已有文献认为失败学习对企业绩效具有重要作用,但失败学习通过何种途径促进企业绩效提升的研究并不完善。基于失败学习理论,引入资源拼凑和机会识别作为中介变量,构建失败学习影响企业绩效的多路径模型,探索失败学习对企业绩效的驱动路径及内在机理。实证结果表明:失败学习对企业绩效具有显著积极作用,资源拼凑和机会识别分别在失败学习与企业绩效之间起中介作用,资源拼凑和机会识别在失败学习对企业绩效驱动过程中存在链式中介作用,战略柔性能够强化资源拼凑与企业绩效之间的关系,并正向调节资源拼凑的中介作用。研究结论拓展了失败学习对企业绩效的影响路径,对企业复苏和成长具有重要启示。 相似文献

Communication externalities in cities 总被引:2,自引:0,他引:2
To identify communication externalities in French cities, we exploit a unique survey recording workplace communication of individual workers. Our hypothesis is that in larger and/or more educated cities, workers should communicate more. In turn, more communication should have a positive effect on wages. By estimating both an earnings and a communication equation, we find evidence of communication externalities. In larger and more educated cities, workers communicate more and in turn this has a positive effect on their wages. Depending on the estimates, we find that 13 to 22% of the effects of a more educated and larger city on wages percolate through this channel. 相似文献

This paper examines the internal implications of branding within higher education, a specific context which is dominated by the co-existence of strong professional logics and identity structures. We focus on how and whether academic faculty identify with the branding practices undertaken by their respective institution. The paper proposes a communicative perspective on brand identification to understand how academic faculty relate to and make sense of the brand. The findings, from responses of 65 faculty members at five business schools, indicate widespread indifference and non-identification with brand messages. Specifically, we identify four types of disconnects between faculty members and branding practices of their respective schools, namely ambiguity, emptiness, misalignment, and irrelevance. The evidence of these disconnects, we argue, suggests that the faculty members refrain from relating the brand to their own identities. Although individuals relate to discourses around the brand, these are often not internalized and do not thereby impact on their individual identity. Rather than navigating between identity tensions, they eschew identification altogether. We contribute to research on how branding works inside contemporary organizations – including higher education - through questioning the role of identity in branding processes seen as the management of meaning. 相似文献

Order display is associated with benefits and costs. Benefits arise from increased execution-priority, while costs are due to adverse market impact. We analyze a structural model of optimal order placement that captures trade-off between the costs and benefits of order display. For a benchmark model of pure liquidity competition, we give a closed-form solution for optimal display sizes. We show that competition in liquidity supply incentivizes the use of hidden orders to prevent losses due to over-bidding. Thus, because aggressive liquidity competition is more prevalent in liquid stocks, our model predicts that the proportion of hidden liquidity is higher in liquid markets. Our theoretical considerations ares supported by an empirical analysis using high-frequency order-message data from NASDAQ. We find that there are no benefits in hiding orders in il-liquid stocks, whereas the performance gains can be significant in liquid stocks. 相似文献

In line with Kang and Herr's work (2006), this research questions the ELM's contention that celebrity credibility serves foremost as a peripheral element in a persuasive communication context. Nevertheless, in a different light to the Kang and Herr's ‘either-central-or-peripheral-role’ of a source characteristic, this research advances that celebrity credibility plays concomitantly central and peripheral roles in a persuasive message context depending on product involvement and brand-purchase motive. Particularly, this research uses the notions of ‘source internalization’ and ‘source identification’ (Kelman, 1961) to theorize that source credibility can have a concomitant dual role (peripheral and central) in a persuasion context. More precisely, this research investigates the interactive effects of source identification and internalization with product involvement as well as brand-purchase motives on consumers' attitudes and intentions. Source internalization is predicted to have persuasive effects in the contexts of high-involvement as well as informational products. Source identification is predicted to have persuasive effects in the context of low-involvement as well as transformational products. The findings of two experiments show that celebrity credibility acts through only a single route (i.e., only internalization has persuasive effects) uniformly across different product involvement levels and brand-purchase motive types. We interpret these results with the lens of the ‘match-up’ hypothesis (Kamins, 1990). 相似文献

This article investigates how uncertainty impacts the effect of monetary policy surprises on stock returns. Using high-frequency US data, we demonstrate that stock markets respond more aggressively to monetary policy surprises during periods of high uncertainty. We also show that uncertainty asymmetrically influences the transmission of positive and negative monetary policy surprises to stock market prices. The amplifying effect of uncertainty is found to be stronger for expansionary shocks than for contractionary shocks. Our robustness analysis confirms that financial uncertainty has a significant role in shaping the influence of monetary policy on the stock market. 相似文献
