FDL’S BOOK SALON: When Mandates Work: Raising Labor Standards at the Local Level. “Starting in the 1990s, San Francisco launched a series of bold but relatively unknown public policy experiments to improve wages and benefits for thousands of local workers. Since then, scholars have documented the effects of those policies on compensation, productivity, job creation, and health coverage. Opponents predicted a range of negative impacts, but the evidence tells a decidedly different tale. This book brings together that evidence for the first time, reviews it as a whole, and considers its lessons for local, state, and federal policymakers.” Chat with Ken Jacobs, Michael Reich, and Miranda Dietz about their new book. Hosted by Erik Loomis. 5pm ET, 2pm PT Sunday.
