The purpose of this paper is to investigate the preference change in the demand for meat subject to random coefficients in Saudi Arabia. A Fortran 77 program has been designed to estimate the demand function for meat using Kalman filtering techniques and maximum likelihood approach. The initial values of the coefficient and covariance estimates are an essential prior information in the Kalman filtering techniques. Results provide substantial random coefficients in red meat, implying important structural change occurs in red meat more than poultry and fish demand. 相似文献

Consumers are increasingly aware of the link between their lifestyle choices and the risk of noncommunicable diseases. A dynamic approach incorporating this linkage in food demand is developed, where consumers maximize utility over time by choosing fat intake to control their cumulative fat level. The resulting dynamic indirect utility function and household data on meat, fish, and dairy consumption are used to estimate a censored demand system. Results show that consumers consciously adjust, but not instantaneously, their cumulative fat level. Highly educated households have a faster rate of adjustment of cumulative fat. When cumulative fat level increases, consumers shift to dairy or white meat from red meat products. 相似文献

目的 通过对乌兰察布市农业产业结构调整的经济效益进行定量和定性的分析研究,为该市农业产业结构调整以及农业产业经济发展提供有益借鉴。方法 文章运用综合比较优势指数测算农业产业的比较优势,构建产值增长贡献率模型分析农业结构调整对农业经济的影响,并对农业产业结构调整与农业经济增长的影响关系进行回归分析。结果 乌兰察布市农业产业的显著综合比较优势主要集中在集宁区、卓资县、四子王旗、察哈尔右翼前旗,并且多数农业产业的规模比较优势相较于产量比较优势更为突出;通过预测模型看出,农业产业结构调整对农业经济增长呈负向贡献率;从回归分析得出,小麦、玉米、莜麦、豆类、马铃薯、油料作物、蔬菜瓜果产值每增加1%会分别为乌兰察布市农业总产值带来0.020%、0.057%、0.015%、0.018%、0.223%、0.847%、0.468%的经济增量。结论 玉米、油料作物、蔬菜瓜果和马铃薯对农业产业总值推动力较强,小麦、豆类和莜麦对农业产业总值的推动力相对较弱;乌兰察布市农业结构调整对农业经济增长的影响不太显著。 相似文献

In this study, Canadian household meat consumption behavior in exotic (deer and elk meat) and traditional meats (beef, pork, chicken, turkey, bison, and seafood) is examined. This research introduces some differences in public response to transmissible spongiform encephalopathies (TSE) risks across consumer segments from different sources of meat supply, including hunted meat. The analysis uses a combination of survey and household meat purchase data that include a balanced household panel of 2,393 households per year across time. A two-step estimation procedure is used with a probit model in the first step (consume or not) and a doublelog–translog two-stage demand system in the second step (level of consumption). It is assumed and tested that household sociodemographics, consumers’ risk perceptions/attitudes, and media coverage of bovine spongiform encephalopathy (BSE) and chronic wasting disease (CWD) are underlying demand shifters in consumers’ daily meat purchase decision. The results suggest that households who obtain venison from hunting show the highest confidence in venison safety. Exotic meat preferences negatively affect traditional meat consumption in the daily diets of households who purchase traditional meats from stores and obtain venison from hunting. In response to the media coverage of BSE and CWD, exotic meat eaters are less sensitive to animal disease media information than the general population. 相似文献

A model analyzing the economics of sheep farming is formulated. The basic idea is simple. Sheep are capital and they are held by farmers as long as their capital value exceeds their slaughter, or meat, value. Farmers are therefore portfolio managers aiming to find the optimal combination of different categories of animals. Yields are compared with the yields from other assets. The model is formulated within a Northern Scandinavian economic and biological setting with a crucial distinction between the outdoors grazing season and the indoors season, and with adult sheep and lambs being different categories. In the first step, the management problem is analyzed with only the meat income of the farmers taken into account. In the next step, income from wool production is considered as well. The analysis provides several results that differ from standard harvesting theory. 相似文献

目的 分析山西省农业经济增长、结构、竞争力优势度和区域农业资源配置现状及合理性,为乡村振兴产业动力发展提供参考。方法 文章以全国为参照,运用比较优势指数和Esteban-Marquillas偏离份额法拓展模型,综合探析山西省农业经济增长和产业结构现状。结果 (1) 2000—2019年山西农林牧渔业经济总量整体保持增长趋势,农林牧渔业经济增加值占GDP比重在波动中呈下降趋势,与全国同产业比值稳定在1.225%。(2)结构比例演变相对稳定,以种植业为主,牧业为辅,渔业林业比重低;结构调整以种植业略下降,林业略提升为主要特征。农作物以谷物、豆类、薯类具有比较优势,尤以谷子、胡麻籽、高粱、绿豆、红小豆比较优势明显,明显高于全国水平。(3)偏离效应分析显示:种植业规模增长明显,但结构、竞争力、资源配置均处于劣势;林业结构和资源配置合理,但规模小,不具竞争力;牧业发展规模、竞争力、资源配置优势均较好,但结构尚不合理;渔业产业规模小,增长优势不明显,结构发展程度低,竞争力差。(4)动态变化中份额分量演变高度一致,种植业和牧业呈现明显的正负交替和此消彼长态势。农业经济增长优势整体表现为由南向北依次减弱的趋势,各地区结构偏离效应均为负,份额和结构分量区域间差异较小;竞争和配置分量偏离效应空间分布复杂,差异较大。结论 与全国相比,研究期内山西农业经济增长趋势不明显,竞争力低于全国水平。其中种植业和牧业结构需要进一步优化,提高资源配置合理性;林业结构和资源基础好,但发展较晚,亟待提高竞争力;渔业规模小,发展程度尚低。不同地区之间的协同性较差,可通过优化结构和分工,提高区域协作能力。 相似文献

This paper simulates pig producer and slaughterhouse income losses due to a classical swine fever outbreak in Finland. The analysis explicitly takes into account that an outbreak of a highly contagious animal disease can shrink export demand for pig meat. After having observed the disease and its impact on pig meat price, producers can optimize animal stocks thought insemination decisions, which affects the number of animals in a dynamic manner. The income losses of pig industry were estimated to be less than €30 million. The losses were mainly due to price movements caused by an export demand shock. The results suggest that if the outbreak causes distortions in meat trade, the disease can cause substantial losses to the industry even if it has directly a small impact on the number of animals on farms. We also found that the optimization could reduce disease losses significantly, even more than 50%. 相似文献
