Based on a longitudinal case study of four interorganizational product development collaborations, this paper identifies a lure to cross‐functional integration that has hereto been neglected. In particular, findings suggest that when the buyer firm separates the Research and Development (R&D) Department from the Procurement Department, the two departments play a good cop–bad cop strategy toward the supplier. Thereby, they are able to foster a high level of goodwill trust between R&D personnel of the collaborating firms, while procurement personnel maintain a high level of formal control. Using an intricate sample design with polar cases, the study shows that cross‐functional integration of the two departments hampers interorganizational goodwill trust at the benefit of formal control. The findings offer a way forward for managers seeking to reap the benefits of collaboration, while limiting their exposure to the associated risks. 相似文献

Research Summary: A learning‐by‐hiring approach is used to scrutinize scientists' mobility in relation to the recruiting firms' subsequent innovation output. Our starting point is that among firm hires, individuals with university research experience—hired from universities or firms—can be particularly valuable. However, conflicting institutional logics between academia and industry makes working with academic scientists challenging at times for firms. We suggest two solutions to this difficulty: hiring “ambidextrous” individuals with a mix of experience of university research and working for a technologically advanced firm, and a strong organizational research culture in the recruiting firm reflected by the presence of a scientist on the top management team. We track the mobility of R&D workers empirically using patent and linked employer‐employee data. Managerial Summary: An important way to make organizations more innovative is hiring individual researchers with the right types of skills and experience. We show that individuals with university research experience beyond their final degree are particularly likely to help boost firm‐level innovation output after hiring compared to R&D workers with other types of skills and experience. However, to obtain good returns to innovation from hiring such individuals, firms need a university research–friendly organizational culture when hiring individuals with university research experience, from either firms or academia. 相似文献

The R&D management paradigms of research and technology organizations (RTOs) have been discussed in the past. Academics have analysed their strategic challenges in view of the new demands posed by new competitive environments for their SME clients. New innovation models proposed recently have captured the attention of policy makers. The objectives of this paper are to analyse these models in the case of a particular model of RTO: the R&D units in the Basque Country in Spain, launched with the aim of improving R&D and technology transfer efficiency. This paper is based on an empirical study of a group of specialized RTOs (R&D units) and its objective is to analyse a new paradigm of RTO and propose a model to identify the critical elements that influence performance and strategic alignment between R&D performers (RTOs) and their partners (in most cases SMEs). 相似文献

Studies examining the direct effects of employee demographic differences on grievance filing have yielded mixed results. Moreover, little is known regarding the possible moderating effect that such differences might have on the link between workplace adversity and grievance filing. Using a sample of 866 blue‐collar workers drawn from four unions, we examine the potential moderating effects of gender and race/ethnicity. Our findings suggest that while gender and ethnicity are not significantly associated with perceptions of workplace adversity, grievance filing in response to certain forms of adversity is amplified among women (as compared to men) and among African Americans and Hispanics (as compared to whites). The meaning and implications of these findings are discussed. 相似文献

Research summary: We show that private equity ownership (“PE backing”) of the acquirer is a signal of deal quality in cross‐border takeovers. As such, PE‐backed acquirers experience higher announcement returns in cross‐border takeovers, but only if targets are in poor information environments. We show that PE backing is a positive market signal because of PE firms' experience and networks that result from prior deals in target countries. We document that the market correctly anticipates that operating performance of PE‐backed acquirers increases as a result of cross‐border mergers and acquisitions (M&A). Managerial summary: We study cross‐border acquisitions by acquirers that are partially owned by private equity firms (“PE backing”). Cross‐border acquisitions are challenging as acquirers often have little information about targets. We document that investors react positively to cross‐border deals of PE‐backed acquirers—their stock prices increase upon deal announcements. However, this is only the case if targets are in countries with poor information environments. This is because PE backing allows acquirers to access PE firms' deal experience and networks. This makes it easier to identify and evaluate good targets, making it more (less) likely that a deal eventually creates (destroys) value. Consistent with this, we find that earnings of PE‐backed acquirers increase after buying targets in poor information environments. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Service transition strategies of industrial manufacturers 总被引:4,自引:0,他引:4

