Effects of media headlines on consumer preferences for food safety,quality and environmental attributes

In recent years, Asia has emerged as an important supplier of food to Western countries. In this study, we focus on shrimp, a major aquaculture commodity, to evaluate consumer willingness‐to‐pay (WTP) for enhanced food safety, use of antibiotics and eco‐friendly practices used in producing shrimp in the presence of country‐of‐origin labelling. Specifically, this research assesses the effects of news headlines regarding product safety, as information shocks on U.S. consumer demand. Consumers were found to have a mean willingness‐to‐pay of $7.81 per pound of shrimp with an enhanced safety characteristic from the United States, $0.94 for the same type of shrimp from China and $2.43 for similar shrimp from Thailand. Consumers had a WTP for the absence of antibiotics in the production of U.S. shrimp of $7.31 and were only willing to pay for an eco‐friendly attribute on domestically produced shrimp. Media headlines were found to have a statistically significant effect on consumer preferences and WTP for product characteristics. Food policy and international agribusiness implications of our findings are discussed.     

Acceptance of genetically modified food: comparing consumer perspectives in the United States and South Korea

This study examines public perceptions of biotechnology, specifically the consumer approval of genetically modified food products, from plant as well as from animal origin, based on data collected from national surveys conducted in both the United States and South Korea. South Korean consumers reported better understanding of food production, science, and technology relative to U.S. consumers. South Korean consumers also recalled having heard more about genetic modification than did U.S. consumers. Findings also suggest that consumers in the United States and South Korea who possessed an accurate knowledge of the applications and outcomes of genetic modification technology were more likely to approve of its use for the creation of foods than those who had inaccurate or no knowledge of the technology. Results also indicate that consumers who considered labeling of genetically modified foods to be necessary are less likely to approve of the genetic modification of foods than those who did not. Consumers in both countries are less approving of genetic modification of animals than the genetic modification of plants. However, U.S. consumers are more approving of using genetic modification technology to create animal‐derived foods than are South Korean consumers.     

Heterogeneous consumers and differentiated food markets: Implications for quality signaling in food supply chains

The Fellow's address begins by noting several recent consumer food trends and the changing way in which we perceive value-added. I then focus on the topic of heterogeneity in consumer behavior, reviewing contributions from the literature that enhance our ability as economists to model and measure heterogeneity. Supply chain responses to consumer heterogeneity are examined, including a discussion of information flows within supply chains and the role of certification and verification. I close with a consideration of policy implications flowing from consumer heterogeneity.     

Regional Price Effects of Extreme Weather Events and Wheat Export Controls in Russia and Ukraine

We build on the price transmission framework to identify domestic wheat price effects of wheat export controls. We explicitly take into account that a harvest failure causes domestic price effects. Moreover, the analysis at the regional level provides further evidence of the functioning of export controls in a large country. Results suggest a pronounced regional heterogeneity in the strength of domestic price effects of the 2010/11 export ban in Russia. The wheat price dampening effects amount to up to 67% and are strongest in the major wheat exporting region with direct access to the world market. This effect is transmitted to other regions by increased and reversed interregional trade flows. In contrast, we find that regional variation of export controls’ domestic price effects in Ukraine is rather small.     

Rural Adaptation in Russia: Who Responds and How Do We Measure It?

Utilizing survey data from 800 households in five regions of Russia, this article attempts to measure adaptation to reform stimuli according to socio-economic strata. While the orthodox literature has emphasized rural resistance to reform, in fact one of the main analytical obstacles is differentiating between adaptive and survival strategies. Time horizon is used as the primary criterion to distinguish between adaptive and survival behaviour. The article analyses adaptive responses by examining the use of rural credit, the operation of a household business, the enlargement of household land plots and a set of attitudes that taken together comprise an 'entrepreneurial spirit'.     

Food commodity price changes and consumer welfare in Bangladesh: Valuable lessons for today

The recent rise in global food prices threatens many countries worldwide, especially the vulnerable populations. Viable coping strategies can only be designed based on the important policy lessons learned from the experiences of these countries in confronting the similar shocks of 2007–2011. However, the disproportionate effects of these events and the impacts of policy responses remain largely unexplored. We examine the impact of a food price surge and the effectiveness of various mitigating policies in Bangladesh, one of the most populous, densely populated countries in the world that is plagued by poverty. Specifically, we combine individual-level expenditure survey data with recent advances in consumer theory to examine the welfare consequences across income groups and geographic areas of the country over 2000–2016. Our empirical findings lend support to the hypothesis that the brunt of the price surge was borne by relatively less affluent and rural households, and government poverty alleviation programmes were largely ineffective.

Social protection for people with disabilities in Tanzania: a mixed methods study

People with disabilities are more vulnerable than others to poverty and exclusion from key services, such as health and education. Consequently, they particularly need social protection, yet may have difficulties accessing these programmes. This study aims to assess the need for, and inclusion in, social protection programmes among people with disabilities compared to those without, in three districts in Tanzania. Using a mixed methods approach, our study finds that although the need for social protection programmes was higher among people with disabilities compared to the general population, this was not matched by higher enrolment. People with disabilities were aware of social protection programmes in their area but were not targeted specifically, and benefit packages offered by the programmes were not adapted to their needs. Modifying mainstream social protection schemes to be inclusive of people with disabilities may therefore be an important step towards addressing poverty alleviation goals, including those set out in the recently adopted sustainable development goals (Goal 1, target 3).

