The quantitative assessment of the financial impact of unexpected events is the realm of the “event study.” We examine how CEOs, boards, and public policymakers can utilize event studies to inform and improve their decision making. The breadth of application of event studies is surprisingly broad and ranges from situations involving the death of a CEO to emergency product recalls. We present illustrative event studies for two Steve Jobs-related announcements concerning his health in order to demonstrate both the potential and limitations of the technique. 相似文献

This article takes as its point of departure the view that technological change is a social process involving negotiations between networks of players. The paper aims to inform the debate on technology management by identifying the dynamics of spaces and occasions where technological change is addressed and politicized. It takes as its focus the development of the information technology (IT) systems for manufacturing, known as Enterprise Resource Planning (ERP) systems in Denmark. These systems, which started out 30 years ago as a visionary concept in the US, are now in daily use in Danish firms. This technology has been moulded by the twin forces of stability and negotiability, with the interplay of supplier and user constellations set out in the context of the relative stability of company social systems. The article discusses three spaces within which the social shaping of IT takes place: the user producer segments, the company internal scene and technological context with the competing pull of mass production of software and company customization. Strategic possibilities are shown to be of a shifting nature with the occasions shaping technology appearing both as ruptures and emergent options which are restricted by the strategies of participating players. Consequently no single player has a natural position to manage technological change and it is suggested that technology strategies should be subject to open debate and exchange of experiences from a multiplicity of positions and perspectives. 相似文献

Purchases of voluntary carbon offsets (VCOs) are growing tremendously. At the same time, the number of activities and products for which VCOs are available is increasing. Experts discuss whether offering VCOs is exclusively associated with positive effects on the environment or if it instead may lead to increased consumption of environmentally critical products. To date, empirical evidence on such adverse effects is scarce. Therefore, this study uses a randomized controlled trial design to investigate how the availability of VCOs affects consumers' choices for environmentally critical products. The results suggest that when VCOs are available, the likelihood of environmentally critical consumption increases. From a mental accounting perspective, our findings support the theoretical rationale of VCOs as an instrument for moral licensing. Additionally, our results indicate that individuals tend to trivialize the harmfulness of the environmentally critical product and overestimate the effectiveness of VCOs for environmental protection, which we consider strategies for reducing cognitive dissonance and guilt. 相似文献

Steve Jobs of Apple, Inc., is one of the best known CEOs in the world, and some stock analysts have termed him “irreplaceable.”
Using conventional event study methods, we test the magnitude of these announcements on Apple’s share price and its market
capitalization. We focus upon nine “events” between 2004 and 2009 in which new information about Mr. Jobs’ health was flushed
into the marketplace, on occasion by Apple itself, but more often by the commentary and speculations of media observers, stock
analysts and bloggers. We find that the impact of these announcements upon Apple share prices is mixed, usually modest, and
disappears over time. We conclude that Jobs’ health has an impact on Apple’s share price and market capitalization, but that
impact is not always negative and not nearly as large as many observers apparently believe. 相似文献

This contribution aims at analysing IPSERA, an active international network of academics, consultants and practitioners in the area of purchasing and supply management. The association shows to be a community of people who like to work together. The long-term view and strategy, the decision process and the degree of innovativeness are viewed by its members as positive, albeit seemingly unfamiliar. With respect to a general factor reflecting ‘general satisfaction’, no bias in the replies could be found, caused by differences in background. With respect to some more detailed aspects of the organisation, professional background and national cultural background caused some bias in the replies. 相似文献

Purpose: The authors examine whether motivational and cognitive causes that explain tariff choice biases in business-to-consumer (B2C) settings also hold in business-to-business (B2B) markets. Opposed to prior B2C research that is dominated by individual decision making, the study proposes role effects in buying centers influence the exploration of tariff choice and tariff choice biases in B2B settings. Originality: A rich body of research into biased tariff choices, especially flat-rate biases, exists for B2C markets, yet a dearth of research marks tariff choice behavior in B2B settings. This study is the first one on tariff choice especially dedicated to B2B settings. Methodology and Findings: The findings from transactional and survey data pertaining to a mobile phone service provider reveal that tariff choice biases also occur in B2B markets. Seventy-nine percent of all tariff choices among decision makers are biased; 73 percent are due to the flat-rate bias. The (mis-)judgment effect, the insurance effect, and the convenience effect significantly influence tariff choice and the flat-rate bias. Research Implications: The authors provide a flowchart of strategies that structures the practical implications. Based on this flowchart, they propose that mobile phone service providers should undertake a flat-rate preference strategy, because B2B customers may accept the flat-rate bias to profit from the insurance effect. The authors argue that following a flat-rate preference strategy is advisable, because turnover can be protected entirely while the vulnerability of that strategy is low. 相似文献

As workers age, they acquire valuable experience even while their physical abilities eventually decline. Bosses/managers have
the potential to alter the complex relationships between experience and declining physical abilities for better, or for worse.
We examine the performances of 39,698 Major League baseball players in the 20th century and find that: (1) hitting performance
peaks at age 30, base stealing at 27, and pitching at 34; (2) except for pitching, even experienced managers usually have
little influence on player performance, or that influence is negative. In general, managers and coaches play limited roles
in occupations where natural ability trumps other factors. 相似文献

The concept of tourism‐led socio‐economic development is neither new nor peculiar to South Africa. This study draws on the international experience of the Malindi‐Mombasa coastal development corridor in Kenya, the Goa Coast of India, the Kulu Valley and Bhutan in the Himalayas, the Gambia, Dominica, Belize and the Maldives. It assesses the results achieved in these tourism programmes against the strategic objectives of those South African SDIs that place a heavy emphasis on the country's tourism potential. The SDIs, as described elsewhere in this collection, represent a new paradigm adopted by the South African government, aimed at moving away from a protected and isolated approach to economic development, towards one in which international competitiveness, regional cooperation and a more diversified ownership base are paramount. The key objectives of the tourism‐led development corridors, including the Wild Coast and Lubombo SDIs, are to generate sustainable economic growth and development; generate sustainable long‐term employment creation; maximise the extent to which private sector investment and lending can be mobilised into the process; change the ownership base of the industry so that people previously excluded from the mainstream of the economy by discriminatory practices can play a meaningful role as workers, managers and owners of new tourism enterprises; and to exploit the opportunities that arise from new tourism and ecotourism developments for the creation of upstream and downstream business opportunities, especially small businesses owned by previously marginalised groups. 相似文献
