Title : Information and Decisions in Social Networks
Download the presentation - 4.81 MB
Social networks often have a profound impact on our economic outcomes. I will cover some elementary network theory and then look at several ways of using social network data for economic analysis. I will explain how simple dynamic network formation processes can lead to rich and complex networks. Then I will show how to estimate behavioural parameters in linear social interaction models in static networks. Finally, I will discuss how to identify "key players" and how to deal with estimation when social networks are endogenous.
