What do leaders know?
Giacomo Livan, Matteo Marsili
The ability of a society to make the right decisions on relevant matters relies on its capability to properly aggregate the noisy information spread across the individuals it is ma…
Statistical Mechanics of Competitive Resource Allocation using Agent-based Models
Anirban Chakraborti, Damien Challet, Arnab Chatterjee +3
Demand outstrips available resources in most situations, which gives rise to competition, interaction and learning. In this article, we review a broad spectrum of multi-agent model…
The Social Climbing Game
Marco Bardoscia, Giancarlo De Luca, Giacomo Livan +2
The structure of a society depends, to some extent, on the incentives of the individuals they are composed of. We study a stylized model of this interplay, that suggests that the m…
Phase transitions in crowd dynamics of resource allocation
Asim Ghosh, Daniele De Martino, Arnab Chatterjee +2
We define and study a class of resources allocation processes where agents, by repeatedly visiting resources, try to converge to optimal configuration where each resource…
Collaboration in Social Networks
Luca Dall'Asta, Matteo Marsili, Paolo Pin
The very notion of social network implies that linked individuals interact repeatedly with each other. This allows them not only to learn successful strategies and adapt to them, b…
Threshold learning dynamics in social networks
J. C. González-Avella, V. M. Eguíluz, M. Marsili +2
Social learning is defined as the ability of a population to aggregate information, a process which must crucially depend on the mechanisms of social interaction. Consumers choosin…
Assessing the relevance of node features for network structure
Ginestra Bianconi, Paolo Pin, Matteo Marsili
Networks describe a variety of interacting complex systems in social science, biology and information technology. Usually the nodes of real networks are identified not only by thei…
Congestion phenomena on complex networks
Daniele De Martino, Luca Dall'Asta, Ginestra Bianconi +1
We define a minimal model of traffic flows in complex networks containing the most relevant features of real routing schemes, i.e. a trade--off strategy between topological-based a…
Theory of Rumour Spreading in Complex Social Networks
Maziar Nekovee, Y. Moreno, G. Bianconi +1
We introduce a general stochastic model for the spread of rumours, and derive mean-field equations that describe the dynamics of the model on complex social networks (in particular…
On the role of volatility in the evolution of social networks
Daniele De Martino, Matteo Marsili
We study how the volatility, node- or link-based, affects the evolution of social networks in simple models. The model describes the competition between order -- promoted by the ef…
Collaborate, compete and share
Emanuele Pugliese, Claudio Castellano, Matteo Marsili +1
We introduce and study a model of an interacting population of agents who collaborate in groups which compete for limited resources. Groups are formed by random matching agents and…
Statistical physics of the Schelling model of segregation
Luca Dall'Asta, Claudio Castellano, Matteo Marsili
We investigate the static and dynamic properties of a celebrated model of social segregation, providing a complete explanation of the mechanisms leading to segregation both in one-…
Emergence of time-horizon invariant correlation structure in financial returns by subtraction of the market mode
Christian Borghesi, Matteo Marsili, Salvatore Miccichè
We investigate the emergence of a structure in the correlation matrix of assets' returns as the time-horizon over which returns are computed increases from the minutes to the daily…
Statistical mechanics of socio-economic systems with heterogeneous agents
Andrea De Martino, Matteo Marsili
We review the statistical mechanics approach to the study of the emerging collective behavior of systems of heterogeneous interacting agents. The general framework is presented thr…
Phenomenological Models of Socio-Economic Network Dynamics
George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo
We study a general set of models of social network evolution and dynamics. The models consist of both a dynamics on the network and evolution of the network. Links are formed prefe…
Dynamic instability in a phenomenological model of correlated assets
Giacomo Raffaelli, Matteo Marsili
We show that financial correlations exhibit a non-trivial dynamic behavior. We introduce a simple phenomenological model of a multi-asset financial market, which takes into account…
Critical threshold and dynamics of a general rumor model on complex networks
Maziar Nekovee, Yamir Moreno, Ginestra Bianconi +1
We derive mean-field equations that describe the dynamics of a general model of rumor spreading on complex networks, and use analytical and numerical solutions of these equations t…
Phase coexistence in a forecasting game
Philippe Curty, Matteo Marsili
Individual choices are either based on personal experience or on information provided by peers. The latter case, causes individuals to conform to the majority in their neighborhood…
On the rise and fall of networked societies
George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo
We review recent results on the dynamics of social networks which suggest that the interplay between the network formation process and volatility may lead to the occurrence of disc…
Emergence and resilience of social networks: a general theoretical framework
George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo
We introduce and study a general model of social network formation and evolution based on the concept of preferential link formation between similar nodes and increased similarity…
