Changes in demographic and socioeconomic characteristics have contributed to an increase in away-from-home food consumption. Although consumers are increasingly demanding higher quality food, unbalanced nutrition intakes and health issues such as obesity remain prominent predicaments. This paper investigates the relationship between the frequency of having Food Away From Home (FAFH), balanced dietary intakes, and obesity (controlling for covariates) among Korean adults aged 19 to 64. Whether there exists a linear relationship between the number of having FAFH and health outcome is investigated and the optimal number of having FAFH that leads to the best health outcome is identified in the study. The results suggest that Food Away From Home generally increases deviations of dietary intakes from the reference intakes and high-frequency FAFH consumers have an elevated chance of being obese (36.22%). However, having FAFH 1–7 times per week is associated with decreased body mass index (BMI) and a lower chance of being obese in comparison to the outcomes of having food at home. The optimal level of consuming FAFH is identified to be 5–7 times per week in terms of BMI and obesity. However, consuming no FAFH is suggested to be the best in terms of balanced nutrition intake.
As income is rising and urbanization progressing, the consumption of meat and dairy products is increasing, especially in developing countries. However, increasing livestock production leads to challenges that need to be addressed, such as yielding environmental pollution and causing climate change. Due to these circumstances, the importance of sustainable livestock farming has been highlighted in order to effectively utilize natural resources and to protect the environment. We analyzed consumers’ preference and willingness to pay for milk, one of the representative dairy products, which was produced in a sustainable way. Among the various attributes of milk, marginal willingness to pay for “performing sustainability” through mountainous farming was estimated to be the biggest. The willingness to pay was revealed to be higher for the consumer group with a high awareness of sustainable farming than the consumer group with low awareness. The empirical results in this study suggest that it is important to consider the economic feasibility of dairy farming by forming a consensus with consumers through publicity and changing the production pattern to promote sustainability.
This paper elicits consumers' preferences associated with attributes of a very popular food product in Asia: red ginseng concentrate. The results of a choice experiment suggest that an asymmetric information problem can cause consumers' preferences and valuation for red ginseng concentrate to be significantly influenced by objective information about the product's attributes. The results imply that while objective information can result in differential changes in valuation for different product attributes, it can increase consumers' willingness to pay for red ginseng concentrate. The paper also discuss important policy and marketing implications from the results of the study.
Abstract:Coupled with green house effects, the urban heat island is occurring more frequently, and thus is becoming a serious social problem. In order to elicit policy implications, the current study assesses the economic values on the heat island-mitigating functions of urban forest through choice experiments. The analytical results suggest that metropolitan city residents' utility can be increased by raising the size of life zone forests which is comprised of street trees, parks in residential regions, and small forests in school zones. The derived marginal willingness to pay for the life zone forests suggest that the respondents are willing to pay $56.68-76.59 for every increase of the urban forest by 1 m 2 .
The eco-friendly certification system is designed to ensure safe agricultural products to consumers while minimizing environmental pollution. However, despite its advantages, it is not widely adopted due to a possible decrease of farmers’ income. In order to provide implication for activating the eco-friendly certification system, this paper examines the attributes of green tea which affect consumers’ preferences and estimates consumers’ willingness to pay (WTP) for the eco-friendly certification in China. A choice experiment survey is employed for data collection, and the random utility model is used to estimate the preference for the certification and quality of green tea. The attribute that yields the highest marginal WTP turns out to be the organic certification for which WTP is $115.9/250g higher than for no certification. Also, the analytical results indicate that the group with high trust is willing to pay up to $214.6/250g more for green tea with organic certification compared to the one with no certification. The empirical results suggest that it is important to build the consumers’ awareness and trust toward the certification to activate the eco-friendly certification system.
