The second (2020) edition of this textbook, originally published 2008 by Cambridge University Press, is freely available. "This book is different from the many other books that attempt to teach microeconomics in three ways:
- It explicitly applies the recipe of the economic approach in every example.
- It uses concrete examples via Microsoft Excel in every application, which enables the reader to manipulate live graphs and learn numerical methods of optimization.
- The majority of the content is in the Excel workbooks which the reader uses to create meaning."
