In this talk we discuss a stochastic model for the spread of demands for products on a graph, which generalizes the contact process, which is a classical model for the spread of disease. We show how the evolution of the demands under this model can be captured by a variant of PageRank called Kronecker PageRank, which captures the interplay between the underlying geometry and the graph and the ‘geometry’ of the demand parameters.
