We develop a model of information exchange through communication and investigate its implications for information aggregation in large societies. An \textit{underlying state} determines payoffs from different actions. Agents decide which others to form a costly \textit{communication link} with,...

We study perfect Bayesian equilibria of a sequential social learning model in which agents in a network learn about an underlying state by observing neighbors' choices. In contrast with prior work, we do not assume that the agents' sets of neighbors are mutually independent. We introduce a new...

The discussion on regional innovation systems emphasizes the duality of local and global links. While the former enable effective knowledge exchange between regional actors, the latter are considered to provide regional systems with knowledge diverse to their knowledge base. Our empirical...

We analyze information and knowledge transfer in a sample of 16 German regional innovation networks with almost 300 firms and research organizations involved. The results indicate that strong ties are more beneficial for the exchange of knowledge and information than weak ties. Moreover, our...

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...

We propose a novel model of knowledge discovery shedding light on the emergence of General Purpose Technologies (GPTs), the process which has been largely neglected in the literature on technological change. We demonstrate that GPTs emerge only when certain conditions with regard to the...

The discussion on regional innovation systems emphasizes the duality of local and global links. While the former enable effective knowledge exchange between regional actors, the latter are considered to provide regional systems with knowledge diverse to their knowledge base. Our empirical...

According to the dominant literature, spatial proximity matters for successful inter-firm collaboration for innovation and more generally for knowledge transfer. This assumption is based on the argument that the tacit character of complex knowledge makes repetitive face-to-face interactions and...

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...
