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.
Is it necessary to adjust GDP for inflation?
The BEA’s real GDP headline data is used by economists for macroeconomic research and central bank planning. The fundamental distinction between nominal and real GDP is the inclusion of inflation. No inflation adjustments are required because nominal GDP is estimated using current prices. This makes calculating and analyzing comparisons from quarter to quarter and year to year more easier, though less useful.

What is the formula for calculating inflation?
Last but not least, simply plug it into the inflation formula and run the numbers. You’ll divide it by the starting date and remove the initial price (A) from the later price (B) (A). The inflation rate % is then calculated by multiplying the figure by 100.
How to Find Inflation Rate Using a Base Year
When you calculate inflation over time, you’re looking for the percentage change from the starting point, which is your base year. To determine the inflation rate, you can choose any year as a base year. The index would likewise be considered 100 if a different year was chosen.
Step 1: Find the CPI of What You Want to Calculate
Choose which commodities or services you wish to examine and the years for which you want to calculate inflation. You can do so by using historical average prices data or gathering CPI data from the Bureau of Labor Statistics.
If you wish to compute using the average price of a good or service, you must first calculate the CPI for each one by selecting a base year and applying the CPI formula:
Let’s imagine you wish to compute the inflation rate of a gallon of milk from January 2020 to January 2021, and your base year is January 2019. If you look up the CPI average data for milk, you’ll notice that the average price for a gallon of milk in January 2020 was $3.253, $3.468 in January 2021, and $2.913 in the base year.
Step 2: Write Down the Information
Once you’ve located the CPI figures, jot them down or make a chart. Make sure you have the CPIs for the starting date, the later date, and the base year for the good or service.
Is a higher or lower GDP preferable?
Gross domestic product (GDP) has traditionally been used by economists to gauge economic success. If GDP is increasing, the economy is doing well and the country is progressing. On the other side, if GDP declines, the economy may be in jeopardy, and the country may be losing ground.
Why should inflation concern me?
Assume you’ve just discovered a $10 bill you hid away in 1990. Since then, prices have climbed by around 50%, so your money will buy less than it would have when you put it aside. As a result, your money has depreciated in value.
When the purchasing power of money decreases, it loses value. Because inflation is a rise in the level of prices, it reduces the amount of goods and services that a given amount of money can buy.
Inflation diminishes the value of future claims on money in the same way that it reduces the value of money. Let’s say you borrowed $100 from a friend and pledged to repay it in a year. Prices, on the other hand, double throughout the year. That means that when you pay back the money, it will only be able to buy half of what it could have when you borrowed it. That’s great for you, but it’s not so great for the person who loaned you the money. Of course, if you and your friend had foreseen such rapid inflation, you may have agreed to repay a higher sum to compensate. When people anticipate inflation, they might change their future obligations to account for its effects. Unexpected inflation, on the other hand, benefits borrowers while hurting lenders.
People who must live on a fixed income, that is, an income that is predetermined through some contractual arrangement and does not alter with economic conditions, may be particularly affected by inflation’s influence on future claims. An annuity, for example, is a contract that guarantees a steady stream of income. Fixed income is sometimes generated via retirement pensions. Inflation reduces the purchasing power of such payouts.
Because seniors on fixed incomes are at risk from inflation, many retirement plans include indexed payouts. The dollar amount of an indexed payment varies with the rate of change in the price level. When the purchasing power of a payment changes at the same pace as the rate of change in the price level, the payment’s purchasing power remains constant. Payments from Social Security, for example, are adjusted to keep their purchasing power.
The possibility of future inflation can make people hesitant to lend for lengthy periods of time since inflation diminishes the purchasing value of money. The risk of a long-term commitment of cash, from the lender’s perspective, is that future inflation will obliterate the value of the sum that will finally be repaid. Lenders are apprehensive about making such promises.
