TTH 1100am-1230pm BRB 1.120

show description
A SURVEY OF NEOCLASSICAL AND CONTEMPORARY THEORIES OF THE PRINCIPAL DETERMINANTS OF PRICES AND OF THE ROLE OF PRICES IN ECONOMIC ORGANIZATION. REQUIRED OF STUDENTS MAJORING IN ECONOMICS. STUDENTS MAY NOT ATTEMPT ECONOMICS 420K MORE THAN TWICE.

PREREQUISITE: ECONOMICS 304K AND 304L WITH A GRADE OF AT LEAST C- IN EACH, AND MATHEMATICS 408C AND 408D, OR MATHEMATICS 408K AND 408L, WITH A GRADE OF AT LEAST C- IN EACH.

The primary objective of the course is to study contemporary theories of the principal determinants of prices and the role of prices in economic organization. The course will emphasize the fundamental concepts of microeconomics and provide concrete examples of their application. The course will cover the demand and supply theories for competitive markets, some instances of market power, basics of the game theory, choice under uncertainty, and equilibrium in an exchange and production economy.

TEXTBOOK

Walter Nicholson and Christopher Snyder, Microeconomic Theory: Basic

Principles and Extensions, 10th edition.

TAKE-HOME QUIZES

A take-home quiz will be distributed each Friday and will be collected

at the BEGINNING of class one week later. Each quiz will usually have

three questions. Completed take-home quizes must be submitted on

8.5 x 11.0 inch paper. Late submissions will not be accepted.

(NOTE: if you submit a take-home quiz EARLY, give it directly to the TA).

EXAM DATES and FINAL GRADE

Your final grade will be based on the average quiz score (25%)

and three term exams (25% each).

THE TERM EXAMS WILL BE GIVEN ON:

OCTOBER 1 (Thursday),

NOVEMBER 3 (Tuesday) and

DECEMBER 4 (Thursday).

PLUS/MINUS grades will be assigned for the final grade.

MISSED EXAM POLICY

A missed exam will result in a failing grade, UNLESS acceptable medical

documentation is provided. If a make-up exam is not offered, each of the

other two exams will carry a weight of 37.5% instead of 25%. If a make-up

exam is offered, it may be written or oral. If you are eligible to take

a make-up exam, be prepared to be examined very shortly after the missed

scheduled exam.

WEEKLY RECITATION SESSION

Your TA is Jorge Barro. Each Friday he will review the weekly quiz and

present supplementary material for which you are responsible. Attendance

is MANDATORY. Feel free to contact Mr. Barro during his office hours or

by special appointment. He is devoted to helping you master the material

in this course.

TA email address: jorge.barro@gmail.com

TA Office location: BRB 4.118

TA Office Hours:Wednesday & Thursday, 10:00-11:00 and by appointment.

WARNING

Although class attendance is not used in determining the final grade,

ATTENDANCE IS REQUIRED. I supplement the text material in many ways.

You are responsible for the assigned material in the text AND

for the material presented in class.
