The GDP deflator (implicit price deflator for GDP) is a measure of the level of prices in an economy for all new, domestically produced final goods and services. It is a price index that is calculated using nominal GDP and real GDP to measure price inflation or deflation.
Nominal GDP versus Real GDP
The market worth of all final commodities produced in a geographical location, generally a country, is known as nominal GDP, or unadjusted GDP. The market value is determined by the quantity and price of goods and services produced. As a result, if prices move from one period to the next but actual output does not, nominal GDP will vary as well, despite the fact that output remains constant.
Real gross domestic product, on the other hand, compensates for price increases that may have happened as a result of inflation. To put it another way, real GDP equals nominal GDP multiplied by inflation. Real GDP would remain unchanged if prices did not change from one period to the next but actual output did. Changes in real production are reflected in real GDP. Nominal GDP and real GDP will be the same if there is no inflation or deflation.
How are the GDP deflator and real GDP calculated?
In general, real GDP is calculated by multiplying nominal GDP by the GDP deflator (R). For instance, if prices in an economy have risen by 1% since the base year, the deflated number is 1.01. If nominal GDP is $1 million, real GDP equals $1,000,000 divided by 1.01, or $990,099.
With an example, what is GDP deflator?
The real GDP is the measure of GDP that takes inflation into account. As a result, nominal GDP for year two would be $12 million, whereas real GDP would be $11 million in the case above. When comparing nominal and real GDP across time, the GDP price deflator aids in determining price changes.
How are the GDP deflator and CPI calculated?
Nominal/CPI x 100 is the formula. So a $100 television in 2017 would cost $70.59 in 1990 ($100/141.67=$70.59). You can use the percentage change formula to compute the amount of inflation between two deflators or CPIs.
Without actual GDP, how do you calculate the deflator?
We can calculate the actual GDP deflator now that we know both nominal and real GDP. To do so, multiply the result by 100 and divide nominal GDP by real GDP. This gives us the change in nominal GDP that cannot be attributable to changes in real GDP (from the base year). Take a look at the formula below:
Returning to our example, we can observe that the 2015 GDP deflator is 100 (*100). Because nominal and real GDP must be equal, the GDP deflator for the base year will always be 100. When we move ahead a few years, however, things start to get more intriguing. The GDP deflator for the year 2016 is 7 160.9 (*100). That is, the price level increased by 60.9 percent (160.9 100) from 2015 to 2016. Similarly, the GDP deflator for 2017 is 243.4, reflecting a 143.4 percent increase in price levels over the base year.
What is the formula for GDP?
Gross domestic product (GDP) equals private consumption + gross private investment + government investment + government spending + (exports Minus imports).
GDP is usually computed using international standards by the country’s official statistical agency. GDP is calculated in the United States by the Bureau of Economic Analysis, which is part of the Commerce Department. The System of National Accounts, compiled in 1993 by the International Monetary Fund (IMF), the European Commission, and the Organization for Economic Cooperation and Development (OECD), is the international standard for estimating GDP.
When the GDP deflator falls, what does it mean?
We need to know the nominal and real GDPs to calculate the GDP price deflator formula. The base year in the following example is 2010. The GDP deflator is then calculated each year using the formula: Nominal GDP / Real GDP x 100 = GDP price deflator
It’s worth noting that the GDP price deflator fell in 2013 and 2014. In comparison to the base year 2010, the growth in the aggregate level of prices is smaller in 2013 and 2014. The GDP deflator measures price inflation or deflation in comparison to the base year and hence reveals the impact of inflation on the GDP.
Is the GDP deflator the same as the rate of inflation?
The GDP deflator is the difference between the two years’ inflation ratesthe amount by which prices have risen since 2016. The deflator is named after the percentage that must be subtracted from nominal GDP to obtain real GDP.
How is the GDP deflator used to calculate inflation?
The deflator for the Gross Domestic Product (GDP) is a measure of overall price inflation. It’s determined by dividing nominal GDP by real GDP and multiplying by a factor of 100. The market value of goods and services produced in an economy, unadjusted for inflation, is known as nominal GDP (It is the GDP measured at current prices).
What is the link between the GDP deflator and the Consumer Price Index?
The final distinction is in how the two metrics combine the various prices in the economy. The CPI or RPI gives set weights to different goods’ prices, whereas the GDP deflator gives fluctuating weights. To put it another way, the CPI or RPI is calculated using a fixed basket of products, but the GDP deflator permits the basket of items to change over time as GDP composition changes. Consider an economy that only produces and consumes apples and oranges to show how this works.
Both the CPI and the GDP deflator compare the cost of a basket of products today to the cost of the same basket in the base year, as shown by these equations. The only difference between the two is whether the basket changes over time. The CPI is calculated using a set basket, but the GDP deflator is calculated with a variable basket. The following example illustrates the differences between both approaches.
Consider what happens if heavy frosts wipe out the nation’s orange crop: the number of oranges produced drops to zero, and the price of the few oranges that remain skyrockets. The increase in the price of oranges is not reflected in the GDP deflator since oranges are no longer included in GDP.
What distinguishes the CPI from the GDP deflator?
The GDP implicit price deflator multiplies GDP’s current nominal-dollar value by its chained-dollar value. 12 The chained-dollar value is calculated by multiplying the change in the GDP quantity index by a base-period dollar value amount, which is calculated using a Fisher ideal index formula that aggregates component GDP quantity indexes. After calculating the component quantity indexes, the GDP quantity index can be determined, as well as the GDP implicit price deflator, which is obtained by dividing nominal GDP by real GDP. The GDP implicit price deflator changes at a rate that is roughly equal to the GDP price index. The GDP implicit price deflator has risen at a systematically lower rate than the CPI-U over time (2 percent annually for the GDP price index and implicit price deflator, versus 2.4 percent annually for the CPI-U), in part because the CPI-U uses a Laspeyres aggregation while the GDP implicit price deflator uses a Fisher ideal aggregation, as shown in figure 1.
Summary
Alternative measurements of inflation in the US economy include the CPI, GDP price index, and implicit price deflator. Which one to choose in a given circumstance is likely to be determined by the set of commodities and services in which one is interested as a price change measure. The CPI is a price index that analyzes price changes from the perspective of a city consumer and hence applies to products and services that are purchased out of pocket by city residents. The GDP price index and implicit price deflator track price changes in products and services produced domestically, and so apply to goods and services purchased by consumers, businesses, the government, and foreigners, but not importers. Furthermore, the formulas utilized to calculate these two measurements are not the same.
