The role of administrative costs in policies to improve cooperation
Giacomo Vaccario, Luca Verginer, Frank Schweitzer
We use an agent-based model for studying policies of an abstract government to increase the level of cooperation. In situations where defection is the rational choice, agents recei…
Structurally balanced growing network as randomized Pólya urn process
Krishnadas Mohandas, Piotr J. Górski, Krzysztof Suchecki +3
We investigate a process of growth of a signed network that strictly adheres to Heider structural balance rules, resulting in two opposing, growing factions. New agents make contac…
Adapting to Disruptions: Flexibility as a Pillar of Supply Chain Resilience
Ambra Amico, Luca Verginer, Giona Casiraghi +2
Supply chain disruptions cause shortages of raw material and products. To increase resilience, i.e., the ability to cope with shocks, substituting goods in established supply chain…
Fragmentation from group interactions: A higher-order adaptive voter model
Nikos Papanikolaou, Renaud Lambiotte, Giacomo Vaccario
The adaptive voter model allows for studying the interplay between homophily, the tendency of like-minded individuals to attract each other, and social influence, the tendency for…
Modeling social resilience: Questions, answers, open problems
Frank Schweitzer, Georges Andres, Giona Casiraghi +5
Resilience denotes the capacity of a system to withstand shocks and its ability to recover from them. We develop a framework to quantify the resilience of highly volatile, non-equi…
Reconstructing signed relations from interaction data
Georges Andres, Giona Casiraghi, Giacomo Vaccario +1
Positive and negative relations play an essential role in human behavior and shape the communities we live in. Despite their importance, data about signed relations is rare and com…
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…
Consensus from group interactions: An adaptive voter model on hypergraphs
Nikos Papanikolaou, Giacomo Vaccario, Erik Hormann +2
We study the effect of group interactions on the emergence of consensus in a spin system. Agents with discrete opinions form groups. They can change their opinion based o…
When standard network measures fail to rank journals: A theoretical and empirical analysis
Giacomo Vaccario, Luca Verginer
Journal rankings are widely used and are often based on citation data in combination with a network perspective. We argue that some of these network-based rankings can produce misl…
Should the government reward cooperation? Insights from an agent-based model of wealth redistribution
Frank Schweitzer, Luca Verginer, Giacomo Vaccario
In our multi-agent model agents generate wealth from repeated interactions for which a prisoner's dilemma payoff matrix is assumed. Their gains are taxed by a government at a rate…
What is the Entropy of a Social Organization?
Christian Zingg, Giona Casiraghi, Giacomo Vaccario +1
We quantify a social organization's potentiality, that is its ability to attain different configurations. The organization is represented as a network in which nodes correspond to…
The Mobility Network of Scientists: Analyzing Temporal Correlations in Scientific Careers
Giacomo Vaccario, Luca Verginer, Frank Schweitzer
The mobility of scientists between different universities and countries is important to foster knowledge exchange. At the same time, the potential mobility is restricted by geograp…
Reproducing scientists' mobility: A data-driven model
Giacomo Vaccario, Luca Verginer, Frank Schweitzer
High skill labour is an important factor underpinning the competitive advantage of modern economies. Therefore, attracting and retaining scientists has become a major concern for m…
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 and suppressing ranking bias in a large citation network
Giacomo Vaccario, Matus Medo, Nicolas Wider +1
It is widely recognized that citation counts for papers from different fields cannot be directly compared because different scientific fields adopt different citation practices. Ci…
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…
