locations included mall and hypermarket. Exploratory factor analysis (EFA) was used to discover the underlying structure of observed variables. A total of 400 respondents had participated in the study. A field survey conducted showed that 54% of respondents knew about functional foods and 55% of these are aware of functional foods based on fruits were in the market. The survey found that 30% of respondents had taken fermented drinks before, while the rest had never known this drink. Age and income have a significant influence on consumers' willingness to pay fermented drinks at a reasonable price if this product is available in the Malaysian market. Government support is needed to encourage the cultivation of indigenous fruit in Malaysia. It can be done through the provision of seed subsidies and financial resources to farmers in expanding and increasing the supply of these raw materials for the production of value-added products.

PurposeThe purpose of this paper is to establish the main factors influencing willingness to pay for health insurance and pension schemes among informal workers in low- and middle-income countries (LMICs). Historically, informal economy workers have been excluded from social protection coverage. There is a growing need, interest and policy discourse in LMICs to extend social security to informal economy workers. However, little is known about informal workers' willingness to pay (WTP) for social security services in different LMIC settings.Design/methodology/approachThe authors conducted a systematic review and searched five databases from 1987 to 2017. Included papers focused on “social security”, “social insurance”, “pension”, “informal economy”, “informal sector” and “informal workers” in LMICs. Authors conducted independent data appraisal and data extraction. A total of 1790 papers were identified. After exclusion, 34 papers were included in the analysis. Given the heterogeneous results, the authors performed a narrative synthesis to consolidate the findings of the different studies.FindingsIn total, 34 studies from 17 countries were included in the review, out of which 23 studies focused on health insurance, 7 studies on pension schemes and 4 studies on social security in general. The study showed that income and trust were associated with WTP for both health insurance and pension schemes. In addition, family size, age, education and residential area were common factors for both forms of social security. For health insurance, experience of sickness, attitude and presence of medical doctors as well as distance from the healthcare facility all played a role in determining WTP. For pension schemes, low and flexible contribution rates, benefit package, government subsidies and quality of administration of the schemes influenced enrolment and contributions.Research limitations/implicationsMore evidence is needed for WTP for pensions among informal workers.Practical implicationsThe findings show that socio-economic differences, scheme-type (health or pension) and level of trust influence WTP for health insurance or pension among informal sector workers. The review results suggest that the factors influencing WTP for health insurance and pensions interplay in a complex web of relations. More evidence is needed on WTP for pensions among informal workers.Social implicationsFurther studies are particularly needed on the interrelationship of the influences to WTP, including gender issues, access barriers and socioeconomic factors, among program design issues for social security.Originality/valueThis paper is based on a systematic review methodology and contributes to the discourse on extending social security to informal economy workers based on evidence from various countries.

Inflammatory Bowel

Abstract Background Medication costs in inflammatory bowel disease (IBD) are now the principal driver of health care costs. Cost-effective strategies to optimize and rationalize treatment are therefore necessary. Methods A systematic review until April 30, 2018, was performed to identify economic evaluations of strategies to optimize infliximab, adalimumab, and immunomodulators for the treatment of IBD in adults. A qualitative synthesis of the identified studies was performed. Results Seventy articles were identified that met the inclusion criteria. Adalimumab seems cost-effective compared with infliximab as maintenance therapy for moderate to severe Crohn’s disease (CD). Infusion costs are a significant additional treatment cost with infliximab. However, other studies found biosimilar infliximab more cost-effective than alternative biologics in fistulizing and moderate-severe luminal CD—although the latter did not reach a willingness-to-pay threshold of <$50,000. In moderate-severe ulcerative colitis, infliximab seems more cost-effective than adalimumab. Multiple tailored approaches to treatment based on objective markers of disease activity or efficacy have been shown to be cost-effective in CD, including following secondary loss of response to anti-TNF therapy for postoperative recurrence and in escalating treatment. For immunomodulator treatment, both thiopurine methyltransferase (TPMT) testing before commencing thiopurines and thiopurine metabolite testing for dose optimization seem cost-effective. Conclusion In a win-win for patients and payers, several potential avenues to achieve cost-effectiveness—but also therapeutic optimization of anti-TNF therapies—were elucidated in this review with comparatively sparse data for immunomodulators. Optimizing immunomodulator and anti-tumor necrosis factor alpha therapy to achieve objective disease control seems to be cost-effective at conventional willingness-to-pay thresholds in a number of clinical settings.

Plant factories are perceived as a sustainable agricultural production system, since they provide a cultivation environment for growing agricultural crops with less resource consumption and no pesticide use. However, as the industry and academic participants have been contributing in the development of plant factory technology, consumer acceptance for the crops cultivated from that technology remains unknown. Without consumer acceptance, all the costs spent in the research and development (RD) of plant factories cannot gain the profit. To address this deficiency, this study was aimed to: (1) investigate consumers’ attitudes, concerns and willingness to pay for the vegetables cultivated with plant factories, (2) explore the branding mode that is most effective for selling plant factory vegetables to consumers, and (3) determine the influence of consumers’ socio-demographics and vegetable purchase behavior for their willingness to pay for plant factory vegetables. With a modified strategy of multi-stage cluster sampling, a consumer survey was conducted and 390 valid questionnaires were obtained for statistical analysis. Data were analyzed with descriptive statistical analysis, analysis of variance, Duncan’s post hoc analysis, and regression analysis to meet the study objectives. The study results indicated that over half of the subjects appreciated the value of plant factory technology. However, as high as 64.4% of the subjects revealed concerns. Most of the concerns were about the issues of environmental pollution and food safety. It also showed that price played a decisive role for consumers’ purchase intentions to plant factory vegetables. Moreover, consumers were more willing to pay a higher price for the plant factory vegetables labeled with an allied brand of academic institutes and private corporations, compared with those labeled with other types of brand. Consumers who had higher income and/or consume more organic vegetables were also more willing to pay for the plant factory vegetables. The study findings help the industry participants to build up effective market strategies for selling the crops cultivated with sustainable plant factory systems.
