Many people think of the economy as following a set of fairly scientific principles.
We buy more if things are cheap. We buy less if they're expensive. Companies hire more people if it looks like the economy is growing. They cut back if it looks like things are going to tank. Or say you're in charge of the Federal Reserve. Economic indicators help decide whether to raise or lower interest rates.
All of this seems very rational, very mathematical.
But Nobel Prize winner and economist Robert Shiller suggests that this kind of thinking might be too narrow.
This week on Hidden Brain, we talk with Shiller about the role stories play in our economic lives — not just the purchases we make as individuals, but the fate of entire economic systems.
Then, we go further back in time to examine a story about what the world look like before money was invented. It's a story built on the idea of barter.
"It goes something like this: in the beginning, before there was money, if I had something that you needed, I would approach you with that thing and see if you had anything that I needed," says anthropologist Bill Maurer.
"The problem is that when we look around the world and in the historical and archaeological record for instances of this kind of direct barter, unfortunately we don't find it."
Maurer challenges established ideas about the origins of currency, and highlights the connection between money and relationships.
"Society is a thing of ongoing continuous relationships. The settling and unsettling of debts, on and on and on and on and on."

You won’t find a paywall here. Come as often as you like — we’re not counting. You’ve found a like-minded tribe that cherishes what a free press stands for. If you can spend another couple of minutes making a pledge of as little as $5, you’ll feel like a superhero defending democracy for less than the cost of a month of Netflix.
