3 pages, via online journal, Agriculture is the backbone of most developing economies and structural transformation an important vehicle for economic development in low-income agrarian contexts. This special issue brings together a set of high quality academic studies to answer key research questions of importance to understanding agricultural development and change in developing country settings. Using the case of Vietnam, this collection provides comprehensive analytical contributions, that rely on detailed microdata, to understand crucial topics within the fields of agricultural and development economics. Together, these studies provide important insights into the mechanisms underlying structural transformation and its consequences that can contribute to the design of policies to manage the structural transformation process effectively, particularly for the most vulnerable groups in society.
16 pages, via online journal, We examine important changes in agriculture in Vietnam in the context of ongoing structural changes in the economy. We use a household-level panel dataset and a quantitative framework to document the extent and consequences of factor misallocation in agriculture during the period between 2006 and 2016. Despite rapid growth in agricultural productivity and a reallocation of factor inputs to more productive farmers, we find that misallocation across farmers remains high and increased during the period. Reallocation of factor inputs has not been strong enough to accommodate substantial changes in farm productivity over time. Our analysis also reveals important differences between the north and south regions.
14 pages, via online journal, We combine nationally representative household and labor force survey data from 1992 to 2016 to provide a detailed description of rural labor market evolution and how it relates to the structural transformation of rural Vietnam, especially within the agricultural sector. Our study adds to the emerging literature on structural transformation in low-income countries using micro-level data and helps to answer several policy-related questions. We find limited employment creation potential of agriculture, especially for youth. Rural-urban real wage convergence has gone hand-in-hand with increased diversification of the rural economy into the non-farm sector nationwide and rapid advances in educational attainment in all sectors’ and regions’ workforce. Minimum wage laws seem to have played no significant role in increasing agricultural wages. This enhanced integration also manifests in steady attenuation of the longstanding inverse farm size-yield relationship. Farming has remained securely household-based and the family farmland distribution has remained largely unchanged. Small farm sizes have not obstructed mechanization nor the uptake of labor-saving pesticides, consistent with factor substitution induced by rising real wage rates. As rural households rely more heavily on the labor market, human capital accumulation (rather than land endowments) have become the key correlate of improvements in rural household well-being.
8 pages, Does it matter whether farmers receive advice on pest management strategies from public or from private (pesticide company affiliated) extension services? We use survey data from 733 Swiss fruit growers who are currently contending with an infestation by an invasive pest, the fruit fly Drosophila Suzukii. We find that farmers who are advised by public extension services are more likely (+9–10%) to use preventive measures (e.g. nets) while farmers who are advised by private extension services are more likely (+8–9%) to use synthetic insecticides. These results are robust to the inclusion of various covariates, ways to cluster standard errors, and inverse probability weighting. We also show that our results are unlikely to be driven by omitted variable bias. Our findings have implications for the current debates on both the ongoing privatization of agricultural extension and concerns regarding negative environmental and health externalities of pesticide use.
9 pages., Online via UI electronic subscription, Researchers analyzed the effectiveness of the European Union Pledge, a self-regulation initiative of leading food companies at the European level, in restricting television advertising of food and drink products high in fat, sugar or salt to children. Results indicated that effectiveness was limited by the focus on children's program and the relatively lenient nutritional criteria agreed to by signatory companies.
14 pages., Online via UI electronic subscription., Examines the impact of gain and loss message framing and issue involvement elicitation on consumer willingness to pay for two food safety enhancing technologies: cattle vaccines against E. coli and direct-fed microbials. Results showed strong consumer preference and willingness to pay for the technologies and consumer welfare gains from their introduction.
9 pages., Online via UI electronic subscription., A choice experiment was used to evaluate the U.S. public's willingness to pay for egg attributes including housing system, color, size, and certifying agency. A significant difference in willingness to pay for hen housing systems was found using video information treatments describing hen housing systems. Participants were indifferent between hen housing systems when they viewed video treatments describing hen housing systems. However, they clearly preferred the cage-free system when they viewed no video treatments. "Results point towards potential public misunderstanding of the costs and benefits associated with the "cage-free" egg label designation."
8 pages., Online via UI electronic subscription., Researchers measured farmer demand for a new agricultural technology , a triple-layered hermetic storage bag which reduces storage loss from insect pests and neutralizes aflatoxin contamination in grain. Findings revealed a highly elastic demand that that the wholesaler could increase profit by lowering the price. Farmers who had prior awareness of the bag were willing to pay 20% more on average than those previously unaware of it. Farmers' valuation of the bags was not significantly different based on the medium (text, audio, or video) through which they received the information.
16 pages., Via online journal., This paper assesses the effect of transportation and communication networks on farmers’ choice of market channels for paddy and wheat, and subsequently on the prices they receive from these channels. It is found that smallholder farmers sell more to informal channels i.e. local traders and input dealers, and typically receive lower prices from them compared to the government-set minimum support prices (MSP). The prices realized from the sales in regulated markets are also less than the MSP despite these being claimed to be more transparent in price discovery. Econometric results show that farmers’ access to transportation and information enables them to obtain better price terms from informal as well as formal channels. The effect of information is relatively stronger, implying that farmers’ access to transportation itself is not sufficient but is effective when combined with provision of market information. Further, our proposition is that despite a positive impact of the improved market access on price realization from informal traders, farmer-trader relations are unlikely to undergo a meaningful change because of the tied transactions involving inputs, credit and outputs.
