Evolutionary economics

I recently discovered a new discipline of economics that I didn't know existed: evolutionary economics. In a nutshell, it tries to understand the economy by drawing parallels with evolutionary theory from biology.

I came across evolutionary economics by accident through an assignment for our microeconomics class. We were asked to find two papers describing non-traditional theories of the firm and compare them. To make the exercise interesting, I tried to find the wildest theory I could find, which led me to The Firm as an Interactor: Firms as Vehicles for Habits and Routines. It's a 2004 paper published by two European economists, Geoffrey Hodgson and Thorbjorn Knudsen, in the Journal of Evolutionary Economics. Yes, there is such a journal (actually, it's the 98th-ranked economics journal, according to Journal-Ranking.com).
