First of all, I must admit that my major isn't related to economics, so I had little previous knowledge of economics when I began reading the book. I was simply looking for an introduction to microeconomics and sort of randomly bumped into this book. I found that the authors' exposition of various topics is not very clear and the explanations are sometimes lacking sufficient detail. More importantly, the order of presentation needs improvement; quite often I found myself going back and forth in the pages of the book, trying to understand what the authors want to say. If you are looking for an introductory textbook in microeconomics, you can probably find something much better (I might suggest one of Varian's books, depending on your mathematical background; I found "Intermediate
Microeconomics" quite good).
