Flat World Knowledge is honored to publish a new, first edition re-launch of Tim Tregarthen’s wonderful principles of macroeconomics book, and proud to bring Tim's incredible talents as a teacher back to life so future generations of students can continue to learn from him.

In 1996, he published the first edition of his principles of microeconomics textbook to great acclaim, and it became widely used in colleges around the country. That same year, MS made him wheelchair-bound. The disease forced his retirement from teaching at the University of Colorado at Colorado Springs in 1998. He lost the use of his arms in 2001 and has been quadriplegic ever since.

Tim never let his disease get him down. In fact, he turned back to his love of writing and teaching for inspiration. He obtained a voice-activated computer, recruited a co-author, Libby Rittenberg of Colorado College, and turned his attention to revising his principles of economics book.

Today we are excited to introduce Libby Rittenberg and Timothy Tregarthen’s Principles of Macroeconomics. The authors teach economics as the study of ”choice ” by providing students with an accessible, straightforward overview of economics. This textbook combines the clarity and writing of Tregarthen's seminal periodical "The Margin" with great teaching insights.

Rittenberg and Tregarthen help students to understand how real individuals actually work with economics. In this new textbook, the authors illustrate the practicality and relevance of economics with a variety of new illustrations and insights.

The authors take a three-pronged approach to every concept: (1) the concept is covered with a ”Heads Up“ to ward off confusion, (2) a ”You Try It“ section makes sure students are staying on top of the concept and (3) a ”Case and Point“ section that uses a real-world application to harness the concept in reality. For one example of how this plays out in the text see "Chapter 3, Section 2 on Supply".here

This book is intended for a one-semester Principles of Macroeconomics course taught out the social sciences or business school.
