A Term
This course is divided into three sections. The first deals with the theories of consumer behavior
and demand. The second treats theories of production, cost, supply, and the firm under various
types of market structure, including perfect competition, monopoly, and structures intermediate
between these two extremes. The third part of the course focuses on factor markets and general
equilibrium (as distinct from partial equilibrium, which is an implicit assumption in most of the
earlier material of the course), as well as externalities, property rights, and the Coase Theorem.)
EXAMINATION SCHEDULE/GRADING POLICY
Two major examinations worth 100 points each will be given, with the exception noted below.
The first will be on Monday, June 20, and will treat all material covered through Friday, June
17. The second will be on Thursday, July 7, and will cover only the second part of the course.
Each exam will be worth 100 points. In addition to these exams, a quiz will be given on
Tuesday, June 14. This quiz, worth 20 points, will cover all material treated through June 13.
The idea behind the quiz is to offer the student an opportunity to experience the type of
examination given on the two exams noted above. The results of the quiz will be treated like
a bonus in that the points will be added into the student's score after the grade distribution
(based on 200 points) is determined from the two major exams.
Before the quiz and each examination, I will conduct a review session.
NOTE: No makeup exams are offered and none will be scheduled.
