This paper explores an unusual community-supported agriculture pilot project in London, concentrating on the contribution of ICTs in its development and impact. The paper contextualises the project within wider waves of local food activism and reflects on the relevance of using ICTs to increase awareness and community participation in the production and consumption of locally-grown food. The results are also analysed in light of the author's parallel research on the use of ICT for agricultural development, or “e-agriculture”, in Kenya. The paper contributes to ongoing debates on ICTs and agricultural development, by highlighting community-building and the emergence of new voices and conversations as key roles played by ICTs, contributing to the development of more participatory, resilient and locally-centred food systems. The results of the pilot however also acknowledge the essential role played by activities in real life in building communal food growing practices, which can be enhanced but not substituted by online communities. 相似文献

Asset prices and the equity premium might reflect doubts and pessimism. Introducing these features in an otherwise standard New-Keynesian model changes optimal policy in a substantial way. There are three main results: (i) asset-price movements improve the inflation-output trade-off so that average output can rise without much inflation costs; (ii) a “paternalistic” policymaker – maximizing the expected utility of the consumers under the true probability distribution – chooses a more accommodating policy towards productivity shocks and inflates the equity premium; (iii) a “benevolent” policymaker – maximizing the objective through which decisionmakers act in their ambiguous world – follows a policy of price stability. 相似文献

This study examines the effect of the state of the economy and inventory on interest-adjusted bases and expected returns for five energy commodities. We find that interest-adjusted bases and returns have a business cycle pattern. Consistent with the theory of storage, demand shocks near business cycle peaks generate negative interest-adjusted bases and positive returns. In recessions, the bases become positive, and the average returns are negative. Our regression results also show that the interest-adjusted bases of energy commodities are counter-cyclical and the expected returns are pro-cyclical. For petroleum commodities, inventory has a significant effect on interest-adjusted bases at low levels of inventory, whereas at high inventory levels the effect of inventory on the bases is weak. Finally, we find that the bases and economic conditions predict spot returns in energy commodity markets. 相似文献

Country-of-origin labeling (COOL) is being implemented in different forms and degrees in the United States and other countries across the world. The first implementation of mandatory country of origin labeling (MCOOL) in the United States was for seafood in 2005. This is an example of partial MCOOL because it exempts the foodservice sector and excludes processed seafood from labeling. Using a conceptual framework, we analyze the welfare impacts of partial MCOOL when compared to no, voluntary, and total mandatory COOL, taking into account imperfect competition in the downstream markets, information asymmetry, and diversion of low-quality product to the unlabeled market. The model is general enough to apply to any incomplete regulation for which the perceived low-quality product is required to be labeled, such as the labeling of genetically modified food in the European Union. Our results show that when consumers have a strong enough preference for domestic relative to imported product, regulators can overestimate the gain in consumer welfare from partial mandatory labeling if they ignore the diversion of lower quality imports to the unlabeled sector. We show that if the preference for domestic product is large enough, total MCOOL benefits the home market the most overall, including domestic consumers and producers, but not the imperfectly competitive downstream agents. However, if total MCOOL is too costly to implement, partial MCOOL is the second-best solution, but only if consumers falsely believe the unlabeled product to be of higher quality than it truly is. Our results suggest more research is needed to determine the extent to which consumers value the information provided by MCOOL and to enable regulators to consider the welfare impact of diversion in evaluating incomplete mandatory labeling regulations. 相似文献

Bangladesh has made considerable progress against human development indicators in recent years, but malnutrition resulting from poor dietary diversity and low micronutrient intakes remains entrenched. Fish is central to the Bangladeshi diet and small fish species are an important micronutrient source. Although fish consumption per capita has increased in recent years as a result of rapid expansion of aquaculture, it is likely that consumption of fish from capture fisheries (including small indigenous species particularly rich in micronutrients), has declined. This paper evaluates data on fish consumption collected in Bangladesh by the International Food Policy Research Institute in 1996/7 and 2006/7 to assess changing patterns of fish consumption and their implications for food and nutrition security. This analysis indicates that growth of aquaculture has been positive, mitigating a sharp reduction in the quantity of fish consumed from capture fisheries and smoothing out seasonal variability in consumption. However, increased availability of fish from aquaculture may not have fully compensated for the loss of fish from capture fisheries in terms of dietary diversity, micronutrient intakes and food and nutrition security, particularly for the poorest consumers. A range of approaches are recommended to sustain and enhance the contributions capture fisheries and aquaculture make to food and nutrition security in Bangladesh 相似文献

The paper analyses farm worker welfare on three different types of farms in Kenya producing vegetables for export. The three types of farms differ by certification to international production standards as well as by size. A multidimensional approach measures welfare using human capital, income, physical and mental health, and life satisfaction. The findings suggest that GlobalGAP certification has a positive impact on worker welfare as farm workers are given more training. Workers on large certified farms earn more than those on small farms but also show more health problems. Certification on small farms is associated with higher satisfaction of workers with their life compared to workers on non-certified small farms. From a development policy perspective this paper does not support a clear cut policy on which types of farm to support as overall benefits of a support strategy will depend of the number of beneficiaries reached through the different farm types. 相似文献

The entire food value chain and diet of low and middle income countries (LMICs) are rapidly shifting. Many of the issues addressed by the nutrition community ignore some of the major underlying shifts in purchases of consumer packaged foods and beverages. At the same time, the drivers of the food system at the farm level might be changing. There is a need for the agriculture and nutrition communities to understand these changes and focus on some of their implications for health. This rapid growth of the retail sector will change the diets of the food insecure as much as that of the food secure across rural and urban LMIC’s. This short commentary contents that current research, programs and policies are ignoring these rapid dynamic shifts. 相似文献

Sources of risk in contemporary tourism vary over a long array of phenomena ranging from the risk of terror attacks to risks related to food and consumption. Currently, alleged food-risk sources such as Creutzfeldt–Jacobs Disease (CJD; commonly known as “Mad Cow Disease”), Salmonella, Scrapie disease and even genetically modified food are salient in mass media.In the present study, we addressed the pervasiveness of tourists’ judgements of such food-related risks. As part of a larger study, some 1880 individual tourists (from 48 different nations) answered a questionnaire pertaining to food-risk issues. Based on the logics of the availability heuristic, we expected that food risks would be judged to be lower in one's own home country than abroad. We also expected that people would rate various sources for food risk differently when rating food risks at home and abroad.The results indicate that risks linked to food are indeed perceived to be higher abroad than at home, regardless of where the respondents’ homes are, although attributions of risk to the various risk sources seem to vary between at home and abroad. The results also show a significant, but moderate correlation between travel experience and food-risk judgements abroad and at home. The results also indicate cultural differences in risk judgements concerning food. 相似文献

Dynamic pricing techniques allow using a number of variables in a tactical way compared to standard catalogue prices. This study merges in a conceptual model the relevance of the tactical and the strategic dimension of these variables, classified according to their tangible, reputational or contextual nature.To empirically validate the hypotheses, a database of 21.596 price observations was retrieved from booking.com. The study presents a hedonic price function, using the Shapley-Owen decomposition of the R-squared to elicit the importance of each group of factors. Further, a hierarchical cluster analysis measures the presence of heterogeneity across operators.The results show that online reputation is gaining importance over the traditional star rating. Despite the tangible variables remain of paramount importance, the findings suggest the relevant role of contextual variables in short-run price variations. The players operating in the tourism and hospitality industries should integrate these findings when designing pricing strategies. 相似文献
