What Is Money

4 sessions, in order

Four sessions tracing money from an invented trust system to invented psychology. First, why coins and paper only work because everyone agrees they will, from barter through digital. Then, how a price actually gets set at auction, and why the same idea explains both bubbles and inflation. Then two more: the tricks a price tag itself plays on you, a deliberately bad option that makes another one look smart, and a $9.99 that reads nowhere near $10. Money turns out to be part invention, part psychology, the whole way down.
