#362: Should Iceland Kill The Krona?

Iceland has about as many people as Staten Island. It also has its own currency, the krona. This raises a question: Does it make sense to have a currency that's only used by 300,000 people?After the country's economy blew up in the financial crisis, the government put the krona on lock down. Now, they're trying to decide whether to stay with the krona, or abandon it, and use someone else's currency.Today's show features special guest host Baldur Hedinsson, a former Planet Money intern who recently moved back to Iceland. We also hear from his sister, who is working in a town where people walk around with rifles to ward off polar bears. And we talk to Robert Mundell, who won a Nobel for working on questions like the one Iceland is facing.
