File: Chapter 26 The Keynesian Short-Run Policy Model: Demand-Side Policies
1. In principle, we would expect the aggregate demand curve to be vertical because the price
level is a reference point, the actual value of which should not matter.
2. In the AS/AD model, as the price level falls, the holders of money become richer and buy
more. This is one reason why the aggregate demand curve is downward sloping.
3. The repercussions that the money wealth and international effects have on aggregate
production and aggregate expenditure cause the aggregate demand curve to become steeper than
it would be without such repercussions.
4. The short-run aggregate supply curve is upward sloping in part because increases in aggregate
demand cause some firms to increase their price markups.
5. If productivity and wages both rise by 3 percent, then the aggregate supply curve shifts up.
6. Starting from a long-run equilibrium, an increase in government expenditures increases
output in the short run but not in the long run.
7. If the economy is not in a long-run equilibrium and other things are equal, then prices will
eventually adjust to bring the economy to a long-run equilibrium.
8. Most economists agree that it is possible for fiscal policy to fine tune the economy.
9. As a response to the 2008 recession, the U.S. government employed expansionary policy to
push the economy out to its level of potential output.
10. After the 2008 expansionary policy, unemployment remained higher than desired and output
was much lower than desired.
11. Some economists believe that the good times of the early 2000s were not sustainable because
they were creating a dangerous financial bubble and trade deficit.
12. According to Keynes, the economy could become stuck at a low income level if:
A. declines in aggregate demand and aggregate supply reinforce one another.
B. declines in aggregate demand are not accompanied by declines in aggregate supply.
C. declines in aggregate supply are not accompanied by declines in aggregate demand.
D. aggregate demand and aggregate supply are independent of one another.
13. Equilibrium income is that level of income:
A. which the economy always produces.
B. toward which the economy gravitates in the short-run.
C. which an economy is capable of producing without generating accelerating inflation.
D. which an economy is capable of producing without generating unemployment.
14. Potential income is that level of income that:
A. the economy always produces.
B. toward which the economy gravitates in the short-run.

B. market forces pushing the economy into cumulative spirals were weak.
C. market forces pushing the economy to potential income were weak.
D. market forces pushing the economy to potential income were strong.
17. Keynes believed the economy was:
A. fluctuating around potential income.
B. always at potential income.
C. always moving away from potential income.
D. always moving toward potential income.
18. According to Keynes, market economies:
A. never experience significant declines in aggregate demand.
B. quickly recover after they experience a significant decline in aggregate demand.
C. may recover slowly after they experience a significant decline in aggregate demand.
D. are constantly experiencing a significant declines in aggregate demand.
19. According to Keynes, why might deflation create problems for an economy?
A. Consumers might expect prices to fall further and cut back consumption now
B. In expectation of increased spending, too many entrepreneurs would begin businesses and
most would fail.
C. Producers might increase production to take advantage of falling input prices.
D. People would drop out of unions because unions would become ineffective at keeping wages
of members high.
20. According to the Keynesian model,
A. wages are flexible because workers wouldn't otherwise be able to keep their jobs.
B. the price level is somewhat fixed due to social forces, which keeps an economy from
remaining at an equilibrium level of unemployment.
C. prices are subject to significant fluctuations as demand and supply change.
D. the government puts price controls on the economy, keeping the price level fixed.
21. From 2007 to 2012, the U.S. personal savings rate rose. If the additional savings were not
translated into investment, Keynes would predict that aggregate income would:
A. decline and remain there.
B. rise indefinitely.
C. accelerate.
D. rise and remain there.
22. The paradox of thrift occurs when:
A. an increase in saving raises output.
B. an increase in saving reduces output.
C. saving is unrelated to output.
D. a decrease in saving reduces output.
23. Keynes believed that an increase in savings would:
A. raise aggregate demand by reducing investment.
B. raise aggregate demand by increasing consumption
C. reduce aggregate demand by reducing investment.
D. reduce aggregate demand by reducing consumption.
24. The paradox of thrift will not arise if:

A. principle of substitution.
B. principle of opportunity cost.

D. relationship between the price level and total output.
28. The AS/AD model looks similar to the microeconomic supply and demand model
A. but is not based on it.
B. is based on the microeconomic supply and demand model because the AS/AD is a macro
representation of the micro model.
C. is based on the microeconomic supply and demand model because both are based on the
principle of substitution.
D. is based on the microeconomic supply and demand model because both are based on
opportunity costs.
29. The reason why the AS/AD model does not depend upon the concepts of substitution and
opportunity cost is that:
