Mike Munger of Duke University talks with EconTalk host Russ Roberts about the sharing economy--companies like Uber, AirBnB, FlightApp, and DogVacay that let people share their houses, cars, or other assets with strangers in exchange for money. These companies dramatically increase the use of resources that would otherwise be idle and disrupt existing services such as hotels and taxis. Topics discussed include the regulatory response to these companies, the politics of that response, and the significance of these new products. The conversation closes with the potential impact of Uber combining with driverless cars to change the automobile industry and cities.
