by Kai Ryssdal & Maria Hollenhorst

Here’s a question: How much cash is in your wallet right now? If you answered not a whole lot, that’s not very surprising. It’s getting ever easier to operate in this economy without carrying cash. You tip your Lyft driver on your phone, you pay your dinner bill with a credit card and you Venmo your friends to split the check. Consider then, the future of cash. Bhaskar Charkravorti, the senior associate dean of international business and finance at The Fletcher School at Tufts, has done a number of studies on the subject, including the “Cost of Cash.”  Marketplace host Kai Ryssdal spoke to him about the future of bills and coins in this changing world. The following is an edited transcript of their conversation.
