This paper investigates whether reframing an issue related to sustainable consumption can influence citizens' attitude towards that issue. Our investigation focuses on the case of Fair Trade in Flanders, Belgium. Fair Trade contributes to sustainable development by offering better conditions to marginalized producers in the South. Using an internet-based experimental setup, 1617 individuals were exposed to an NGO-based frame, a retailer-based frame, an experimental frame or no frame. Statistical analysis then indicated whether the experimental frame performed better than the control group and the other frames in shifting people's attitudes. Our results suggest that a brief exposure to a combination of tone, messenger, value and metaphor that signals the systemic aspects of Fair Trade may be successful in shifting the attitude and opinion of Flemish consumers/citizens in favour of Fair Trade. Our analysis suggests that the foundations metaphor that has been developed in the context of the environmental impact of food production can also be applied in the context of the social impact of food production. 相似文献

Crop genetic diversity, farm productivity and the management of environmental risk in rainfed agriculture 总被引:1,自引:0,他引:1
This paper presents an assessment of the linkages between cropgenetic diversity, farm productivity and risk management. Aflexible moment-based approach is used to analyse the impactof crop genetic diversity on the mean, variance and skewnessof yield. Using farm-level data from Sicily (Italy), econometricevidence shows how crop genetic diversity can increase farmproductivity and reduce risk exposure. The empirical resultsindicate that crop genetic diversity can reduce variance, butonly if pesticide use is low. Furthermore, high diversity levelscan reduce downside risk exposure (e.g. the risk of crop failure).This provides useful insights on the linkages between resilienceand crop genetic diversity. 相似文献

Summary Self‐service mini‐storage facilities normally occupy two or three acres and contain about 500 or 600 small independent units totalling about 50 000 ft2. They are a profitable and widespread investment in the US and fulfill small‐scale community needs. Users, who rent on a monthly basis, are households and businesses with small scale storage needs. Main road locations, in above average income areas, and tight security are keys to success. Management is effected by a live‐in on‐site manager and by a simple tenancy agreement. The main planning problems are access, visual intrusion and the control of undesirable uses. The author speculates on the success of this property concept on its transfer to Britain. 相似文献

[目的]通过测算各省区粮食增产潜力和各省区可比耕地资源量,揭示不同阶段我国及各省区粮食生产及增产的特点及原因,揭示我国今后粮食增产的方向。[方法]结合生产力相对指数与耕地面积分析我国各省耕地资源量,测算了复种指数和单产对我国及各省区粮食增产的贡献率,测算了我国各省区粮食增产的潜力。[结果]我国各省区人均粮食产量差异明显扩大。1985~1998年间,粮食单产对粮食产量增加的贡献率为85.35%;1998~2003年间,我国粮食总产量下降,播种面积减少是主要原因;2003~2013年间,单产增加依然是增产主因,但播种面积增加的贡献明显提高。1985年相对生产力耕地资源的省际差异明显大于2013年,据该文估算,我国可增产粮食22.9%~43%,复种指数对于粮食增产的潜力十分可观。[结论]近30年来,我国粮食生产格局是\"南降北升\",播种面积差异是粮食生产省际差异的主因。1985~2013年间,粮食播种面积仅占农作物增播面积的15.48%。大多省区耕地复种指数提升空间较大,但多数省区现实的复种指数却在下降,原因是农业生产比较利益低下。进一步提高单产的边际约束效应明显凸显,提高复种指数应该是我国提高粮食产量的方向。 相似文献

We examine whether countries with low initial levels of agricultural total factor productivity (TFP) tend to ‘catch up’ with the technology leaders. We first compare relative levels of agricultural TFP, capital services and labour input levels in agriculture for 17 OECD countries between 1973 and 2011. Then we apply (conditional) convergence analysis to the panel data to examine the speed of convergence and test whether the convergence is transitory or permanent by analysing TFP changes over the business cycle. Capital intensities, quality improvement of capital, factors such as human capital spillovers, and certain agricultural policies are conditioning variables. We examine how differences in relative capital intensities affect agricultural productivity convergence over the business cycle. We find evidence that the speed of convergence increases during periods of contraction in economic activity. 相似文献

