In our new edition of Macroeconomics, in addition to updating the existing data and empirical features, we have added Evidence-Based Economics Problems at the end of each chapter. These exercises provide students meaningful practice in analyzing and interpreting real-world economic questions. Here are some examples of other changes in the edition. Throughout this revision, we updated the data and charts to the most recent releases and made the text current for the recent global recession, the COVID-19 pandemic, and the 2020 election. We also undertook a number of more specific changes and added various new materials as we detail next.
