Given the nature of knowledge and characteristics of the intellectual property rights system, technological transactions tend to be governed by contracts that are costly and not highly profitable. This explains why there are so few technology licensing agreements. However, in some situations, private and specific institutions tend to enable property rights to be more precise, knowledge transfers to be easier, and technology licensing agreements to be less complex to design and to run. This explains why there is a concentration of technology licensing agreements in some industries and in some relational situations. These shed light on the design of firms’ strategies to valorize intellectual assets and of public policies to stimulate innovation and diffusion.  相似文献

Leadership is a matter of both intentions and perceptions, which do not necessarily always match. Because employees’ motivation and commitment are only affected by leadership if they notice it, employee‐perceived leadership is expected to have a stronger correlation with organizational performance than leader‐intended leadership. This expectation is tested for transformational and transactional leadership, as both types of practices are expected to increase performance. Using a sample of 1,621 teachers and 79 Danish high school principals, the authors find that leader‐intended and employee‐perceived transformational and transactional leadership are only weakly correlated and that only employee‐perceived leadership practices (both transformational and transactional) are significantly related to objectively measured school performance. The results show that it is important to distinguish between intended and perceived leadership and that leaders should be aware of how their practices are perceived.  相似文献

Legislators claim that how they explain their votes matters as much as or more than the roll calls themselves. However, few studies have systematically examined legislators’ explanations and citizen attitudes in response to these explanations. We theorize that legislators strategically tailor explanations to constituents in order to compensate for policy choices that are incongruent with constituent preferences, and to reinforce policy choices that are congruent. We conduct a within‐subjects field experiment using U.S. senators as subjects to test this hypothesis. We then conduct a between‐subjects survey experiment of ordinary people to see how they react to the explanatory strategies used by senators in the field experiment. We find that most senators tailor their explanations to their audiences, and that these tailored explanations are effective at currying support—especially among people who disagree with the legislators’ roll‐call positions.  相似文献

We model two aspects of executives in parliamentary democracies: Decision‐making authority is assigned to individuals, and private information is aggregated through communication. When information is relevant to all policies and communication is private, all decisions should be centralized to a single politician. A government that holds cabinet meetings, where information is made available to all decision makers, outperforms one where communication is private: A multimember cabinet can be optimal; it need not be single peaked around the most moderate politician or ideologically connected. Centralization is nonmonotonic in the degree of ideological divergence. In a large cabinet, all power should be given to the most moderate politician. Even when uncertainty is policy specific and a single politician is informed on each policy, power should never be fully decentralized. Our model provides a justification for centralized authority and cabinet meetings that enhance the quality of policy.  相似文献

Online tools such as social media provide new opportunities for citizens and stakeholder groups to be informed, identify common interests, express and share opinions and demands, organize, and coordinate interventions. Therefore, the Internet could be expected to increase stakeholder engagement in corporate affairs and facilitate good governance. In order to provide an overview of current findings on the impact of online media on governance and stakeholder engagement, we conduct a systematic literature review. Our analysis reveals five topical categories of inquiry. We analyze studies from the field of business participation and find a strong bias towards consumer engagement and marketing issues. Only few studies are found to critically explore the effect of online media on power and value distribution between corporations and stakeholders. We then turn to the more established field of political and civic participation in order to further analyze antecedents, forms, and outcomes of online engagement in civic affairs, and derive a framework for future research.

In this article, the aim is to bridge the gap in the international relations (IR) literature on contemporary interventionism between a strand of research mainly focusing on the concepts of intervention, sovereignty and their meanings, and a strand more interested in the particular practices bound up with the phenomenon described as ‘intervention'. This is done by exploring how the literature on the so-called ‘practice-turn' might allow light to be shed on both dimensions. Such an approach might prove fruitful provided attention is paid both to the material and discursive practices of interventionism; both to the transgressive practices constitutive of interventionism and their routinization. Finally, this piece also introduces each of this special section's contributions by showing how they illustrate and expand on the different problématiques here outlined.  相似文献

We present a model of profit diversion into a takeover environment. The model incorporates a legal environment characterized by a probability of being convicted, a monetary sanction (ex-ante protection) and the costs of administrating the takeover (ex-post protection). We show that the extraction of private benefits is reduced by the existence of such a legal environment, which is consistent with a number of empirical studies. It also predicts that legal environment can conduct the bidder to acquire more than 50% of the share due to the impact of the final holding of the bidder on the fine. The paper contributes to the current debate on regulation of white-collar crime. It highlights the trade-off between the ex-post profit diversion and minority protection, and the ex-ante probability of efficient takeovers. But, considering simultaneously two tools of protection, the ex-ante and the ex-post ones, which do not have the same impact, we derive some guidelines in order to analyze the current trend of the US and the EU laws.  相似文献
