We all know that air pollution is bad for our health. But what is often overlooked is that high pollution levels also cause significant harm to our economic well being. Brian Viard, Associate Professor of Strategy and Economics at CKGSB, has been researching the economic effects of pollution for much of the past few years. His team has found persuasive evidence that the costs of air pollution are greater and more wide-ranging than most people realize. In this interview with CKGSB Knowledge, he explains how tackling the pollution crisis could actually make the Chinese economy more productive.
