While decision makers in organizations frequently make good decisions rooted in stable and consistent preferences, such consistency in outcomes is not always the case. In this study, we adopt a psychological perspective of judgment to investigate managers' erratic strategic decisions, which we define as a manager's inconsistent judgments that can shape the direction of the firm. In a study of 2,048 decisions made by 64 CEOs of technology firms, we examine how both metacognitive experience and perceptions of the external environment (hostility and dynamism) could affect the extent to which managers make erratic strategic decisions. The results indicate that managers with greater metacognitive experience make less erratic strategic decisions. The results also indicate that in hostile environments managers make more erratic strategic decisions. But contrary to our expectations, in dynamic environments managers make less erratic strategic decisions. Similarly, hostility and dynamism interact in their effect on erratic strategic decisions in that the positive relationship between environmental hostility and erratic strategic decisions will be less positive for managers experiencing high environmental dynamism than those experiencing low environmental dynamism. These results have important implications for strategic decision‐making research. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

This paper investigates whether and to what extent group identity plays a role in peer effects on risk behaviour. We run a laboratory experiment in which different levels of group identity are induced through different matching protocols (random or based on individual painting preferences) and the possibility to interact with group members via an online chat in a group task. Risk behaviour is measured by using the Bomb Risk Elicitation Task and peer influence is introduced by giving subjects feedback regarding group members’ previous decisions. We find that subjects are affected by their peers when taking decisions and that group identity influences the magnitude of peer effects: painting preferences matching significantly reduces the heterogeneity in risk behaviour compared with random matching. On the other hand, introducing a group task has no significant effect on behaviour, possibly because interaction does not always contribute to enhancing group identity. Finally, relative riskiness within the group matters and individuals whose peers are riskier than they are take on average riskier decisions, even when controlling for regression to the mean.  相似文献

The article investigates whether the history of individuals’ spatial relocation has an impact on their propensity to perform an entrepreneurial entry and post-entry performance of firms they start. By looking at entrepreneurs in the IT services sector in Swedish non-core regions between 1991 and 2010, the article investigates the interaction between individuals’ embeddedness in local networks and their exposure to external knowledge accumulation opportunities across different geographical settings, as well as its impact on their entrepreneurial activities. The results of the analysis suggest that individuals with broad spatial relocation histories are more likely to start IT firms in non-core regions, which, in turn, may be expected to survive longer. It is, therefore, claimed that non-local knowledge accumulated through spatial relocation is an important complement to embeddedness in local networks in non-core regions. This complementarity is further related to the evolution of the IT services sector over time.  相似文献

This study fills an important gap in the literature by exploring the effects of the attractiveness of a non-monetary promotion with premiums on credit card purchase intention and brand selection. Two experimental studies involving 386 undergraduates were done. Non-monetary sales promotions with attractive premiums have a positive influence on the credit card purchase intention, compared to non-monetary sales promotions with unattractive premiums. On brand choice, non-monetary sales promotions with attractive premiums increase the likelihood of brand choice promoted. Premiums attractiveness is an important variable in the evaluation of a promotional offer that aims to increase the intention purchase and motivate the selection of brand. This study helps managers in choosing the types of premiums that are valued by consumers in a promotion. Most of the studies explore monetary promotions, while this study contributes to literature by exploring the gap about the effects of non-monetary sales promotions on purchase intention and brand selection, especially in the bank services environment.  相似文献

It is estimated that financial services comprise around 15% of the global economy. From the supply side, one key to meeting this demand is being able to educate and certify the people who provide these services. With the advent of the internet and related technologies, the ability to deliver financial services education synchronously to both online and on-campus attendees has become a viable alternative to pure face-to-face or pure online asynchronous education. Nonetheless, one question remains: can virtual technology deliver comparable quality of financial services educational experience as face-to-face teaching? It is this question our paper addresses using the theory of transactional distance. The theory of transactional distance postulates that for optimal learning, the cognitive gap between instructor(s) and learner(s) needs to be minimized. We explore how transactional distance in financial services education varies by attendance modality (in-class, online and mixed) in a synchronous, web-extended classroom. The implications for managers and researchers are explored.  相似文献

This study introduces the concept of attractiveness similarity, empirically examines its main effect and whether it moderates the effect of endorser attractiveness on consumer responses to advertising. The results show a positive main effect of attractiveness similarity over and above the mere effect of endorser attractiveness. In addition, a consistent moderating effect of attractiveness similarity on the effect of endorser attractiveness emerges: attractiveness similarity buffers against the less positive effects of lower levels of endorser attractiveness (i.e., it compensates for lower levels of endorser attractiveness). Overall, these findings reveal attractiveness similarity as a new variable in endorser advertising, which has important managerial implications. Advertising campaigns employing averagely attractive endorsers should pay special attention to attractiveness similarity.  相似文献

Five billion people in the world do not have the kind of ledgers that provide the documented information that allows them to transfer, partition, and aggregate assets and talents in such a way that they can be scaled up, secure investment, guarantee credit, certify reputation, and capture abstract surplus value. The difficulty that most people have in making combinations is a major cause of global inequality and unnecessary poverty.  相似文献
