Understanding Our Economy concentrates on principles, people, and events. The principles side of economics provides the tools we need to understand the past and the present and to plan for the future. The people part shows us that we are never entirely predictable and that we frequently do very special things. For this reason, economics is both a science and an art that involves more than what economists say and do. It is a discipline that relates to all of us through the policies we support, the votes we cast, and the careers we choose.
