March 11 (Bloomberg) -- A highly unusual collaboration
between economists and scientists offers an important insight
for those who want to fix the world’s crisis-prone financial
system: There’s no simple way to understand a complex network.
This month’s issue of the research journal Nature Physics
features a handful of papers in which physicists, other natural
scientists and leading experts in economics and finance --
including prominent banking regulators and Nobel Prize-winning
economist Joseph Stiglitz -- put their minds together to figure
out finance. What the scientists bring to the table is
experience in studying networks, bewildering tangles of
interlinked and interdependent things such as an ecological food
web or the Internet.
