Do consumers view the nutrition facts panel when making healthfulness assessments of food products? Antecedents and consequences

Consumer use of the Nutrition Facts Panel (NFP) is an important topic of interest to researchers and public policymakers. Studies conducted in the United States and elsewhere find high levels of self-reported use of the NFP or its equivalent. However, data from self-reports may inflate estimated NFP use due to social desirability problems. Utilizing data from an online experiment, we examine whether consumers choose to view the NFP when assessing the nutritional properties and disease-fighting abilities of foods. We also examine the antecedents of NFP-viewing behavior and its implications for the accuracy of healthfulness judgments and the potential for overgeneralization. We conclude with a discussion of the public policy implications of our results and point to directions for future research.     

Demand for farm animal welfare and producer implications: Results from a field experiment in Michigan

This study utilizes a Becker-DeGroot-Marschak (BDM) mechanism to assess Michigan consumer demand for animal welfare practices. Results are examined in the context of changing farm production costs and producer marketing margins. We find that while consumers are willing to pay significant premiums for animal welfare standards, failing to account for the costs associated with producing the entire animal under the new system could lead to suboptimal policy that negatively affects producer welfare. Our results suggest that consumer premiums for animal welfare are product specific and that WTP estimates should not be generalized to the entire animal. We discuss policy implications of our findings and highlight the importance of considering producer costs when evaluating consumer demand for farm animal welfare practices.     

消费者意愿及地方政府行为对农户种植行为的影响机制

基于"经济人"假设和外部性原理,建立政府、农户及消费者之间的三方博弈模型,考量地方政府检查策略下的生态补贴与惩罚措施以及质量标签策略对农户种植行为的影响行为.结果表明:地方政府的生态补贴政策与农药超标罚款政策对农户的生态种植行为具有促进作用,其监管效率受上级政府检查力度以及社会舆论的影响;而实施质量标签策略可以提升农户选择生态种植行为的收益,促使农户种植行为的选择转变;消费者对质量安全的敏感性会提高其进行生态产品购买的动因,倒逼农户进行生态种植.     

Barriers and potential facilitators to the implementation of government policies on front-of-pack food labeling and restriction of unhealthy food advertising in Thailand

Thailand is experiencing an increasing burden of obesity and diet-related non-communicable diseases. The Thai government has responded by developing a number of policies to protect and promote healthy eating. In particular, in 2008, the Thai Government passed a regulation to restrict unhealthy radio and television food advertising to children (RTA). In the following year, a voluntary front-of-pack nutrition labeling policy to promote those products that had reduced their sugar, fat and/or sodium content by at least 25% (25% SFS) was passed. However, the extent of implementation of both of these policies has been poor to date. The aim of this study was to identify barriers and potential facilitators to the implementation of both the RTA and 25% SFS policies. Semi-structured interviews were conducted with 28 participants holding senior positions in government, industry and civil society organizations closely involved in the implementation of these policies. The interview data were analyzed using the thematic framework analysis approach. The major barriers to policy implementation perceived by participants were a lack of a monitoring and evaluation system, a lack of organization knowledge regarding skills required for implementation, poor governance system, lack of funding and resources, lack of effective multi-sectoral platforms, influence of the food industry, lack of clear policy content, organizational culture and structure, and changes in policy priorities. Factors that potentially facilitated implementation of these policies, as identified by participants, were policy being compatible to implementer’s context, individual support from government officials, good financial management mechanisms, inter-organization networks, and personal motivation to implementing policy. The successful implementation of policies to create healthy food environments in Thailand will likely require attention towards improving the capacity and authority of government agencies, infrastructure to support multi-sectoral platforms and inter-organizational networks, and adequate resources.     

How Should Food Safety Certification Be Financed?

An analytical framework where consumers are imperfectly informed about the safety of products is used to investigate the welfare effects of a public certification system. Several certification fees under alternative structures of certification cost are analyzed. By maintaining competition among numerous sellers, voluntary certification financed by a per-unit fee is efficient (and sufficient) to signal product safety. However, mandatory certification linked with a fixed user fee may be necessary if a seller wields monopoly power. Further, certification by a single, private agency results in a distorted fee.     

