For the ten crop seasons 1979-80 to 1988-89, returns to producers in the Australian wheat industry were underwritten by a government-guaranteed price floor. Similar schemes operate in other rural industries (dairy, apples and pears, dried fruits). Although the underwriting provisions have only been triggered once (in the 1986-87 season), the provision of this scheme has acted to reduce the risk normally associated with returns to producers of wheat in all years of its operation. This reduction in risk has been granted free-of-charge by the Commonwealth Government. The guaranteed price can be viewed as a put option taken out by the Government on behalf of growers — it gives growers the option to sell to the Australian Wheat Board at this floor price. The aim of this paper is to apply to this underwriting arrangement the Black-Scholes formula for valuing options, in order to estimate the cost that growers would otherwise have had to pay to obtain cover (through put options) equivalent to the guaranteed price. We also estimate the magnitude of this form of assistance to the industry, which (until now) has not been taken into account unless the returns to growers fell below the guaranteed price. 相似文献

A resurgence of consolidation in the U.S. meat packing industry in the past few decades has stimulated academic and policy debate. Issues raised include the role of cost economies in driving these patterns, and the effects on the agricultural sector (cattle producers) from market power. Here, plant level cost and revenue data for U.S. beef packing plants are used to estimate a cost-based model incorporating cattle- and output-market pricing behavior. The robust results indicate little market power exploitation in either the cattle input or beef output markets, and that any apparent evidence is counteracted by cost efficiencies such as utilization and scope economies. 相似文献

The sustainability of farming systems is currently under debate. There is concern that technological and other changes have long-run consequences, which may compromise future levels of desired outputs from agricultural and other resources. The paper traces developments in the theory of sustainability and discusses their application at the farm level. Findings include firstly, that sustainability should be regarded as an emergent property of an agricultural system. Its operational definition at the farm level thus may not apply at other levels in the hierarchy. Secondly, whilst individual farmers may attach value to “sustainability” goods, they are unlikely to adopt socially optimal levels without regulation or incentive. Finally, since sustainability issues at the farm level are usually long-run, dynamic and have social dimensions, a central task for farm management researchers lies in investigations which allow tradeoffs between different sustainability criteria to be determined and then optimised according to society's norms. 相似文献

This article discusses how the “decision style” of an administrator influences the adoption and use of particular decision models. Several “interactive” and “analytical” decision models often used to guide decision making are described and critiqued to point out their virtues and deficiencies. Propositions are suggested that contend that “systematic,” “judicial”, “speculative”, and “intuitive” styles have clear-cut preferences for a particular decision model. This model seems to be used, even when another would be more suitable. Effective decision makers are postulated to adapt their styles, or at least to see the benefits of different styles. Mixed-mode models are proposed that seem to simulate the behavior of successful decision makers. 相似文献

In 1977 the Foreign Corrupt Practices Act (FCPA) was enacted to penalize US firms and their employees for paying bribes to foreign government officials. If bribe payments influence the awarding of contracts and the FCPA regulation differentially affects US exporters compared to foreign competitors, then US exporters' bribe-paying ability and market share would be expected to decline. This study provides empirical evidence that the FCPA had a negative effect on US exports to non-Latin American countries but not to bribery prone ones in Latin America. 相似文献
