Network Structure in Electronic Commerce

I am interested in studying how network structure influence economic outcomes in electronic commerce. In particular, my dissertation seeks to understand how network structure influence demand and demand patterns and whether the structure of the network can be used to improve demand predictions. In trying to answer those questions, my work integrates economic theory as well as methods that originate in social network theory and computer science, into econometric models.
