 Teaching Tips
You might begin the first class by discussing with the students the role of the intermediate microeconomics
class in the larger curriculum. Encourage the students to be interactive by asking questions, bringing in
examples from the newspaper, and questioning concepts that seem untrue or unrealistic. For many
professors, a primary goal of the course is to get them to think like economists. The material in Chapter 1
should help the students to understand what is required to do so. You might want to ask your students the
policy questions listed below as a kind of pre-test. Simply ask them to write down the best answer they can
for now, and then put their answers away. You can then return to these answers later in the semester.

Some suggested policy questions (be sure to ask only questions that you will address later in the course):

1. How do minimum wages affect wages, employment, and unemployment?

2. Is the CPI a good measure of inflation?

3. Why do stores offer coupons instead of simply reducing the price by the value of the coupon?

4. Why is the price of electricity regulated in most areas?

5. Why do some workers prefer set wages rather than commissions, even if they might make more
working on commission?

6. Agree or disagree: We should strive to be a zero-pollution society.

On a more pragmatic level, I stress to the students that success in the class is heavily dependent on their
approach to the material. Specifically, I emphasize that memorization is an extremely ineffective tool for
studying economics, and that students who memorize material are very prone to confusion and “drawing a
blank” on exams. I try to persuade them that a much better approach is to press for understanding. I also
stress that understanding usually comes only through active engagement with the material, both in class
and out. The problems in the text, as well as the additional problems available in this manual and the Study
Guide, will benefit the students in this regard. The conceptual and technical questions throughout these
problem sets are designed to facilitate student understanding.

I also emphasize the importance of coming to class regularly. Paul Romer’s article, “Do Students Go to
Class? Should They?” in the Journal of Economic Perspectives (vol. 7, no. 3, Summer 1993:167–74)
shows that perfect class attendance is worth between one and two grade points, and attendance at all rather
than half of classes is worth between 0.67 and 1.24 grade points. Referring to this evidence might add
some weight to your argument.

Finally, I recommend that all students bring a protractor and a few colored pencils to class to aid their
note taking. One of the most frequent problems of students who are struggling is sloppy lecture notes. A
protractor is great for drawing lines and curves and has the added benefit of being transparent. Colored
pencils are a big help when students are taking notes on graphs with many different lines, such as income
and substitution effects and long- and short-run cost.

Chapter 1 serves as an introduction to the text as well as a refresher on some basic economic concepts and
definitions. This is a good chapter to get started on during the first day, as most students will not have
read it before class. It will give you the opportunity to get a feeling for the students’ recall of these basic
concepts.

I usually start by asking the class for a definition of economics. If you get several suggestions that do not
include the concept of scarcity, consider writing them on the board. Ask the class if they can think of
what central idea is missing from the definitions given. The discussion of scarcity and the questions of