15 pages, Food security and agricultural-led industrialisation are pivotal development objectives in Ethiopia. One of the main challenges this country faces is increasing agricultural productivity by integrating smallholder farmers into a high-value agricultural commodity supply chain. This paper examines an integrated project—the Agricultural Value Chains Project in Oromia (AVCPO)—that aims to improve the livelihoods of smallholders in the Bale Zone by involving them in the production of high-quality durum wheat and linking them to the pasta industry via farmers’ cooperatives. Using primary data collected in 2014 and retrospective information, this paper investigates the AVCPO’s effects on the quantity of cereal production, the share of cereals that have been sold through cooperatives, food security, and education. In order to account for potential violations of the exclusion restriction assumption, an instrumental variable approach is applied, together with three additional estimation strategies.
The results suggest that the project has had a large and positive effect on gross and net values of cereal production per hectare, as well as on the share of production sold to pasta makers through cooperatives. These benefits accrue equally to land-rich and land-poor farmers. Furthermore, our analysis suggests that the AVCPO has improved educational outcomes and reduced food insecurity, without affecting crop rotation practices. Overall, our findings point to the effectiveness of the project. Before replicating or scaling up this intervention, however, it is necessary to understand how to better involve poorer farmers and which adjustments are needed if the areas selected have a lower potential than Bale Zone.
22 pages., Online via UI electronic subscription, Researchers combined recent national survey data and media reports to quantitatively examine the effects of food scandals and media exposure on food safety risk. Findings suggesed hat media reported food scandals are not significantly related to public concern about food safety risk, suggesting that food risk perceptions may be nationwide rather than region specific. Findings also suggested that more educated citizens with more media exposure were more concerned about food safety risk.
12 pages., Online via UI electronic subscription, Analysis of five cases of peak social media activity in the Dutch livestock sector. Findings indicated that social media hypes revolved around activism, scandals, and conflicts - each with characteristic patterns of activity, framing, interaction and media interplay. "Our results show the need to adopt a proactive and interactive approach that transcends the view of social media as a mere communication channel to respond in crisis situations."
11 pages., Online via UI electronic subscription, Authors examined ethical issues arising from the collection, management and analysis of data, as well as those faced by researchers as they formulate, fund and disseminate their research. They paid special attention to ethical issues such as data dredging or p-hacking and potential ethical issues arising from interaction with media.
10 pages., Online via UI electronic subscription, Results from analysis of a scale-adjusted stated preference technique (mostly best-worst scaling) showed considerable heterogeneity in consumers' perceptions of trust and choice variability related to use of nanotechnology in food production and packaging. Findings provided insights in the development of risk communication and management.
16 pages., via online journal, The sustainable intensification of animal production systems is increasing as a consequence of increased demand for foods originating from animals. Production diseases are particularly endemic in intensive production systems, and can negatively impact upon farm animal welfare. There is an increasing need to develop policies regarding animal production diseases, sustainable intensification, and animal welfare which incorporate consumer priorities as well as technical assessments of farm animal welfare. Consumers and/or citizens may have concerns about intensive production systems, and whether animal production disease represent a barrier to consumer acceptance of their increased use. There is a considerable body of research focused on consumer willingness-to-pay (WTP) for improved animal welfare. It is not clear how this relates specifically to a preference for reduced animal production disease incidence in animal production systems. A systematic review and meta-analysis were conducted to establish the publics’ WTP for farm animal welfare, with a focus on production diseases which arise in intensive systems. Systematic review methodology combined with data synthesis was applied to integrate existing knowledge regarding consumer WTP for animal welfare, and reduced incidence of animal production diseases. Multiple databases were searched to identify relevant studies. A screening process, using a set of pre-determined inclusion criteria, identified 54 studies, with the strength of evidence and uncertainty for each study being assessed. A random effects meta-analysis was used to explore heterogeneity in relation to a number of factors, with a cumulative meta-analysis conducted to establish changes in WTP over time. The results indicated a small, positive WTP (0.63 standard deviations) for farm animal welfare varying in relation to a number of factors including animal type and region. Socio-demographic characteristics explained the most variation in the data. An evidence gap was highlighted in relation to reduced WTP for specific production diseases associated with the intensification of production, with only 4 of the 54 studies identified being related to this. A combination of market and government based policy solutions appears to be the best solution for improving farm animal welfare standards in the future, enabling the diverse public preferences to be taken into consideration.

19 pages., Online via UI e-subscription., Authors tested food label and information treatment effects on subjects' willingness-to-pay for organic, "natural," and conventional foods. They found large information effects, including asymmetric cross-market effects for natural and organic foods. Organic premiums increased in response to subjects' seeing the "natural" foods industry's perspective on its products.