Uncertainty is especially strong in places where exceptionally high inflation is a concern. Hyperinflation is described as an annual inflation rate of more than 200 percent. Inflation of that scale quickly erodes the value of money. In the 1920s, Germany experienced hyperinflation, as did Yugoslavia in the early 1990s. People in Germany during the hyperinflation brought wheelbarrows full of money to businesses to pay for everyday products, according to legend. In Yugoslavia in 1993, a shop owner was accused of blocking the entrance to his store with a mop while changing the prices.
In 2008, Zimbabwe’s inflation rate reached an all-time high. Prices increased when the government printed more money and circulated it. When inflation started to pick up, the government decided it was “essential” to create additional money, leading prices to skyrocket. According to Zimbabwe’s Central Statistics Office, the country’s inflation rate peaked at 11.2 million percent in July 2008. In February 2008, a loaf of bread cost 200,000 Zimbabwe dollars. By August, the identical loaf had cost 1.6 trillion Zimbabwe dollars.
How do you boost your GDP?
- AD stands for aggregate demand (consumer spending, investment levels, government spending, exports-imports)
- AS stands for aggregate supply (Productive capacity, the efficiency of economy, labour productivity)
To increase economic growth
1. An increase in total demand
- Lower interest rates lower borrowing costs and boost consumer spending and investment.
- Increased real wages when nominal salaries rise faster than inflation, consumers have more money to spend.
- Depreciation reduces the cost of exports while raising the cost of imports, increasing domestic demand.
- Growing wealth, such as rising house values, encourages people to spend more (since they are more confident and can refinance their home).
This represents a rise in total supply (productive capacity). This can happen as a result of:
- In the nineteenth century, new technologies such as steam power and telegrams aided productivity. In the twenty-first century, the internet, artificial intelligence, and computers are all helping to boost productivity.
- Workers become more productive when new management approaches, such as better industrial relations, are introduced.
- Increased net migration, with a particular emphasis on workers with in-demand skills (e.g. builders, fruit pickers)
- Infrastructure improvements, greater education spending, and other public-sector investments are examples of public-sector investment.
To what extent can the government increase economic growth?
A government can use demand-side and supply-side policies to try to influence the rate of economic growth.
- Cutting taxes to raise disposable income and encourage spending is known as expansionary fiscal policy. Lower taxes, on the other hand, will increase the budget deficit and lead to more borrowing. When there is a drop in consumer expenditure, an expansionary fiscal policy is most appropriate.
- Cutting interest rates can promote domestic demand. Expansionary monetary policy (currently usually set by an independent Central Bank).
- Stability. The government’s primary job is to maintain economic and political stability, which allows for normal economic activity to occur. Uncertainty and political polarization can deter investment and growth.
- Infrastructure investment, such as new roads, railway lines, and broadband internet, boosts productivity and lowers traffic congestion.
Factors beyond the government’s influence
- It is difficult for the government to influence the rate of technical innovation because it tends to come from the private sector.
- The private sector is in charge of labor relations and employee motivation. At best, the government has a minimal impact on employee morale and motivation.
- Entrepreneurs are primarily self-motivated when it comes to starting a firm. Government restrictions and tax rates can have an impact on a business owner’s willingness to take risks.
- The amount of money saved has an impact on growth (e.g. see Harrod-Domar model) Higher savings enable higher investment, yet influencing savings might be difficult for the government.
- Willingness to put forth the effort. The vanquished countries of Germany and Japan had fast economic development in the postwar period, indicating a desire to rebuild after the war. The UK economy was less dynamic, which could be due to different views toward employment and a willingness to try new things.
- Any economy is influenced significantly by global growth. It is extremely difficult for a single economy to avoid the costs of a global recession. The credit crunch of 2009, for example, had a detrimental impact on economic development in OECD countries.
In 2009, the United States, France, and the United Kingdom all went into recession. The greater recovery in the United States, on the other hand, could be attributed to different governmental measures. 2009/10 fiscal policy was expansionary, and monetary policy was looser.
