A Minimal Dynamical Model for Incubation-Outbreak Transitions in Social Norm Diffusion
Run Wang, Leonardo Cianfanelli, Giacomo Como +1
In this paper, we introduce a minimal dynamical model for the diffusion of a new social norm, in which individuals transition among three states: non-supporters, silent supporters,…
Bayesian Equilibria of Heterogeneous Non-Atomic Routing Games with Private Information
Alexia Ambrogio, Leonardo Cianfanelli, Giacomo Como +1
We study non-atomic Bayesian routing games whereby a transportation network is shared by two types of traffic: a coordinated fleet and a mass of selfish users. The links in the net…
Optimal Interventions on the Linear Threshold Model in Large-Scale Networks
Leonardo Cianfanelli, Sebastiano Messina, Giacomo Como +1
We study an optimal intervention problem on the linear threshold model (LTM) in which a social planner aims to design minimal-cost interventions that modify the agents' thresholds,…
Optimal Control of Behavioral-Feedback SIR Epidemic Model
Martina Alutto, Leonardo Cianfanelli, Giacomo Como +2
We consider a behavioral-feedback SIR epidemic model, in which the infection rate depends in feedback on the fractions of susceptible and infected agents. Contrary to the classic S…
Behavioral-feedback SIR epidemic model: analysis and control
Martina Alutto, Leonardo Cianfanelli, Giacomo Como +2
This paper investigates a behavioral-feedback SIR model in which the infection rate adapts dynamically based on the fractions of susceptible and infected individuals. We introduce…
On Optimality of Private Information in Bayesian Routing Games
Alexia Ambrogio, Leonardo Cianfanelli, Giacomo Como
We study an information design problem in transportation networks, in the presence of a random state that affects the travel times on the links. An omniscient system planner -- aim…
Optimal interventions in opinion dynamics on large-scale, time-varying, random networks
Leonardo Cianfanelli, Giacomo Como, Fabio Fagnani +2
We consider two optimization problems in which a planner aims to influence the average transient opinion in the Friedkin-Johnsen dynamics on a network by intervening on the agents'…
Network Behavioral-Feedback SIR Epidemic Model
Martina Alutto, Leonardo Cianfanelli, Giacomo Como +1
We propose a network behavioral-feedback Susceptible-Infected-Recovered (SIR) epidemic model in which the interaction matrix describing the infection rates across subpopulations de…
On the dynamic behavior of the network SIR epidemic model
Martina Alutto, Leonardo Cianfanelli, Giacomo Como +1
We study a susceptible-infected-recovered (SIR) epidemic model on a network of interacting subpopulations. We analyze the transient and asymptotic behavior of the infection dyn…
Information design in Bayesian routing games
Leonardo Cianfanelli, Alexia Ambrogio, Giacomo Como
We study optimal information provision in transportation networks when users are strategic and the network state is uncertain. An omniscient planner observes the network state and…
On the stability of the logit dynamics in population games
Leonardo Cianfanelli, Giacomo Como
We study the asymptotic stability of the logit evolutionary dynamics in population games, possibly with multiple heterogenous populations. For general population games, we prove th…
Stability and bifurcations in transportation networks with heterogeneous users
Leonardo Cianfanelli, Giacomo Como, Tommaso Toso
A critical aspect in strategic modeling of transportation systems is user heterogeneity. In many real-world scenarios, e.g., when tolls are charged and drivers have different trade…
Lockdown interventions in SIR model: Is the reproduction number the right control variable?
Leonardo Cianfanelli, Francesca Parise, Daron Acemoglu +2
The recent COVID-19 pandemic highlighted the need of non-pharmaceutical interventions in the first stages of a pandemic. Among these, lockdown policies proved unavoidable yet extre…
Optimal intervention in transportation networks
Leonardo Cianfanelli, Giacomo Como, Asuman Ozdaglar +1
We study a network design problem (NDP) where the planner aims at selecting the optimal single-link intervention on a transportation network to minimize the travel time under Wardr…
On stability of users equilibria in heterogeneous routing games
Leonardo Cianfanelli, Giacomo Como
The asymptotic behaviour of deterministic logit dynamics in heterogeneous routing games is analyzed. It is proved that in directed multigraphs with parallel routes, and in series c…
