Principles of Macroeconomics, v. 2.1


Libby Rittenberg & Timothy Tregarthen



      Chapters thoroughly incorporate the recent recession and recovery— placing it in historical and theoretical context, including the controversies surrounding how the government responded to it.


Updated chapters cover relevant topics such as the history of hyperinflations, assessing growth prospects in different countries, controversy on how to manage the increase in U.S. government debt, and trade issues during the Great Recession.

Libby Rittenberg and Timothy Tregarthen’s goals in writing Principles of Macroeconomics, v. 2.1 were simple:

  • Provide an accessible, straightforward, and clearly written overview of macroeconomics


      • “HEADS UP”:

Each concept is covered with a ”Heads Up“section to clarify potentially confusing aspects.

      • ”YOU TRY IT”:

This section encourages students to walk through scenarios related to each concept and idea.

      • ”CASE IN POINT”:

This section uses a real-world applications to harness concepts in reality.


Additionally, the Flat World Knowledge publishing model allows instructors to adapt the textbook to the exact needs of their specific class and student body.