Removing border protection on wheat and rice: effects on rural income and food self‐sufficiency in China*

In this paper, I use the Monash Multi‐Country model – a dynamic Computable General Equilibrium model of China, Australia and the Rest of the World – to analyse the effects of removing border protection on wheat and rice in China. The analysis points to the possibility that removing border protection on wheat and rice may lead to an increase in rural income in China. This is mainly due to the following two factors. First, removing border protection on wheat and rice not only leads to a contraction in agricultural activities, but also leads to an expansion in manufacturing and services activities. Second, on average, rural households in China obtain over half of their income from manufacturing and services activities.     

Agriculture and land use: Demand for and supply of agricultural commodities,characteristics of the farming and food industries,and implications for land use in the UK

Agriculture is the largest type of land use in the UK, accounting for about 77 per cent of the total area, compared with an average 50 per cent for the EU27. But in common with most high-income countries, agriculture's contribution to UK GDP and employment is low, at about 0.5 and 1.8 per cent, respectively, although the regional importance of the sector (and its associated food and farming industries) varies considerably.Of the 17.5 million ha used for agriculture, about 28 per cent is allocated to crops, and 67 per cent is grassland. The grassland includes 4.4 million ha of sole-owned rough grazing and 1.1 million ha of common land in mainly upland “disadvantaged areas,” primarily used for beef and sheep production. This has a major influence on land use, especially in the northern and western parts of the UK.From the 1930s until the mid-1980s, UK policy promoted increases in agricultural productivity to feed the nation from its own resources. An array of income and production support measures encouraged intensive farming, including a relative switch to arable farming in eastern areas. Since the early-1990s, policies have sought simultaneously to make UK agriculture internationally competitive and environmentally benign. These policies, evident in the Agenda 2000 Reforms of the Common Agricultural Policy, point the way forward for the future. It is likely that a greater distinction will emerge between policies to protect natural resources and enhance the flow of non-market ecosystem services from rural land, and agriculture and food policies intended to encourage an appropriate proportion of national food requirements to be met from domestic sources.It seems likely that over the next 50 years, the UK's land area will be required to deliver an increasingly diverse range of private and public goods to meet growing human needs and aspirations. This will require a balance of policy-driven goals and market forces. It will also need a much improved understanding of the trade-offs between food production and environmental goals and of the institutional arrangements required to achieve a balance of economic, social and environmental outcomes.

Alternative farming and collective goals: Towards a powerful relationships for future food policies

Based on the significant amount of literature on the concept of spatial, ecological, and social embeddedness in the Alternative Food Networks (AFNs) research, this study describes the main dynamics related to the involvement of non-conventional farmers in their collective ideas and actions.With a comparison between two European regions: Sardinia and the Community of Madrid, the paper identifies different styles of behaviour among organic producers, whether or not supervised by a control body, and highlights the differences and similarities regarding their ideas about how alternative agriculture has an impact on the environment as well as society. Eco-economies and ecopreneurship are also considered. The aim is to see if, and to what extent, these ideas have a collective character, going beyond the limits of the single farm to reach a regional scale and, thus, if there is a basis for the development of future food-related planning policies. Through the information provided by semi-structured interviews, farmers have been divided into categories according to their degree of embeddedness, described through the main themes that emerged during the interviews. Every farmer has been included in only one category according to his or her main preference, which does not imply the ab-sence of a positive attitude towards other categories.The study aims to contribute to the understanding of how AFN values and methods can boost the improvement of biodiversity and landscape conservation through collective actions which have the power to boost and develop rural initiative at a regional scale.     

Social protection for people with disabilities in Africa and Asia: a review of programmes for low- and middle-income countries

Despite a greater need for social protection among people with disabilities, there is limited evidence of their inclusion into social protection programmes in low- and middle-income countries. This paper presents the findings from a review of regional and global data sources for Asia-Pacific and Africa to identify social protection programmes that aim to include people with disabilities. It finds a substantial number of programmes in both regions, although there is considerable variation in the quantity and types of programmes within and between regions and countries, as well as between low- and middle-income countries. Further, the quality of data is not sufficient to assess the degree to which these programmes are genuinely inclusive of people with disabilities. As such, it highlights important limitations in the way data is currently being collected that require further attention in the context of the Sustainable Development Goals and the commitment to ‘Leave No-one Behind’     

Disability and social protection programmes in low- and middle-income countries: a systematic review

This paper systematically reviews the evidence on whether persons with disabilities in low- and middle-income countries are adequately included in social protection programmes, and assesses the financial and non-financial impacts of participation. Overall, we found that access to social protection appears to fall far below need. Benefits from participation are mostly limited to maintaining minimum living standards and do not appear to fulfil the potential of long-term individual and societal social and economic development. However, the most notable finding of this review is that there is a dearth of high-quality, robust evidence in this area, indicating a need for further research.
