For principles of macroeconomics courses. An evidence-based approach to economics Macroeconomics presents real economic questions and data to help students learn about the world around them. The text uses themes of optimization, equilibrium, and empiricism to illustrate the power of simple economic ideas and explain and predict what's happening in today's society. In the 3rd Edition, each chapter begins with an empirical question that is relevant to the life of a student. This is later answered using data in the Evidence-Based Economics feature. As a result of the text's practical emphasis, students learn to apply economic principles to guide the decisions they make in their own daily lives.
