Several consumer studies have shown considerable market potential for sustainable meat products, however, their markets shares are still marginal. In Germany, the sustainable aspects “organic,” “local origin,” and “animal welfare” are of special interest. To obtain a precise overview of potential target groups for these meat categories and their choice of store format, 620 German consumers were surveyed on their attitudes toward sustainable meat production and their shopping behavior. First, target groups based on consumers’ attitudes were identified by cluster analysis, taking into account possible overlaps. Consumers were also clustered by their store format choice and their preferred type of meat packaging. A cross tabulation of the results then provided insights into which store format and type of meat packaging is preferred by the target groups for sustainable meat products. Due to overlaps found in the target groups, the existence of important subgroups was shown. Amongst the target groups, only a slight preference for unpackaged meat products was found. Basically, the offer of sustainable meat products appears of interest for all store formats, with particular emphasis on supermarkets. The results of this study can support producers and retailers developing new and tailored marketing strategies for sustainable meat products. 相似文献

The purpose of this study is to examine the effects of consumption values (i.e., functional value, social value, emotional value, conditional value, epistemic value, environmental value, and health value) on women’s choice behavior toward organic yogurt. Structural equation modeling is used to assess data collected by a questionnaire survey. The results indicate that functional value–quality, functional value–taste, and functional value–price; conditional value; epistemic value; and health value have positive effects on choosing organic yogurt by women, and social value, emotional value, and environmental value have no effects on the subject. Among variables, epistemic value and health value have the highest impact on consumer choice behavior toward organic yogurt. So this study concludes that the main influence factors on choice behavior regarding organic yogurt are epistemic value and health value. In fact, consumers have high knowledge about organic yogurt benefits related to their health. 相似文献

The introduction of farmer participatory approaches over the past decades has to some extent improved the relevance and uptake of research results. While R&D prioritization increasingly involves more stakeholders, including the private sector, policymakers and civil society, building ecological literacy among all stakeholders is urgent, especially for sustainable agricultural development. A case study of an emerging fruit innovation system in Guinea, West Africa, highlights the challenges of supply- and demand-driven approaches to R&D prioritization. Shallow ecological knowledge and a blind faith in ‘modern’ technologies by scientists and farmers alike distort prioritization. Locally available, appropriate technologies are dismissed in favour of high technologies that are inaccessible to most smallholder growers. Strengthening the ecological literacy of all stakeholders may help to overcome this bias. On the other hand, building socio-technological literacy would allow innovation intermediaries, who typically act as brokers between the demand- and supply-side of technologies, to better understand the social and institutional contexts of technologies and how these affect potential uptake by poor farmers. Member centres of the Consultative Group on International Agricultural Research (CGIAR) could use the notion of ecological and socio-technological literacy to better understand supply and demand of technology and to work more effectively with their partners towards pro-poor and sustainable agricultural development. 相似文献

基于样区20年气象资料统计结果和2006年土壤有机碳实测值,分析了东北样区内土壤活性有机碳各组分的空间分布格局及其与年均温(t)、降雨量(p)、有效积温和p/t(降雨量/年均温)之间的关系。结果表明:样区内土壤活性有机碳各组分沿纬度呈现出南低北高的分布趋势;活性有机碳各组分与土壤有机之间具有显著的正相关性;活性有机碳组分之间具有较强的相关性;活性有机碳各组分与气候因素之间存在良好的相关性。活性有机碳各组分与年均温之间的相关性大于活性有机碳各组分与降雨量之间的相关性。 相似文献

Recent public policy debates have led to increased calls for full transparency of executive compensation. However, in practice, many firms are reluctant to disclose the full details of how they link executive compensation to performance. One possible reason for lack of full disclosure is that managers use their power to hide the details of their compensation plan in order to disguise opportunistic rent extraction. If this is the reason for secrecy, then public policy designed to force firms to provide full disclosure is unlikely to be resisted by shareholders. However, another possible explanation for less than full transparency is that some degree of secrecy about executive compensation may be in the interest of the company and its shareholders. If this explanation is correct, then public policy moves to increase transparency may be met by counter moves designed to protect managers and shareholders from such policies. In this paper we investigate if full disclosure of executive compensation arrangements is always optimal for shareholders. We develop a model where optimal executive remuneration solves a moral hazard problem. However, the degree to which the moral hazard problem affects the shareholders depends on hidden information, so that disclosure of the executive compensation scheme will typically reveal the hidden information, which can be harmful to shareholders. The model derives, therefore, the optimal disclosure policy and the optimal remuneration scheme. We find that the shareholders are better off pre‐committing not to disclose the executive compensation scheme whenever possible. Executive directors are shown to be better off too in the absence of disclosure of executive compensation schemes. An argument for mandating disclosure is that it provides better information to shareholders but our analysis demonstrates that disclosure does not necessarily achieve this objective. The results suggest that less than full disclosure can be in the interest of shareholders, the reason for this being that disclosures cannot be made selectively to shareholders but will also be made to strategic opponents. This will be the case if the board of directors and the remuneration committee includes enough independent directors. Whether or not non‐disclosure to shareholders is in their interest is however an empirical matter involving a trade‐off between the proprietary costs associated with disclosure to shareholders and the costs of potential collusion between executive and non‐executive directors associated with non‐disclosure. 相似文献
