Fixes | The New York Times

Fixes explores solutions to major social problems. Each Wednesday, it examines creative initiatives that can tell us about the difference between success and failure. It is written by David Bornstein, author of “How to Change the World,” and founder of dowser.org, and Tina Rosenberg, contributing writer for The New York Times magazine and author of “Join the Club: How Peer Pressure Can Transform the World.” Readers with ideas for future columns can write to the authors at fixes@nytimes.com.
