Intermediate microeconomics (EC111)

Brown University, Spring 2000

General description

The course intermediate microeconomics discusses first the theories of consumer and firm decision making. Then we turn to study how prices are determined in equilibrium and how resources are allocated. We will consider both competitive markets and markets with a monopolist. We will also study concepts of economic efficiency and evaluate whether different markets mechanisms result in an efficient allocation of resources.


The prerequisites are: MA6, MA7, MA9 or equivalent; and EC11 or advanced placement. Willingness to work hard is strongly recommended.


Lectures are scheduled for Monday, Wednesday and Friday, 10:00-10:50. The professor may be contacted in several ways. The teaching assistant is Mr. Min, and his conference sections are in Thursday 12:00 and 7:00.


The grades will be composed of the following parts: Homeworks 10%, midterm exam 35% and final exam 55%.

The midterm exam is scheduled for March 8th, 2000.
