b. right by $200 billion.
c. right by $400 billion.
d. left by $400 billion.

a. decrease in the price of one product will cause an increase in the demand for the
other product.
b. decrease in the price of one product will cause a decrease in the demand for the other
product.
c. increase in the price of one product will cause an increase in the supply of the other
product.
d. increase in the price of one product will cause a decrease in the supply of the other

Which of the following characterizes the IACs?
a. High per capita GDP growth and high population growth.
b. Low per capita GDP growth and low population growth.

Monetarists believe:
a. the cause-and-effect relationship hypothesized by the Keynesians understates the
impact of stimulative monetary policy.
b. the cause-and-effect relationship hypothesized by the Keynesians is an accurate
description of how monetary policy works.
c. since the economy is operating at full employment, any stimulative monetary policy
will cause the inflation rate to rise.
d. the cause-and-effect relationship hypothesized by the Keynesians is backwards, and
decreases in the money supply actually stimulate economic activity.
e. the cause-and-effect relationship hypothesized by Keynesians will not work because
investment does not respond to changes in interest rates.
Just before class, Jim tells Stuart, "Stuart, you shouldn't skip class today because you
have paid tuition to enroll in the class." Stuart ignores Jim's advice, and instead makes
the decision of whether to attend based on the importance to his grade that he feels he'd
be missing that day in class relative to his value of the extra time he could have to finish
the video game he is playing. To an economist, Stuart is:
a. using marginal analysis.
b. ignoring the total value of attending class.
c. ignoring the concept of opportunity cost.
d. irresponsible.

The curve that shows the relationship between the price of a good and the quantity that
consumers are willing to purchase at each price is the
a. supply curve.
b. demand curve.
c. production possibilities curve.
d. consumption curve.
Sam is a musician who is out of work because electronic equipment replaced live
musicians. This is an example of:
a. frictional unemployment.

The aggregate supply curve reflects the relationship between the price:
a. of a particular good and the quantity supplied by all firms producing that good.
b. of a particular good and the quantity supplied by the aggregate economy.
c. level and the quantity supplied of all goods in the economy.
d. level and the quantity of all goods purchased in the economy.

John Maynard Keynes listed three types of motives for people holding
money-transactions, precautionary, and speculative.
If the marginal propensity to consume is 0.80, the value of the spending multiplier will
be 4.
The size of the spending multiplier depends on the marginal propensity to consume
(MPC).

Borrowing from foreign banks by U.S. firms represents a capital inflow.
The entire national debt is owed to U.S. citizens.
Following Keynesian economics, and assuming a marginal propensity to consume
(MPC) of 0.75, an increase in federal government spending of $100 billion at below full
employment would be expected to shift the aggregate demand curve by $300 billion to
the right.
In the United States, the unemployment rate for blacks is roughly the same as the
unemployment rate for whites.
What is an economic theory or model? What constitutes a "good" economic theory or
model?
