Describe how price indexes are calculated and define the key types of price indexes
Consider the diagram below. The line represents the economy's growth trend, and the curve represents the economy's actual course of business fluctuations. For each part below, provide the letter label from the portion of the curve that corresponds to the associated term.

At present, the nominal interest rate is 7 per cent, and the expected inflation rate is 5 per cent. The current year is the base year for the price index used to calculate inflation.
a. What is the real interest rate?
b. What is the anticipated value of the price index next year?
In 2016, the cost of a market basket of goods was \(2,000. In 2018, the cost of the same market basket of goods was \)2,100. Use the price index formula to calculate the price index for 2018 if 2016 is the base year.
If each household in a nation were to track a consumer price index that averaged the prices of items consumed solely by that household, why would you anticipate that the annual rate of change of every household's average prices likely would differ?
