Mathematical Tools for Economists I

Course description:

This course provides an introduction to fundamental mathematic and statistic tools, which are
essential to understand economic theories. It is the first course in a two-course sequence. We
will start with a review of some basic algebraic operations, functions and graphs . Next we
will cover financial mathematics, matrices, and linear programming. Finally a basic
probability theory will be presented.

A scientific calculator is required for this course. Although no particular model is required,
the ones that can handle the calculation of net present value , annuity, and future value will be
quite helpful for this class.


There will be several take-home quizzes, in-class extra credits, three midterm exams, and a
compulsory cumulative final exam. Your course grades will be determined as followings:
Take-home quizzes and in-class extra credits 15 points

Midterm Exam 1 25 points
Midterm Exam 2 25 points
Midterm Exam 3 25 points
Final 35 points

Take-home quizzes are designed to help you learn how to solve mathematical problems and
familiarize yourself with math tools needed to solve them. You are also encouraged to work
on problem sets in the textbook.

There will be absolutely no make-up exams. The Final cannot be replaced with any other
exam under any circumstances. Only two midterm exams will be counted toward your final
grade; the midterm exam with the lowest score will be dropped. Your grade will be
assigned based on the following scale
