Introduction to Macroeconomics:
A Mathematical Approach
This course is one of the two companion courses in introductory economics (the other is

There is one section of this course co-taught by two different professors:
Professor Michael Krashinsky will be teaching the majority of the lectures, which take place on
Mondays and Wednesdays 2:10 p.m. - 3:30 p.m.; Professor Iris Au will be delivering the rest of
the lectures, will be organizing tutorials, will be handling the grades in the course, and will be
holding office hours.
In general, if you want help in the course, the first “line of defense” is the teaching assistants, all
of whom have office hours and are happy to answer questions.
If you feel that you need
additional help, do not hesitate to e-mail either professor, or see Professor Au during her office
Both professors try to respond quickly to e-mail questions (but e-mail is awkward for
complex questions, especially those that involve detailed mathematical notation).
Because of the
size of the class, you are unlikely to get lots of individual time from the professors, especially
right before the exams.
In general, then, you should bring your specific questions about the
material to the t.a.’s, and talk to the professors about more general issues (grades, study
strategies, future course selection, the general state of the economy, etc.).
Professor Michael Krashinsky (we also have a Prof. Harry Krashinsky, so be careful not to get
confused when you try to contact him by phone or e-mail) is the Chair of the Department of

students whenever he is in, and you can always arrange to see him or make an appointment with
his secretary Joy Forbes in the office next door to his, or by speaking to him after or before class.
