A cost function is used to quantify potential sources of gains from deregulation of the Norwegian salmon farming industry, an industry that has been heavily regulated in order to achieve a regional dispersion of production and profits along the entire coastline. It now seems to be widely recognised that the regulations have led to cost inefficiencies. A region-augmented cost function with data from 282 fish farms for 1988 is used to estimate regional productivity differences, i.e. differences in the total cost of producing salmon in one region compared to another. It is found that the potential gains from deregulation may be substantial. 相似文献

The performance of wholly owned, wholly rented and mixed tenure farms in the Farm Management Survey sample for England and Wales is compared on a range of criteria, controlling farm size and type. Mixed tenure farms are found to perform noticeably better than ‘pure’ tenure types. Possible explanations for inter-tenure differences in performance are reviewed under the headings of capital provision, farmer motivation and resource mobility. Evidence from the FMS and from interviews with 48 farmers provide only weak support for hypotheses relating performance to capital endowments, the ‘spur’ of market rents or asset appreciation. Findings on changes in farm size and tenure, however, suggest that tenure could be determined by, rather than being a determinant of, farm performance. 相似文献

This article reviews the circumstances under which contract farming, as one form of vertical integration, is necessary to secure rapid and efficient co-ordination and adaptability within systems of food production/marketing/distribution. A review of American experience and attitudes indicates that contracting in the U.S.A. has been successful in matching farm production to the needs of consumers more quickly and economically than otherwise would have been possible. Contract terms have generally been ‘fair’ to United States farmers, partly as a result of a strong co-operative system, including a large number of bargaining co-operatives, but also as a result of strong competition between American agri-businesses. American experience and conclusions can be transposed to British circumstances. However, there should be greater publicity and analysis of contract terms, as well as more complete information on the financial performance of the agri-business operations of conglomerates and other multi-product businesses. 相似文献

A preliminary case is made for intensive and long-term socio-economic survey work in farming systems research (FSR), as opposed to a reliance on rapid appraisals. A sampling methodology is described, based on collection of a detailed sample frame, which allows the selection of samples which can be related directly to each other, through common respondents. Thus causal relationships can be determined in one sample and, by extrapolation, linked to attributes found in another. The sampling method also makes it easy to select farmers with specific attributes for on-farm trial sites, and allows a more informed interpretation of agronomic results in relation to farm management criteria. 相似文献

The growth of contract production in certain types of farming is noted, and the main implications of this form of business organization for on-farm decision-making and capital acquisition are identified. The purposes of contracting, from both processor firm and farm viewpoints are discussed, and the broiler industry is used to illustrate the development of contracting. 相似文献
