Optimal promotions of new products on networks

Gadi Fibich, Amit Golan

We present a novel methodology for analyzing the optimal promotion in the Bass model for the spreading of new products on networks. For general networks with nodes, the optimal…

Funnel theorems for spreading on networks

Gadi Fibich, Tomer Levin, Steven Schochet

We derive novel analytic tools for the Bass and SI models on networks for the spreading of innovations and epidemics on networks. We prove that the correlation between the nonadopt…

Monotone convergence of spreading processes on networks

Gadi Fibich, Amit Golan, Steven Schochet

We analyze the Bass and SI models for the spreading of innovations and epidemics, respectively, on homogeneous complete networks, circular networks, and heterogeneous complete netw…

Boundary Effects in the Diffusion of New Products on Cartesian Networks

Gadi Fibich, Tomer Levin, Kenneth Gillingham

We analyze the effect of boundaries in the discrete Bass model on D-dimensional Cartesian networks. In 2D, this model describes the diffusion of new products that spread primarily…

Universal Bounds for Spreading on Networks

Gadi Fibich, Tomer Levin

Spreading (diffusion) of innovations is a stochastic process on social networks. When the key driving mechanism is peer effects (word of mouth), the rate at which the aggregate ado…

Compartmental limit of discrete Bass models on networks

Gadi Fibich, Amit Golan, Steve Schochet

We introduce a new method for proving the convergence and the rate of convergence of discrete Bass models on various networks to their respective compartmental Bass models, as the…
