Although the organic sector is still relatively small, the demand for organic food is increasing throughout the world. The characterization of consumers' perception of and attitudes towards organic food is important to enable the development of marketing policies aimed at attracting conventional consumers to the sector. Consumers' behaviour studies must be conducted specifically for different regions and countries as perceptions and attitudes vary across the world. In the present study, a questionnaire was designed for administration to consumers in Galicia (Northern Spain). The questionnaire was administered to 830 consumers in 200 establishments to obtain data about the consumers' perception of and attitudes towards organic food. The survey results showed that one‐third of responders consume organic food and that the typical profile of a consumer of organic food is a middle‐aged, medium‐high class, university‐educated female living in a large village, who shops in supermarkets and preferably consume vegetables, fruits and eggs. Most people who declared that they consume organic products confuse these with home and locally produced food, indicating the potential for growth of the organic sector by providing such consumers with appropriate information. Most consumers (including conventional consumers) have a good opinion of organic food and consider that it is better for health, is of better quality than conventional food and avoid pesticide residues. However, price continues to be a barrier to the consumption of organic produce. Most respondents stated that they would consume more organic food if the price was only between 10% and 30% higher than the conventional equivalent. Finally, organic consumers in Galicia showed positive attitudes towards using local breeds in organic agriculture, both for producing food and for ecotourism and educational activities. Such activities could contribute to conserving breed biodiversity and adding value to organic farming.  相似文献

This paper analyzes the gender wage gap across the wage distribution using 2010 data from the German Statistical Agency. I investigate East and West Germany and the public sector separately to account for potential heterogeneities in wage gaps. I apply unconditional and conditional quantile regression methods to investigate the differences between highly paid men and women in distributions conditional and unconditional on covariates. The results indicate increasing gender wage gaps in all estimations, suggesting that there is indeed a glass ceiling over Germany even after controlling for a large set of observable characteristics (including occupation and industry). This finding is even more pronounced when also taking bonus payments into account.  相似文献

Food product innovations are characterized by high flop rates. In an early development stage, manifold product formulations seem feasible. To determine the most promising product option, market research can help, but is frequently considered too costly and complex. We assess the applicability of the van Westendorp approach, an inexpensive and simple method, for guiding early product design and pricing decisions for novel foods. Findings from a between-subject experiment for meat substitutes consisting of different shares of micro-algae indicate that micro-algae, while a cost driver, has little effect on price preferences. Implications for novel food product design, market research, and retailing are discussed.  相似文献

From 2011 in Australia, if over 25% of shareholders vote against a non‐binding remuneration resolution, firms are awarded a ‘strike’. We examine 237 firms that receive a strike relative to matched firms, and find no association with any measure of CEO pay. However, we do find that strike firms have higher book‐to‐market and leverage ratios, suggesting that the remuneration vote is not used to target excessive pay. We also find that firms respond to a strike by decreasing the discretionary bonus component of CEO pay by 57.10% more than non‐strike firms and increasing their remuneration disclosure by 10.95%.  相似文献

我国部分上市公司的董事长和总经理领取的年薪完全相同。这种高管同酬的确定依据是什么?高管同酬是否具有激励效率?高管同酬又会对公司绩效产生什么影响?文章利用2007-2012年 A 股上市公司数据,对高管同酬及其经济后果进行了实证分析。研究发现,部分上市公司出现高管同酬,主要是因为高管薪酬由公司政治因素或内部薪酬比较所决定,而并非遵循最优契约观所寓示的“效率逻辑”;与高管异酬的公司相比,高管同酬公司的董事长薪酬激励缺乏效率;高管同酬对公司未来财务绩效产生了显著的负面影响。这表明在中国情境下,高管薪酬契约的设计和实施需要关注公司权力博弈或内部薪酬比较等非经济性因素的影响。  相似文献

In spite of high importance of information technology (IT) investments, managers do not have sufficient guidelines to formulate IT investment strategy of a firm. In this paper, we review the literature to determine the factors that influence the IT investment strategy. The concept of IT investment strategy so far considered two domains: intensity and proactiveness; we enhance this concept by adding the domain of investment focus. Through this review, we made an attempt to answer three strategic questions related to IT investments: (i) level of investment that a firm should make in IT, that is, investment intensity; (ii) areas of firm where these investments should be more focused, that is, investment focus; and (iii) timing of investment, that is, whether to be an early mover in adopting IT or whether to invest relatively late compared to competitors.  相似文献

The authors extend prior literature by examining, in two distinct field settings, smallest meaningful pay increases (SMPIs) in terms of magnitude, behavioral intention, and affective reactions. In Study 1, a two‐wave study of 177 employees of a university medical center in the United States, the authors find stable thresholds of about 5.0 percent for positive reactions to pay increases (magnitude [5.4 percent], behavioral intentions [4.2 percent], and affective reactions [5.6 percent]). In Study 2, a sample of 495 university employees in Finland, the authors also find stable but slightly higher thresholds of about 8 percent for behavioral intentions (8.4 percent) and positive affective reactions (7.2 percent) to pay increases. They also find threshold effects of ?5.7 percent for behavioral intentions and ?5.8 percent for negative affective reactions in response to restricted future pay increases levied in the transition to a new pay system. Discussion of the results centers on pay raise administration and future research regarding implied and direct pay reductions. © 2015 Wiley Periodicals, Inc.  相似文献

从社会资本角度定量研究农民灌溉水价支付意愿影响因素,采用信任指数和互助指数对社会资本进行量化,结合开放式和二分式问卷格式,改进了获得农民灌溉水价支付意愿相关数据的引导技术,并采用多元线性回归方法建立了农民灌溉水价支付意愿影响因素定量分析模型。以皂河灌区为研究区域,通过问卷调查收集基础数据,采用提出的模型分析了各因素对农民灌溉水价支付意愿的影响情况。结果表明:社会资本是影响农民灌溉水价支付意愿的重要因素之一;农户主要劳动力人数、耕地面积、供水及时性、管水者工作能力等因素对农民灌溉水价支付意愿也具有显著影响。灌溉水价的改革,应重视农民社会资本并提高灌区供水服务水平等。  相似文献

Evaluation of value of irrigation water is essential for supporting policy decision making relating to investments in the irrigation sector, efficient allocation of irrigation water and water pricing and for crafting policies to compare the variable impacts of water reform within and across sectors of the economy. This paper asks the question of how much an established irrigator would pay for water and at what price farmers planning to expand the area they have under irrigation would consider paying for the right to access water. An analytical framework is developed to estimate the net present value of both annual and perennial agricultural activities in the Murrumbidgee catchment. Using these estimates the total value of water used in Murrumbidgee catchment is estimated. An aggregate water supply curve is derived for the catchment from where water may be acquired from irrigators for environmental flows.  相似文献
