The authors examine the implications of electronic shopping for consumers, retailers, and manufacturers. They assume that near-term technological developments will offer consumers unparalleled opportunities to locate and compare product offerings. They examine these advantages as a function of typical consumer goals and the types of products and services being sought and offer conclusions regarding consumer incentives and disincentives to purchase through interactive home shopping vis-à-vis traditional retail formats. The authors discuss implications for industry structure as they pertain to competition among retailers, competition among manufacturers, and retailer-manufacturer relationships.

Interactive home shopping: Consumer, retailer, and manufacturer incentives to participate in

Adaptation in agriculture to climate change is important for impact andvulnerability assessment and for the development of climate change policy. A wide variety of adaptation options has been proposed as having thepotential to reduce vulnerability of agricultural systems to risks related toclimate change, often in an ad hoc fashion. This paper develops atypology of adaptation to systematically classify and characterize agriculturaladaptation options to climate change, drawing primarily on the Canadiansituation. In particular, it differentiates adaptation options in agricultureaccording to the involvement of different agents (producers, industries,governments); the intent, timing and duration of employment of theadaptation; the form and type of the adaptive measure; and the relationshipto processes already in place to cope with risks associated with climatestresses. A synthesis of research on adaptation options in Canadianagriculture identifies four main categories: (i) technological developments,(ii) government programs and insurance, (iii) farm production practices,and (iv) farm financial management. In addition to these `directadaptations', there are options, particularly information provision, that maystimulate adaptation initiatives. The results reveal that most adaptationoptions are modifications to on-going farm practices and public policydecision-making processes with respect to a suite of changing climatic(including variability and extremes) and non-climatic conditions (political,economic and social). For progress on implementing adaptations to climatechange in agriculture there is a need to better understand the relationshipbetween potential adaptation options and existing farm-level andgovernment decision-making processes and risk management frameworks.

Adaptation options in agriculture to climate change: a typology

Professor Titmuss, an eminent English social theorist, believes that man is inherently altruistic and that the duty of government is to create that social and economic climate which best channels man's drive to work together for the common good. In support of this belief, he has written a book about the procurement, distribution, and transfusion of human blood, a medical topic which he employs as an illustrative social and economic microcosm. The conclusion he reaches is foregone: "The voluntary socialized system in Britain is economically, professionally, administratively and qualitatively more efficient than the mixed, commercialized, and individualistic American system" (Titmuss, R.M: "Why Give to Strangers?" Lancet 1 :123-125, 1971). As the book was written with a bias, so will it be read with bias. My own bias is that of an American and a blood-banker. I am only too conscious of many deficiencies in the American complex of arrangements—it isn't

Making sense of the "clean label" trends: A review of consumer food choice behavior and discussion of industry implications.

Food safety issues often arise from problems of asymmetric information between consumers and suppliers of food with regards to product-specific attributes or characteristics. Food safety concerns in China are having a drastic impact on consumer behavior, commodity markets, international trade and food security. An additional challenge to the problem of asymmetric information lies in the inherent structure of the governing bodies which oversee food safety and quality. Unlike the United States and other developed countries, China’s food safety is regulated by several government entities with different and sometimes overlapping responsibilities. As a result consumers don’t have a comprehensive food safety and quality system on which to base their economic decisions. In an effort to maintain the food supply of the world’s largest economy safe, China’s government has approved a series of tougher food safety laws and regulations. Although publicized as a tough approach to food safety, it is unclear whether this latest effort will make China’s food safer to eat and improve the country’s image to its agricultural trading partners. While much attention has focused on the problems plaguing China’s food inspection system, little research has been dedicated to analyze consumers’ concerns over food safety. In this paper we measure consumer preferences for select food safety attributes in milk. More specifically we estimate consumer’s willingness to pay for government certification, an independent (third party) certification program, national brand, and a product’s shelf-life using a choice experiment approach. We compare and contrast several modeling strategies to capture heterogeneity of consumer preferences. The data used in this study was collected from a choice experiment administered in seven major metropolitan cities in China, yielding a statistical sample of 6,720 observations. Our results suggest that Chinese consumers have the highest willingness-to-pay for a government certification program, followed by national brand, private certification, and longer shelf-life products. We find that Chinese consumers are very concerned about the safety of the milk they purchase and are willing to pay a high premium to assure that their food is safe. The high level of concern regarding milk safety is linked to recent food safety incidents involving dairy products, most notably the Melamine-adulterated milk products. Heterogeneity of consumer preferences and willingness to pay for the select food safety attributes was found by implementing a latent class logit model based on attitudinal responses as well as a mixed logit model. Although it might appear that Chinese consumers’ confidence on the government is eroding, as reported in the wake of recent food safety scandals, our research found that consumers were less confident on non-government food safety control measures. This result indicates that there is a strong need for the Chinese government to provide adequate food safety and quality control. Our findings call upon the direct involvement of the Chinese government in the food safety system. A more strict monitoring system via certification is necessary. If realized, such government efforts will provide higher welfare to consumers in the short-run and will restore consumers’ trust increasing social welfare in the long run. Policy implications of our results are discussed with particular attention given to food safety and security issues.

