For a number of reasons, the pricing of fluid milk in Canada is not subject to the rigors of the market. Given this, questions arise as to the appropriate form of regulated pricing. An increasingly common method is the use of formulas. A large number of possible formulas exist and the main types are outlined in this paper. In addition, each is evaluated in terms of a set of objectives and operational criteria, and a format for establishing a preferred pricing system is suggested.
Pour plusieurs raisons la fixation du prix du lait fluide au Canada n'est pas sujette aux rigueurs du marché. Étant donné cette situation, des questions se présentent quant à la methode fixer le prix du lait fluide. line méthode de plus en plus courante d'utiliser une formule. Un grand nombre deformulespossibles existe, et les differentes sortes sont exposées dans cet article. Cet article suggère la sorte de formule qui établira des prix qui satisfont l'intérél public comme les agences régulatrices le définissent. Ensuite, des formules canadiennes courantes sont comparées à une telle formule. 相似文献

This paper analyzes Colorado corn producers’ preferences over both private‐ and environmental public‐good production system attributes, and tests the robustness of alternative data reconstruction and estimation techniques. Irrigated corn production practices are characterized by intensive water and chemical use, resulting in nonpoint source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations (and several alternative fixed parameter specifications) uncover consistently positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The analysis also finds evidence of preference heterogeneity and a complementary relationship between the two environmental attributes. Analysis of this kind can be used by policy makers to predict behavioral responses associated with introduction of new technologies, or to assess welfare implications of agricultural policy changes and stricter environmental regulations. Dans le présent article, nous avons analysé les préférences des producteurs de maïs du Colorado concernant les attributs des systèmes de production de biens environnementaux publics et privés et avons vérifié la robustesse des techniques de rechange pour la reconstruction et l’estimation des données. Les pratiques de production de maïs irrigué sont caractérisées par l’utilisation intensive d’eau et de produits chimiques qui entraîne une pollution diffuse des plans d’eau ainsi que des problèmes d’érosion du sol. Nous avons utilisé des données tirées d’un sondage sur les préférences déclarées pour analyser les principaux attributs des systèmes d’irrigation expérimentaux proposés comme solutions de rechange aux pratiques actuelles. Les estimations du modèle mixte logit (et plusieurs spécifications de paramètres fixes) ont permis de découvrir des préférences uniformément positives concernant les profits, la réduction des risques et les systèmes ayant moins d’impact environnemental du point de vue du lessivage des nitrates et de l’érosion du sol. L’analyse a également montré l’hétérogénéité des préférences et l’existence d’un lien complémentaire entre les deux attributs environnementaux. Les décideurs pourraient utiliser ce genre d’analyse pour prévoir les réactions comportementales liées à l’introduction de nouvelles technologies ou pour évaluer les répercussions des changements de politique agricole et des règlements environnementaux plus stricts sur le bien‐être. 相似文献

We study a dynamic and infinite-dimensional model with incomplete multiple prior preferences. In interior efficient allocations, agents share a common risk-adjusted prior and subjective interest rate. Interior efficient allocations and equilibria coincide with those of economies with subjective expected utility and priors from the agents? multiple prior sets. A specific model with neither risk nor uncertainty at the aggregate level is considered. Risk is always fully insured. For small levels of ambiguity, there exists an equilibrium with inertia where agents also insure fully against Knightian uncertainty. When the level of ambiguity exceeds a critical threshold, full insurance no longer prevails and there exist equilibria with inertia where agents do not insure against uncertainty at all. We also show that equilibria with inertia are indeterminate. 相似文献

This article presents a qualitative study exploring service employees’ experiences of quality–productivity tensions in the workplace, and how they cope with such conflicts. Semi-structured interviews were conducted with 50 service employees. Content analysis suggests that organization-level conflict derives from the different channels that service organizations use to convey the importance of quality (e.g. training) and of productivity (e.g. rewards) to employees. During service interactions, employees experience conflict when standardization is violated and productivity is threatened. Our results demonstrate and explain employees' strategies for coping with the conflict between productivity and quality and with the ‘double message' they receive about these two goals. Many of these strategies are intended to ensure quality while maintaining productivity. We discuss the study's contribution to service science, and explain existing organizational mechanisms and processes for communicating the importance of quality and productivity to employees. Implications for service management are discussed. 相似文献

At the time, the negotiation of the SPS agreement was seen as a major accomplishment of the Uruguay Round. One of the first major tests of both the SPS and the WTO’s new dispute settlement system was the long standing and acrimonious dispute between the EU and the US and Canada over trade in beef produced using hormones. Both the SPS and the disputes system performed as expected but the EU, the loser in the case, has chosen to ignore the WTO Panel’s ruling and accept retaliation. As a result, the credibility of the WTO is threatened and the outcome suggests that new negotiations may be required. The issues in the case are outlined and implications for trade in biological products drawn. 相似文献

The risk behavior of financially distressed companies is studied using the shifting regimes regression model originally suggested by Brown, Durbin, and Evans. In addition, the presence of nonsynchronous trading is detected and the regression model is adjusted accordingly using Dimson's technique. The results reveal that the behavior of systematic risk as firms approach bankruptcy depends to some degree on appropriate identification of periods over which beta is constant and adjusting for nonsynchronous trading. The results also lend support to the importance of skewness and to some extent beta but not unsystematic risk in explaining the security returns of firms approaching bankruptcy. Finally, the behavior of equity risk is examined according to the outcome of the bankruptcy filing. 相似文献

The effects of two factors (congruity of product information with consumer expectations and perceived risk associated with the product) on strategies used by consumers to evaluate products are tested in the United States and Thailand. When product information does not match expectations, consumers in both cultures increase evaluation effort and shift from using summary representations stored in memory to evaluation based on actual product attributes. Perceived risk also enhances evaluation effort in both cultures, but does not result in a similar shift from category-based to attribute-based processing. © 1994 John Wiley & Sons, Inc. 相似文献

In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture's impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance of three agencies responsible for management of freshwater resources, and willingness to fund stream enhancement. We provide brief explanations for the failures of water resource management in New Zealand and report on options, including community-based responses that might address some of the mounting public, scientific, and government concerns about trends in water quantity and quality. A willingness to pay proposition, concerning riparian areas, included in the nationwide survey provides some evidence that the public are willing to pay for improved waterway management. Relevant non-market valuation studies also indicate that the public places considerable value on preservation values of water in New Zealand. 相似文献
