There’s been a lot of talk recently about consumer prices being squeezed by a lack of inflation. In fact, some economists believe the consumer price index, or CPI, may be falling. But is this really the case? What is the consumer price index, and how do we compute it?
A price index is a tool that measures the average price change for a particular item in a population or a sample of that population. There are two main types of price indices: the consumer price index (CPI) and the producer price index (PPI). Today, let’s talk about Consumer Price Index.
What is the Consumer Price Index?
It’s the measure of how much prices change over time. The CPI tracks the prices of a basket of goods and services used to determine the rate of a price change that occurs in the economy. It’s a useful tool to make sense of the cost of living for individuals, households, and government agencies. The nation’s economists use the CPI, business executives, the media, and the public to measure inflation and determine its impact on people’s lives.
The CPI tracks the average cost of a fixed basket of goods and services purchased by consumers in the US over time. One of the most widely used US government measures of inflation, the CPI, is used to calculate changes to the country’s minimum wage and Federal Poverty Level (FPL).
Why do you have CPI?
The consumer price index is a very important concept in economics, used to measure the change in the price level of a basket of goods and services purchased by households. CPI is a widely used tool to analyze inflation, however, it is also widely misunderstood.
The Federal Reserve uses the index to set its policy interest rates, which directly affect the cost of loans and mortgages. The CPI tracks the prices of a group of goods and services that consumers normally purchase. This includes everything from groceries to gas to healthcare. Over time, as prices change, the index changes as well.
Who computes or publishes CPI?
The Bureau of Labor Statistics in the United States publishes an index each quarter, and a new one is published each month. Confused? Let’s dig deeper.
The CPI measures prices paid by urban consumers on an average for a set of market basket of services and goods. This market basket is fixed for a two-year period. The current CPI is based on the consumer price index for all urban consumers, US city average, prepared by the Bureau of Labor Statistics, US Department of Labor.
The consumer price index is a measure of inflation over time with the purpose of evaluating whether inflation is still low. The formula for calculating the CPI is:
CPI = cost of products or services in a current period/cost of products or services in a previous time period x 100
A slight change in the Consumer Price Index (CPI) is computed as a kink in the most widely followed and quoted measure of inflation. The CPI is used to adjust wages and determine eligibility for some types of government benefits. Since the change, the CPI has been lower than the Federal Reserve’s target, which can be an issue when the Fed is trying to guide the economy toward full employment.
Wholesale Price Index and Consumer Price Index: What are their differences?
The Wholesale Price Index (WPI) measures the changes in prices of goods at the wholesale or trader level before they reach the final consumers. Let’s understand this with the help of an example. In case a business selling wholesale Bulk lighters, the WPI would track the prices at which the manufacturer or distributor sells the lighters to retailers or other traders.
A lighter manufacturer sells a box of 100 lighters to a retail store for $50, and the next month they increase the price to $55 for the same quantity, the WPI would reflect this increase in the wholesale price of lighters.
On the other hand, the Consumer Price Index (CPI) measures the changes in prices of goods and services at the retail or consumer level. In the case of lighters, the CPI would track the prices at which the retail stores sell individual lighters to the final consumers.
Let’s say a retail store buys a box of 100 lighters from the manufacturer for $50 and sells each lighter to consumers for $1. If the store raises the price of each lighter to $1.10 due to the increase in the wholesale price, the CPI would reflect this increase in the retail price of lighters.
When it comes to inflation, why is CPI highly preferred to WPI?
From the very start, the CPI has been controversial. Its critics believe it is flawed and is used to reduce the inflation rate rather than being a true measure of inflation. To this day, many economists support the idea that a true inflation rate should be calculated by using the GDP deflator, as most of them do not believe that the CPI is a good measure of inflation.
