Explain why the sale of used goods is not included in GDP:
B.
Nominal and real GDP
You are an economist who has been asked to calculate your nations GDP, which produces only three
goods/services. Calculate nominal GDP for Year 1 and Year 2. GDP = Price x Quantity.
Year 1 Nominal GDP
Good
Oil changes
Hamburgers

\$150
Year 2 Nominal GDP

How much did nominal GDP increase from Year 1 to Year 2?

Now calculate Year 2 real GDP using Year 1 as the base year (that means you use Year 1 prices to calculate
Year 2s GDP)
Year 1 Real GDP

Price
Oil changes \$ 15
Hamburgers \$ 2
MP3 players \$150
Year 2 Rea1 GDP (Year 1 is the base year)

How much did Year 2s nominal GDP overstate GDP in Year 2 when compared to real GDP?
13.
How much did real GDP increase from Year 1 to Year 2?
14.
Why is it important to adjust nominal GDP to real GDP to account for inflation?
GDP
C. Assume that a country has a closed economy with only three goods/services (no next exports). In a
given year, the economy produces: a) three haircuts at \$10 each; b) two factory machines at \$100 each;
and c) one highway repair that costs \$500.
15.
What is total GDP for this economy?
16.
What percent of GDP is consumption?
17.
What percent of GDP is investment?
18.
What percent of GDP is government spending?
19.
Suppose an economys nominal GDP increased 3 percent in 2005. Why is this information alone not
enough to determine whether the economy experienced economic growth? What other information would you
need to determine that?
20.
Why is GDP not a true measure of the standard of living? What other factors should be considered
when determining a countrys standard of living?
