Real v. Nominal GDP

AP Macroeconomics › Real v. Nominal GDP
A nation's nominal GDP increases from $$200 billion to $$210 billion, while the GDP deflator increases from 100 to 105. Which of the following is true regarding its real GDP?
Real GDP remained constant at $$\200$$ billion.
Real GDP increased from $$200 billion to $$205 billion.
Real GDP decreased from $$200 billion to $$190.5 billion.
Real GDP increased from $$200 billion to $$210 billion.
Explanation
Calculate real GDP for both years. Year 1 is the base year since the deflator is 100, so Real GDP = Nominal GDP = $$\200 billion. For Year 2, Real GDP = ($$210 billion / 105) x 100 = $$\200$$ billion. Thus, real GDP remained constant.
If an economy's nominal GDP increased by 7% in a year while its real GDP increased by 3%, what can be concluded about the price level during that year?
The price level, as measured by the GDP deflator, increased by approximately 10%.
The price level, as measured by the GDP deflator, remained constant.
The price level, as measured by the GDP deflator, decreased by approximately 4%.
The price level, as measured by the GDP deflator, increased by approximately 4%.
Explanation
The percentage change in nominal GDP is approximately equal to the percentage change in real GDP plus the inflation rate (percentage change in the price level). Therefore, Inflation Rate ≈ %Δ Nominal GDP - %Δ Real GDP. In this case, 7% - 3% = 4%. This indicates an increase in the overall price level.
A news report states that a nation's gross domestic product has increased significantly from the previous year. To assess whether the standard of living for the average person in the country has actually improved, it is most critical for an economist to analyze the change in
the balance of payments.
real GDP per capita.
nominal GDP and the distribution of income.
the national debt.
Explanation
An improvement in the standard of living implies that, on average, more goods and services are available per person. The best measure for this is real GDP per capita, which adjusts total output for both inflation (using real GDP) and population growth (per capita). The news report likely refers to nominal GDP, which is insufficient for this analysis.
Suppose 2018 is used as the base year for calculating real GDP. If the GDP deflator for 2023 is 125, and nominal GDP for 2023 is $$\25$$ trillion, what is the real GDP for 2023 expressed in 2018 dollars?
$$\31.25$$ trillion
$$\12.5$$ trillion
$$\25$$ trillion
$$\20$$ trillion
Explanation
The formula to calculate real GDP is (Nominal GDP / GDP Deflator) x 100. Using the provided numbers: ($$25 trillion / 125) x 100 = $$0.2 trillion x 100 = $$\20$$ trillion.
Assume a country produces the same quantity of final goods and services in Year 2 as it did in Year 1, but the average price of these goods and services has increased. Which of the following statements is correct?
Nominal GDP increased, and real GDP remained constant.
Nominal GDP decreased, and real GDP remained constant.
Nominal GDP remained constant, and real GDP increased.
Nominal GDP and real GDP both increased.
Explanation
Real GDP measures the quantity of production, so if the quantity is unchanged, real GDP remains constant. Nominal GDP measures the value of production at current prices. If prices increase while quantity stays the same, the total value (Nominal GDP) will increase.
The GDP deflator is a price index that measures changes in the average level of prices of
raw materials and other inputs purchased by producers.
a fixed basket of consumer goods and services purchased by urban households.
stocks and bonds traded on the nation's primary financial exchanges.
all final goods and services produced domestically in an economy.
Explanation
The GDP deflator reflects the prices of all final goods and services produced within a country. This makes it a broader measure of inflation than the Consumer Price Index (CPI), which only considers a fixed basket of consumer goods (A). Choice (D) describes a Producer Price Index (PPI).
Under which of the following circumstances would the change in nominal GDP be the best approximation of the change in real GDP?
When the overall price level in the economy is stable.
When the economy is experiencing a high and rising rate of inflation.
When the central bank is actively pursuing contractionary monetary policy.
When the economy is in a deep recession with high unemployment.
Explanation
If the price level is stable, the inflation rate is zero. Since the change in nominal GDP reflects changes in both price and output, a stable price level means that any change in nominal GDP is due solely to a change in real output. Therefore, the two measures would change by the same amount.
The calculation of real GDP, as opposed to nominal GDP, is essential for
calculating the size of the national debt relative to the current value of production.
determining the level of government tax revenues in current dollars.
assessing the profitability of a nation's corporations in a specific fiscal year.
making meaningful comparisons of economic output across different time periods.
Explanation
The primary purpose of real GDP is to facilitate comparisons of production over time by removing the distorting effect of price changes. By holding prices constant, we can see if the actual volume of goods and services produced has increased, decreased, or stayed the same.
Which of the following best defines real gross domestic product (GDP)?
The total value of all final goods and services produced within a country's borders in a given year, measured using the prices of the current year.
The total value of all final goods and services produced within a country's borders in a given year, measured using the prices of a base year.
The total value of all production within a country, adjusted for population growth and reported on a per capita basis.
The total income earned by a country's citizens, including income from abroad, adjusted for changes in the unemployment rate.
Explanation
Real GDP measures an economy's production of final goods and services valued at constant, or base-year, prices. This adjustment removes the effects of inflation, providing a clearer picture of changes in output. Choice (B) describes nominal GDP. Choices (C) and (D) describe different economic measures (GDP per capita and GNP adjusted for unemployment, respectively).
In a given year, a country's nominal gross domestic product is $$12 trillion and its real gross domestic product is $$10 trillion. What is the value of the GDP deflator for that year?
1.2
20
83.3
120
Explanation
The formula for the GDP deflator is (Nominal GDP / Real GDP) x 100. Plugging in the given values: ($$12 trillion / $$10 trillion) x 100 = 1.2 x 100 = 120. The GDP deflator is an index number.
