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…
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…
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…
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…
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…
