农产品价格非对称传递现象时有发生,农产品的易腐特性是导致这一现象的重要原因之一.我们以果蔬产品中的苹果、香蕉、土豆和西红柿四种易腐程度不同的产品为例,采用时间序列的计量模型,来分析易腐程度与纵向关联市场间的价格传递关系.研究结果表明,越是易腐的农产品,其价格传递的非对称性越明显;越是耐储存的农产品,其价格传递的非对称性越微弱. 相似文献

Fat taxes and thin subsidies: Prices, diet, and health outcomes 总被引:1,自引:0,他引:1

“Fat taxes” have been proposed as a way of addressing food-related health concerns. In this paper, we investigate the possible effects of “thin subsidies”, consumption subsidies for healthier foods. Empirical simulations, based on data from the Continuing Study of Food Intake by Individuals, are used to calculate the potential health benefits of subsidies on certain classes of fruits and vegetables in the United States. Estimates of the cost per statistical life saved through such subsidies compare favorably with existing U.S. government programs. 相似文献

Small producers,supermarkets, and the role of intermediaries in Turkey's fresh fruit and vegetable market 总被引:1,自引:0,他引:1
A wide range of empirical studies show the extent to which the rise of supermarkets in developing countries transforms domestic marketing channels. In many countries, the exclusion of small producers from so‐called dynamic marketing channels (that is, remunerative ones) has become a concern. Based on data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that intermediaries are important to understanding the impact of downstream restructuring (supermarkets) on upstream decisions (producers). Results show first that producers are not aware of the final buyer of their produce, because intermediaries hinder the visibility of the marketing channel, thereby restricting a producer's choice to that of the first intermediary. Econometric results show that producers who are indirectly linked to the supermarkets are more sensitive to their requirements in terms of quality and packaging than to the price premia compensating the effort made to meet standards. Therefore, the results lead us to question the role of the wholesale market agents who act as a buffer in the chain and protect small producers from negative shocks, but who stop positive shocks as well, and thereby reduce incentives. 相似文献

The Internet is a growing information and communication channel for health- and diet-related issues. Keeping updated on the fruit- and vegetable-related (F&V) discourses among laypeople is important for health communicators in order to promote F&V consumption through tailored health messages. The aim of the present study was to identify F&V-related discourses in weblogs that were maintained, obviously, to influence diet. A theoretically chosen sample of weblogs were analysed applying critical discourse analysis. The analysis showed three partly overlapping F&V-related discourses: (1) normative consumption with a focus on single nutrients and physiological mechanisms; (2) authentic consumption with a desire for naturalness; and (3) altruistic consumption where ethical responsibilities are enhanced. Bloggers have clear perceptions on ideal F&V consumption, but it is a challenge for the reader to make a synthesis of the discourses presented. Filtering contradictory instructions requires health literacy, which may need more support from dietetic professionals. 相似文献

本文在简介英国农业发展和蔬菜供求特点的基础上,利用蔬菜进出口数量、金额、出口均价以及进口率等指标,分别从中国出口蔬菜和英国进口蔬菜的角度,对两国蔬菜贸易特征进行实证研究,据此提出中国深入开拓英国乃至欧盟蔬菜市场的主要建议蔬菜出口企业应注重提高产品质量;在出口市场定位上考虑发挥中国蔬菜的差异化竞争优势。同时,政府应为蔬菜出口企业提供相应的信息和政策支持等服务。 相似文献

Disruptive layouts, smart carts, suggestive signage, GPS alerts, and touch-screen preordering all foreshadow an evolution in how healthy foods will be sold in grocery stores. Although seemingly unrelated, they will all influence sales by altering either how convenient, attractive, or normal (CAN) it is to purchase a healthy target food. A Retail Intervention Matrix shows how a retailer’s actions in these three areas can be redirected to target shoppers based on whether the shoppers are Health Vigilant, Health Predisposed, or Health Disinterested. For researchers, this review offers an organizing framework that integrates marketing, nutrition, psychology, public health, and behavioral economics to identify next generation research. For managers, this framework underscores how dozens of small, low cost, in-store changes are available to each that can surprisingly increase sales of entire categories of healthy food. 相似文献

The article assesses the stabilization effects of the EU import regime for fresh fruit and vegetables based on the entry price system (EPS). The analysis is carried out on the EU prices of tomatoes and lemons and those of imports from some of the main competing countries on the EU domestic markets: Morocco, Argentina, and Turkey. It is based on the estimation of a threshold vector autoregressive econometric model that is shown capable of taking the workings of the import regime into account. The model shows that prices behave differently when import prices are above/below the trigger entry price. This article allowed to highlight the cases for which the isolation effect of EPS seems reached and the resulting stabilization effects. 相似文献

Only a small number of works in the literature examines the role of familiarity in the perception of products from a specific origin, despite the importance of this variable in the formation of product image and its effects on consumer behavior. The current work aims to fill this gap in the literature by carrying out a cross-national analysis of consumers' image of fruit and vegetables that includes a defined origin. For this purpose, the authors examine the influence of product cues on the formation of a global image of the product, and considers the moderating role of familiarity in this relation. The results indicate that product familiarity has an effect on the relation between the product cues and the image perceived by the consumer, and that differences exist between the nationalities considered. 相似文献

African indigenous vegetables (AIVs) have been part of the food systems in sub-Saharan Africa for generations. The region is a natural habitat for more than 45,000 species of plants, of which about 1,000 can be eaten as green leafy or fruit vegetables that happen to be the mainstay of traditional diets. During the colonial era, adventurers and slavers sailing in Africa introduced exotic plants such as maize, cassava and beans and, later, commercial crops such as sugarcane, cocoa, coffee and cotton, which began contributing more to life. Farmers integrated these crops into their age-old livelihood strategies at the expense of traditional subsistence crops. AIVs were almost entirely neglected and considered ‘poor people's' plants. To reverse the trend, FARM-Africa and its partners reintroduced AIVs which are now forming part of families’ diets as well as becoming a source of income for smallholder farmers in Arumeru, Tanzania and Kiambu, Kenya. AIVs are robust and productive, and thus well suited to feeding the hungriest and most vulnerable sections of society. 相似文献
