Paul Romer of Stanford University talks with EconTalk host Russ Roberts about charter cities, Romer's idea for helping the poorest of the poor around the world. Romer envisions a city where the rules about property and safety and contract and so on are rules that allow individuals to flourish in an urban setting in contrast to the cities they live in now where so many aspects of economic and personal life are dysfunctional. Charter cities would be havens for the world's poor and could be created on uninhabited land in either rich or poor countries. This concept raises many difficult practical questions--some of them are discussed here along with how Romer came to be interested in creating the concept and how he hopes to bring it to reality.
