The Transition to Modern Agriculture: Contract Farming in Developing Economies

Abstract: Recent years have seen considerable interest in the impact of contract farming on farmers in developing countries, motivated out of belief that contract farming spurs transition to modern agriculture. In this article, we provide a thorough review of the empirical literature on contract farming in bo

Chinese Consumers' Demand for Food Safety Attributes: A Push for Government and Industry Regulations

Abstract: The diet of urban Chinese consumers has changed drastically over the past twenty years, due in part to rising incomes and changing lifestyles. Food consumption has shifted away from grains and toward higher-quality calories from animal proteins and aquaculture products. Dairy demand in urban China has shown remarkable growth in the past decade, driven by mutually reinforcing factors, including rising incomes, government promotion of dairy products, changing urban lifestyles, and the development of more sophisticated marketing channels (Fuller et al. 2006). China’s dairy production has surged from just over 10 million metric tons in 2001 to an expected production level of nearly 48 million metric tons by 2013 (Woolsey, Zhang, and Zhang 2010). Most notable has been the rise in demand for ultra-high temperature (UHT) pasteurized fluid milk among urban consumers in recent years, with a 50% sales increase in 2009 alone (Fuller et al. 2006; Wang, Mao, and Gale 2008; Woolsey, Zhang, and Zhang 2010).

The Effects of Crop Yield Insurance Designs on Farmer Participation and Welfare

Abstract: The performance of individual farm yield and area yield crop insurance programs is evaluated for a representative Iowa corn farm using numerical optimization of expected utility and simulation techniques. Several different contract design features are studied, including the nature of the yield index which triggers insurance payouts, alternative restrictions on coverage levels, and alternative pricing structures. Performance is evaluated in terms of impacts on farmer participation and welfare and is examined in a portfolio setting where futures and options are also available to farmers. The relative performance of different crop insurance designs is found to be particularly sensitive to restrictions on coverage levels, the size of premium loadings, and the degree to which individual farm yields are correlated with area yields.

The impact of online grocery shopping on stockpile behavior in Covid-19

Abstract: This research is to examine the impact of online channels on food stockpile behavior.,In this study, we use bivariate probit models to empirically investigate the impact of online purchasing channels on Chinese urban consumer food hoarding behaviors with random survey samples.,Results show that fresh food e-commerce channels are more likely to be associated with panic stockpile behaviors due to higher likelihood of supply shortages than offline channels with government assistance in logistic management. In contrast, community group buy, another format of e-commerce, appears superior in satisfying the consumer needs and easing the panic buying perception.,It suggests that online channels may have diverse impacts on consumers' panic stockpiling behaviors during the extreme situations. Online channels need to develop efficient supply chains to be more resilient to extreme situations and the government shall recognize the increasing share of the online channels together with traditional offline channels when implementing supporting policies.,With ever increasing share of online channels, it is imperative in terms of policy implications to understand how would online channels affect hoarding behavior.,We are the first study in online shopping's impact on food stockpile during pandemics using a random sample. Although food stockpile behavior at times of emergency have been investigated in many literature, there are no empirical studies on the impact of online channels on stockpile behaviors under extreme situations. Unlike disasters that immediately impact every entity in supply chains covering producers, vendors, distribution centers and retailers, pandemics did not render supply chains affected immediately, but rather increase consumers' willingness to shop online to avoid virus. Thus, Covid-19 provides a natural experiment to investigate the online channels' impact on stockpile behavior.

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

Abstract: 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.

Adaptation options in agriculture to climate change: a typology

Abstract: 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.

The Gift Relationship: From Human Blood to Social Policy

Abstract: 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
