Do customers increase or decrease their spending in response to the introduction of an informational website? To answer this question, this study considers the effects of the introduction and use of an informational website by a large national retailer on offline customer buying behavior. More specifically, we study a website's effects on the number of shopping trips and the amount spent per category per shopping trip. The model is calibrated through the estimation of a Poisson model (shopping trips) and a type-II tobit model (the amount spent per category per shopping trip), with effect parameters that vary across customers. For the focal retailer, an informational website creates more bad than good news; most website visitors engage in fewer shopping trips and spend less in all product categories. The authors also compare the characteristics of shoppers who exhibit negative website effects with those few shoppers who show positive effects and thus derive key implications for research and practice.  相似文献

Although charismatic leadership theorists have long argued that leader–follower value congruence plays a central role in the development of charismatic relationships, few studies have tested this proposition. Using data from two studies involving a total of 329 CEOs and 1807 members of their top management teams, we tested the hypothesis that value congruence between leaders and their followers is empirically linked to follower perceptions of the charisma of their leader. Consistent with a relational perspective on charismatic leadership, strong support was found for the hypothesis that perceived value congruence between leaders (CEOs) and their followers (members of their top management teams) is positively related to follower perceptions of the degree of charisma possessed by the leader. Conversely, only limited support was found for the hypothesis that actual value congruence is linked to perceptions of charismatic leadership. Implications of these findings for research and practice are discussed.  相似文献

There are important synergies for the next generation of ethical leaders based on the alignment of modified or adjusted mental models. This entails a synergistic application of moral imagination through collaborative input and critique, rather than “me too” obedience. In this article, we will analyze the Milgram results using frameworks relating to mental models (Werhane et al., Profitable partnerships for poverty alleviation, 2009), as well as work by Moberg on “ethics blind spots” (Organizational Studies 27(3):413–428, 2006), and by Bazerman and Chugh on “bounded awareness” (Harvard Business Review, 2006; Mind &; Society 6:1–18, 2007) Using these constructs to examine the Milgram experiment, we will argue that the ways in which the experiments are framed, the presence of an authority figure, the appeal to the authority of science, and the situation in which the naïve participant finds herself or himself, all create a bounded awareness, a narrow blind spot that encourages a climate for obedience, brackets out the opportunity to ask the moral question: “Am I hurting another fellow human being?” and may preclude the subject from utilizing moral imagination to opt out of the experiment. We will conclude that these forms of almost blind obedience to authority are correctable, but with difficulty. We will argue that linking the modification of mental models to an unbinding of awareness represents an important synergistic relationship and one that can build effectively on the lessons learned from our experience with moral imagination.  相似文献

The dominant perspective on organizational buying behavior suggests that buyers tend to rely on objective criteria when making product choice decisions and that the potential influence of subjective cues, such as brands, on buyer decision making decreases with increasing risk. An alternative perspective, confirmed in this study by in-depth interviews with various managers, suggests that brands serve as a risk-reduction heuristic, whereby the influence of brands on decision making increases as a function of risk. Building on risk and information processing theories, this research builds on these complementary perspectives to propose that risk and brand sensitivity relate in a U-shaped manner, where brand sensitivity is highest in relatively low- or high-risk situations. The results of scenario- and survey-based field studies—involving 206 and 180 members of buying centers, respectively—suggest that both perspectives have merit and support the proposed nonlinear relationship. Moreover, the findings reveal that the risk-brand sensitivity relationship is moderated by competitive intensity, such that the linear (negative) and quadratic (positive) effects are stronger when competitive intensity is low.  相似文献

Because of the inconsistency in the findings from past decades of research and the lack of consensus regarding the relationship between advertising exposure and cigarette consumption, the large body of extant research on the effectiveness of cigarette advertising has generated equivocal conclusions on this subject. Therefore, we conducted a comprehensive meta-analysis of cigarette advertising research to determine what impact, if any, cigarette advertising has on cigarette consumption. Unlike previous attempts to synthesize the cigarette advertising literature, this study examined three specific levels of the criterion (i.e., initiation, continuation, and brand behavior) rather than examining only aggregate consumption.  相似文献

