argument unfolds rather than by relying on the finished diagram as it
appears in the book.
The end-of-chapter Study Exercises require you to practise using some of
the concepts that you learned in the chapter. These will be excellent
preparation for your exams. To provide you with immediate feedback, we
have posted Solutions to Selected Study Exercises on MyLab Economics
(www.pearson.com/mylab). We strongly advise that you should seek to
understand economics, not to memorize it.
The red numbers in square brackets in the text refer to a series of
mathematical notes that are found starting on page M-1 at the end of the
book. For those of you who like mathematics or prefer mathematical
argument to verbal or geometric exposition, these may prove useful.
Others may disregard them.
In this edition of the book, we have incorporated many elements to help
you review material and prepare for examinations.
We encourage you to make use of MyLab Economics that accompanies
this book (www.pearson.com/mylab) at the outset of your studies.
MyLab Economics contains a wealth of valuable resources to help you.
MyLab Economics provides Solutions to Selected Study Exercises. It also
includes many additional practice questions, some of which are modelled
on Study Exercises in the book. You can also find an electronic version of
the textbook.
