Microeconomic Theory:
Basic Principles and Extensions
12th Edition
Solutions Manual
Walter Nicholson & Christopher
Snyder
Preface
This Solutions Manual for the 12th edition of Microeconomic Theory: Basic Principles and
Extensions provides answers to all of the end-of-chapter problems, and the answers are provided
in more detail than the Brief Answers in the back of the textbook. It also includes a brief
introductory statement about the nature of the problems in each chapter and brief notes on the
economic point of each problem. This additional descriptive material may help to focus
discussions about the problems and serve to integrate them more completely with the theoretical
material in the text. That is especially important for problems that incorporate theoretical
concepts which, while not sufficiently central to warrant explicit treatment in the text, contain
ideas that should be understood by most students of economic theory.
Problems that introduce such basic results are explicitly highlighted in the commentary.
In general, the problems in the text are arranged from the least to most difficult. Particularly
difficult problems are separately identified here together with some hints on how to get students
started on them. All of the text is set using Word 2010 and most of the in-line and displayed
math is typeset using Math Type 6.7.
For the end-of-chapter problems we have assigned in our own classes, we have found
several methods of cutting and pasting from this manual into a problem set answer key for the
class to be particularly convenient. One way is simply to copy the answer to the relevant
problem from the Word files provided into a new Word file for the class answer key. Another is
to use the “snapshot tool” in Adobe Acrobat Professional to select and copy the relevant block
from the PDF files provided into a PowerPoint or other file format containing the class answers.
Blowing the PDF file up to around 200% before applying the snapshot tool helps maintain a
readable resolution.
The authors are grateful to Henry Senkfor and Paulina Karpis, undergraduate students at
Dartmouth College, for their extensive work on various editions of this manual. We are indebted
to Kory Hirak for administrative assistance, Joseph Malcolm and his colleagues at Lumina
Datamatics for excellent copyediting and production management, and Anita Verma for content
development. Christopher Snyder thanks his wife, Maura Doyle, for numerous suggestions
compiled from her use of the book in her intermediate micro classes at Dartmouth. Walter
Nicholson thanks the many generations of Amherst College students who have sometimes
struggled through these problems, often offering good advice on how to improve them.
Every attempt has been made to purge the errors remaining from previous editions, but
errors and confusing passages may remain. The solutions to the problems new in this edition
will invariably contain some new errors as well. We encourage instructors to email us
(chris.snyder@dartmouth.edu) with comments and corrections. We are grateful to these
instructors, a number of whom are thanked by name in text’s preface, for their help in continually
improving the quality of the book.
