我国贫困农村家庭食物安全状况及影响因素的实证研究

本文在深入分析食物安全、家庭食物安全内涵的基础上，利用12个国家挟贫重点县的农户调查资料，通过构建指标体系对我国贫困农村的家庭食物安全水平和程度进行衡量和评价，并对其影响因素进行了分析，结果表明：近20多年来，我国贫困农村地区的家庭食物安全水平不断提高，食物安全广度不断扩大，但是食物安全深度却出现下降；食物获得能力对家庭食物安全具有显著的正影响，提高贫困农村地区居民的收入水平和家庭粮食自给能力有助于降低家庭的食物不安全发生概率；食物可获得性对家庭食物安全具有非常显著的正影响，市场方便度越高，实现家庭食物安全的概率越高；家庭规模和家庭结构对家庭食物安全具有显著影响，随着家庭规模、家庭结构复杂程度和家庭温饱负担程度的提高，农户面临的食物不安全风险的概率也在增加。     

Top shelf foods and drinks: Female adolescents' eating motives, constraints and behaviours during the school day

This paper reports the findings of a study on female adolescents' food choice motives, constraints and behaviours over the course of the school day. A model of top shelf food and drink (TSFD) consumption is developed. TSFDs relate to those foods located towards the top of the food pyramid as presented in the current Irish guide to healthy eating and are advised to be consumed in very small amounts or used sparingly. The findings support negative associations between TSFD consumption and the importance of health/physique, diet/slimming and natural ingredients to the adolescent. Perceived guardians' knowledge of adolescents' eating behaviour was also found to be negatively related to the frequency of TSFD consumption. Positive associations with TSFD consumption are found with regards to the availability of these foods in school, and price and trendiness motives. The provision of lunch money was found to be positively associated with availability of food in schools.     

Consideration Set:

Consideration set studies have been confined to consumer goods purchases under the developed country context. This research studied the consideration set during agricultural input purchase under a developing country context. Though a farmer-consumer is assumed to be lacking the knowledge to form the consideration sets, the results show that these buyers form consideration sets similar to those under the consumer goods buying situations in the developed countries and these were influenced positively by the economic risk and negatively by the level of education.     

Horticultural Auctions in the Netherlands

This paper depicts the evolution of Dutch auctions during the past hundred years from a "price discovery" institution to a "marketing" institution, focusing on price discovery. A conceptual framework is proposed to assess the suitablility of marketing management by agricultural marketing institutions. The history of Dutch horticultural auctions is briefly reviewed. The conceptual framework proposed is applied to the evolution of Dutch horticultural auctions.     

Slotting Fees for Organic Retail Products: Evidence From a Survey of U.S. Food Retailers

Based on a survey of U.S. food retailers, our study finds that almost one third of U.S. food retailers charge slotting fees for certified organic food products, a retailing area where slotting fees had not previously been well documented. Econometric results from both ordered response and binary response models suggest that a number of firm-level attributes do influence the presence and/or relative size of organic slotting fees in a manner that is mostly consistent with an economic efficiency rationale and partly consistent with a market power/strategic behavior rationale for slotting fees.

Organic‐ and Animal Welfare‐labelled Eggs: Competing for the Same Consumers?

To understand the market for sustainable foods, it is important to allow for heterogeneous preferences. However, most studies of consumer preferences for sustainable foods only investigate average consumer preferences. They do not take into account that some consumer segments attempt to purchase as much sustainable food as possible, others are almost indifferent to the notion of sustainable food, and still others consider sustainable food a complete hoax. The aim of this study is to explore the preferences for various types of premium eggs across three consumer segments. We conduct a choice experiment including 900 Norwegian consumers and perform a behavioural segmentation based on the frequency of organic food purchase. We find that the segment purchasing the most organic food is, as expected, willing to pay a significant premium for organic eggs over eggs displaying only enhanced animal welfare. However, most consumers, who only occasionally purchase organic products, are unwilling to pay more for organic eggs than for enhanced animal welfare eggs, suggesting diminishing marginal utility for additional attributes. We find that a third consumer segment attempts to avoid organic eggs, even when they cost the same as other eggs. Our findings suggest that organic products will be unsuccessful in acquiring a larger share of the market as long as most consumers are unwilling to pay a premium for organic products with all their cost increasing sustainable attributes over products that have only a single sustainable attribute, in our case enhanced animal welfare.     

Winners and losers from food industry policy: An application to Danish food industry firms

Policy impacts on food industry firms are investigated. A new approach is presented for the analysis of food industry policies that focuses on food industry firms. Data from a survey of Danish firms in 2003-2004 are used to define and construct tables of winners and losers from 30 regulatory areas. Two forms of statistical test are employed in a grid-search to identify association between regulatory areas, types of firms, and patterns of winning and losing. Results indicate that the type of firm, rather than the policy instrument, determines patterns of winning and losing. Upstream and downstream ownership of assets by food industry firms, and their trade orientation, are shown to be the most important variables. For several policy areas the pattern of winning and losing is found not to be associated with any specific firm types, which indicates that their impact is neutral across all types of firms studied. Firm size was found to be poorly associated with firms' capacity to win and lose from several policies involving high-investment compliance.     

Weather Risk, Wages in Kind, and the Off-Farm Labor Supply of Agricultural Households in a Developing Country

This article investigates the effects of weather risk on the off-farm labor supply of agricultural households in a developing country, distinguishing different types of off-farm labor markets. A multivariate two-limit tobit model is applied to data from India. The regression results show that the share of the off-farm labor supply increases with weather risk, the increase is much larger in the case of nonagricultural work than in the case of agricultural wage work, and the increase is much larger in the case of agricultural wages paid in kind than in the cash wage case, suggesting farmers' considerations of food security.     

Consumer preferences for domestic and organically labelled vegetables in Sweden

The aim of our research is to examine Swedish consumers' perception and preferences of domestic vegetables compared to on the one hand imported and on the other hand organically grown vegetables. The paper draws from two consumer studies. The first study is a text analysis of consumers' associations to the four concepts Swedish, imported, organic and conventional vegetables as well as a conjoint analysis of the relative importance of the same four characteristics in the case of carrots. The second study is a taste experiment on tomatoes from the same Swedish grower labelled in three different ways, as Swedish, Dutch or organic. The conjoint analysis indicates that Swedish origin is considered more important than organic production methods. The text analysis shows that Swedish is associated with positive values, for instance, high quality, while imports have a more negative image. Organic is associated with characteristics such as being non-toxic, good quality and expensive while conventional is associated with poison, being good enough and traditional. The preference for Swedish vegetables is supported by the taste study. Tomatoes that were labelled as Swedish or organic were perceived as tastier than tomatoes labelled as Dutch. Thus, the experience of taste seems to be affected by the labelling. The conclusion is that to many Swedish consumers “Swedish is good enough” as a quality criterion. However, the research situation differs from a real shopping environment, where consumers make choices between bundles of different attributes, not only provenance and production method. Moreover, in a real shopping situation supermarkets promote their own private brands, regardless of origin, thus make origin less accentuated.
