Document Summary

Key macro variables: gdp: measuring the price level. The gdp deflator: ratio of nominal gdp to real gdp, times 100, gdp deflator = (nominal gdp/real gdp) x 100, the deflator would be equal to 100 in the base year, inflation. Inflation = ((p in later year - p in earlier year) / (p in earlier year)) x100. Inflation = ((gdp deflator in 2006 - gdp deflator in 2005) / (gdp deflator in 2005)) x. ((128. 6-114. 6) / 114. 6 )) = 12. 2: consumer price index (cpi) Does not have any meaning in and of itself, needs to be connected to something. Cpi measures changes in things that the average consumer actually buys. How the bls (bureau of labor studies) constructs the cpi: survey consumers to determine composition of the typical consumers basket of goods. ((cost of basket in that month) / (cost of basket in the base period)) x 100. 2016 cpi = (410/350) x 100: calculating the inflation rate w cpi.

Suppose that the are two goods in the economy, Xylophones (X) and Yams (Y). In year t, consumers in the economy purchase 20 Xylophones at a price of $20 each and 100 Yams at a price of $2 each. In year t + 1, consumers in the economy purchase 18 Xylophones at a price of $30 each and 150 Yams at a price of $2.50 each.

1. Calculate the GDP deflator in years t and t + 1 with base year t. What is inflation according to this deflator? Show each step. (Hint: it will be helpful for you to first calculate nominal and real GDP in years t and t + 1. When you calculate real GDP, make sure that you use the appropriate base year).

2. Calculate the GDP deflator in years t and t + 1 with base year t + 1. What is inflation according to this deflator? Show each step. (Hint: you will need to calculate real GDP in years t and t + 1 using a different base year than you used in part 1. Once you calculate real GDP with the appropriate base year, you will follow the same steps that you did in part 1.)

3. Compare your answers to a and b above. Are they the same? If not, why not? How does chain-weighting address any potential difference?

4. Calculate the CPI in years t and t + 1, using year t as the base year.

5. Describe two ways in which the CPI differs from the GDP deflator.

6. There are several problems with using the CPI to calculate real GDP and measure growth. One of these problems is that the CPI does not account for changes in the quality of goods sold over time. A computer today is significantly more efficient than it was even just ten years ago, so even if the price of computers rise with inflation, you are getting significantly more computing power per dollar. How would this bias estimates of GDP growth and inflation?

The table below lists annual consumer price index and inflation rates for a country over the period 2005-2010. Assume the year 2005 is used as the base year.

. 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

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.
