Based on the definition of real GDP, do you predict real GDP should be higher or
lower than nominal GDP?

SO HOW DO WE CALCULATE REAL GDP?
• Choose a base year and use the prices from the base year to calculate GDP in following years.● India changed base year recently . . .
• This fixes prices so that changes in GDP in later years are caused only by a change in growth (production) and NOT caused by price changes (inflation).

Real vs. Nominal GDP Example2008
10 cars at $15,000 each = $150,00010 trucks at $20,000 each = $200,000Nominal GDP = $350,000
200910 cars at $16,000 each = $160,00010 trucks at $21,000 each= $210,000Nominal GDP = $370,000
The GDP in year 2008 shows the dollar value of all final goods produced.
The nominal GDP in year 2009 is higher which suggests that the economy is improving. But how much is the REAL GDP? How do you get it?
Use 2008 Prices.The Real GDP for 2009 is the same as 2008 after we adjust for inflation.
200910 cars at $15,000 each = $150,00010 trucks at $20,000 each= $200,000REAL GDP = $350,000

From NYTimes, Sept. 24, 2018:FACT CHECK OF THE DAY
Trump’s Inaccurate Claim That U.S. Is ‘the Fastest-Growing Economy in the World’The United States’ G.D.P. growth is nowhere near the highest in the world, though its rate is currently one of the highest among developed economies.
And the data says . . . .

Price Index and GDP Deflator
▪ A Price Index – used to measure inflation from an agreed upon base year’s prices
▪ GDP Deflator:▪ Reflects changes in the prices of goods and services
but not quantities produced▪ Used to monitor average level of prices in the economy
and thus inflation

CHAPTER 23 MEASURING A NATION’S INCOME
The GDP Deflator▪ The GDP deflator measures the changes in
prices for all of the goods and services produced in an economy. Therefore, it measures the overall level of prices in an economy.
▪ Formula:
GDP deflator = 100 x nominal GDPreal GDP
![Page 12: Create an index card on GDP that includes the …...difference between real and nominal GDP Learning targets: I can calculate real GDP using a base year and the GDP deflator.

What does GDP Deflator show us and how can we use it?● If nominal GDP shows us changes in
quantities produced and changes in prices (QxP)
● If real GDP shows us changes in quantities only (P)
● Then it follows that the GDP Deflator shows us changes in price!
QxP = P Nominal = GDP Defl. Q Real

What does GDP Deflator show us and how can we use it?
▪ One way to measure the economy’s inflation rate is to compute the percentage change in the GDP deflator from one year to the next:
GDP Def Y2 - GDP Def Y1 x 100 = Inflation!GDP Defl Y1

▪ Formula for Real GDP▪ (Nominal GDP÷GDP Deflator) X 100
▪ Formula for GDP Deflator: ▪ (Nominal GDP÷Real GDP) X 100
▪ Formula for Real GDP per capita:▪ Real GDP÷Population
▪ Formula for GDP Growth Rate▪ (Real GDP Year 2 – Real GDP Year 1) ÷ (Real GDP

Does GDP accurately measure standard of living?
Standard of living can be measured, in part, by how well the economy is doing…
But it needs to be adjusted to reflect the size of the nation’s population.
GDP Per Capita (per person) GDP divided by the population.
GDP per capita is measure of a nation’s standard of living.
❖ So what countries have the highest GDP per capita?
