西安市人口年龄结构变动趋势对老年消费市场需求的影响分析

人作为消费活动的主体,其内部结构的变化必然会导致消费的变化。本文通过对西安市人口年龄结构的变动、老年人口收入来源及消费行为的分析,发现西安市人口结构的变化对老年消费市场需求既有积极的促进作用,也有消极的负面影响。提出政府与企业应厘清人口变动与消费之间的关系,扬长避短,尽可能发挥其积极影响作用,以促进扩大老年消费市场的需求。     

The compelling urge to misbehave: Do impulse purchases instigate unethical consumer behavior?

The present research explores the relationship between impulse buying and unethical consumer behavior. This work is based on the surprising results of an unrelated study, during which we observed that participants shopping for impulse products were more likely to cheat to obtain a more expensive product than participants shopping for regular products. Based on these findings and building on previous research on the relationship between impulsiveness and delinquency, three studies were set up to test the impact of impulse buying on different forms of unethical consumer behavior. The results confirmed that consumers making an impulse purchase were more likely to behave unethically than consumers making a regular purchase. These findings illustrate there is a dark side to impulse buying for retailers.     

Search With Learning for Differentiated Products: Evidence from E-Commerce

This article provides a method to estimate search costs in a differentiated product environment in which consumers are uncertain about the utility distribution. Consumers learn about the utility distribution by Bayesian updating their Dirichlet process prior beliefs. The model provides expressions for bounds on the search costs that can rationalize observed search and purchasing behavior. Using individual-specific data on web browsing and purchasing behavior for MP3 players sold online we show how to use these bounds to estimate search costs as well as the parameters of the utility distribution. Our estimates indicate that search costs are sizable. We show that ignoring consumer learning while searching can lead to severely biased search cost and elasticity estimates.     

从经济普查看区域工业结构趋同的原因

 本文发现反映地方保护的GDP增长率强化了省际间产业结构的趋同,进一步验证了使用其他指标度量地方保护的已有同类研究的结论,因此有必要改变现行的用GDP增长率作为地方官员晋升依据的做法,重视国民福利的提高,并将民意对官员的评价逐步纳入地方官员晋升的考核范围。     

战略性新兴产业统计标准研究

 自从2010年10月国务院颁布《国务院关于加快培育和发展战略性新兴产业的决定》以来,已有专家学者对战略性新兴产业的内涵进行了分析和诠释,但是鲜有关于战略性新兴产业统计标准方面的研究。本文在现行的国民经济行业分类框架下,对战略性新兴产业进行了划分和界定,在此基础上利用2004年和2008年两次经济普查的数据对其增加值进行计算。计算结果显示,2008年我国战略性新兴产业占GDP的比重大约为5.82％,其中,制造业中战略性新兴产业占GDP比重为3.33%,服务业中战略性新兴产业占GDP比重为2.49%。文章最后对我国战略性新兴产业的发展现状进行了分析,并提出了政策建议。     

我国战略性新兴产业发展的总体特征、制度障碍与机制创新

战略性新兴产业来源于基础研究和原始创新,其发展过程严格遵循着科技创新成果产业化的基本规律,不确定性是战略性新兴产业形成期最突出、最典型的本质特征。与技术追赶的工业化过程不同,战略性新兴产业的培育和发展,需要政府在企业制度、科技制度、融资制度、市场管理制度、干部考核激励机制等方面克服制度障碍并进行体制机制创新。     

我国存在霸王条款的深层原因检讨与反思

通过对我国霸王条款存在现状的叙述与存在问题的归纳以及域外立法对霸王条款法律规制的考察,可以发现:霸王条款之所以在我国盛行,除了有在一般市场经济国家产生的共性原因外,其深层原因是我国存在行政性垄断、消费者维权渠道不畅、公民法律意识淡薄等。因此,规制霸王条款的根本出路在于打破垄断,完善反垄断的相关立法,同时还必须通过加快修改和完善消费者保护立法,以提升消费者维权意识和能力。     

Shopping Model of the Time-Sensitive Consumer

The shopping behavior of time-sensitive consumers has been modeled as an economic model of choice. Consumers are said to balance the costs of time spent commuting to the store and in the store with storage costs and other nontime costs of shopping. In so doing, these consumers tend to minimize their overall costs. Propositions are developed and tested using this economic model of shopping. The model is extended beyond time sensitivity to include deal proneness; further propositions are developed and tested using the extended model. The empirical results support the derived models.     

The Internal Validity of the Trade-Off Method of Conjoint Analysis

The discovery of consumers' preferences for multiattribute products/services has recently become possible with the development of conjoint measurement techniques. Conjoint analysis uses an individual's preference ranking or rating of some deliberately manipulated constructs of a concept to determine his/her numerically valued preferences for levels of those attributes that comprise the concept. Generally speaking, there are two methods of data collection for conjoint analysis: the full profile and the trade-off methods. This paper calls into question the internal validity of the preferences obtained via the trade-off method. An empirical analysis, which is based on the subjects' preferences for selecting a hospital, clearly shows that the estimates derived from the trade-off method may not reflect consumers' true preferences.
