At times knowledge can be seen as the source of organizational innovation and change-at other times, however, it can be the very constraint on that change. This conflicted role offers insights into why the phenomenon of organizational knowledge has been interpreted by researchers in multiple and possibly conflicting ways. Some theories depict knowledge as an empirical phenomenon, residing in action and becoming "organizational" in the acquisition. diffusion, and replication of those actions throughout the organization. Others consider it a latent phenomenon, residing in the possibility for constructing novel organizational actions. This paper argues that while each of these qualities-empirical and latent-are intrinsic to knowledge in organizations. our understanding of organizational phenomena is essentially incomplete until the relationship between them is considered. Building on structuration theory. we propose a complementary perspective that views organizational knowledge as the product of an ongoing and recursive interaction between empirical and latent knowledge. between knowledge as action and knowledge as possibility. We ground this complementary model of knowledge in evidence from the field study of two firms whose innovation practices provide unique insights into how knowledge simultaneously enables and constrains behavior in organizations. We then discuss how a complementary perspective avoids the reification of knowledge by depicting it instead as an ongoing and social process and offers an alternative distinction between individual and collective knowledge

Our study addresses two main questions: First, what types of alliances do firms tend to create when combining different kinds of resources? Second, what governance mechanisms do firms set up to coordinate and protect resources when they use them for different alliances? We examine 227 alliances between competitors in Asia, North America, and Europe. We first identify two types of alliances: scale alliances in which the partner firms contribute similar resources, and link alliances in which the partners contribute complementary resources. We find that firms contributing R&D and production resources tend to form scale alliances, while firms contributing marketing resources tend to enter into link alliances. We also find that firms are more likely to choose stronger protection mechanisms for link alliances, which create greater appropriation risks, while they tend to seek higher levels of coordination in scale alliances

As of 1987, commercial banks in the United States were allowed to establish Section 20 subsidiaries to conduct investment-banking activities. A concern of regulators was that these activities would result in a decrease in performance of commercial banks relative to the risk being undertaken. This paper examines the performance of commercial banks around the establishment of a Section 20 subsidiary. We find that Section 20 activities undertaken by banks result in increased industry-adjusted operating cash flow return on assets, due mainly to revenues from noncommercial-banking activities. Further, risk measures for the sample banks do not change significantly.
