Bidding for an optimal portfolio of keywords in sponsored search advertising: From generic to branded keywords
No full textInternational audienceWith the increasing prominence of digital media, retailers attempt to attract consumers to their websites by investing in sponsored search advertising. However, due to stiff competition among retailers, sponsored search advertising can be expensive. This paper develops a multi-period, dynamic programming model that provides a retailer with an optimal portfolio of generic and branded bids. We model two critical aspects of consumer search behavior: (i) the spillover effect of generic searches leading to branded search arrivals in subsequent periods and (ii) the memory effect that leads to a decline of consumer awareness of a brand over time. We find that the retailer can effectively shuffle his investments on generic and branded keywords depending on several consumer parameters, e.g., awareness level, brand retention and reservation price variances. We develop a bidding policy framework to highlight the shift in bid shares from generic to branded at different levels of consumer awareness. We find that harnessing the benefits of spillover from generic to branded keywords allows the retailer to save on generic bids at higher awareness and retention levels and lower variance in consumers’ reservation prices. Further, we extend our model to different consumer purchase situations/ product classifications, viz., Convenience, Shopping and Specialty purchasing. Our analysis suggests prevalence of generic bids for certain purchase/product situations, whereas branded bids remain salient in other situations

No full textInternational audienceThe barefoot entrepreneurship literature rarely acknowledges the role of space in the development of informal economic activities. However, the concept of liminal space, defined as a place of transition and largely discussed in geography, can provide a new conceptual lens through which the trajectories of barefoot entrepreneurs can be viewed. This interdisciplinary research leverages this perspective to raise the following question: How do barefoot entrepreneurs experience liminal spaces to engage in informal economic activities? To answer this question, this article explores how 10 homeless youths in New York City panhandle, steal, deal and prostitute themselves to survive. Drawing on a four-year ethnography and the use of geographic methods, we explain how these barefoot entrepreneurs experience liminal spaces. More precisely, we underline how these spaces are ambivalent places of becoming: on the one hand, they support the development of barefoot entrepreneurship; but on the other hand, they lead to 'entrepreneurial traps' in the sense that these activities tend to increase the entrepreneurs' marginality. Based on these results, we contribute to the literature on barefoot entrepreneurship, and to a better understanding of the implication of liminal spaces in entrepreneurial dynamics
The Impact of Speed Variations on Individuals’ Emotional Journey During Post-Merger Integration
No full textInternational audienceTo investigate the link between speed of integration and organization members’ emotional experiences during post-merger integration, we undertook a 30-month, qualitative research project of two merging organizations. Using multiple sources of data, including 53 semi-structured interviews, we were able to identify the periods in which managers chose to accelerate and decelerate speed of integration. Hereby we offer a novel empirical demonstration of the variations in the speed during the integration process. We then describe and analyze the emotional consequences and outcomes of such changes in speed. This analysis resulted in the development of a comprehensive process model elucidating how variations in the speed of PMI affect emotional reactions through sensemaking (‘rationalizing’ and ‘senseseeking’) and sensegiving practices (‘sensehiding,’ ‘sense reversal,’ and ‘sense symbolization’)

The Role of Leadership Values and Communication in the Process of Change Towards Sustainability
No full textInternational audienceLiterature has given significant attention to how leadership values relate to sustainability practices. However, it takes a holistic approach to investigate how leadership values can translate to employees achieving value congruence and influencing employees' sustainability-related change readiness. This article presents a framework that takes a holistic approach to examine the role of communication in the relationship between leadership values and employees' acceptance of change toward sustainability practices. The authors carry out a qualitative synthesis of the literature, including 111 articles revealing several findings. First, different leadership values influence various sustainability practices, including social, economic, and environmental. Second, communication-oriented to reaching understanding moderates the relationship between leadership values and change toward sustainability practices. Third, the ability of leaders to influence sustainability-related change through values depends on their organisation's cultural orientations, particularly power distance. This article adds value to change management literature directed at sustainable development by presenting a framework to guide leaders in reaching mutual understating and value congruence with their employees to influence their readiness and acceptance of the change toward sustainability practices

Behavioural Aspects Behind the Growth of Fund Families
No full textInternational audienceStandard portfolio theory predicts that investors should invest in diversified portfolios, whatever their risk aversion. The asset management industry, however, is characterized by a lot of differentiated investment funds advertised to investors. This is inconsistent with the predictions of standard portfolio theory and standard rationality assumptions. Apart from the recent inflation of funds there exists also an increase of fund families, which is inconsistent with portfolio theory. The number of funds managed by managing companies has increased tremendously. The paper aims at providing an explanation based on behavioural aspects as documented by the behavioural economics literature. We focus on the flow-performance relationship and show how the convexity of the flow-performance relationship creates incentives for management companies to inflate the family of funds offered
