Introduction
About This Course
Course Description
In this course, we study contemporary microeconomic theory. We study
theories of consumer and producer behavior; the role of markets in coordinating
economic activity; market structures and market imperfections; the conditions
under which markets can be depended on to allocate resources efficiently; and
how government policies, e.g. taxes, alter market outcomes. The course is
designed to give you the economic tools for the applied economics courses that
follow it.
Course Organization
The course consists of seventeen lessons grouped into eight units of study.
Each lesson has a W HAT YOU SHOULD K NOW component that lists questions you
should be able to answer, and concepts, terms and relationships you should
understand. It also includes a READING ASSIGNMENT drawn from the required
textbook, and often a graded, WRITTEN ASSIGNMENT to be submitted via
MyEconLab.
As part of your study for each lesson, you should login to
http://www.coursecompass.com/ and go to your course: Microeconomic Theory.
There you will find a list of assignments and due dates. Details about accessing
CourseCompass are provided on the ICON course site. Each graded assignment
will be listed as Quizzes and Tests . You will also be able to access a number of
study aids, listed below:
Study Plan , where you can work through exercises for each chapter.After you think you understand the content of a lesson, you should
take the sample test. If you do not do well on this sample test, review
again the reading and multimedia materials.

Textbook Resources , where you will find additional study aids and
supplemental materials, including Lecture Notes, Practice Quizzes,
Solved Problems, and Applications . To reinforce what you have read,
you should view animations and slide shows in the multimedia
library .
Economic news , where you can apply what you have learned in each
lesson to real world situations reported in the New York Times,
eThemes of the Times .
Student Center , where you can go to the tutor center for one-on-one
help.
Results , which gives you an up-to-date record of your scores on eachtest or quiz you have taken.
If you have questions about an assignment, send a detailed question to the
instructor by e-mail. Please be as specific as you can, as it is not possible for your
instructor to provide a helpful response to unfocused general questions. You need
to make every effort to understand the problem yourself, using the course
materials available to you, before asking the instructor for assistance.
Deadlines for submitting assignments and taking exams are noted in the
course syllabus. Practice assignments are available in CourseCompass. You
should complete the practice assignment prior to completing the graded
assignment.
Examinations
There are two supervised examinations, a 90 minute midcourse exam and
a two-hour final (comprehensive). Each exam consists of multiple-choice
questions (50 for the midterm and 75 for the final exam) that are similar to thequestions in the graded assignments. Books, notes, and computers cannot be
referred to during these exams. A standard non-programmable calculator is
allowed.
