A Survey In Network Economics: Spam Email, Internet Routing, Graphical Economics, and International Trade

A survey of current topics in network economics, a relatively new and growing field of research at the intersection of economics and network theory. Case studies in spam email, Internet routing, and graphical economics are presented as practical applications. A network economic analysis of international trade is also offered. Most of the current literature addresses a highly technical audience. This paper intends to bridge the gap by presenting network economics in language that will be familiar to students of economics.
