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.

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.

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.

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.

Currently, in Japan, population aging is increasing and the medical expenses are exerting pressure on people’s finances. For improving public health and reducing medical expenses, promoting the use of food with health claims is important. However, consumer’s perceptions of food with health claims are vague. Thus, for clarifying the perceptions of these claims, we apply two methods-network analysis and sentiment analysis̠-in this paper. According to the analysis results, some consumers could not recognize the correct usage. Therefore, it is necessary to spread awareness regarding the correct intake method. Moreover, as the results suggest, Food for specified health uses most likely has a pioneer advantage against Foods with function claims and food with nutrient function claims.

The Japanese food manufacturing industry has been expected to strengthen the country's industrial competitiveness and local economy revitalization. This article examines the technological capability and profitability of food manufacturing companies in Hokkaido, which is considered one of the most active food production areas in Japan. Financial information and one output from innovation activities, specifically patent information, have been utilized and analyzed. The analysis revealed four findings. First, very few strong relationships were seen between the sales amount and net profit to sales of Hokkaido food manufacturing companies. Many small and medium companies with high profitability were prevalent. Moreover, although food companies in the Tokachi district were smaller in size, they achieved higher profitability compared to food companies in Sapporo City. Second, food companies who possess patents showed higher profitability than those who do not possess patents. Third, food companies with high technological indicators such as the number of patent examinations and cited patents seemed to be capable of further increasing their business performances. Fourth, the technological capability of the whole region including Sapporo City and the Tokachi district showed an increasing trend in general. Although the Tokachi district still had a small number of patent applications, this area exhibited rapid improvement in its technological capability.

This report examined the following two points When the globalization of the dairy products market of Japan greatly progresses by TPP agreement, the domestic dairy industry comes under what kind of influence, and what kind of problem do they face in the near future? What kind of measures should be prepared for to maintain stability of the dairy farming and dairy industry of Japan when assume them a precondition? The basic point at issue of that case is three items. 1) Reinforcement of the dairy farming infrastructure. 2) Stabilization of dairy farming management. 3) The correspondence to the change of the external factor over dairy farming and the dairy industry to show a stronger volatility. In addition, this report overlooked the present situation of the Japanese dairy farming and gave an outline that was the basic condition.

Interactive exchange of information and opinions on risk is required in the field of food-related risk communication, and effective methods for communication are explored. In the case of effects on health by radioactive substances derived from the accident at Fukushima Daiichi nuclear power plant,people are extremely anxious about the health effects, regard government and media with distrust and tend to lack scientific information in face of the emergency, there is a compelling need for the interactive risk communication including elaborate information processing. This study aims to provide an interactive risk communication model and examine effectiveness of it through focus group communication. This model has the following characteristics; the purpose is not persuasion; scientific information that answers questions from participats is created through communication; experts make a presentation in two segments, followed by a group discussion only by participating citizens (‘horizontal discussion’). The examinations were conducted in Tokyo and Kyoto from June to August, 2011, on 51 people: 8 groups and confirmed the effectiveness by evaluation of the method and changes in knowledge and risk perception of participants.

The production and utilization of biofuel is promoted in the U.S., and it is estimated that the U.S. biofuel market will continue to expand in the future. The Environmental Protection Agency (EPA) decided partially waiver to allow gasoline that contains up to 15 volume percent bioethanol (E15) for certain motor vehicles on October 13, 2010. EPA approved the waiver for 2007 and newer passenger cars, light trucks including sports utility vehicles (SUV). This study uses dynamic partial equilibrium model to examine how the increasing U.S. bioethanol blend ratio on the world corn market. The baseline projection is based on a series of assumptions about the general economy, agricultural policies, and technological growth in all countries and regions during the projection period. In addition to this, it is assumed that gasoline stations in Mid-West states would install E15 equipments for certain vehicles. This study supposes two scenarios to compare with baseline scenario. If the U.S. government doesn't grant the waiver, world corn price would decrease by 1.10% in 2011/12 and 4.14% in 2020/21. In addition to this, if gasoline stations in all U.S. states install E15 equipments, world corn price will increase by 5.03% in 2011/12 and 14.01% in 2020/21. The results of this study indicate that the increasing of U.S. bioethanol blend ratio will impact on the world corn market and their impact will increase gradually from year to year.

Consideration set is defined as a subset of all possible alternatives (Peter & Olson, 2008). Alternatives not included in the consideration set are never preferred. The purpose of this study is to elucidate the mechanism that the information of strawberry cultivars influences formation of consideration set. The consumer research conducted in the Metropolitan Area and Fukushima Prefecture shows several findings as follows. The variety-seeking factor and the habitual factor concerning purchase behavior influence the formation of the consideration set. Moreover, the consideration set is formed with non-awareness set, and suggests the possibility of accidentally preference. Furthermore, the positive feeling that naming brings also influences preference. As a result of clustering the respondent according to the decision making process, the type that prefers various cultivars prefers by the variety-seeking factor. These findings suggest the feasibility of the differentiation by the cultivar of the strawberry.

The purpose of this article is to investigate the structure of market channels and the impacts of the direct marketing on farm sales, focusing on the top one percent rice farms (large rice farms). We have used the agricultural census farm-level data, to which was applied propensity score matching. Our findings in this article are as follows. Firstly, more than half the large rice farms used multiple marketing channels and the number of market channels used were increasing. Secondly, direct marketing to consumers by farms ranked second and shipment to agricultural cooperatives ranked first for both large rice farms and all rice farms. Thirdly, in recent years, for large rice farms, the ratio of the implementation of direct marketing to consumers has been decreasing and the farms are changing shipping destinations from the direct marketing to consumers to retail sellers, food manufacturers and the food-service industry. Fourthly, the results of propensity score matching indicate that direct marketing to consumers increases farm sales for family-owned management entities, while this is not valid for organized management entities.

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.
