Chapter 02 – The Market System and the Circular Flow
students to “treat the bikes as if they were your own property.” Evidently, her column spurred
little change.
On April 21, SGA President M. Lynsey Morris e-mailed all students that “It has come to
our attention here in the SGA office that many students are failing to take care of the Berry
Bikes…. These bicycles are top quality and should not be bending and breaking the way they are.
The [SGA] officers and other students have seen many people riding the bikes at absurd speeds,
doing tricks, and just abusing the bicycles in general.” She too requested that students “treat [the
bikes] as you would your personal property.” Morris’s appeal [also] apparently met with little
success; a survey at the end of the semester revealed that four of the 20 bikes were lost or stolen
and 11 were in a state of disrepair.
Undeterred, the SGA had the bicycles repaired over the summer recess and resumed the program in the
fall. It soon became apparent that the abuse would continue. The September 10 Campus Carrier
editorialized about “mangled corpses of twisted red metal that lie about campus” and concluded that
“Perhaps SGA put too much trust in human nature and Berry students’ respect for property.” Was that the
problem? Or was it that the SGA did not understand the role of incentives? Only a month into the new
semester, the SGA suspended the program with the intention of leasing the remaining bicycles to students
on a semester–by-semester basis, thereby alleviating the problems associated with common-property
resources.
3. If you haven’t already talked about Adam Smith and his role in economics, this may be a good time
to introduce the “father of economics.” His emphasis on the role of self-interest in motivating
economic activity is especially relevant here. You might place copies of the “Wealth of Nations”
on reserve at the library to encourage students to sample the original work. You could use short
excerpts as the basis for discussion or essays. “Adam Smith and the Wealth of Nations,” a 28-
minute video/film, is an excellent supplement. Check with your Federal Reserve District Bank’s
public information office or your nearest Center for Economic Education for availability.
4. Markets coordinate economic activity and changes in prices (products and resources) signal that
changes have occurred within particular markets. A simple example of product X and product Y
can be used. Assume an increase in the demand for X. This change will lead to an increase in the
price of X, an increase in the profitability of X, an increase in the quantity supplied of X, an
increase in the demand for the resources used to produce X, and an increase in the prices of the
those resources. Because of a limit in consumer income, the demand for Y is assumed to decrease
followed by all of the changes that will occur in response to the decrease in the demand of Y. After
all of these changes have occurred, explain how the transferable resources will move from Y to X.
This illustrates the concepts of the “invisible hand.”
5. This is a good time to reintroduce the concept of goods for the future from chapter 1. In discussing
the importance of producing goods for the future for the market system, remind the students of the
impact upon the production of consumption goods in the present.
6. In discussing the use of money, the following Concept Illustration may be useful.
Imagine a worker producing alternators for automobiles. At the end of the week, instead of
receiving a piece of paper signed by the company, or a few pieces of paper engraved in green and
black, the worker’s pay consists of ten alternators. With no desire to hoard alternators, the
worker ventures into the business district to spend this income on groceries, clothing, and a
movie. Obviously, the worker is faced with some inconvenient and time-consuming trading, and
may not be able to negotiate any exchanges at all. Finding an owner of a clothing store who
needs an alternator can be a formidable task. And if the clothing does not trade evenly for the
alternators, how do the parties “make change”?
