QUESTION 1
What is the primary measure of the market value of all final goods
and services produced within a country in a given period?
A) Consumer Price Index (CPI)
B) Gross Domestic Product (GDP)
,C) Gross National Product (GNP)
D) Net National Product (NNP)
ANSWER: B) Gross Domestic Product (GDP)
EXPLANATION: GDP is the standard measure of the value of final
goods and services produced within a country's borders during a
specific time period. It includes consumption, investment,
government spending, and net exports. GDP can be measured using
the expenditure approach (C+I+G+NX), the income approach, or the
value-added approach .
QUESTION 2
Which of the following is NOT included in GDP?
A) Government spending on infrastructure
B) Consumer purchases of new cars
C) Sales of used goods
D) Business investment in new equipment
ANSWER: C) Sales of used goods
EXPLANATION: GDP measures the value of newly produced final
goods and services. Sales of used goods represent transfers of
existing assets and are not counted in GDP because they do not
represent current production. Similarly, financial transactions and
transfer payments are not included in GDP .
,QUESTION 3
In the expenditure approach to calculating GDP, what does the 'C'
stand for?
A) Corporate profits
B) Capital investment
C) Consumption expenditure by households
D) Capital consumption allowance
ANSWER: C) Consumption expenditure by households
EXPLANATION: The expenditure approach to GDP is represented by
the formula GDP = C + I + G + NX, where C is consumption spending
by households on goods and services, I is investment spending on
capital goods, G is government spending, and NX is net exports
(exports minus imports). Consumption is typically the largest
component of GDP .
QUESTION 4
Real GDP differs from nominal GDP in that real GDP:
A) Includes only goods and services produced domestically
B) Is adjusted for changes in the price level
C) Includes only services produced
D) Is measured at current market prices
, ANSWER: B) Is adjusted for changes in the price level
EXPLANATION: Real GDP is nominal GDP adjusted for inflation,
allowing comparison of economic output across different years by
holding prices constant. Nominal GDP is measured using current-
year prices, which can change due to inflation. Real GDP is a better
measure of actual changes in production quantity .
QUESTION 5
If nominal GDP increases by 5% and real GDP increases by 3%, what
is the approximate inflation rate?
A) 2%
B) 5%
C) 3%
D) 8%
ANSWER: A) 2%
EXPLANATION: The relationship between nominal GDP, real GDP, and
inflation is: %ΔNominal GDP ≈ %ΔReal GDP + %ΔPrice Level
(Inflation). Therefore, inflation ≈ 5% - 3% = 2%. This is the GDP
deflator approach to measuring inflation .
