Patent data have been widely used in research to characterize firms' locations in technological or knowledge space, as well as the proximities among firms. Researchers have measured firms' technological or knowledge proximities with a variety of measures based on patent data, including Euclidean...

Patent data have been widely used in research on technological innovation to characterize firms' locations as well as the proximities among firms in knowledge space. Researchers could measure proximity among firms with a variety of measures based on patent class data, including Euclidean...

A large body of literature has explored the challenges of technological change for established firms. Much of this work has focused on factors internal to firms, such as inertial routines or managers' cognitive limitations that constrain incumbents' development of new capabilities and response...

This article empirically explores the relations between alternative organizational designs and a firm's ability to explore as well as exploit. We operationalize exploitation and exploration in terms of innovation streams; incremental innovation in existing products as well as architectural...

This longitudinal study examines the impacts of supervisors' promotion paths and gatekeeper status on the career outcomes of technical subordinates in a dual ladder system. Results indicate that project supervisors significantly affect the chances of one's promotion along each track....

How do organizations survive in the face of change? Underlying this question is a rich debate about whether organizations can adapt--and if so how. One perspective, organizational ecology, presents evidence suggesting that most organizations are largely inert and ultimately fail. A second...

This research explores the performance consequences of CEO succession, executive team change, and strategic reorientation in different contexts. Based on team demography and organization learning ideas, we argue that CEO succession or executive team change enhances incremental organization...

This paper develops a research design for examining the relative influence of managers and environments on organizational activity over time. We outline three basic models of organization evolution: (1) an inertial model, which emphasizes constraints on evolution imposed by early patterns of...

We take a structural approach to assessing innovation. We develop a comprehensive set of measures to assess an innovation's locus, type, and characteristics. We find that the concepts of competence destroying and competence enhancing are composed of two distinct constructs that, although...
