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

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.  相似文献

This paper contains a critique of existing legislation which deals with hazardous waste disposal and expands on the efforts made by the Office of Technology Assessment and other economists to develop a public policy which will deal effectively with the problems associated with hazardous waste generation and disposal. A new policy is set forth here which encourages both waste reduction and safe disposal while providing revenue to pay for cleanups at Superfund sites.  相似文献

The House and Senate of the United States Congress recently passed legislation that directs the FCC to establish a system for using auctions to allocate the use of radio spectrum for personal communications services. There is a unique and unprecedented set of issues that arise in this context, which are of interest to economists, industry analysts, regulators, and policymakers. We discuss these issues and evaluate their likely impact on the outcome of the spectrum auctions. In addition, we argue that there may be pitfalls in the auction procedure adopted by the FCC, and we discuss possible alternative procedures.  相似文献

Previous research on unit management buyouts, UMBs, has shown that selling firms benefit from the selloff transaction. The current research demonstrates that when the selling firm has either poor liquidity or poor earnings, selling firm shareholders do not benefit as much. We hypothesize that the unit managers have knowledge about the selling firm's difficulties so they do not pay as large a premium for the assets. Since the unit managers technically are employed by the selling firm shareholders, their bargaining to achieve a better price is an agency cost. Finally, selloff frequency does not affect seller abnormal returns.  相似文献

This study investigates ethical decision-making by considering the differences in ethical judgments between undergraduate business and MBA students on selected ethical issues facing employees and managers of today's businesses. The study further investigates differences in ethical judgments between undergraduates and MBAs in terms of a perceived position as an employee or as a manager. The findings indicate that undergraduate students tend to be more ethical than MBA students and that both groups tend to be more ethical when they perceive themselves as managers rather than employees. The authors discuss the implications for both business practitioners and educators.Shohreh A.
