On The Glenn Show, Glenn talks to Eldar about his new book, Scarcity: Why Having Too Little Means So Much. Eldar argues that “attention scarcity” sheds light on the behavior of poor parents. Glenn asks Eldar about the politics of poverty, and Eldar cracks a joke about incorrigible economists who feel threatened by his research. Glenn asks Eldar to use his research to explain the Great Recession. Finally, they consider how advertisers profit from attention scarcity—while the public loses.