Got (Safe) Milk? Chinese Consumers' Valuation for Select Food Safety Attributes

The perspective of meat and meat-alternative consumption in China.

Consumer food waste linked to restaurants and canteens has been a long-standing serious problem in China, which hungers for an effective solution. Although government and media have launched campaigns against food waste, limited information on consumer perceptions is provided in helping to guide campaign programs. The influence of perception associated with low food waste is lacking, along with targeting campaigns based on these perceptions. This research aims to fill this gap. The purpose of this paper is to identify consumption perceptions about food waste in the Chinese urban restaurant sector, so that they can be used in social marketing to promote food waste reduction behaviors. Employing Probit models using survey data collected, we found that food security and environmental perceptions are associated with low food waste. Campaigns directed toward reducing food waste should target raising awareness of food security alert and environmental concerns that are more generally appealing to altruistic spirits.

Which Consumer Perceptions Should Be Used in Food Waste Reduction Campaigns: Food Security, Food Safety or Environmental Concerns?

Purpose – The purpose of this paper is to provide a big picture of the current context of Chinese economy, the government policies on agriculture, and the role of agricultural risks and risk management against this background.Design/methodology/approach – The new Chinese economic challenges are laid out upfront. Relevant agricultural issues are then provided, with statistics; next, risks and risk management topics are introduced and controversial issues in agriculture are discussed. Relevant policies reflected in the State Council's No. 1 documents in both 2012 and 2013 are introduced and filled in each section.Findings – The Chinese economy may slow down after decades of fast development. Food security is still a top priority, even with the income rise. Increased labor cost may transform Chinese agriculture from the traditional labor intensive field management into a modern agriculture characterized by high input use and larger scale.Research limitations/implications – The research implication is directi...

Agricultural risks and risk management in the current context of Chinese economy

Chinese agriculture is experiencing a transition from smallholder farming to the emergence of commercial farms that are characterized by intensification and specialization in production, as well as commercialization and cooperation in management. It requires substantial capital to facilitate such a transition, but it is very difficult for farmers in China to access bank credit. One way that commercial farms have to overcome such handicap is by organizing themselves into cooperatives. To assess the effect of cooperatives on the credit accessibility of commercial farms, we have developed a theoretical model as well as an empirical study of commercial farms in Jiangsu Province based on data from a survey of 754 commercial farm owners. Instrumental variable (IV) methods and the Propensity Score Matching (PSM) method that control endogeneity problem are used in the analysis. The empirical results show that cooperatives have a significant positive impact on the credit access of commercial farms. Commercial farms participating in cooperatives may alleviated their credit constraints by about 17.3 percentage points and increase the average credit per capita by nearly 80,000 Yuan. Cooperatives improve the credit access of commercial farms by exerting strong market power and reputation effect based on its organizational advantages. A disaggregated analysis also reveals that small commercial farms tend to benefit more from cooperatives in improving credit access than large commercial farms. L'agriculture chinoise connaît une transition de l'agriculture paysanne à l'émergence d'exploitations commerciales qui se caractérisent par l'intensification et la spécialisation de la production, ainsi que la commercialisation et la coopération dans la gestion. Il faut des capitaux importants pour faciliter une telle transition, mais il est très difficile pour les agriculteurs chinois d'accéder au crédit bancaire. L'une des façons dont les exploitations agricoles commerciales doivent surmonter ce handicap est de s'organiser en coopératives. Pour évaluer l'effet des coopératives sur l'accessibilité au crédit des fermes commerciales, nous avons développé un modèle théorique ainsi qu'une étude empirique des fermes commerciales dans la province du Jiangsu basée sur les données d'une enquête auprès de 754 propriétaires de fermes commerciales. Les méthodes des variables instrumentales et la méthode ACP qui contrôlent le problème d'endogénéité sont utilisées dans l'analyse. Les résultats empiriques montrent que les coopératives ont un impact positif significatif sur l'accès au crédit des exploitations commerciales. Les fermes commerciales participant aux coopératives peuvent alléger leurs contraintes de crédit d'environ 17,3 points de pourcentage et augmenter le crédit moyen par habitant de près de 80 000 yuans. Les coopératives améliorent l'accès au crédit des exploitations agricoles commerciales en exerçant un fort pouvoir de marché et un effet de réputation basé sur ses avantages organisationnels. Une analyse désagrégée révèle également que les petites exploitations commerciales ont tendance à bénéficier davantage des coopératives pour améliorer l'accès au crédit que les grandes exploitations commerciales.
