Listen to a podcast here of Libby discussing Principles of Economics to gain perspective on her and Tim's text.



Flat World Knowledge is thrilled to publish a first edition re-launch of Tim Tregarthen’s acclaimed Principles of Economics textbook, and proud to bring Tim's remarkable talents as a teacher to future generations of students.



In 1996, Tim published the first edition of his principles of economics 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 Economics. The authors teach economics as the study of ”choice ” by providing students with an accessible, straightforward overview of economics. This text 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 book, 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 two-semester course in economics taught out of the social sciences or business school.

Timothy Tregarthen University of Colorado at Colorado Springs

There is one word that captures the essence of Dr. Timothy Tregarthen - inspiring. Tim was first diagnosed with MS in 1975. Yet, he continued a remarkable academic career of teaching and research. In 1996, he published the first edition of his principles of economics 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. In 2002, Tim’s doctor expected him to die. He was placed in the Pikes Peak Hospice program, and was twice given his last rites by his priest. UCCS Chancellor Shockley-Zalabak says that “I really thought that Tim would die in Hospice. That’s what the doctors told me, and I really believed that. I remember one day they called me and told me to try to come see him. They didn't expect him to live through the night.” Not only did he live through the night, but eventually recovered to the point that he moved from hospice to a long term care facility. There, he 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. FlatWorld is honored to publish a new, first edition relaunch of this wonderful book, and proud to bring Tim's incredible talents as a teacher back to life for future generations of students to learn from. In addition to completing the re-write of his textbook, Tim recently completed an autobiography about the 32 years he has had multiple sclerosis, titled Suffering, Faith, and Wildflowers. He is nearing completion of a novel, Cool Luck, based on the life of a friend. It is the story of a young couple facing the husband's diagnosis of ALS — Lou Gehrig's disease. Remarkably, in 2007, he was able to return to the classroom at UCCS, where he taught economics for 27 years. Perhaps Tim’s approach to life is best summed up by an observation by UCCS English professor Thomas Naperierkowski: “One of the remarkable things is, heck, I can wake up with a headache and be a pretty grouchy character, but given his physical trials, which he faces every minute of his life these days, I've never seen him grouchy, I’ve never seen him cranky.” Carry on, Tim.
