Document Summary

By the end of this chapter, you will be able to: Construct a cpi and calculate the inflation rate [1/11 lecture] Adjust nominal quantities for the effects of inflation. List some biases in the official measure of inflation. It is a way to measure the price level and to calculate the rate of inflation. It is also a useful gauge of the cost of living. The cpi calculates the cost of a standard set ( basket ) of goods and services relative to the cost of that same set of goods and services in a fixed year, called the base year. Example: suppose the typical household has the following monthly purchases. Now let"s see the prices they have to pay in 2016 for the same basket of goods. Then we calculate the cpi in 2016 as follows: 100 x (cost of the basket in 2016) (cost of the same basket in 2010)

. Suppose a basket of goods and services has been selected to calculate the CPI and 2014 has been selected as the base year. In 2013, the basketâs cost was $80; in 2014, the basketâs cost was $86; and in 2015, the basketâs cost was $90. The value of the CPI in 2015 was

Suppose a basket of goods and services has been selected to calculate the CPI and 2012 has been chosen as the base year. In 2012, the basketâs cost was $80.00; in 2013, the basketâs cost was $84; and in 2014, the basketâs cost was $87.60. The value of the CPI was

All of the above are correct.

109.5 in 2014.

Which of the following is correct?

The CPI is better than the GDP deflator at reflecting the goods and services bought by consumers.

The GDP deflator is better than the CPI at reflecting the goods and services bought by consumers.

The GDP deflator and the CPI are equally good at reflecting the goods and services bought by consumers.

The GDP deflator is more commonly used as a gauge of inflation than the CPI is.

The inflation rate is defined as the

percentage change in the price level from the previous period.

price level in an economy.

change in the price level from one period to the next.

price level minus the price level from the previous period.

Economists use the term inflation to describe a situation in which

the economy's overall price level is rising.

some prices are rising faster than others.

the economy's overall price level is high, but not necessarily rising.

the economy's overall output of goods and services is rising faster than the economy's overall price level.

Measures of Inflation The GDP deflator is the broadest, most inclusive measure of change in the country's price level since it includes all final goods and services produced and sold. But the GDP deflator is not used by the government or economists as the benchmark measure of inflation; instead, the consumer price index (CPI) is used to determine changes in the cost of living. What is the shortcoming of the GDP deflator as a measure of inflation for households, and why is the CPI considered to be a more useful measure?
