This paper intends to analyze and re-examine the actual effectiveness, types of necessary activities, and impact of export restrictions of grains and oilseeds, which arise as a result of political and economic decision-making. The analyzed data are official reports prepared by the U.S. International Trade Commission, the General Accounting Office (GAO), and the investigation report of the Congressional Research Service of the United States. All these reports cover five export restrictions during the period of 1973 to 1980.What is understood from these reports is to enforce export restriction required excessive time, labor, and financial costs, and made losing the credibility as a stable supplier of the international grain market as well as giving advantages to other competitors such as Brazil, Argentina, and Canada. These are all well-known facts to date. Based on these experiences, the United States has not issued export restrictions for grains and oilseeds for the past three decades even during the grain crisis in 2008. There are some findings, however, about who actually suffered damages from the embargoes among farmers, exporters, and the governments. The paper also classifies the basic merits and demerits of export restrictions in different levels of stakeholders.

This research examines how providing Japanese consumers with fair trade information affects their willingness to pay (WTP) for fair trade bananas. We estimated the WTP before and after providing information with 86 young consumers in their 20s through an online survey by a conjoint analysis. The results show that providing information increased WTP by those who have understood fair trade or have been interested in the poor without information. Especially, the information about the benefits of fair trade is more effective than the information about the disadvantages of non-fair trade.

In this study, we examined the differences in food preparation efforts and their causes. We used two-step online survey data comprising 50,000 samples with 726 samples in each step. We clustered the data by the degree of effort, obtaining four clusters of individuals—those who enjoyed preparing and expressed concern for every meal, enjoyed preparing dinner, sought to minimize their efforts, and preferred quick meals in all situations. We then measured the food values using the best–worst scaling method and found that attitude differences toward food preparation were well characterized by differences in food values and socioeconomic conditions.

We investigated the impact of food additives on the price of fish paste products by using a hedonic price approach. For our research, food additives include preservatives, coloring materials, sweeteners, pH adjusters, polysaccharide thickeners, calcined shell calcium, trehalose, sorbitol, xylose, and calcium carbonate. As a result of the analysis, we found that products using preservatives have a statistically significantly lower price than others, and the other food additives do not have statistically significant price effects. The result suggests that preservatives contribute toward keeping the cost of goods from increasing during distribution and marketing and enable a reduction in the price of fish paste products. Using preservatives reduces the financial burden of consumers and contributes toward consumers getting substantive benefits.

The purpose of this study is to analyze, based on evidence, factors preventing the elderly from maintaining a healthy diet by using a revised food access indicator that takes food availability in stores into account. The area being studied is A City, a regional city in the northern Kanto region of Japan. The dependent variable in the study was dietary diversity score, which is a measure of the risk of adverse health effect caused by deterioration of diet. Multilevel analysis was used for the analysis of factors to allow individual level factors and group level factors to be analyzed independently.Regarding the individual level factors, results of the analysis suggest that FDs problems are present in areas with reduced food access, reduced social capital, or both, which supports the previous finding of FDs study groups. Among the group level factors, the presence of a store within a close distance of 500m most strongly affected the diet of the elderly. However, when a supermarket with nearly 100% food availability was located about 400m away or further, the condition for raising dietary diversity score from low to high was not met. In contrast, when the data was analyzed by assuming the shopping range to be 2km each way, the availability of a store as fully stocked as a supermarket within about 1.3km met the condition for raising dietary diversity score from low to high.

Recently, with the social requirement, traceability systems come into use for recognition of thehistory or origin of the food product. However, there remain important problems: what and how muchinformation should be supplied to consumers. Some people argue that the information should beoffered as much and detailed as possible. Others suggest that because a deluge of information is notdesirable, we should sort out or summarize the information and then provide to consumers.In this paper, for inquiring the desirable quantity of information with traceability systems, weanalyze the consumers' ability of processing information by using discrete choice models. Throughthe experiment by increasing the quantity of information, two interesting results are obtained. First, we identify the point at which the effect of information overload occurs. The result shows thatinformation entropy indexes are lowest at 6 attributes and become higher at more than 6 attributes.These imply that information overload effect appears around 6 attributes. Second, “knowledge” and“product involvement” are found to be dep ressant factors of information overload. People who havehigh knowledge or high involvement have relatively low entropy index.From these findings, we can argue that to provide too much information to consumers isproblematic because it makes consumers confuse. To avoid this, we should select what is importantinformation for them. It is also important to offer an appropriate education and enlightenment inorder to heighten their knowledge and involvement.

This is a food environment intervention study, aiming at improving the diet of hospital workers. The intervention was conducted at a convenient store in a hospital in Tokyo. The intervention included availability, accessibility, information and incentive. We used nudge tactics to increase the effect. To evaluate the intervention, we used the point of sales data and examined the response of the staff. Total sales and sales of healthy items significantly increased. The intervention was well-accepted by the staff. It suggests that using nudges to improve the food environment at a convenient store in a hospital can increase sales.

In North America, we can find various attempts to change local food systems by considering the viewpoints of multiple stakeholders. In particular, the concepts of food policy (Tim Lang) and citizen's engagement are key. In this paper, I will describe how these ideas have been discussed in North America by referring to various practical attempts to solve issues of local food systems, such as food policy councils, urban food policy, food charters, and so on. After describing the details of these activities and implications to food access issues, I argue that we need to consider the multi-functionality of food in urban society, and that this idea encourages us to develop a more coordinated relationship between food systems and urban planning in local contexts. Understanding the multi-functionality of food leads us to reconsider the nature of food from the viewpoint of “food as commons” rather than food as commodity.