Incentives in agriculture are highly distorted. It has long been argued that these distortions were a key explanation for differences in supply and productivity across countries, but the empirical evidence is limited. We revisit this issue using data on policy distortions across 63 countries for the period 1961–2011. We estimate the effects of differential changes in agricultural distortions across countries on supply and productivity. We highlight concerns in our analysis and previous work about endogeneity that biases the estimated effect downward—countries that lose comparative advantage are likely to increase support for agriculture. We address these concerns by including country and region-time fixed effects, along with a rich set of controls. Overall, we find evidence that enhanced incentives through policy changes can increase the rate of production growth, with about half of the increase due to productivity increases. This result is strongest in Sub-Saharan Africa where anti-agricultural policies on exports were reduced and in Europe where pro-agricultural policies on imports were reduced, driven largely by external pressure. Endogeneity appears to be strongest in Asia where countries have followed the typical pattern of raising support for agriculture during industrialization due to a rising farm-urban income gap. 相似文献

Land Distribution and International Agricultural Productivity 总被引:2,自引:0,他引:2
The unequal distribution of agricultural land is often cited as a source of inefficiency in agriculture. Previous cross-country studies of agricultural productivity differences, though, have not considered land inequality. This article addresses this issue by using cross-country data on inequality in operational holdings of agricultural land from Deininger and Squire (1998) . In an estimation of an agricultural production function, the Gini coefficient for land holdings is found to have a significant negative relationship with productivity. This is consistent with the existence of heterogeneity in productivity by farm size within countries. A one standard deviation drop in the Gini coefficient implies an increase in productivity of 8.5%. 相似文献

Production Contracts and Productivity in the U.S. Hog Sector 总被引:3,自引:0,他引:3
This article measures the impact of contracting on partial and total factor productivity and the production technology of U.S. hog operations. A sample selection model accounts for the fact that unobservable variables may be correlated with both the operators' decision to contract and farm productivity. Results indicate that the use of production contracts is associated with a substantial increase in factor productivity, and represents a technological improvement over independent production. Results also identify determinants of farmers' decisions to contract and other factors influencing farm productivity. 相似文献

Small businesses and commercial property leasing are two important policy areas for the UK Government. Hence, it has been promoting flexibility and choice in commercial leases as part of a wider enterprise and productivity agenda, and attempting to improve the awareness of small business tenants on property leasing issues. This article addresses issues of flexible leasing specific to small business tenants. Through an analysis of lease data from Investment Property Databank and a questionnaire survey of tenants in England and Wales, it examines the negotiation process, outcomes, and trends stemming from that process. There are major differences between small business leases and those for medium and larger sized companies. Small businesses have shorter leases, fewer rent reviews and earlier breaks. There are also differences in the negotiation process, most noticeably as between the very small micro business and other small businesses. A significant number of very small tenants take no commercial advice when negotiating leases even though many of them have no prior experience of taking leases; the smaller the business the less likely they are to take advice. While flexibility and choice in leasing has improved in recent years, the awareness of small business tenants on leasing issues is less good. Part of the problem may lie in the difficulties of dissemination to a diverse group. However, if voluntary mechanisms cannot demonstrably improve information flows to micro businesses, the small business issue may yet be the catalyst for legislation on all business leases, legislation the UK property industry has fought desperately to avoid for the last 13 years. 相似文献

This paper explores how business occupiers decide whether and where to relocate. It captures the experience and behaviour of a range of sizes and types of business occupier and subjects their decision‐making processes to detailed scrutiny. A linear three‐stage decision model is used to sequence and structure interviews with individuals who have intimate involvement with the relocation of 28 firms and organizations in Tyne and Wear, in the north‐east of England. The ‘constant comparative’ method is used to analyse the interview data, from which emerges 18 key concepts, comprising 51 characteristic components. Using an axial approach, these are organized into 10 cross‐cutting themes that represent the main areas of consideration or influence on the thinking of the people involved in determining whether a firm or organization should relocate and, if so, where to. The resulting analysis finds that organizations adopt varying degrees of sophistication when making relocation decisions; small firms are more inclined to make decisions based on constrained information; larger organizations adopt a more complex approach. Regardless of firm size, key individuals exert considerable influence over the decision‐making process and its outcome. 相似文献
