Economic theory is great, but often needs adjustments for human unpredictability... like our altruistic or emotional reasons for doing things.
Ergodicity is a way of rethinking economic theory. Instead of plotting many possible futures from today, and picking the best one, Ergodicity looks at making decisions in a serial fashion, over time, to better model human economic behavior and influences.
This article is clearly written for someone with my less-than-informed economic skills and knowledge. But it links to the source materials that I expect several people here on Hubski have have distinct FEELINGS about.
I look forward to reading those analyses...
(NOTE: Please excuse the author for their subterfuge in the first paragraph. They are trying to make economics interesting to the layman, and it's a cheap stunt, but it worked on me. I read the whole thing.)