With the advance of genetic modification (GM) technology, there has been a trend towards trade in genetic information. However, considering genetic information as vital information, there are questions over whether it is appropriate to treat it as a tradable good. In other words, such trade raises ethical questions regarding the control and utilization of genetic information.To study these ethical questions, it is first necessary to clarify the problems relating to property of genetic information. This article studies a case involving seeds for agricultural use, and will critically examine the relevant legal system and previous arguments from the viewpoint of the justification of private property. This study has resulted in indicating three new points.First, property of genetic information has become an issue due to the use of GM technology in plant breeding. The genetic information is considered to be a tradable good separate from the seed itself, leading to a situation in which a seed = matter + genetic information. From an analysis of the legal system, it is clear that genetic information can be considered private property.Second, an analysis of prior discussion has shown that the notion of genetic information as private property is regarded as a self-evident truth in economic studies of the issue. This has resulted in avoidance of discussion on any values other than economic efficiency and the initial allocation of goods.Third, by critically reviewing previous discussion from a viewpoint of regarding genetic information as vital information, it became clear that genetic information has unique points when compared with other economic goods.In conclusion, the justification of property rights of genetic information should be reexamined from the viewpoint of the fundamental principles of property rights and the uniqueness of genetic information.

In Taiwan in recent years, the sales volume of organic agricultural products and foods has been increasing year by year, and the organic market is growing, against the backdrop of heightened awareness of safety, security and health. Recent research is revealing the actual situation of building an organic food chain in Taiwan, but the actual situation of the efforts of co-ops is unclear. The Homemakers Union Consumers Co-op, which is a nationwide organization, was established for the purpose of creating a safe environment for obtaining safe food. In addition, this co-op aims to realize a sustainable society by building a food chain of organic agricultural products and food. This article reveals that the collaborative product development process plays an important role.

This study clarifies the actual conditions of organic food products and business development in food manufacturers to understand the actual conditions of the organic food business in Taiwan. In particular, we examine the case of SauceCo Co., Ltd. Results of the analysis reveal that SauceCo has expanded the organic food category through innovation and marketing. SauceCo’s organic food and management development are not limited to the innovation process. Marketing, especially the opportunity for direct communication such as the NCHU Organic Farmers Market, is also used to develop and improve organic foods.

The purpose of this study was to clarify the actual status of game meat consumption and consumption intentions in urban restaurants, and to examine measures to increase consumption. The implications of the analysis are as follows. 1.Game meat served at casual restaurants tend to be a low evaluation. Cooking techniques and menu development will be important. 2. Potential consumers are consumers with a strong desire to explore food and a strong sense of meat-loving, but at present, concerns about sanitation are having a negative impact on the expansion of consumption. Therefore, providing information from restaurants to consumers about safety between is important.

This study uses the Random Parameter Logit model and examines the determinants of consumers’ willingness-to-pay (WTP) using Structural Equation Modeling to estimate WTP concerning the purchase of animal welfare livestock products. The study results show that consumers generally positively perceive animal welfare-certified pork. The results also suggest the importance of educating people, strengthening their attitudes that purchasing animal welfare-certified pork can effectively solve animal welfare issues, and raising awareness among consumers that their actions can contribute to animal welfare issues. Raising social awareness to evaluate ethical consumption positively would also be helpful.

Genome editing is being applied in various fields of life sciences, such as medicine, agriculture, food and energy. Regarding the regulatory status of genome editing in Japan, policies are being issued by the Ministry of Health, Labor and Welfare and the Ministry of the Environment, and applications to the fields of agriculture and food are being widely considered. However, there has hardly been any explicit discussion on the differences between applications for plants and animals. We argue there are several points that should be taken into account. In this paper, we clarify the unique regulatory issues that separate genome edited animals from plants, in particular, safety assessment, consumer perception, and animal welfare.

The Japanese diet is known for its ideal balance of the three macronutrients, namely protein, fat, and carbohydrates. Dietary statistics indicate that over time, in Japan, these macronutrient ratios have been maintained since the mid-1970s in close agreement with favorable macronutrient ratio intake standards, set by the Japanese Ministry of Health, Labour and Welfare. The ideal ratio is principally achieved by reducing carbohydrates, while increasing fats. However, in recent years, this macronutrient ratio appears to depart from ideal ranges, due to over-westernization of the Japanese diet. To investigate the extent of this phenomenon, we analyzed a time series data set for ingested nutrition by using cointegration techniques to identify long-run, stable relationships among the three macronutrients, between 1956 and 2015. Next, we set a restriction on the cointegrating vectors, representing ideal macronutrient ratio standards. This restriction was used as the null hypothesis that the detected long-run relationships among the three macronutrients were favorable, compared to the idealized macronutrient intake standard. We run the likelihood ratio tests for the full sample and sub-samples, by recursively increasing the number of observations obtained since 1978. Our results reject the null hypothesis, at the conventional level of significance, for the full sample and almost all sub-samples. These outcomes indicate that although the Japanese diet between the late 1980s and early 2000s were the closest to the ideal macronutrient ratios of proteins, fats, and carbohydrates, it is diverging since that time from these favorable ratios.
