Chapter 1. The Science of Macroeconomics
Macroeconomics does not try to answer the question of:
why some countries experience rapid growth.
what is the rate of return on education.
why some countries have high rates of inflation. what
causes recessions and depressions.
A typical trend during a recession is that:
the unemployment rate falls. the popularity of the
incumbent president rises. incomes fall. the
inflation rate rises.
Macroeconomics is the study of the:
activities of individual units of the economy.
decisionmaking by households and firms. economy as a
whole. interaction of firms and households in the
marketplace.
The study of the economy as a whole is called:
household economics. business
economics. microeconomics.
macroeconomics.
The ability of macroeconomists to predict the future course of economic events: is no
better than a meteorologist's ability to predict the next month's weather. is much better
than a meteorologist's ability to predict the next month's weather. has gotten worse over
time. is less precise than it was in the 1920s.
All of the following except are important macroeconomic variables. real GDP the
unemployment rate the marginal rate of substitution the inflation rate
, The total income of everyone in the economy adjusted for the level of base year prices is called:
a recession. an inflation. real GDP. a business fluctuation.
A measure of how fast the general level of prices is rising is called the:
growth rate of real GDP.
inflation rate.
unemployment rate.
market-clearing rate.
The inflation rate is a measure of how fast: the total income
of the economy is growing. unemployment in the
economy is increasing. the general level of prices in
the economy is rising.
the number of jobs in the economy is expanding.
Real GDP over time, and the growth rate of real GDP .
grows; fluctuates is steady; is steady grows; is steady is steady; fluctuates
Two striking features of a graph of U.S. real GDP per capita over the twentieth century are the:
overall upward trend interrupted by a large downturn due to the economic depression in the
1930s.
nearly constant level with a large downturn in the 1930s.
downward trend in the first half of the century followed by the upward trend in the second
half. constant level in the first half of the century followed by the upward trend in the
second half.
In the U.S. economy today, real GDP per person, compared with its level in 1900, is about:
50 percent higher.
twice as high. three
times as high.
eight times as high.
Recessions are periods when real GDP:
increases slowly.
increases rapidly.
decreases mildly.
decreases severely.
Compared with real GDP during a recession, real GDP during a depression:
increases more rapidly. increases at
approximately the same rate. decreases at
approximately the same rate. decreases more
severely.

,A severe recession is called a(n):
depression. deflation.
exogenous event. market-
clearing assumption.
The annual inflation rate in the United States averaged:
nearly zero between 1900 and 1950. nearly
zero between 1950 and 2000. about 10
percent between 1900 and 1950. about 10
percent between 1950 and 2000.
Deflation occurs when:
real GDP decreases. the
unemployment rate decreases. prices
fall. prices increase but at a slower
rate.
A period of falling prices is called:
deflation.
inflation. a
depression.
a recession.
A graph of the rate of inflation in the United States over the twentieth century shows: an overall
upward trend interrupted by a large downturn in the 1930s.
some periods of deflation mixed with mostly positive rates of inflation before 1955 but only positive
rates of inflation after 1955.
a relatively steady, positive level throughout the century except for deflation in the 1930s.
a constant rate of inflation in the first half of the century followed by an upward trend in the
second half.
A graph of the U.S. unemployment rate over the twentieth century shows:
an overall upward trend in the unemployment rate interrupted by a large upturn in the 1930s.
an overall downward trend in the unemployment rate interrupted by a large upturn in the
1930s. rates of unemployment always greater than zero with substantial variations from year
to year.
alternating periods of positive and negative rates of unemployment.
Which of the combinations listed is not a U.S. president and an important economic issue of his
administration?
President Carter, inflation
President Reagan, budget deficits
President G. H. W. Bush, budget deficits
President Clinton, inflation
All of the following are types of macroeconomics data except the:

rate of real GDP. inflation
rate. unemployment rate.
During the period between 1900 and 2000, the unemployment rate in the United States was highest in the:
1920s.
1930s.
1970s.
1980s.
The unemployment rate:
was zero during the 1990s in the United States. was zero on average
between 1900 and 1950 in the United States.
has never been zero in the United States. is usually zero when the economy
is not in a recession or depression.
Exogenous variables are:
determined outside the model.
determined within the model. the
outputs of the model.
explained by the model.
Endogenous variables are:
fixed at the moment they enter the model.
determined within the model. the inputs of the
model.
from outside the model.
In an economic model:
exogenous variables and endogenous variables are both determined outside the
model. endogenous variables and exogenous variables are both determined within
the model.
endogenous variables affect exogenous variables.
exogenous variables affect endogenous variables.
Variables that a model tries to explain are called:
endogenous.
exogenous. market
clearing. fixed.
Important characteristics of macroeconomic models include all of the following except:
