Explain what a price index is and how to compute one; Calculate inflation rates using price indices
22 cze 2022 · Constructing any price index involves other, less obvious, decisions. For instance, the CPI and PCE both adjust prices to account for changing quality (a decision the BLS 1 and BEA 2 have defended against frequent misconceptions). They both seasonally adjust price changes, though in slightly different ways. They also change the composition of ...

Give a weighting to the importance of different goods to the typical basket of goods. Convert into the index – multiplying the weight by the price change.
An inflation rate can be computed for any price index using the general equation for percentage changes between two years, whether in the context of inflation or in any other calculation: From Year 1 to Year 2, the price index in Table 2 rises from 93.4 to 99.5.
The Consumer Price Index (CPI) and the Producer Price Index (PPI) are commonly used inflation indices. The CPI reflects changes in the prices of goods and services typically purchased by consumers. The PPI reflects changes in the revenue that producers receive for goods and services.
At a glance, you can see that the index numbers would now exactly match the dollar figures, and the inflation rate in the first period would be 6.5%. Now that we see how indexes work to track inflation, the next module will show us how economists measure the cost of living.
14 cze 2023 · The formula to calculate an exponential rise such as inflation is: Or. P = original price. r = rate of inflation. n = number of periods. Note that the period length is flexible: it could be months, years, weeks – it doesn’t matter, so long as the inflation rate corresponds with the period.
