The research of Arindrajit Dube is referenced in a story about whether London should adopt its own minimum wage. Dube gave a talk at the Resolution Foundation recently where he discussed his work on how localities in the U.S. set the minimum wage based on local conditions. Dube also contends that raising the minimum wage has a small impact on employment and encourages workers to stay in their jobs.
