An Empirical Analysis of the Extreme Cherry Picking Behavior of Consumers in the Frequently Purchased Goods Market

Extreme cherry pickers are customers who seek price deals and excessively avail themselves of deep discount offers, which generates negative profits for retailers. This study uses market transaction and primary consumer survey data to provide insights into the determinants, prevalence, and profit impacts of such behavior in the frequently purchased goods market. We find that the extreme cherry picking segment is small (about 2% of all shoppers), but its relative value varies across stores, and consumers manifest this behavior only in secondary stores. An inverse U-shaped relationship marks consumers’ opportunity costs for cross-store price search and likelihood of extreme cherry picking behavior. Finally, we also find that a loss leader promotional strategy adds to retailers’ bottom lines, despite the pure loss generated by extreme cherry pickers.     

旅游业搜索引擎营销策略研究

在当今"眼球经济"时代,相对于互联网的海量信息,消费者的注意力是相当有限的。企业吸引被信息湮没的潜在消费者的注意力已成为其竞争力的重要来源,搜索引擎营销也随之体现出巨大的商业价值。同时,互联网用户对搜索引擎的依赖程度不断加深,使得搜索引擎营销越来越受到企业的重视,也使得旅游业对互联网的依存度逐渐提高。

Accessibility of flood risk insurance in the UK: confusion,competition and complacency

Flood risk insurance can be an effective tool in assisting the restoration of damaged property after a flood event and sustaining communities through difficult times. It can also form part of a wider flood risk management strategy. In the light of recent flood events in the UK and in the context of changing property insurance markets, the universal cover previously enjoyed by floodplain residents has been called into question. Conflicting media and industry views leave the floodplain resident and the wider community in confusion. A survey of floodplain residents in England regarding their experience with flooding and flood insurance in England has been undertaken. The results reveal that some floodplain residents do indeed encounter difficulties when seeking insurance for their homes. However, despite the risk‐averse policies of some insurers, availability of insurance is still strong in both at‐risk and previously flooded locations. Success in gaining insurance may lead to complacency among residents who see no advantage in pursuing other, more costly, damage mitigation actions. As a tool in risk management, therefore, the market is prevented from realising its potential by competition, which results in a lack of a consistent approach, rewards homeowners' search strategies and reduces information flow.     

An Experimental Examination of US Individual Donors’ Information Needs and Use

This paper adopts an internet‐based experiment to investigate whether and how individual donors use nonprofit organizations’ financial and nonfinancial information when making their donation decisions. Using undergraduate students in the United States (US) to proxy for individual donors, our results indicate that individual donors are more likely to acquire nonfinancial information, such as nonprofit organizations’ goals, outcomes, programs and missions, than financial information. Donors integrate nonfinancial information into their decisions as their actual donations are significantly correlated with such information. Our results also indicate that while individual donors acquire financial efficiency measures, including the program expense ratio and fundraising expense ratio, they do not seem to integrate such information into their decisions as their actual donations are not significantly correlated with the efficiency information. This study contributes to the nonprofit literature and research domain focusing on charitable giving and donor preferences.     

The value of commuting time in an empirical on-the-job search model – an application based on moments from two samples

This article estimates the Value of Commuting Time (VOCT) among Swedish males in an empirical on-the-job search model. It uses a large sample of employee-establishment linked data obtained from administrative registers. The sample lacks information on mode choice for the journey to work. We therefore estimate a mode choice model on another sample and use this model to link the administrative data to the relevant set of travel times, costs and distances. The VOCT is found to be 1.8 times the net hourly wage rate in the sample. The relatively high estimate results from a high VOCT among cohabiting men.     

Exploring the relationships between knowledge sources in the innovation process: evidence from Finnish innovators

Innovation is a costly, risky, and uncertain process, and one of its most central components is knowledge as has been emphasised in the innovation literature. Notably, such knowledge tends to be distributed across different internal and external sources. That is, innovation processes involve diverse relationships between knowledge that originates from a myriad of different sources such as customers, suppliers and universities. While such relationships are distinctive to modern – distributed – innovation processes, little is still known about their implications on the search for new knowledge. This paper proposes that since the innovation process is inherently an uncertain and costly activity, a deeper understanding on the relationships between knowledge sources can help firms to better master the risks and costs related to their search activities. In other words, given that not all knowledge is equally combinable with each other, it claims that complementarities among knowledge sources increase the likelihood (over non-complementarities and substitutes) that such sources encompass mutually combinable knowledge, and hence decrease the uncertainties, risks and costs involved in distributed innovation processes.     

Emerging search regimes: measuring co-evolutions among research,science, and society

Scientometric data is used to investigate empirically the emergence of search regimes in biotechnology, genomics and nanotechnology. Complex regimes can emerge when three independent sources of variance interact. In our model, researchers can be considered as the nodes that carry the science system. Research is geographically situated with site-specific skills, tacit knowledge and infrastructures. Second, the emergent science level refers to the formal communication of codified knowledge published in journals. Third, the socio-economic dynamics indicate the ways in which knowledge production relates to society. Although biotechnology, genomics and nanotechnology can all be characterised by rapid growth and divergent dynamics, the regimes differ in terms of self-organisation among these three sources of variance. The scope of opportunities for researchers to contribute within the constraints of the existing body of knowledge are different in each field. Furthermore, the relevance of the context of application contributes to the knowledge dynamics to various degrees.     

电子采购中组合多属性招投标的优化研究

由于物品之间存在互补效应,往往投标者会将几个标的物作为一个组合标进行投标。这一方式在传统的多物品电子采购中仅仅从价格或成本的考虑来确定竞胜标,因而无法同时解决采购中的多属性问题。在网络技术的支持下,这种组合招投标的采购模式已经成为可能。通过以最大化采购方的效用为目标建立数学模型,并运用禁忌搜索算法进行求解,可满足多属性决策的招投标方法要求,解决电子采购中对于具有互补效应的多物品多属性的竞胜标确定问题。但由于问题自身的复杂性,对此类问题的研究处于起步阶段,对于多属性间的关系研究,多属性评价方法的改进,以及求解方法的研究与计算效率的提高等问题还有待于进一步解决。
