How to make health care better through dollars and sense

What is the duty of the government to provide health care to those in need? How to fund it? Should everyone have access to this type of care?

Marketplace’s David Brancaccio recently spoke to one of the book’s co-authors, Amy Finkelstein, co-scientific director of the Abdul Latif Jameel Poverty Action Lab (J-PAL) North America at the Massachusetts Institute of Technology (MIT), where she is an economics professor and a MacArthur Genius Grant winner.
