Today we are excited to introduce Libby Rittenberg and Timothy Tregarthen's Principles of Microeconomics. 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.
