Chapter 1
 
1.   a. True.
 b. True.
 c. False.
 d. True.
 e. False.
 f. False.
 
2.  a.   1960-98       1997-99
             ----------      ---------
US            3.1%           3.8%
EU            3.1%           2.5%
Japan         5.8%          -1.0%
 
While the US growth rate higher than its long-run average over the period, the growth rate has
slowed relative to long-run averages in both the EU and Japan over the last few years.
 Chapter 2
 
1. a. False.
 b. Uncertain: real or nominal GDP.
 c. True.
 d. True.
 e. False.  The level of the CPI means nothing.  Its rate of change tells us about inflation.
f.  Uncertain.  Which index is better depends on what we are trying to measure—inflation faced
by consumers or by the economy as a whole.  
 
2. a. +$100; Personal Consumption Expenditures
 b. no change: intermediate good
 c. +$200 million; Gross Private Domestic Fixed Investment
 d. +$200 million; Net Exports
 e. no change: the jet was already counted when it was produced, i.e., presumably when Delta
(or some other airline) bought it new as an investment.
 
*3. a. Measured GDP increases by $10+$12=$22. 
 b. True GDP should increase by much less than $22 because by working for an extra hour,
you are no longer producing the work of cooking within the house.  Since cooking within the
house is a final service, it should count as part of GDP. Unfortunately, it is hard to measure the
value of work within the home, which is why measured GDP does not include it.
