Forecasting another’s enjoyment versus giving the right answer: Trust, shared values, task effects, and confidence in improving the acceptance of advice

In two experiments, participants received advice from another participant on a task either with a correct answer (intellective tasks) or without a correct answer (judgmental task), in which the participant had to make a forecast. In both experiments, the level of trust in the advisor and a perception of the advisor having similar values were important predictors of the acceptance of advice for a judgmental, taste forecast task, whereas advisor confidence was a more important predictor of the acceptance of advice on the intellective task. In Experiment 2, the face-to-face interactions between the decision-maker and the advisor were videotaped and coded. Advisors provided more information to decision-makers for the taste forecast than for the intellective task. Further, whether the advisor provided information to supplement their recommendation or not was a significant predictor of the acceptance of advice on the taste forecast, but not on the intellective task. The results are discussed in the context of previous research on advice, which has predominately used intellective tasks.     

The relative income hypothesis

Despite its theoretical dominance, the empirical case in favor of the permanent income hypothesis is weak. Contrary to one of its basic implications, a growing body of evidence suggests that rich households save a higher proportion of their permanent income than poor households. We propose an overlapping-generations economy where households care about relative consumption. As a result, an individual's consumption is driven by the comparison of his lifetime income and the lifetime income of his reference group; a permanent income version of Duesenberry's (1949) relative income hypothesis. Across households the savings rate increases with income while aggregate savings are independent of the income distribution.

基于消费文化视角的低碳消费行为形成理论模型研究

低碳消费是实现现有经济模式向低碳经济模式转变的必然环节和促进手段。个体消费惯性可能阻止个体消费者低碳消费行为的发生。通过对社会消费文化对个体消费行为包裹作用的研究发现,要想使个体消费者最终选择低碳消费行为,要么提高社会消费文化的强度,加大对个体消费行为的包裹作用;要么改变舆论导向,改变消费者的消费价值观。     

公路货运站场向现代物流中心转化的对策研究