9 pages., Online via UI electronic subscription, Using a panel selection model, researchers found robust evidence that the 2003 Bovine Spongiform Encephalopathy (BSE) caused a change in the way people viewed and responded to recalls of ground beef, a change (reduction of purchase) that persisted for at least two years.

11 pages., Via UI online subscription, Researchers examined the degree to which factors which determine uptake of personalised nutrition vary between EU countries to better target policies to encourage uptake, and optimise the health benefits of personalised nutrition technology.
9 pages., Online via UI electronic subscription, Researchers reported on their analysis of a case of scandal concerning "set-style yogurt and jelly event" reporting by a micro-blog (i.e., we media) from "opinion leaders." Findings suggested that we media greatly increased dissemination of the voices of "opinion leaders" and triggered large-scale communication of food safety messaging to the public. "We media could be an effective tool to improve the food-safety status of the market."
Online via UI electronic subscription, Researchers used weekly meat production and sales data to assess how media depictions of LFTB affected consumer demand during and after the scare in 2012.
8 pages., Online via UI electronic subscription, Through a questionnaire administered to university students taking food-related courses, researchers found that message framing has an influence on their purchasing intentions related to a food hazard issue. Results further suggested that the effect of framing was related to the respondent's prior knowledge about the issue.
10 pages., Online via UI electronic subscription., Researchers surveyed 423 students enrolled in agriculture, business, and communication design courses at two universities, as well as Facebook users. Responses involving identified food recalls were analyzed using hierarchical regression analysis. Findings indicated that recall concern, propensity to reduce consumption beyond the recall parameters, and media reliance held strong, direct effects on broad consumption changes.
12 pages., Online via UI electronic subscription, Authors developed a composite index of GMO standard restrictiveness for 60 countries, assigning objective scores to six different regulatory dimensions. Results showed that many of the determinants highlighted in the theoretical literature are important determinants of the restrictiveness of the GMO regulation. Findings emphasized the prominent role of the market for information, "showing that the structure of domestic mass media (public vs. private) is an important driver of GMO standards."
7 pages., Via online journal., Policy makers in the European Union are envisioning the introduction of a community farm animal welfare label which would allow consumers to align their consumption habits with their farm animal welfare preferences. For welfare labeling to be viable the market for livestock products produced to higher welfare standards has to be sufficiently segmented with consumers having sufficiently distinct and behaviourally consistent preferences. The present study investigates consumers’ preferences for meat produced to different welfare standards using a hypothetical welfare score. Data is obtained from a contingent valuation study carried out in Britain. The ordered prohbit model was estimated using Bayesian inference to obtain mean willingness to pay. We find decreasing marginal WTP as animal welfare levels increase and that people’s preferences for different levels of farm animal welfare are sufficiently differentiated making the introduction of a la belling scheme in the form of a certified rating system appear feasible.
9 pages., Online via UI electronic subscription, Content analysis of 160 articles from four national U.S. newspapers, the largest regional paper in Iowa, and the Associated Press revealed that the recall was framed both as a failure of government oversight and as an instance of poor production practices by the farmers in question. Particular media focus was given to the U.S. Food Safety Modernization Act and the FDA Egg Rule. Relatively little media attention was given to industrial agriculture as a causal frame or the purchasing of "alternative" eggs as a potential response.
9 pages., Online via UI electronic subscription., Researchers used unique data collected from consumers, vendors, and markets in a rural region of New York State to develop an empirical model of subjective and objective measures of vendor performance to identify important factors for improved market sustainability. Results suggested four inter-related planning recommendations when considering market and public policyinterventions.
9 pages., Via online journal., As a consequence of recent food safety incidents, consumer trust in European food safety management has diminished. A risk governance framework that formally institutes stakeholder (including consumer) consultation and dialogue through a transparent and accountable process has been proposed, with due emphasis on risk communication. This paper delivers actionable policy recommendations based on consumer preferences for different approaches to food risk management. These results suggest that risk communication should be informed by knowledge of consumer risk perceptions and information needs, including individual differences in consumer preferences and requirements, and differences in these relating to socio-historical context associated with regulation. In addition, information about what is being done to identify, prevent and manage food risks needs to be communicated to consumers, together with consistent messages regarding preventative programs, enforcement systems, and scientific uncertainty and variability associated with risk assessments. Cross-cultural differences in consumer perception and information preferences suggest a national or regional strategy for food risk communication may be more effective than one applied at a pan-European level.
10 pages., Online via UI electronic subscription., Results of 251 consumer surveys in four UK supermarkets revealed that only 5.6% nominated country of origin as one of the reasons for choosing a fresh food item they had just purchased. However, stated preference surveys in the street found that 21.5% indicated that "food miles" or "the long distance it travels" would stop them buying New Zealand products. "What people say may differ substantially from what they actually do in regard to 'food miles'."
9 pages., Online via UI electronic subscription., The study involved a survey among 39 respondents from the milling industry and supermarkets, the main processors and distributors of maize products, in seven urban centres of Kenya. Identified information sources, knowledge level of biotechnology, and perceptions and preferences involving genetically modified food.
