Welfare and Market Impacts of Food Safety Measures in China: Results from Urban Consumers' Valuation of Product Attributes

This study provides an economics assessment of various food safety measures in China. A choice experiment approach is used to elicit Chinese consumer preferences for various food safety attributes using data from a 2008 urban consumer survey. An alternative welfare calculation is used to model aggregate market impacts of select food safety measures. Our results show that the largest welfare gains are found in the current government-run certification program. The implementation of a third-party certification system, a traceability network and a product label would generate significant value and would help reduce current system inefficiencies in China. This study builds on previous research and provides an alternative approach for calculating consumer valuation of safety and quality attributes that can be used to estimate aggregate economic and welfare impacts.

Consumer Associations with the “All Natural” Food Label

ABSTRACT “All natural” food labels have become increasingly popular in recent decades. Labels may communicate to consumers a level of food quality above that of unlabeled products. In April 2011, a nationally representative survey was conducted asking respondents to estimate the likelihood that they will increase purchasing in response to an “all natural” label on food products. The sample totaled 1,000 respondents, with 49% being male and 35% between the ages of 45 and 64. Demographic information includes gender, age, income, region, and education. Ordered logit models were used to estimate the likelihood of changes in purchasing based on the “all natural” label. This stated that intended behavior change was evaluated using the ordered logit estimates for nine products: beef, pork, poultry, ice cream, yogurt, cheese, milk, soft dairy products, and bread and bakery products. For all products, being male and having too little information at grocery stores decreased the likelihood of purchase. Conversely, those respondents, who associate the “all natural” label with no preservatives, perceived such products to have improved taste, improved nutritional value, and improved food safety increased the likelihood of purchase.

Consumer perceptions of egg-laying hen housing systems

The egg industry has transitioned, or is in the process of transitioning, from conventional cages to alternative hen housing systems in response to legal changes in many states across the United States (US). However, consumers find it is increasingly difficult to understand the details behind those labels and specific attributes conveyed. There are multiple hen housing options with a wide range of costs and impacts on hens, workers, and the environment. This research furthers the understanding of US public perceptions and attitudes related to hen housing systems and corresponding animal welfare, worker, economic, and environmental effects. Results reveal that the US public perceives cage-free aviaries as achieving essentially the same positive impact on hen health and stress, hen behavior, and environmental impact as free-range systems when compared to conventional cage systems. The information provided can assist industry, marketing, and policy decisions with respect to hen housing.

Eastern gray squirrels are consistent shoppers of seed traits: insights from discrete choice experiments

Seeds of many hardwood trees are dispersed by scatter-hoarding rodents, and this process is often mediated by the traits of seeds. Although numerous studies have linked seed traits to seed preference by rodents, little is known about how rodents forage for seeds when multiple desirable and undesirable seed traits are available simultaneously. Here, we adopt a novel method of designing choice experiments to study how eastern gray squirrels (Sciurus carolinensis) select for 6 traits (caloric value, protein content, tannin concentration, kernel mass, dormancy period and toughness of shell) among seeds. From n = 426 seed-pair presentations, we found that squirrels preferentially consumed seeds with short dormancy or tougher shells, and preferentially cached seeds with larger kernel mass, tougher shells and higher tannin concentrations. By incorporating random effects, we found that squirrels exhibited consistent preferences for seed traits, which is likely due to the fitness consequences associated with maintaining cached resources. Furthermore, we found that squirrels were willing to trade between multiple traits when caching seeds, which likely results in more seed species being cached in the fall. Ultimately, our approach allowed us to compute the relative values of different seed traits to squirrels, despite covariance among studied traits across seed species. In addition, by investigating how squirrels trade among different seed traits, important insights can be gleaned into behavioral mechanisms underlying seed caching (and, thus, seed survival) dynamics as well as evolutionary strategies adopted by plants to attract seed dispersers. We describe how discrete choice experiments can be used to study resource selection in other ecological systems.

Exploring preferences beyond the (cereal) box: ready-to-eat breakfast cereal buying behaviors

Ready-to-eat breakfast cereals vary widely in terms of nutrition and price. The diversity in cereal offerings makes it ideal for the study of preferences for individual nutrients and the potential impact that providing nutritional information may have on consumer purchasing behavior. Using a survey of 1,265 Midwestern residents, a random parameters logit model was employed to estimate the willingness to pay for nutritional elements of ready-to-eat breakfast cereal. Household demographic data, including household food security status, were collected. Agricultural and food businesses may seek to provide product information, including nutritional information, to their customers. In addition, national and local policies may seek to empower consumers’ decision making through education. Nutritional information may not have the intended impact of influencing healthier choices. Responses from those shown educational material on nutrition were tested and found not different from respondents not shown the information.

