Research needs for assessing online value creation in complex consumer purchase process behavior

Consumers face considerable frustration when purchasing structurally and/or semantically complex high-involvement products online. Reliance on computer-mediated communications for their information needs may result in functional and emotional frustration from information overload and lack of personal trust. This paper proposes a responsive real-time information system as a proxy for a perceptive sales representative who assesses customer needs based on information exchanges and then offers appropriate responses. By tracking and analyzing a consumer's online activity, vendors can offer information relevant to the consumer's real-time needs, facilitating their purchase process. In essence, this is a real-time value co-creation process based on the consumer offering cues to vendors through their key strokes and mouse click activity. This allows for differentiated information offerings for inexperienced and more experienced consumers, creating value by dynamic information serving. Where appropriate value is created, consumers will experience less frustration and continue online, rather than possibly moving offline or to alternative vendors. In examining the bases of consumer information needs in complex purchases, this paper identifies the data required to enable a responsive dialog between vendors and consumers.     

Towarm A Theory of is Marret Potential With Reference to Hotel and Restaurant Firms

This article analyses the internal and external structure of the consumption of services qualitatively and quantitatively. It briefly discusses the role that some factors play in deciding consumption structure and uses five computer programmes of regression analysis to fit nine regression equations by selecting 204 groups of statistical data as sample data. With quantitative analysis, it selects some mathematical models as the models of external or internal structure of service consumption. According to these models it is predicted that the percentage of expenditure on services in China's consumption structure in 2000 would be 24–26 per cent, if per capita GNP in China reaches 800–100s0 US dollars.     

商品房价格与我国房地产业周期发展

相对持续高涨的房价,我国城市居民购房能力萎缩。房地产业连续9年的快速增长,使其到了发展的巅峰。发展过热的争论和投资过快引发的经济问题,实际是房地产业周期性发展规律的必然表现。房地产业周期性发展的拐点近年将会出现,未雨绸缪应引起高度重视。     

Farmers’ risk preferences and their climate change adaptation strategies in the Yongqiao District,China

Farmers’ risk preferences play an important role in agricultural production decisions. This study characterizes risk preferences among farmers in Yongqiao and determines how these risk preferences are related to their choices regarding climate change adaptation strategies. We find that most farmers in the study area were aware of climate change. They were taking measures to protect their livelihoods against perceived changes to the local climate. The risk experiment result shows that the representative subject was risk averse, and women were more risk averse than men. The relationships between farmers’ risk preferences and different climate change adaptation choices were different. Farmers’ risk aversion was negatively and significantly related with adaptation strategies on planting new crop varieties and adopting new technology, but it had a significantly positive effect on purchasing weather index crop insurance. The results also indicate that the level of education, farming experience, farm size, household income and perception of climate change impacts influence farmers’ adaptation decisions.     

Performance measurement,expectancy and agency theory: An experimental study

Theoretical analyses of (optimal) performance measures are typically performed within the realm of the linear agency model. This model implies that, for a given compensation scheme, the agent’s optimal effort is unrelated to the amount of noise in the performance measure. In contrast, expectancy theory as developed by psychologists predicts lower effort levels for noisier performance measures. We conduct a real effort laboratory experiment and find that effort levels are invariant to changes in the distribution of the noise term. This suggests that enriching the economic model commonly applied within this area by including an expectancy parameter is not needed.     

恩格尔定律:理论与检验

恩格尔系数作为衡量居民生活水平的重要指标,其理论基础是恩格尔定律。作为实证性定律,恩格尔定律并没有严格的理论推理,其在我国的应用也受到一些质疑。本文基于效用函数假设和马斯洛层次需求理论,对恩格尔定律进行了理论推导;并利用省际面板数据(1981～2010)对模型进行了检验,结果表明恩格尔定律在我国是成立的。因此,使用恩格尔系数评价和比较我国居民生活水平是可靠的。     

中国省会城市职能结构特征的比较研究

从城市职能结构类型、发展阶段和效益三方面比较分析了我国省会城市职能结构的特征,结论如下:①在省会城市中,制造业和建筑业职能仍然占据重要地位,科教文卫、行政、金融保险业、房地产业等职能地位亟待提升.②84.62%的省会城市第三产业比重相对于第二产业比重比率稳步上升.③省会城市职能结构效益整体状况得到提高,高效益城市所占比例增加,低效益城市所占比例减少.从变化趋势类型来看,效益上升型城市所占比例居于第二位,效益下降型城市所占比例最低,这也验汪了省会城市职能结构效益趋于提升的态势.     

Marketing Package Holidays

Package holidays form a significant part of tourism and are a comparatively recent one too. This article examines some of the marketing implications. It argues that the package tour operators have created a distinct special kind of tourism product which has been responsive to the marketing techniques available to manufacturers of consumer goods.
