Whose experience matters in the boardroom? The effects of experiential and vicarious learning on emerging market entry

Using an organizational learning perspective, we develop arguments about vicarious learning through board interlocks and its relation to experiential learning. Although it is well established that firms learn from board interlocks, little attention has focused on which types of interlocks are most consequential and why. We distinguish between the relative advantages of various tie attributes such as experience, authority, and credibility and argue that these distinctions lead to measureable differences in learning outcomes. We further demonstrate that whether vicarious learning substitutes or complements focal firm experiential learning depends upon the type of interlock involved. After accounting for the endogeneity of ties, we find support for our framework in a longitudinal analysis of foreign investments by German firms in emerging economies between 1990 and 2003.

Learning by supplying

Outsourcing in many industries has advanced beyond simple component supply to encompass manufacturing of entire products, often by suppliers in emerging economies. Understanding the evolving role and capabilities of suppliers in global supply chains is thus a pressing strategic issue for suppliers and customers alike. We analyze a novel panel dataset of supply relationships in the mobile telecommunications industry to answer the following questions: What factors contribute to a supplier's ability to build technological and market capabilities? Does it matter to whom the firm supplies? Is involvement in product design important, or is manufacturing the key to learning? Do the same types of relationships that support technological innovation also facilitate successful introduction of own‐brand products, or does this require a different “locus” of learning?

When hubs forget,lie, and play favorites: Interpersonal network structure,information distortion,and organizational learning

The interpersonal network structure of an organization directly influences the diffusion and recombination of ideas and can thus facilitate or impede organizational learning. Most interpersonal networks have ‘hubs’—individuals who have significantly more connections than does the average member. This raises important questions about how hubs influence organizational learning outcomes. Does the presence of hubs improve or impair performance? What happens if hubs forget or misrepresent information that is transmitted through the network? Using simulation models, we find that moderately hubby networks outperform both very hubby and democratic networks. We also find that moderate amounts of information omission or misrepresentation can be surprisingly beneficial to performance, though the patterns of their effects are strikingly different.

When bad news is sugarcoated: Information distortion,organizational search and the behavioral theory of the firm

Most work in strategy and organization theory assumes that performance feedback is straightforward to interpret and truthfully reported. We raise the following question: How might the systematic distortion of negative performance information affect organizational learning and future performance? We formulate a model where (1) members do not always report the truth about what they know about their performance level, especially when performance is below aspiration and (2) their propensity to distort information is subject to social influence. We find that organizations that are characterized by a high level of information distortion tend to perform more poorly but that the effect of a low rate of sugarcoating may, in some conditions, be more benign than the literatures seem to suggest.

Overcoming localization of knowledge — the role of professional service firms

The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

基于2DPCA和稀疏表示的目标跟踪算法

针对现有的目标跟踪算法难以适应由光照、遮挡以及姿态变化引起的目标外观变化的问题,提出了一种基于二维主成分分析（2DPCA）和稀疏表示的目标跟踪算法。该算法采用2DPCA方法和稀疏表示建立目标外观模型,降低了目标模板的维数,并通过引入增量子空间更新方法对目标模板进行在线更新,降低了算法对存储空间的要求,提高了目标外观描述的准确性。仿真实验表明,在目标出现较大形变、部分遮挡和光照变化的情况下,该算法仍能保持较高的跟踪精度,具有较强的鲁棒性。     

Knowledge exchange and knowledge protection in interorganizational learning: The ambidexterity perspective

Are knowledge exchange and knowledge protection conflicting or complementary? Although facilitating knowledge exchange and protecting core proprietary knowledge are important in interorganizational learning, extant studies often regard them as conflicting activities. Few studies have discussed the mechanisms that can help firms achieve both. In this current study, we extend the concept of ambidexterity to the interorganizational learning context and suggest several mechanisms that can enhance knowledge exchange and knowledge protection simultaneously. We conducted a survey and the empirical results reveal that experience sharing and shared interpretation are positively associated with knowledge exchange success. Hostage arrangement enhances the level of knowledge protection, whereas reciprocal investment has no effect on knowledge protection. Furthermore, ambidexterity (the product term of knowledge exchange success and knowledge protection) significantly affects the performance of a firm. Finally, we discuss the implications of this research and offer suggestions for future research.

The positive effects of relationship learning and absorptive capacity on innovation performance and competitive advantage in industrial markets

This study utilized structural equations modeling (SEM) to explore the positive effects of relationship learning and absorptive capacity on competitive advantages of companies through their innovation performances in Taiwanese manufacturing industry. The results of this study showed that relationship learning and absorptive capacity positively influence upon innovation performances of companies, and further have positive effects on competitive advantages of companies. In addition, this study divided the sample into three groups by the levels of relationship learning and absorptive capacity and found that there was a significant difference of innovation performance among these three groups: ‘Highly Capable Companies’, ‘Medially Capable Companies’, and ‘Lowly Capable Companies’. It is important for ‘Lowly Capable Companies’ to increase both of their relationship learning and absorptive capacity to enhance their innovation performances.     

The effects of strategic and market complementarity on acquisition performance: evidence from the U.S. commercial banking industry, 1989–2001

Most traditional research on mergers and acquisitions tends to focus on the role of similarity in explaining acquisition performance. While scholars have recently begun to examine acquisition complementarity, there is still little evidence concerning how complementarity influences acquisition performance. Further, previous research has not drawn the connections between related contexts and the potential benefits from complementarity. In this article, we move the study of acquisition complementarity forward by investigating the effects of strategic and market complementarity on acquisition performance in the context of related horizontal acquisitions. We also propose that two key attributes of acquirers—strategic focus and out‐of‐market acquisition experience—will moderate this relationship. We investigate our research questions in the context of all 2,204 acquisitions made by publicly traded U.S. commercial banks during the 12‐year period from 1989 to 2001. Our findings are generally supportive, suggesting complementarity is an important antecedent of acquisition performance, and raising important issues on the nature of acquisition research in general.
