This paper presents a model of local network effects in which agents in a social network each value the adoption of a product by a heterogeneous subset of other agents in their quot;neighborhoodquot;, and have incomplete information about the structure and strength of adoption complementarities...

We use data on a real, large-scale social network of 27 million individuals interacting daily, together with the day-by-day adoption of a new mobile service product, to inform, build and analyze data-driven simulations of the effectiveness of seeding (network targeting) strategies under...

It has been conjectured that the peer-based recommendations associated with electronic commerce lead to a redistribution of demand from popular products or "blockbusters" to less popular or "niche" products, and that electronic markets will therefore be characterized by a "long tail" of demand...

This paper presents a model of local network effects in which agents connected by a social network each value the adoption of a product by a heterogeneous subset of other agents in their 'neighborhood', and have incomplete information about the structure and strength of adoption...

We define an economic network as a linked set of entities, where links are created by actual realizations of shared economic outcomes between entities. Such aggregations, which include a wide variety of Web-based product networks, are becoming increasingly available for business use. We analyze...