Self-reported healthcare provider utilization across United States Midwestern households

Understanding the relationships between health care provider usage and demographics of patients is necessary for the development of educational materials, outreach information, and programs targeting individuals who may benefit from services. This analysis identified relationships between health care provider usage and individuals demographics. A sample of Midwestern U.S. respondents (nu202f=u202f1265) was obtained through the use of an online survey distributed February 12–26, 2016 and was targeted to be representative of the population of the Midwestern states sampled in terms of sex, age, income, and state of residence. Specific factors identified as significant in contributing to provider usage (in the past five years) differed across the eleven provider types studied. In the most commonly used practitioners (the general or primary physician), relationships between provider usage and age, income, health insurance coverage status, and having children in the household were identified. Furthermore, significant (and positive) correlations were identified between the usage of various practitioners; reporting the use of one type of practitioner studied was correlated positively with reporting the use of another type of health care provider studied in this analysis. This analysis provides insight into the relationships between health care provider usage and demographics of individuals, which can aid in the development of educational materials, outreach programs, and policy development.

Perceptions of Agriculture and Food Corporate Social Responsibility

ABSTRACT An online survey of 1,201 U.S. residents was conducted in April 2015 to better understand individuals’ perceptions of prominent areas of corporate social responsibility (CSR) in the food supply chain. Demographic and household consumption information, including supermarket patronage, was collected. Each respondent completed best–worst tasks for CSR areas designed to elicit their relative importance of CSR areas. Overall, health and safety were perceived as the most important CSR area, and environment was prioritized second. Indicating gender as female and/or reporting age over 65 was positively correlated with the relative importance placed on health and safety, but negatively correlated with the size of preference share for nearly all other CSR areas investigated. Membership in the younger age categories was positively correlated with the size of the preference shares devoted to procurement, labor, fair trade, and biotechnology.

US Residents’ Perceptions of Dog Welfare Needs and Canine Welfare Information Sources

ABSTRACT The extent to which welfare needs of breeding dogs are met in commercial dog-breeding kennels is a potential point of controversy. This analysis sought to understand US residents’ perceptions and priorities related to dog welfare : by investigating (a) perceptions of breeding-dog welfare needs and (b) perceptions of various nonhuman animal welfare information sources. Using best/worst-choice experiments conducted in an online survey, respondents’ choices for most and least important breeding-dog welfare needs (n = 508) and most/least trusted canine welfare information sources (n = 508) were analyzed. The survey sample was targeted to be representative of the US population in terms of gender, age, region of residence, income, and education. The largest preference shares (relatively most important) for breeding-dog welfare needs were for “availability of food and water” (39.2%) and health/veterinary care (18.1%). The largest preference shares (relatively most trusted sources) for welfare information were American Society for the Prevention of Cruelty to Animals, a veterinarian, and American Veterinary Medical Association, with 25.1%, 16.4%, and 14.1% shares, respectively.

The intersection of food insecure populations in the Midwest U.S. and rates of chronic health conditions

BackgroundFood insecurity is the state of having insufficient access to adequate food in order to maintain a healthy lifestyle due to limited economic resources. This study expands upon the annual survey conducted by the USDA ERS, while providing evidence that additional factors, notably, medical or health-related issues play vital roles in the relationship between households and food security.MethodsThe data for this study were generated by surveying Midwestern residents. The sample of respondents was targeted to be representative of the Midwest in terms of sex, age, and income and was completed by 1265 respondents. The survey included the CPS Food Security Supplement to assess the food security of respondents. All respondents were asked the 10 household focused food security questions and respondents who indicated having children were asked the additional 8 child focused questions. Additionally, respondents were asked demographic, food security, and health status questions.ResultsOf the sample, 25% were considered food insecure. Being male, middle aged, having children, having household diabetes, having a household eating disorder, and having household depression/anxiety are significant determinants of decreased food security.ConclusionsEstablishing clear relationships between health and food can help to inform legislation. This analysis suggests the inclusion of chronic illness and health information to improve metrics and inform food security legislation.

When is genetic modification socially acceptable? When used to advance human health through avenues other than food

Given the potential for genetic modification (GM) to impact human health, via food and health mechanisms, a greater understanding of the social acceptance of GM is necessary to facilitate improved health outcomes. This analysis sought to quantify U.S. residents’ acceptance of GM across five potential uses (grain production, fruit or vegetable production, livestock production, human medicine, and human health, i.e. disease vector control) and provides an in-depth analysis of a timely case study–the Zika virus (ZIKV). The two categories with the highest levels of acceptance for GM use were human medicine (62% acceptance) and human health (68% acceptance); the proportions agreeing with the use of GM for these two categories were statistically different from all other categories. Acceptance of GM in food uses revealed 44% of the sample accepted the use of GM in livestock production while grain production and fruit and vegetable production showed similar levels of agreement with 49% and 48% of responses, respectively. Two variables were significant in all five models predicting GM acceptance; namely, being male and GM awareness. Being male was significant and positive for all models; respondents who reported being male were more likely (than those who reported female) to agree with all five of the uses of GM studied. Those who were reportedly aware of GM mosquito technology were also more likely to agree with all uses of GM technology investigated. The potential relationship between awareness of GM technology uses and acceptance of other uses could help inform rates of acceptance of new technologies by various population segments.