This article explores the hypothesis that third parties are motivated to seek information about agents who have behaved unethically in the past, even if the agent and available information are irrelevant to the third parties’ goals and interests. We explored two possible motives for this information seeking behavior: deonance, or the motive to care about ethics and justice simply for the sake of ethics and justice, and distrust-based threat monitoring. Participants in a consumer decision task were found to seek out information about an agent who had behaved unethically even when the agent was explicitly excluded from the task; there were no intentions to purchase from the agent; performance expectations for the agent’s product were low; the information that could be sought was non-diagnostic, redundant or irrelevant to an ethical judgment; and alternatives in the market offered as good or better value as the unethical agent. Critically, this information seeking took place even when the observer could disengage from and was not vulnerable to the agent. The findings are discussed in terms of third party information seeking and its effects on ethical behavior in the marketplace.  相似文献

This paper focuses on the innovative actions of entrepreneurs, namely their tendency to reveal the intellectual capital that results from their research efforts either in the form of public knowledge (publications) or private knowledge (patents). Using data collected by the National Research Council within the US National Academies from their survey of firm’s that received National Institutes of Health phase II Small Business Innovation Research awards between 1992 and 2001, we find that entrepreneurs with academic backgrounds are more likely to publish their intellectual capital compared with entrepreneurs with business backgrounds, who are more likely to patent their intellectual capital. We also find that, when universities are research partners, their presence complements the tendencies of academic entrepreneurs but does not offset those of business entrepreneurs.  相似文献

The extraordinary growth of the Irish economy since the mid-1990s—the ‘Celtic Tiger’—has attracted a great deal of interest, commentary and research. Indeed, many countries look to Ireland as an economic development role model, and it has been suggested that Ireland might provide key lessons for other EU members as they seek to achieve the objectives set out in the Lisbon Agenda. Much of the discussion of Ireland’s growth has focused on its possible triggers: the long-term consequences of the late 1980s fiscal stabilisation, EU structural funds, education, wage moderation and devaluation of the Irish punt. The industrial policy perspective has highlighted the importance of inflows of foreign direct investment, but a notable absence from the discourse on the ‘Celtic Tiger’ has been any mention of the role of new business venture creation and entrepreneurship. In this paper we use unpublished Irish VAT data for the years 1988–2004 to provide the first detailed look at national trends in business birth and death rates in Ireland over the ‘take-off’ period. We also use sub-national VAT data to shed light on spatial trends in new venture creation. Our overall conclusions are that new business formation made no detectable contribution to the acceleration of Ireland’s growth in the late 1990s, although we do find evidence of spatial convergence in per capita business stocks.  相似文献

Candidate gene studies of human behavior are gaining interest in economics and entrepreneurship research. Performing and interpreting these studies is not straightforward because the selection of candidates influences the interpretation of the results. As an example, Nicolaou et al. (Small Bus Econ 36:151?C155, 2011) report a significant association between a common genetic variant in the DRD3 gene and the tendency to be an entrepreneur. We fail to replicate this finding using a much larger, independent dataset. In addition, we discuss the candidate gene approach and give suggestions to avoid the publication of false positives.  相似文献

The literature argues that entrepreneurial intentions depend on perceptions of desirability and perceptions of feasibility. Research in other fields suggests that there will be an interaction effect between these two main antecedents of intentions, but such interaction has not been investigated in the context of entrepreneurial intentions. In this paper we explore this interaction effect in an expectancy framework, hypothesizing a negative interaction effect between perceived desirability and perceived feasibility based on regulatory focus theory. A large multi-country sample confirms this negative interaction, and suggests a novel typology of nascent entrepreneurs as natural entrepreneurs, accidental entrepreneurs, and inevitable entrepreneurs.  相似文献