Governments frequently overestimate their ability to boost productivity growth. Without government intervention, the private sector drives the majority of technological advancement. Supply-side measures can help boost efficiency to some level, but how much they can boost growth rates is questionable.
For example, after the 1980s supply-side measures, the government looked for a supply-side miracle that would allow for a significantly quicker pace of economic growth. The Lawson boom of the 1980s, however, proved unsustainable, and the UK’s growth rate stayed relatively constant at roughly 2.5 percent. Supply-side initiatives, at the very least, will take a long time to implement; for example, improving labor productivity through education and training will take many years.
There is far more scope for the government to increase growth rates in developing economies with significant infrastructure failures and a lack of basic amenities.
The potential for higher growth rates is greatly increased by providing basic levels of education and infrastructure.
The private sector is responsible for the majority of productivity increases. With a few exceptions, private companies are responsible for the majority of technical advancements. The great majority of productivity gains in the UK is due to new technologies developed by the private sector. I doubt the government’s ability to invest in new technologies to enhance productivity growth at this rate. (Though it is possible especially in times of conflict)
Economic growth in the UK
The UK economy has risen at a rate of 2.5 percent each year on average since 1945. Most economists believe that the UK’s productive capacity can grow at a rate of roughly 2.5 percent per year on average. The underlying trend rate is also known as the ‘trend rate of growth.’
Even when the government pursued supply-side reforms, they were largely ineffective in changing the long-run trend rate. (For example, in the 1980s, supply-side policies had minimal effect on the long-run trend rate.)
The graph below demonstrates how, since 2008, actual GDP has fallen below the trend rate. Because of the recession and a considerable drop in aggregate demand, this happened.
- Improved private-sector technology that allows for increased labor productivity (e.g. development of computers enables greater productivity)
- Infrastructure investment, such as the construction of new roads and train lines. The government is mostly responsible for this.
What causes GDP to increase?
Higher production leads to lower unemployment, which fuels demand even more. Increased earnings contribute to increased demand as customers are more willing to spend. This leads to a rise in both GDP and inflation.
What is the most accurate inflation indicator?
Because of the multiple ways the CPI is used, it has an impact on practically everyone in the United States. Here are some instances of how it’s used:
As a measure of the economy. The CPI is the most generally used metric of inflation, and it is sometimes used as a gauge of government economic policy efficacy. It offers government, business, labor, and private citizens with information regarding price changes in the economy, which they use as a guide for making economic decisions. In addition, the CPI is used by the President, Congress, and the Federal Reserve Board to help them formulate fiscal and monetary policy.
Other economic series can be used as a deflator. Other economic variables are adjusted for price changes and translated into inflation-free dollars using the CPI and its components. Retail sales, hourly and weekly earnings, and components of the National Income and Product Accounts are examples of statistics adjusted by the CPI.
The CPI is also used to calculate the purchasing power of a consumer’s dollar as a deflator. The consumer’s dollar’s purchasing power measures the change in the value of products and services that a dollar will buy at different times. In other words, as prices rise, the consumer’s dollar’s purchasing power decreases.
As a technique of changing the value of money. The CPI is frequently used to adjust consumer income payments (such as Social Security), to adjust income eligibility limits for government aid, and to offer automatic cost-of-living wage adjustments to millions of Americans. The CPI has an impact on the income of millions of Americans as a result of statutory action. The CPI is used to calculate cost-of-living adjustments for over 50 million Social Security beneficiaries, military retirees, and Federal Civil Service pensioners.
The use of the CPI to change the Federal income tax structure is another example of how dollar values can be adjusted. These modifications keep tax rates from rising due to inflation. Changes in the CPI also influence the eligibility criteria for millions of food stamp recipients and students who eat lunch at school. Wage increases are often linked to the Consumer Price Index (CPI) in many collective bargaining agreements.
What is a low GDP rate?
Economists frequently agree that the ideal rate of GDP growth is between 2% and 3%. 5 To maintain a natural rate of unemployment, growth must be at least 3%.
