My new economist heros

Hidalgo and Hausmann. The Hidalgo working site is here. If you are an economist, go to that site and look up the working pdfs. When you do you will understand Channel Theory a whole lot better. When they talk about the value of the links, they imply (-log(Vi) * Vi), where Vi is the transaction rate for the  links i, the links handling order i in the minimum redundancy dual network. Better math, better detail, makes better economists.
