Once a bank run starts, it takes on a logic of its own. Even a solid, solvent bank can't hold up for long if people start to panic. This is a problem for Europe right now, as depositors continue to pull money out of banks in Spain and Greece.
On today's show, we talk to Douglas Diamond, an economist who is one of the go-to guys on bank runs, and we hear from Greek bank teller who is handing out euros to panicked depositors.
We walk through the three things you can do to stop a bank run — and figure out what options are left for Europe.
