Expenditure on different categories of meat in Greece: the influence of changing tastes

This paper employs a latent variable approach to isolate the effects of changing tastes on the share of total meat expenditure on different categories of meat products in Greece during the period 1965–1995. We find that changes in the relative expenditure on different categories of meat cannot be explained by changes in the relative prices of the different meat products and increased expenditure alone. For pork products in particular, the increase in the share of expenditure has been greater than would be expected as a result of the relative fall in their price. The increase can therefore be associated with changes in taste. This finding is of general interest to those conducting empirical research into consumer behaviour both in economies where there have been significant changes in patterns of food consumption, and where, as in the case of many less industrialised economies, rapid structural changes in food consumption patterns are still to come. It is also of importance to policy makers in assessing die effectiveness of advertising or promotional campaigns in influencing longer term changes in consumer preferences for different products.

品牌之死——基于品牌经济学视角的分析

基于品牌经济学视角对品牌之死的研究表明：品牌之死有自然死亡、突然死亡和长寿品牌3种基本类型；品牌之死即为需求之死；品牌的品类、品类度和品牌策略决定了品牌生命；因而延长品牌生命也应从这3方面制定相应的策略。     

认知语言学与词汇习得的内在机制

能源新论——兼论树立科学的能源观

能源在人类社会中是一个历史范畴,不同文明时期的主导能源之间有着深刻的历史联系。工业社会的主导能源本质上是化学能源,这决定了它的局限性。面对工业能源危机,人类必须开拓出比化学能源更深层次的新能源,这就是物理能源。物理能源的开发利用及其向主导能源的转化,是今日经济社会发展的必然趋势。     

生态经济学基本问题研究

如何审视生态系统、环境系统与经济系统之间的相互关系,关系到对生态经济学基本问题的科学理解,关系到如何运用科学发展观建设和谐社会、实现经济社会持续发展。本文以此为前提,深入研究生态经济学的基本问题,对生态价值、环境价值、经济价值层次的升级,逻辑上的升华及其内在联系进行了探讨。     

论中国特色社会主义经济学的核心范畴

确立中国特色社会主义经济学的逻辑起点，必须突出它的特殊性，而不能照搬以往的经济学。迄今，所有的经济学由于其任务和宗旨不同大体可分四种类型、四个逻辑起点。中国特色社会主义经济学根据它的任务和宗旨，需要在科学社会主义实践逻辑的基础上，进行科学抽象，分析其矛盾特殊性的三个表现及中国的个性，揭示以社会主义本质为核。范畴和逻辑起点的理论规定性，进而全面展开，创立新的架构。

Pure meat – Public perceptions of risk reduction strategies in meat production

Experience has shown that both the assessment and implementation of new technologies in food production are challenged by negative assessments of the technologies by the public. This article seeks to deepen our understanding of the concerns that may underlie negative attitudes to various kinds of risk reduction strategy in meat production, with the aim of distinguishing between forms of risk reduction in terms of their acceptability. The paper reports the result of a focus-group study. Six focus groups with Danish citizens (N: 5–9) were conducted during May 2006. The design of the groups took a bottom-up approach and included elements of meat quality, meat safety and risk reduction strategies. The study shows the dilemma risk reduction presents to members of the public. On the one hand, people want safe meat; on the other, the study showed that with the exception of hygiene practices, people generally have an aversion to risk reduction strategies. Some variation was found, however, in the rejection of the strategies. Thus, more acceptable strategies are characterised by a low degree of technological interference, and by being close to the consumer’s experience in everyday life and/or familiar to the participants’ picture of meat production. It is also important that the strategy does not alter the quality of the end-product (meat) in an unfavourable way. The implications of the results and the inherent dilemma for meat safety policy formation are discussed.     

Food safety recall effects across meat products and regions

Food safety is one of the key issues for the international meat market. As a major meat exporter, few things facing the U.S. meat industry in recent years have garnered more attention than food safety events and policies. The impacts of Food Safety Inspection Services (FSIS) recalls on United States consumer meat demand are estimated using monthly grocery-scanner data identifying effects across products, geographic regions, and recall type. Results suggest beef E. coli recalls significantly reduce the demand for recalled ground beef contemporaneously among most, but not all, regions in the United States. Evidence of heterogeneity in demand impacts across regions and products is provided for the first time. Domestic and international implications for policy makers, industry leaders, and researchers are discussed.
