The UK government has set an ambitious target of reducing greenhouse gas emissions by 80% before 2050. An interesting segment that could help to achieve this is older consumers, due to their growing numbers. There seems to be a lack of attention, in the research looking specifically at different age categories of older consumers’ green behaviour, and whether their level of greenness can be explained by their personality. Using Socioemotional Selectivity Theory and Time Perspective, the research presented here was designed to provide an exploratory analysis of how the green behaviour of older consumers is explained by their personality types. Based on the responses of 204 older consumers in the UK, our results find the openness personality trait to be positively linked to green behaviour, whilst the extraversion personality trait is negatively related to green behaviour. Although the level of green behaviour increased with older consumers’ age, this did not reach significance. 相似文献

The current study draws on the collective futures framework to examine how visions of future societies where most people consume plant-based, vegetarian or vegan diets are related to current support for social change towards plant-based diets. Participants were 506 university students in Aotearoa New Zealand invited to imagine a society in 2050 where most individuals consume a plant-based, vegetarian, or vegan diet. A thematic analysis was conducted on responses to an open-ended item asking how these future societies would be different to today. Participants reported a variety of potential positive and negative outcomes for individuals and wider society. Subsequent analyses of attitudes scales investigated the relationships between the collective dimensions of plant-based future societies and support for policies to promote plant-based diets. For a vegetarian future, the strongest predictor of current support for social change was the expectation that widespread vegetarianism would reduce societal dysfunction. For a vegan future, the strongest predictor of support for social change was an expectation of increased warmth in a vegan society. Implications for theory and advocacy are discussed. 相似文献

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in , the date of decision and in , the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on . The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents. 相似文献

This paper aims to investigate organic food consumption based on the perspectives of an extended research model by integrating the theory of consumption value (TCV) and the theory of reasoned action (TRA). First, we tried to find out how five consumption values of functional, social, emotional, conditional, and epistemic in classic TCV influence consumption choice especially in the sustainable consumption domain of organic food, interpreted as green perceived value (GPV) in the reflective-reflective second-order latent. Second, as an attempt to extend the classic TRA, this study included trust and perceived knowledge in the research model in addition to the subjective norm, attitude, and behavioral intention. A partial least square structural equation method (PLS-SEM) was adopted to examine our research model with 251 samples. Our results revealed that GPV significantly affects consumer attitudes. Consumer attitudes and subjective norms also have a significantly positive effect on purchase intention. As an extended TRA, GPV has a significantly positive effect on trust while trust significantly impacts purchase intention. Further, perceived knowledge positively influences attitude and trust. By jointly considering TCV and TRA, this study proposes several implications emphasizing how GPV and perceived knowledge affects consumers’ organic food consumption choice based on the role of increased trust. 相似文献

最优能源强度与我国经济增长 总被引:7,自引:0,他引:7
本文通过一个内生增长模型对能源消费与经济增长的关系进行了分析,证实存在使经济增长率最大化的最优能源强度,并且最优能源强度与能源价格反方向变动.在此基础上,估计了近年来我国的最优能源强度,并测算了实际能源强度与最优值的差距.结果表明,近年来我国实际能源强度高于最优值达3万吨标准煤/亿元以上,且有不断上升的趋势.最后提出了在保持最优能源强度的前提下降低能源消耗的政策建议. 相似文献
