Input price variability is an important source of risk for corporations that process raw commodities. Models of optimal input hedging are developed in this paper based on the maximization of managerial expected utility. The relationship between hedging strategies and output decisions is examined to assess the impact of the ability to set output prices on futures market participation. As a firm's ability to set output prices diminishes in the short run, input futures positions increase although the optimal hedge ratio may either increase or decrease. For a perfectly competitive firm, however, shifts in output price caused by input price changes provide a natural cash market hedge of input price risk and reduce the firm's optimal input futures position. 相似文献

In this article, we advocate more extensive use of the benefit function in specifying price-dependent or inverse demand models. We demonstrate how duality theory may be used to establish the interrelationships between the Marshallian (or Hicksian) inverse demands and Luenberger's adjusted price functions, allowing estimable inverse demands to be derived directly from a benefit function. We estimate two systems of inverse demands for Japanese quarterly fish consumption. Results indicate that the procedures and methods employed here appear promising, and may prove beneficial for quantity and welfare analysis when modeling systems of inverse demand functions. 相似文献

In one way or another, all environmental and natural resource problems associated with overexploitation or under provision of public goods, arise from incompletely defined and enforced property rights. As a result private decision makers do not consider or internalize social benefits and costs in their production or investment actions. The gap between private and social net returns results in externalities – harmful effects on third parties: overfishing, excessive air pollution, unwarranted extraction or diversion of ground or surface water, extreme depletion of oil and gas reservoirs. These situations are all examples of the 'The Tragedy of the Commons'. In this paper, I consider options for mitigating the losses of open access: common or group property regimes, government tax and regulation policy, more formal private property rights. I briefly summarize the problems and advantages of each option and describe why there has been move toward rights-based instruments in recent years: ITQ (individual transferable quotas), tradable emission permits, and private water rights. Introductions to the papers in the special issue follow. 相似文献

Bob Quinn spent 20 years propagating an ancient Egyptian wheat variety that is generally known as Khorasan wheat. Bob trademarked his wheat variety using the brand name "Kamut® ." Kamut® brand wheat contains some nutritional, health, and taste advantages over modern wheat varieties, but lacks some of modern wheat's agronomic advantages. Kamut® brand wheat is organically produced, and is used to make cereals, breads, cookies, snacks, pancakes, bread mixes, bulgur, pasta, and baked goods. Whole wheat products produced from Kamut® brand wheat are less bitter than those produced from modern wheat varieties. Europe represents approximately two-thirds of the market for this product. 相似文献

Despite rapid growth in the number of town centre management schemes in the UK there have been few attempts to consider this topic from an academic perspective. This article develops a typology of town centre management schemes, based upon a comprehensive review of existing literature. The criteria of organizational structure and resource origin are identified as primary influences in the initiation and development of such schemes. The article concludes by outlining a research agenda which considers both local governance and spatial and temporal themes in the initiation and development of town centre management. The analysis of such factors is vital to a fuller understanding of this area. 相似文献

This study investigated the possible effect of television program types on the recall performance of humorous television commercials. An experimental design was developed to test the relative performance of the same humorous and non-humorous ads in three different contextual environments—situation comedy, action/adventure, and documentary. The findings indicate that the recall performance of commercials and of the product or service promoted are both affected by the program environment within which the ads appear. 相似文献