Moving up in taste: Enhanced projected taste and freshness of moving food products

Can implied motion enhance consumer judgment of food freshness and taste? Freshness plays an important role in determining anticipated taste. Different perceptual cues may influence judgments of freshness. While some cues such as coloring and bruising play an obvious role, the authors argue that cues that on face value appear unrelated to freshness may also influence judgments of freshness. Specifically, the authors argue that humans have learned to relate movement to food freshness, and that this leads perceived motion to generate enhanced judgments of freshness, and, consequently, projected taste. This proposition is demonstrated in four studies. The studies show that the inclusion of implied motion in food pictures leads to elevated judgments of freshness and projected taste.     

A comparative analysis of hedonic models of nutrition information and health claims on food products: An application to soup products

Over time, the quality of data on food purchases and label information has improved such that hedonic analyses to determine the implicit prices of product attributes can be conducted using more detailed data than in the past. With the availability of more extensive data, it is important to understand the characteristics of the data and implications of using different data sources on results of analyses. The purpose of this study was twofold: (1) compare results between two sources of label information and (2) develop a better understanding of the effects of product claims and nutrition information on the value of products to consumers. Trans fat claims, organic claims, private label, package size, and several nutrients were found to influence implicit prices for soup products, and the results between the two data sources are comparable.     

Death from drowning: defining a new challenge for child survival in Bangladesh

The study focuses on children less than 5 years old and explores the epidemiological profile and correlates of drowning as a challenge to child survival in Bangladesh. Two data sources from Bangladesh, a cohort of 8,070 children followed for 2 years in a rural area and a nation-wide survey conducted in 1996–97 have been used. In addition, a systematic review of the literature has been conducted spanning the past two decades for analysis of drowning in children. Seventy drowning deaths were reported in the cohort and 726 deaths were reported in the national survey. Verbal autopsy and semi-structured interviews were conducted on all deaths. Drowning accounted for 43% of deaths in the cohort and 20% of deaths in 1–4-year-old children in the national survey. Most drowning deaths were in 12–23 month old children from falling into ditches and ponds. Communities provided valuable insights on possible interventions to reduce deaths due to drowning. Drowning is a newly recognized challenge for Bangladesh. Considerable research and programmatic work is required to understand the nature of the problem and develop appropriate interventions. This paper calls on aid agencies to create opportunities for drowning research and action in their work plans for the country.     

User preference mining based on fine-grained sentiment analysis

User preference mining is an application of data mining that attracts increasing attention. Although most of the existing user preference mining methods achieved significant performance improvement, the sentiment tendencies of users were seldom considered. This paper proposes fine-grained sentiment analysis for preference mining. The powerful feature representation capabilities of deep neural networks have significantly improved the performance of fine-grained sentiment analysis. But two main challenges remain when using deep neural network models: incomplete user feature extraction and insufficient interaction. In response, a pre-training language model is employed to encode user features to fully explore potential interests of users, a linguistic knowledge model is introduced to assist the encoding, a multi-scale convolution neural network is adopted to capture text features at different scales and fully utilize the text information, and the fine-grained sentiment analysis task is modeled as a sequence labeling problem to explore the sentiment polarity of user evaluation. Experiments on a user review data set are used to verify the new approach. Experimental results of precision, recall rate and F1-value show that the proposed approach performs better, and is more effective than baseline models. For example, the F1-value is increased by 4.27% compared to the best performing baseline model. Findings have important implications for research and practice.     

International review of ecodesign programs for products and lessons learned for China

ABSTRACT

Since the 1980s, ecodesign has emerged as a new guiding principle for integrating environmental aspects into product design and development, with the aim of reducing adverse environmental life-cycle impacts. For China, the concept of ecodesign is becoming important in advancing Chinese industrial development while mitigating the rise in national energy consumption and emissions. We reviewed 28 existing ecodesign labels and supporting programs adopted globally to identify lessons learned and best practices for the development of potential ecodesign labeling programs in China. We find that systematic framework and process and inclusion of various stakeholders in developing criteria, certification requirements and supporting policies in the form of green procurement, small local pilot subsidies, and active outreach and communication are key success factors of international programs. Based on international experiences and by leveraging existing Chinese frameworks for labeling and policies, China has an opportunity to lead in developing broader environmental criteria for a new ecodesign labeling program.
