Latest research activity on the standard of high-voltage impulse in Japan

IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, Issue 5 2007
Takayuki Wakimoto Member
Abstract A national-standard-class impulse voltage measuring system in Japan was developed in the consignment research of the Ministry of Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO) from 1998 to 2006. The standard measuring system for the impulse voltage measurements is to be managed by the Japan High-voltage Impulse testing Laboratories Liaison (JHILL) established under the Japan Electric Machine Industry Association (JEMA). In this paper, the composition of this standard measuring system, its performances and international compatibility, the domestic traceability system and related latest activities are described.

Food safety and consumer willingness to pay for certified traceable food in China

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 8 2010
Lingling Xu
Abstract BACKGROUND: The September 2008 melamine outbreak in China has adversely affected perceptions of food safety among consumers. This paper presents a survey of the perception of food safety and willingness to pay for certified traceable (CT) food among the citizens of Jiangsu Province. It presents the critical necessity of establishing a food traceability system (FTS) to address possible similar outbreaks in the future. RESULTS: The results show that 36% of the respondents are strongly dissatisfied with food safety conditions in the province. Only 37% of the respondents have heard of FTS. Among the respondents who chose to buy CT food, 32% were unwilling to shoulder the extra cost. The consumers' overall satisfaction with food safety, awareness of FTS, gender, age, educational level and income are the main determinants of Chinese consumers' willingness to pay for CT food. CONCLUSION: Based on the results, it is proposed that the Chinese government pay attention to the mentality of its citizens when establishing an FTS and take measures to lift consumers' willingness to pay for CT food. Results of this study will provide valuable insights to developing countries. Copyright © 2010 Society of Chemical Industry [source]

Time-varying Armington elasticity and country-of-origin bias: from the dynamic perspective of the Japanese demand for beef imports

AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 1 2010
Shigekazu Kawashima
Elasticities of substitution, often called Armington elasticities, reflect incomplete substitutability because of perceived product characteristics. This study divides the determinants of the Japanese demand for beef imports into two factors: (i) substitution elasticity and (ii) country-of-origin bias, and demonstrate how these measurements are associated with trade policy and food scare events. The Japanese beef industry serves as a case study to evaluate the multifold impact of import liberalisation and a series of bovine spongiform encephalopathy (BSE) outbreaks. A time-varying parameter model is used to shed light on the dynamic effects of the import liberalisation and BSE outbreaks on the measurements. The estimation results reveal that the estimated substitutability and country-of-origin bias are very sensitive to the BSE cases, but not to the process of trade liberalisation. The results also confirm that as a result of the BSE outbreaks, the major factor of the Japanese demand for beef imports has changed from relative prices to the country-of-origin effect, thereby emphasising the importance of a traceability system and promotional activities, which would help in the formation of the country-of-origin effect.

The Economics of Voluntary Traceability in Multi-Ingredient Food Chains

AGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 1 2010
Diogo M. Souza-Monteiro
The consumption of multi-ingredient foods is increasing across the globe. Traceability can be used as a tool to gather information about and manage food safety risks associated with these types of products. The authors investigate the choice of voluntary traceability in three-tiered multi-ingredient food supply chains. They propose a framework based on vertical control and agency theory to model three dimensions of traceability systems: depth, breadth, and precision. Their analysis has three main results. First, full traceability is feasible as long as there are net benefits to a downstream firm that demands traceability across all ingredients. Second, horizontal network externalities are positive because an increase in the level of traceability in one ingredient requires a similar increase in others. Finally, vertical network effects will be positive insofar as willingness to pay and probabilities of food safety hazards increase.

Traceability in the Canadian Red Meat Sector: Do Consumers Care?

CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2005
Jill E. Hobbs
Increased traceability of food and food ingredients through the agri-food chain has featured in recent industry initiatives in the Canadian livestock sector and is an important facet of the new Canadian Agricultural Policy Framework (APF). While traceability is usually implicitly associated with ensuring food safety and delivering quality assurances, there has been very little economic analysis of the functions of traceability systems and the value that consumers place on traceability assurances. This paper examines the economic incentives for implementing traceability systems in the meat and livestock sector. Experimental auctions are used to assess the willingness to pay of Canadian consumers for a traceability assurance, a food safety assurance, and an on-farm production method assurance for beef and pork products. Results from these laboratory market experiments provide insights into the relative value for Canadian consumers of traceability and quality assurances. Traceability, in the absence of quality verification, is of limited value to individual consumers. Bundling traceability with quality assurances has the potential to deliver more value. La traçabilité accrue des produits et des ingrédients alimentaires dans la chaîne agro-alimentaire a été mise en valeur dans les récents projets de l'industrie canadienne du bétail et représente un aspect important du Cadre stratégique pour l'agriculture (CSA). Bien que le concept de traçabilité soit habituellement et implicitement associéà la sécurité et à la qualité alimentaires, très peu d'analyses économiques se sont penchées sur les fonctions des systèmes de traçabilité et sur la valeur que les consommateurs accordent aux garanties de traçabilité. Cet article étudie les stimulants économiques de la mise en ,uvre des systèmes de traçabilité dans l'industrie de la viande et du bétail. Des ventes aux enchères expérimentales permettront d'évaluer si les consommateurs canadiens sont prêts à payer pour obtenir une garantie de traçabilité et de sécurité alimentaire ainsi qu'une garantie de méthode de production chez les éleveurs de b,uf et de porc. Les résultats de ces expériences obtenues dans ces marchés de laboratoire fourniront un aperçu de la valeur relative des garanties de traçabilité et de qualité pour les consommateurs canadiens. En l'absence de vérification de la qualité, la traçabilité ne présente que peu de valeur pour les consommateurs. Par contre, une plus grande valeur lui serait accordée si elle était associée à la garantie de la qualité. [source]
