Network embeddedness indicates the innovation potential of firms
Giacomo Vaccario, Luca Verginer, Antonios Garas +2
Firms' innovation potential depends on their position in the R&D network. But details on this relation remain unclear because measures to quantify network embeddedness have been co…
Fragile, yet resilient: Adaptive decline in a collaboration network of firms
Frank Schweitzer, Giona Casiraghi, Mario V. Tomasello +1
The dynamics of collaboration networks of firms follow a life-cycle of growth and decline. That does not imply they also become less resilient. Instead, declining collaboration net…
Modeling the formation of R\&D alliances: An agent-based model with empirical validation
Mario V. Tomasello, Rebekka Burkholz, Frank Schweitzer
We develop an agent-based model to reproduce the size distribution of R\&D alliances of firms. Agents are uniformly selected to initiate an alliance and to invite collaboration par…
Data-driven modeling of collaboration networks: A cross-domain analysis
Mario V. Tomasello, Giacomo Vaccario, Frank Schweitzer
We analyze large-scale data sets about collaborations from two different domains: economics, specifically 22.000 R&D alliances between 14.500 firms, and science, specifically 300.0…
Quantifying knowledge exchange in R&D networks: A data-driven model
Giacomo Vaccario, Mario Vincenzo Tomasello, Claudio Juan Tessone +1
We propose a model that reflects two important processes in R&D activities of firms, the formation of R&D alliances and the exchange of knowledge as a result of these collaboration…
A model of dynamic rewiring and knowledge exchange in R&D networks
Mario Vincenzo Tomasello, Claudio Juan Tessone, Frank Schweitzer
This paper investigates the process of knowledge exchange in inter-firm Research and Development (R&D) alliances by means of an agent-based model. Extant research has pointed out t…
The role of endogenous and exogenous mechanisms in the formation of R&D networks
Mario Vincenzo Tomasello, Nicola Perra, Claudio Juan Tessone +2
We develop an agent-based model of strategic link formation in Research and Development (R&D) networks. Empirical evidence has shown that the growth of these networks is driven by…
The role of network embeddedness on the selection of collaboration partners: An agent-based model with empirical validation
Frank Schweitzer, Antonios Garas, Mario V. Tomasello +2
We use a data-driven agent-based model to study the core-periphery structure of two collaboration networks, R&D alliances between firms and co-authorship relations between scientis…
The Rise and Fall of R&D Networks
Mario Vincenzo Tomasello, Mauro Napoletano, Antonios Garas +1
Drawing on a large database of publicly announced R&D alliances, we empirically investigate the evolution of R&D networks and the process of alliance formation in several manufactu…
