This study proposes an exploratory methodology for analyzing participation in Electronic Networks of Practice, focusing on a network of 500 specialists in breast cancer treatment as a case study. The research addresses a critical gap in understanding how conversational dynamics influence...

We document a series of new facts about the very first firms and patents that form new edges in the directed citation networks across patent categories. We call them pathfinder firms and patents. First, the typical pathfinder firms are very larger firms. Second, the average pathfinder patents...

This article aims to clarify how epistemic communities dynamically shape the process of knowledge creation in a localized context and how the evolving interaction between different members of these communities enables knowledge to transit from its locus of emergence to the global market. It is...

Network formation is often said to be driven by social capital considerations. A typical pattern observed in the empirical data on strategic alliances is that of small world networks: dense subgroups of firms interconnected by (few) clique-spanning ties. The typical argument is that there is...

Airplanes were invented by hobbyists and experimenters, and some personal computers were as well. Similarly, many open-source software developers are interested in the software they make, and not focused on profit. Based on these cases, this paper has a model of agents called tinkerers who want...

This paper is concerned with exploring the implications of replicability issues over the medical innovation process. Each research setting is characterized by a specific level of replicability, variability increasing with the complexity of the testing settings. The study introduces new measures...

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with endogenous absorptive capacity. The networks emerge as a result of bilateral cooperation over time between firms occupying different locations in the knowledge space. Social...

While economic factors in directed technical and scientific change have been widely studied, the role of teacher-directed scientific change has received little attention. This paper studies teacher-directed scientific change for one of the largest changes in the direction of research, the...
