Canada's wheat grading system is largely based on visual criteria and it is based on relatively high quality standards. A strict varieties licensing system exists to maintain the integrity of the grade standards. One of the consequences of the licensing system is that higher yielding, lower or different quality wheats have not been grown in Canada until recently. The basic objective of this paper is to examine some of the consequences of the regulatory strategy of limiting wheat production to the traditional high quality wheats. This question is analyzed in the context of important changes in the international grain markets. Using a partial equilibrium trade model this paper estimates that if higher yielding wheats were permitted to be grown, annual producer gains would be 5 to 17 percent of current net farm income.
Le classement des blés au Canada est basé sur des critères visuels qui sont de hautes qualités. Le système actuel d'homologation des variétés est tel que l'intégrité de ce système est maintenue. En conséquent, ce système n'a pas encouragé la cultivation des blés de hauts rendements ou des varietés différentes que tout récemment. L'objectif principal de cette étude est d'examiner quelques unes des conséquences de la stratégic de la réglementation visant à limiter la production du blé aux variétés de hautes qualités. Cette question est adressée dans le contexte des changements importants qui ont eu lieu dans le marché international des grains. A l'aide d'un modèle d'équilibre partiel des échanges, la présente étude démontre gu'en permettant la production des blés de hauts rendements, le gain annuel aux producteurs serait de 5 à 17 pourcent du revenue agricole net. 相似文献

Analysis of the US cruise line industry 总被引:1,自引:0,他引:1
J. S. Perry Hobson 《Tourism Management》1993,14(6)
The cruise line industry has been through a metamorphosis. From being a declining mode of travel in the 1960s, the cruise line industry turned the corner in the 1970s and became one of the fastest growing segments of the wider tourism industry during the 1980s. This paper examines the reasons behind this growth, the current structure of the US cruise industry and the issues facing the industry in the 1990s as it heads towards the next century. 相似文献

Does hedging add value to the firm, and if so, is the source of the added value consistent with hedging theory? We investigate jet fuel hedging behavior of firms in the US airline industry during 1992–2003 to examine whether such hedging is a source of value for these companies. We illustrate that the investment and financing climate in the airline industry conforms well to the theoretical framework of Froot, Scharfstein, and Stein (1993). In general, airline industry investment opportunities correlate positively with jet fuel costs, while higher fuel costs are consistent with lower cash flow. Given that jet fuel costs are hedgeable, airlines with a desire for expansion may find value in hedging future purchases of jet fuel. Our results show that jet fuel hedging is positively related to airline firm value. The coefficients on the hedging variables in our regression analysis suggest that the “hedging premium” is greater than the 5% documented in Allayannis and Weston (2001), and might be as large as 10%. We find that the positive relation between hedging and value increases in capital investment, and that most of the hedging premium is attributable to the interaction of hedging with investment. This result is consistent with the assertion that the principal benefit of jet fuel hedging by airlines comes from reduction of underinvestment costs. 相似文献

Consolidation in the banking industry has sparked concern about the survival of small banks, particularly as it relates to the availability of credit to small businesses. However, if small banks have an advantage in processing credit information, compared to large banks, they should continue to survive in a competitive environment. We evaluate risk-adjusted commercial loan yields (gross yields less net charge-offs and the risk-free rate of return) at small and large banks for the period of 1996 through 2001. Our primary finding is that, after controlling for market concentration, cost of funds, and a variety of other factors that might influence yields, smaller banks earn greater risk-adjusted yields than larger banks. This result suggests that small banks make better choices from the available small business loans and is consistent with the notion that these banks have an information advantage in evaluating credit. 相似文献

短期事件对旅游的影响:以中国SARS危机为例 总被引:13,自引:0,他引:13
通过回顾近年来世界各国发生的短期危机对旅游产生的影响,重点分析2003年的SARS疫情给中国经济特别是旅游业造成的重大损失,讨论了不同的短期危机对旅游的不同影响以及旅游在危机后的不同恢复时间。旅游业对短期危机缺乏足够的防御能力,但通常能较为迅速的走上复苏之路。在这个过程中,适当的危机管理措施和有效的恢复策略是十分重要和不可或缺的。 相似文献

Two years ago RIMS formed the Risk Management Roundtable to identify trends and issues affecting the field and to develop mechanisms to broadly disseminate views and concerns. In March 1990 Risk Management published the Roundtable's first article, "The 1990s: The Decade of Risk Management," developed by its "new risk team." Focusing on how the risk management function is performed and how it is perceived, particularly by senior management, the article generated ample discussion. In this issue the Roundtable's workers' compensation team explains how the system's original intent has been eroded. The team also offers advice on how various players, including workers, employers, doctors, lawyers, insurers, regulators and legislators, can help cure the system.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Performance lies arise both from individual and from situational causes, but in this article, the attention is on situational causes. These are generally triggered by loyalty to the coalition, which is expressed through the continued use of performance lies. Because performance lies help create a boundary around the coalition that insulates its activities from top management, performance lies enable members of the coalition to exercise a greater degree of internal control. Naturally, such lies are dysfunctional, resulting in the avoidance of difficult issues and problems and compromising the organization's ability to adapt to a changing environment based on accurate information. 相似文献

Most of the literature on transboundaryenvironmental problems treats population ineach country or region as constant, ignoringpopulation mobility. We showed previously thatif there is perfect population mobility betweenregions, and populations are homogeneous, asocially efficient outcome can be supported asa Nash equilibrium of the game of uncoordinatedpolicy setting, even without any internationalenvironmental agreement. In the present paperwe introduce heterogeneous population, and showthat when people differ, a non-cooperativeoutcome is generally inefficient. We alsodemonstrate that for a particular set ofobjective functions for the regionalgovernments, there is an equilibrium of thegame of uncoordinated policy setting that isefficient. Finally, we give an example wherethe decentralized outcome is efficient whenthere is no population mobility, butinefficient when there is population mobility. 相似文献