Manufacturers are increasingly adopting service based strategies to maintain competitiveness in the face of commoditization, slower growth, and declining profitability in core product markets. The objective of this study is to explicate the transformation process towards services in more detail. We find that manufacturers develop product related services through a dedicated service division designed to exploit the commercial opportunities of servicing an installed base of equipment. At the same time, the strategy of integrated solutions is utilized to enhance the competitiveness of their core product offering under industry conditions which make it difficult to maintain competitive advantage purely through technological leadership. These logics are investigated through case studies of two industrial manufactures. 相似文献

Managing new product development (NPD) with a global point of view is argued to be essential in current business more than ever. Accordingly, many firms are trying to revitalize their NPD processes to make them more global. Therefore, examining global NPD management is one of the top priorities for research. While scholars have examined global launch management, there has been scant attention on the direct effect of global discovery management on NPD success. Therefore, this study investigates how a globally managed discovery phase enhances a firm's overall NPD success. Drawing upon the resource‐based view (RBV) and using Kotabe's ( 1990 ) generic model for market success in global competition as the overarching framework, this study examines four drivers of NPD success: global discovery management, the firm's “global footprint,” its inbound knowledge sourcing practices (i.e., “open innovation proclivity”), and nationality of the teams (i.e., “cross‐national global NPD team use”). The hypotheses are tested using a sample of 255 business units from multiple industries, headquartered worldwide, and surveyed during the 2012 PDMA Comparative Performance Assessment Study (CPAS). The PLM‐SEM analyses show that, of the four drivers examined, only global discovery management strongly influences a firm's NPD program success. The findings enhance our understanding of the particularities in global NPD. Based on the study's results, suggestions are provided as to how multinationals can leverage their international operations in the course of their front‐end activities. 相似文献

This paper advances the risk management perspective that superior social performance enhances firm value by serving as an ex ante valuable insurance mechanism. We posit that good social performance is more valuable as an insurance mechanism for firms with higher litigation risks. Moreover, value generation of corporate social performance (CSP) depends on whether a firm has gained pragmatic legitimacy (i.e., a firm's financial health) and moral legitimacy (i.e., whether or not a firm operates in a socially contested industry) among its stakeholders. We find that the value of CSP as insurance against litigation risk is practically significant, adding 2 to 4 percent to firm value. But CSP is less likely to create value if the firm is in financial distress or is operating in socially contested industries. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Entrepreneurial ventures are a key source of innovation. Nowadays, ventures are backed by a wide array of investors whose complementary asset profiles differ significantly. We therefore assert that entrepreneurial ventures can no longer be studied as a homogeneous group. Rather, we harness the inherent dichotomy in the profiles of independent VCs and corporate investors to study ventures' innovation outcomes. Our sample consists of 545 U.S. biotechnology ventures founded between 1990 and 2003 and backed by independent venture capitalists (VCs) or corporate VCs (CVC). We find CVCs' investees exhibit higher rates of innovation output, compared to independent VC‐backed peers. Moreover, the performance of CVC‐backed ventures is sensitive to their ability to leverage corporate assets, underscoring the role of CVC accessibility and FDA approval requirements as the mechanisms associated with CVC contribution.

This paper studies the cognitive processes that enable decision makers to switch between exploitation and exploration. We use functional magnetic resonance imaging (fMRI) in a sample of expert decision makers to make two main contributions. First, we identify and contrast the specific brain regions and cognitive processes associated with exploitation and exploration decisions. Exploitation activates regions associated with reward seeking, which track and evaluate the value of current choices, while exploration relies on regions associated with attentional control, tracking the value of alternative choices. Second, we propose and test the idea that stronger activation of the brain circuits related to attentional control allows individuals to achieve better decision‐making performance as a result. We discuss the implications of these results for strategic management research and practice. Copyright © 2013 John Wiley & Sons, Ltd 相似文献
