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

Does Hedging Affect Firm Value? Evidence from the US Airline Industry   总被引:1,自引:0,他引:1  
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

Asymmetric Network Interconnection   总被引:1,自引:0,他引:1  
We develop a model of competition between interconnected networks,that allows for carriers to differ in size. Under two-partpricing, we show that because of asymmetry the larger network willalways prefer a reciprocal interconnection charge be set at cost.For sufficiently large asymmetry the smaller network will have thesame preference. Under the assumptions of our model a particularly simple regulation is optimal – if carriers cannot agree on the terms of interconnection, the larger carrier is entitled to select the access price which is then applied reciprocally.  相似文献

Most companies are under pressure to improve the environmental sustainability of their supply chains. However, there is considerable variance in companies' ability to successfully deploy environmental management projects. One important factor, according to articles in the academic and business press, is the ability of champions of sustainable supply chain management (SCM) projects within organizations to gain the commitment of colleagues (e.g., other managers from a variety of functions) to help these projects succeed. Therefore, this paper examines variables that affect a project champion's ability to gain this commitment from colleagues. In particular, building on existing research, this research employs a video‐based experimental design to examine the effect of the influence approach that the project champion employs, the values of the person the champion is trying to influence, and the organizational climate. The results suggest that organizational climate and certain individual values directly affect commitment. There are also interactions between values and influence tactics. The research adds to the field's growing knowledge on the antecedents of sustainable SCM within companies while providing valuable guidance for environmental champions and for top managers.  相似文献
