Trade negotiations between Canada and the United States are to begin in the near future. For there to be an ongoing free movement of commodities the question of nontariff barriers must be addressed in the negotiations. Livestock commodities are particularly prone to nontariff barriers due to the public health aspects of domestic regulations and the perishability of the products. Potential nontariff barriers in livestock and meat products are identified and the problems of normal negotiation procedures outlined. A proposal for an arbitration mechanism for the settlement of disputes is developed. It's essential elements are pre-approval of changes to regulations, extremely short arbitration periods and decentralized adjudication.
Les négociations de commerce entre le Canada et les États-Unis commenceront bientôt. Pour avoir un mouvement continuel des denrées, la question des barrières nontarifaires doit être adressée dans les négotiations. Les denrées bestiaux sont particulièrement portées aux barrières nontarifaires à cause des aspects de la santé publique dans les régulations domestiques et la nature périssable des produits. On identifie les barrières nontarifaires potentielles en des produits bestiaux et de viande. On indique aussi les problèmes avec les processus de négotiation normale. Une proposition pour un mécanisme d'arbitrage pour la résolution des disputes est developpée. Les elements essentiels de cette proposition sont l'approbation en avance des changements aux régulations, les périodes d'arbitration très courtes et les prononcements de jugements décentralisés.  相似文献

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown   总被引:4,自引:0,他引:4  
Theory suggests that economic instruments, such as pollution taxes or tradable permits, can provide more efficient technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing dramatic decreases in allowed pollution – the U.S. petroleum industry's phasedown of lead in gasoline. Using a duration model applied to a panel of refineries from 1971–1995, we find that the pattern of technology adoption is consistent with an economic response to market incentives, plant characteristics, and alternative policies. Importantly, evidence suggests that the tradable permit system used during the phasedown provided incentives for more efficient technology adoption decisions.  相似文献

North American Free Trade Agreement (NAFTA) was referred to by U.S. President Trump as one of the worst trade deals ever made. Given this billing, one might have expected the result of its renegotiation to be a major change to the trading relationship between the United States and Canada. The new United States, Mexico, Canada Agreement (USMCA), however, retains a great deal of its predecessor. This is particularly true for agricultural trade. Canadian market access into the United States remains virtually unchanged. No major domestic regulatory changes were agreed to by Canada. While there were concessions made on market access for U.S. products into Canada's heavily protected sectors where the supply management policy applies, they do not appear to threaten the system. While the value of the compensation has not yet been announced, compensation for losses that will be suffered by farmers producing under supply management is agreed in principle. The USMCA is an agreement to keep things pretty much the same.  相似文献

This research note reviews the existing literature comprised of dark tourism articles and chapters mentioning children. Publications meeting the search criteria were few. Accordingly, we offer possible reasons for the scarcity of research on children in dark tourism, including the legal constraints when researching with minors, the academic risk in undertaking a new field of research, and the substantial expertise needed to engage children in studies. We conclude with the compelling reasons to undertake such research: to inform interpretation of emotionally provocative sites for children, to understand and mitigate children's psychological distress at dark sites, and to advance theoretical work on children as tourists.  相似文献

The main aim of this paper is to investigate the effect of co-production practices with customers on service innovation. Specifically, we sought to determine whether dynamic capabilities (the specific abilities a company has to shape, reshape, configure, and reconfigure idiosyncratic assets to respond to changing technologies and markets) could mediate the effect of co-production on service innovation. In this paper, we examine the factors that could influence co-production practices and determine whether organizational commitment moderates the effect of co-production practice on an organization's dynamic capabilities. Using a survey approach of Taiwanese firms, we showed that dynamic capability fully mediates the effects of co-production practice on service innovation and that market orientation and customer matching have a significant influence on co-production practices. In addition, this study has empirically demonstrated that service firms would be well advised to engage in developing service innovation through enhancing their own dynamic capabilities.  相似文献

Prior to 1996, the Australian system of advertising self-regulation was regarded as a world model and many Asia-Pacific systems included components adapted from the Australian system. The recent changes to this system, encouraged by the abolition of the media accreditation system, consumer association pressure, criticism from the national advertisers association and the lack of a strong advertising agency presence, present an interesting framework in which to review the foundation concepts of self-regulation in advertising. This paper compares the new code of ethics with its predecessor and an international standard. It examines the performance of the code in terms of the number of complaints upheld and complaint by medium and product type and the voluntary response of advertisers. The findings suggest a weakening in the standard of advertising self-regulation in Australia, with fewer provisions in the Code of Ethics, a significantly fewer number of complaints upheld and no real power of enforcement. Although the case is Australian, it raises universal questions such as the vested interest of advertisers in controlling the process and roles of the consumer association, the media and the advertising agencies in guaranteeing the privilege of self-regulation.  相似文献

To attract students to the risk management and insurance profession, strategies need to be developed to overcome biases in their perceptions of the profession. This study attempts to determine some of those perceptions of students—specifically a group of business career high school students and a group of college students enrolled in an introduction to business course—about the personality traits of insurance professionals. A Personality Factor Questionnaire previously used extensively in other research was used to measure differences in student perceptions of personality profiles of different professions. We also measured how student characteristics such as age, sex, and expected college major influence student perceptions of these traits. The overall general conclusion was that perceptions of the profession are not as negative as many imagine, but do require some substantive work to improve, even among students seeking business careers.  相似文献

The King, upon a representation from His Subjects in the West Indies, that the introduction of the Bread Fruit Tree among them would be a Universal good to constitute an article of food…
I was therefore directed to sail forthwith … for the Society Islands …
And there … to procure of the Natives as many Plants as I could stow on board Ship.
… I was to proceed … to St Vincent, one of the Windward Islands, and depositing One Half of my Plants there, I was to go immediately to Jamaica.

This paper is the result of survey investigation the attitudes of Western Canadian farmers toward two biotechonological products, ENFIX-L and PB-50. Farmers were asked to rate both the importance and the performance of 21 attributes of the products. Soil depletion was found to be an important concern to many farmers. personal and environmental risks were less of a concern. Overall, it was found that the non-biotech-nological aspects of a product would prevail in purchasing decisions.  相似文献

Although most marketing researchers and texts recommend guaranteeing respondents anonymity in mail surveys, emirical evidence on this issue is dated, and often is based on results from student or occupational samples. The present study examines the impact of anonymity on item omission, response bias, and response quality. Based on a representative sample of respondents from a Southern SMSA, it was found that lack of anonymity had minor effects on response variables. Anonymous respondents provided slightly less information to complex questions, and lower-income respondents, nonwhites, and homeowners were more likely to identify themselves on the return envelope. Yet, the responses of these groups did not differ substantively from answers of other respondents on the range of questionnaire items examined.  相似文献
